“Clean” installation of MacOS X on PC

“Clean” installation (in the original. Vanilla Installation) allows you to install the system without changing the files of the main section, only adding the bootloader and the necessary drivers to the hidden section of the EFI disc. In this case, the section with the installed MacOS X remains unnecessary.

This manual is designed for desktop PC. For laptops, it is better to look for something else (there are your subtleties and features there). Most of the modern iron based on Intel processors is compatible with such an experiment.

  • EFI is a hidden disk section used on MAC computers to storage firmware. Hackintosh is used to accommodate the OC bootloader on PC.
  • Clover. this is the bootloader that we will use. It indicates a section with the installed MacOS X as a load, and also uploads the necessary drivers and corrections.
  • Config.PLIST. configuration file for Clover. He will tell the system what MAC is configured (Mac Pro, Mac Mini or IMAC), will make the necessary corrections to the ACPI branch, and the drivers will propagate if necessary.
  • Kexts. derivative of the words Kernel Extensions. By simple speaking, drivers.
  • The image of MacOS X downloaded from Apple Store: Mojave, Catalina.
  • 8 GB flash drive for Mojave and 16 GB for Catalina The bootloader itself Utility to edit config.PLIST, open the hidden section EFI and much more.

We wash the flash drive in the disk utility with parameters:

Run Terminal and copy the command to create a loading flash drive:

Sudo “/Applications/Install Macos Mojave.App/contens/Resources/Createinstallmedia “.-Volume /Volumes /USB

Enter the password, click “Y” and wait a few minutes.

After the end of the file transfer process, we get a flash drive with which you can install MacOS X on Mac computers. To install MacOS X on PC, we need to add Clover bootloader and the necessary drivers.

Now you need to run the previously downloaded Clover installer, enter the password and at the third stage of the installation. select “Change the installation” and point to the “Install MacOS Mojave” flash drive.

At the fourth stage of the installation “type of installation”, click “configure” and select five parameters:

Install Clover only for UEFI loading.

After installation, the EFI connected section will appear on the desktop. You don’t need to turn it off. It will come in handy for us. You need to check that in the/Volumes/EFI/Clover/Drivers/UEFI folder (at least) there are three drivers: APFSDRIVERLOADER, APTIOMEMORYFIX and VBOXHFS. If so, everything is done correctly. If not, you need to rewind and repeat the Clover installation.

    , Or FakeSmc.KEXT. the minimum necessary driver for loading. It emulates the MAC SMC, saying that the operating system is that everything with a beam is Mac. Without it, loading is impossible.
    – solves the issues of support for both discrete graphic adapters and built.in graphics. Works in tandem with Lilu.KEXT. Starting with MacOS X Mojave, Apple refused to support NVIDIA adapters, but added support to AMD RX 5xx and 5xxx. If you have a NVIDIA adapter, then you can try to install an earlier version of OS. For example, High Sierra.

  • Mac computers are not famous for the special variety of wi-fi and Bluetooth combo-chips. By and large, here the choice is only from Broadcom or Broadcom adapters. I highly recommend using the BCM94360CS2 adapter. These chips are used on MacBook and work “out of the box”. Only you need to be puzzled by the adapter from this adapter to the connector m.2.
  • Otherwise, you can use adapters m.2 series BCM94352Z with AirPortbrcmfixup.KEXT paired with Lilu.KEXT-for Wi-Fi, BRCMFIRMWAREDATA.KEXT and BRCMPATCHRAM2.KEXT. for Bluetooth.

Now you need to copy downloaded drivers into the/Volumes/EFI/Clover/KEXTS/OTER folder.

The config file is used to configure the system.PLIST. It is registered at/Volumes/EFI/Clover. After installation, Clover creates its own config.PLIST, but the chances of loading with it are small. There are a huge number of unnecessary ones that can conflict with the system and drivers.

Based on some experience of trial installations on various configurations, I prepared my config.PLIST, which you can download here. It is almost empty, the main task is to determine the closest similar configuration of the Mac computer to your PC configuration, generate serial number and uuid. To do this, we will use Clover Configurator.

How to install macos 10.15 Catalina on Mac with USB flash drive

In this article we will tell you how to install MacOS 10.15 Catalina on Mac with USB flash drive. MacOS 10.15 Catalina is already available for downloading on all supported Mac models. You can download the update “by air”, but this is not the only way.

You can install MacOS from scratch to get rid of all the problems of the previous version. Below we will tell you how to do it.


  • Save all your necessary data. You can make a backup using Time Machine or copy everything manually. Be sure to save all your important documents and data on another medium.
  • Your Mac must support MacOS 10.15 Catalina. You will find a list of supported Mac models here.
  • MacOS Catalina does not support 32-bit programs, so some old programs may not work.

First you need an installer file. Download it from here: MacOS Catalina.

Now you need to record the installer on the USB flash drive. You can do this using our instructions.

When the flash drive with the installer is ready, turn off your Mac and insert a flash drive into it. Turn on the Mac by holding the Option key. There will be a launch menu in which you can choose a flash drive.

After a while, the MacOS utility menu will appear. Select a disc utility and click “Continue”.

Make sure that the main hard drive of your Mac is chosen, and then click wip. In the name of the disk, leave “Macintosh HD”, and select APFS or Mac OS Extended as a format. Click “erase” once again.

The hard drive was completely formatted. Now you need to fill it again. In the menu with utilities, select the reinstall MacOS and click “Continue”. Choose the newly formatted disk and follow the instructions on the screen.

That’s all! When the installation process ends, you will get a completely empty computer with MacOS 10.fifteen. Now you can re.install all programs and copy your documents and data back.

It is not possible to boot in Refit (to select Ubuntu) on Mac after updating Yosemite

I update Yosemite on MacBook Pro (13 inches, model mid.2012). After the update, I can’t boot in Refit, the OS option is not available, I just boot on the Mac OSX Yosemite directly.

  • I tried to reinstall the repair, it did not work.
  • I tried to install Refind with an argument.-ESP, as explained here. He also did not work.
  • I install Refind without any arguments, just run Install.SH, the message shows that it can be successfully installed, but nothing has changed.
  • I install Refind with.-Alldrivers, the message shows that it can be successfully established, but nothing changes.
  • I perform Diskutil Corestrage Revert / Dev / Disk1, as described here. He displays my Mac OSX Yosemite on the white screen only when loading. I read it from the recovery. Loading disk.

So, I would like to ask your people to help solve my problem. Ubuntu on Mac. This is my main equipment for the implementation of many of my work, so I need Ubuntu to be shown again when rebooting / restoring the load on the Mac. Here are the contents of my sections inspector, which I made from Refit.

My unknown sections were the root catalog Ubuntu (Ext4, Disk0S5) and another Ext section to save my data (Disk0S7). The recovery section should be DISK0S4 and Disk0S5 (both are HFS).

If you haven’t done this, try to start it on OSX Terminal

When the password is requested, use the one that Yosemite requests when trying to install new software.

After that, you should see the download menu after rebooting. When you decide to download UBUNTU from the download menu, you may welcome the GRUB Rescue Terminal instead of regular downloading, let me know.

By the way, you can also press the parameter (“ALT”) key immediately after pressing the power button, and there you will see some parameters, including reinstalling. This has a shortage that this should be done at each load, therefore, the preference of the terminal solution.

What do you mean by the installation “manually”? I installed the Refit DMG file as usual. I also did./Enable.SH in / efi / refit, but after rebooting nothing appears. When I press ALT (option) or META-R, EFI loading is shown, but it still freezes / freezes.

I did this, and it seemed to work, but then when uploading Ubuntu from Refit, I get a message on the black terminal with the message “No loading device. Insert the device and press any key “.

I had the same problem with MacBook Pro at the end of 2013. Refind worked for me with a team./Install.SH.-ESP.-Alldrivers. Although my first impression was that I failed. I just had to wait ~ 1 minute so that the pop.up menu surfaces during boot.

To avoid this long waiting for loading, you can make the following changes to your Refind installation.

  • Mount your ESP section. Mkdir /Volumes /Efi Sudo Mount.T MSDOS /DEV /Disk0S1 /Volume /EFI
  • Rename Refind Boot folder. for example. / Volumes / EFI / EFI / Refind becomes / volumes / EFI / EFI / BOOT
  • Rename the Refind_x64 file.EFI in BootX64.EFI. for example. /Volumes/EFI/EFI/Refind/Refind_x64.EFI becomes/Volumes/EFI/EFI/BOOT/BOOTX64.EFI

Break and restart. Enjoy! 🙂

./Install.SH.-EPS on Refind does not work for me because I can’t mount my EPS section. My EPS section was Disk0S1 when I tried to mount.T MSDOS / DEV / Desk0S1 / Volumes / EPS, he said: Mount_MSDOS: Unfinished sector (0). Any idea to solve this problem? Need your help, guys.

Mac loading through Refit, please try this command

After installing Refit, open the terminal and execute this command.

Successful update for double loading Mac / Yosemite Ubuntu has just been completed. Basically, the leadership http: // www.Rodsbooks.com/Refind/Yosemite.HTML is fine.

But note that from the choice of GRUB, available in Refit or its successor Refind, you could load more painstakingly with:

To display sections. For the aforementioned sections about the preservation of the Linux file system will be reported (GPT4 is really the fifth section):

and the standard Ubuntu Grub menu will be caused

Further Комментарии и мнения владельцев in this document provide a new option within the selection of Refind.

Pay attention to the information about the section above:

“Section 3” contains a new section of recovery version 10.10 with the ability to download LVM, as indicated in Yosemite.HTML. “Section 4”. This is the old version of the version 10.9 that is no longer needed! If you can reformat in HFS. and Refind can be installed in it.

Hold the point of the “Option” key after rebooting, and it will give out icons for 10.9 and 10.ten. Previously, under the Maverick, Windows icon was actually for the Ubuntu section, and I could download Ubuntu in this way. But with the update of Yosemite, this is no longer effective.

For unknown reasons, the standard “disk utility” did not separately reported a report on two sections of recovery. But my memory cannot be healthy in this matter. If the disk utility displays both recovery sections, the GDISK deletion procedure indicated below, you can skip. Just use the DISK Utility ERASE option to reformat section 4 in HFS named “EFI”.

As a preliminary installation http: // www.Rodsbooks.COM/ gdisk/ and, of course, the latest version of Refind. Use GDISK to carefully remove (in this case) section 4 (Mac OS X HFS), trying not to remove the replacement of Recovery 10.10 (Mac OS X Boot). This should be the usual Mac loading, starting with the saved section 3 and under the control of LVM, causing the main installation of the Mac “Section 2”.

Now use the standard “disco utility” to create a section of HFS in free space, which can be called “EFI”. It will be displayed as / Volumes / EFI / and is used to install Refind.

In my uninterled folder downloads/refind-bin-0.eight.3/ was launched:

Editing the Refind provided.Conf.sample, you should follow Yosemite.HTML:

Although your system does not need a delay, a change has also been made:

This allowed the MAC loading icon later, without the need for ESC for repeated scanning of sections. The saved file was called Refind.Conf.Edit my Gedit text editor for Mac, but any text editor should do what saves in a simple text.

Finally, the editing was copied (in one line), as shown below, reducing the original installed during the installation:

Make sure your edits are really within (say):

After rebooting, Refind menu appeared Ubuntu nucleus loading options. There are several non.working icons that I have not yet excluded on the display. But Ubuntu boots are in order.

Please, carefully read all the documentation mentioned above. My brief Комментарии и мнения владельцев here are not sufficient guidance. But we will summarize:

If Refit was saved, Ubuntu loading could be performed with:

To get a slower load, perform Refind installation steps and study this process.

How to Install macOS 10.15 Catalina on an Unsupported Mac

Termination of support for 32-bit applications

Apple announced the termination of support for 32-bit applications more than a year and a half ago, when MacOS High Sierra users began to receive warnings that 32-bit software is “not supported”.

The applications still worked, but at the presentation of Catalina on WWDC in June 2019, Apple officially announced the cessation of their support. As expected, after updating the system 32-bit applications ceased to be launched.

In this regard, a number of quite expected problems arose, although others became an unpleasant surprise. For example, in outdated versions of Adobe programs, such as Photoshop, some 32-bit licensing components and installers are used, so they refused to work after updating. Even the Adobe deinstal stopped working after installing Catalina, because it is also a 32-bit component.

Adobe recommends to refrain from installing the update if you have old versions of Photoshop or Lightroom created before Creative Cloud. The company also explains that in the case of installation of Catalina, you should probably remove the old software in advance, because later it will be difficult to get rid of it.

Of the other popular programs that are in such a trap are older versions of Microsoft Office, numerous outdated versions of Mac applications, such as GarageBand, and an application with a complete support term, such as iPhoto. Among the games for the MAC there are also quite a lot of 32-bit, and there is no way to save them after updating on Catalina.

Blogger Steve Moser compiled a list of 235 applications that are not supported in Catalina. Among them:

  • Transmit 4.one.7
  • 1password 2.12.2
  • Istats Menu 2.9
  • Box Sync 4.0
  • Quickbooks 2015
  • Default Folder X 4.3.ten
  • VMware Fusion 3.one.four
  • Creative Cloud 1.one.0.592
  • Parallels 2.5
  • Many antivirus programs

Problems of incompatibility Photoshop

But not only 32-bit applications affected the problems. Due to incompatibility bugs, even new versions of Photoshop, installed and controlled using Creative Cloud, have problems with file names, problems with checking the connected modules and with video visualization. Adobe reports on the support page that droplets, Extendscript Toolkit and Lens Profile Creator will not be able to work in the new version of MacOS. Adobe is now working on solving these problems.

If you select the file when exporting Render Video, then the process will begin, but never end.

MacOS Catalina errors and how to fix them

Apple released the MacOS Catalina update for Mac three months ago. The updated version presents new functions, including Sidecar, support for wireless gaming controllers, new applications for playing audio and video formats, the new Locator application and improved- “reminders”.

Some Mac users immediately update the OS, others go to the new version of MacOS only a few weeks after the release, to make sure that there are no problems in the update or they were corrected, or they prefer not to be updated.

The article collected obvious problems and errors of the new MacOS Catalina, which users face during or after installing the update.

How to fix MacOS Catalina errors

Errors when downloading and installing MacOS Catalina

Before downloading and installing the MacOS Catalina update from the Mac App Store, make sure your Mac supports MacOS Catalina. List of computers compatible with Catalina:

  • IMAC (2012 or later),
  • IMAC Pro (2017),
  • Mac Pro (2013 or later),
  • MacBook 12 inches (2015 or later),
  • MacBook Air (2012 or later),
  • MacBook Pro (2012 or later).
refit, installation, catalina

Some users have encountered problems when downloading and installing updating on Mac.

Errors “Network connection is lost” or “MacOS installation cannot be continued” with a poor or slow Internet connection, as well as if many users simultaneously load the OS. Use a faster Wi-Fi network or connect to the Internet using a cable. Reload the App Store or try to download the update a little later.

If everything is fine with the connection, check if there is enough space on the disk. The update weighs about 6 GB, while the installation and correct operation of MacOS Catalina will take from 15 to 20 GB. To find out how much space is left on your Mac, click on the menu line on the Apple icon about this mac storage. If the space is not enough, delete large unused files or transfer them to an external disk.

If the MacOS Catalina installer is partially loaded or damaged, find a file with the name Install MacOS 10 in the Finder appendix.15 and delete it. Download the update again.

If when loading the update, errors “exceeded the waiting for the gateway” or “gateway failure” appeared, load the Mac in safe mode, and then download and install the update. ICLOD can also help.

If the update is downloaded, but the installation master does not start, find the Install MacOS 10 file.15 in the Finder app and twice click on it to start the installation.

MacOS Catalina got stuck on the settings screen

After loading and installing the MacOS Catalina update, some poppies get stuck on the settings screen.

Forcibly reboot the Mac by pressing and holding the shutdown button for a few seconds. Wait a few seconds and press the power button again to enable Mac. Run the installation process MacOS Catalina.

I can’t go to MacOS Catalina

After installing the update of MacOS Catalina, some users could not log in under their profile. Also, many were faced with the problem of departure from the user profile to the input screen.

Reload Mac holding the Command (⌘) and S keys on the keyboard during boot. In the command line that appears, enter:

Then press the Enter key and enter the command:

This command deleys a damaged system file, so the entrance to the system will be like the first time. This method will help to enter MacOS Catalina running IMAC, Mac Pro or MacBook.

Bluetooth or Wi-Fi does not work at MacOS Catalina

If after the transition to MacOS Catalina you cannot turn on or off Bluetooth, as well as connect to Bluetooth devices, open Finder, in the upper menu, select the transition to the folder, enter

Delete COM file.Apple.Bluetooth.plist or move to another folder. Reboot the computer and try connecting to the device via Bluetooth.

If you cannot connect to the Internet via cable (Ethernet) or Wi-Fi, run the Mac in safe mode and check if the Internet works. If the Internet works in a safe mode, the problem with the browser or the expansion in the browser. Update the browser and extensions, set the last MacOS update.

The keyboard or mouse in MacOS Catalina does not work

If the keyboard does not work after updating MacOS Catalina, reboot the Mac. Close the MacBook cover for a few seconds, then open. The keyboard should earn.

If after installing MacOS Catalina the mouse does not work, open finder and go to the ~/Library/Preferences catalog/. Delete two files:

You can also move files to another folder (for example, download or desktop). Reload the Mac.

32-bit programs do not work in MacOS Catalina

Apple does not support 32-bit programs on computers with MacOS Catalina, and it is impossible to force them to work.

If you have not yet updated Mac to MacOS Catalina, check which 32-bit applications are installed on your computer.

refit, installation, catalina

Click in the menu line on the Apple logo about this MAC report on the software system. If in the list of programs in the extreme right column 64 bits (Intel) opposite the application is indicated “no”, then it will not work for MacOS Catalina.

Update the current program to the 64-bit version or find another.

Sidecar does not turn on in MacOS Catalina

Sidecar is a new Apple function presented at MacOS Catalina. Allows you to use iPad as a second monitor for Mac.

Make sure IPados has been installed on the iPad.

  • IMAC 27-inch (end of 2015 or new)
  • Mac mini (2018)
  • Mac Pro (2019)
  • MacBook (beginning of 2016 or newer)
  • MacBook Air (2018)
  • MacBook Pro (2016 or newer)

Bluetooth and Wi-Fi should be included on Mac and iPad. It is also necessary to enable the service transfer function on both devices. Mac and iPad should be connected to one Wi-Fi network so that the Sidecar function to work without problems.

If you have older iPad or Mac models, you can try to turn on Sidecar, but the result is unlikely to be satisfactory. You can also use third.party applications with similar functionality, such as Duet Display.

Inhibits Mac OS?. Catalina checks any unsigned code via the Internet when starting

Many users after switching to Catalina began to complain about the brakes. Western colleagues found out what is the reason: MacOS sends the hash of any unsigned code for Apple server. This creates serious delays in execution, which can be easily checked:

Why is this happening? Apple has long been using the Notarization mechanism-with its help, users can be sure that the program signed by the valid Developer.id does not contain malicious components. That is, in addition to the fact that the application is signed, Apple will also automatically check it for Malware elements. Interestingly, in the future, Apple generally plans to prohibit the launch of programs that have not been notarized. Quote:

Beginning in MacOS 10.fourteen.5, Software Signed with A New Developer ID Certificate and All New Or Updated Kernel Extensions Must Be Notarized to Run. Beginning in MacOS 10.15, All Software Built After June 1, 2019, and Distributed with Developer Id Must Be notarized.

Now, apparently, for the purpose of running.in, any new unsigned code that you launch is sent to the Aapl server. This is easy to check by launching any network analyzer and seeing an appeal to the API domain.Apple-Cloudkit.com. It should be noted that not the code itself is transmitted, but a hash-shumma. You can check this in two ways. compare the volume of data transmitted over the network for scripts of different sizes; and also looking at the contents of the demon himself responsible for sending data (Otool.Tv/usr/libexec/syspolicyd). Nevertheless, with a slow Internet connection, the delay can be seconds. the user from China writes about a delay of 5.47 seconds.

On the one hand, Apple can be understood. she takes care of users’ safety, however, at the same time turning the process of any development on their platform into hell.

But I want to quote the words of the developer, who was the first to pay attention to the problem: such behavior of the operating system indicates serious problems in its design, when two methods from a low.level system API (for example, Exec and Getxettr) perform synchronous network appeals before returning the result.

How to install macOS Catalina on PC (Complete Hackintosh Guide) v.2

Often, with the release of the new version of MacOS, Apple leaves some old Mac. And with the release of Catalina it happened: now the devices of 2012 are supported and new. At the same time, obviously, in terms of performance, some models of 2011 (for example, the same MacBook 15 “) are faster than simple MacBook with Core M processors without active cooling, so the destruction of support is definitely not related to the speed of old models.

And third.party developers confirmed this by creating a tool called DOSDUDE CATALINA PATCher, which allows you to unofficially install the latest version of MacOS for many unsupported Macs (the whole list is on the site). At the same time, it should be understood that some functions (for example, SideSar) may not earn money, and the system itself can be unstable or slow.

The instruction itself is not very complicated. To get started, download Patcher itself at the link above:

Click the right mouse button to the Catalina Patcher application and select the Open option, after which in the program itself twice click on the “Continue” button:

Click on the “Start download” button. The image itself weighs 7 GB, so its pumping will take some time:

After loading, connect a USB flash drive to your MAC, previously formatted at the Mac OS Extended (Joint). In the installation methods, select the “Create loaded installer” option:

Select your USB flash drive in the list and click on the Start button, then wait until the image flows into the flash drive.
