Description : macOS Catalina Patcher is an application that allows you to install and run macOS 10.15 on unsupported hardware. It was developed by Dosdude, who also developed similar fixes for Sierra, High Sierra, and Mojave.
If necessary, the program can download the latest version from Apple servers and create a bootable flash drive from it.
To create media with macOS Catalina, you need to specify where the installer is and select the media (at least 16 GB).
Media creation, installation, post-installationAttention! All screenshots from the previous distribution: macOS Mojave Patcher but the principle is the same. What you need:- A copy of the macOS Catalina installer application. This can be obtained on the Mac App Store using a machine that supports Mojave, or using the built-in tool download function. In the menu bar, simply select "Tools> Download macOS Catalina ..." - a USB drive with a minimum size of 16 GB. (I recorded and installed with 8 GB of media) - A copy of macOS Mojave Patcher in the Programs folder1. Insert the desired USB drive, open Disk Utility and format it as OS X Extended (Journaled). 2. Open the macOS Catalina Patcher tool and find your copy of the macOS Catalina installation application.
* Make sure the tool has successfully tested the application. 3. Then select the USB drive in the Target Volume list and click “Start Operation”. 4. At the end of the operation, load your target unsupported Mac from the USB drive that you just created by holding down the Option key while turning on the device and selecting the USB flash drive with the installer. Note. Follow steps 5 and 6 only if you intend to perform a clean installation. Otherwise, you can simply skip these steps and install on your volume associated with the previous version of OS X, and it will be installed with all the previous information, settings and programs saved.
5. When the installer boots up, open the “Disk Utility” in the “Utilities” menu or double-click it in the “Utilities” window in the lower left corner of the screen. 6. Select the drive or partition you want to install on and remove it to use either Mac OS Extended (Journaled) or APFS as the type of file system. When formatting the entire disk, make sure that the GUID is selected. - Using APFS on later 2009 and later machines will work only with High Sierra. - It is recommended that you use APFS only if the destination drive is an SSD.
- If you have a machine that does NOT natively support High Sierra (and therefore cannot load APFS volumes initially), pay attention to the following:
- If you use APFS, you will not have a bootable recovery partition.
- If you decide to use APFS, the custom boot method will be installed by the tool after installation, since the firmware for these unsupported machines does not support booting from APFS volumes. 7. Install macOS on the required volume. 8. When installation is complete, reboot back from the installer flash drive. This time open the macOS Post Install application. 9. In the application, select the Mac model that you are using. The optimal patches will be selected for you based on your chosen model. You can also select other corrections of your choice.
10. Select the volume you just installed macOS Catalina on and click Patch. When he finishes the correction, click "Reboot." This can take up to several minutes, restoring caches before rebooting.
- If for some reason the system does not work correctly after a reboot, boot back to the installer flash drive, run the patch again after installation, and select “Force Cache Rebuild” before rebooting. In most cases this is not necessary. 11. After rebooting, you will be taken to a fully working copy of macOS Catalina.
- If you selected the macOS Post Install tool, your Catalina program will have a program called “Update patches” located in the / Applications / Utilities folder. This program will notify you when new patch updates are available for your computer and prompt you to install them. If you do not have Patch Updater installed, but you need it, you can download and run the script found here.
