Mac Os High Sierra Patcher Tool For Unsupported Macs
DOWNLOAD ->>> https://fancli.com/2t7CrW
DosDude Catalina Patcher is a popular third-party tool that allows users to patch the MacOS Catalina installer on otherwise unsupported Macs. Of course, just because you can do this, doesn't mean you should, as there's a good chance that performance will be sub-optimal, while Catalina features may depend on modern Mac hardware (Sidecar, for example) and likely won't work at all.
Because of Final Cut Pro X 10.4.1 I needed high sierra. So I just did it. There was a problem with the graphics card (macOS graphic drivers where not recognizing the card and I had to use NVIDIA driver).
macOS Patcher is a series of software tools by Collin Mistr that allows versions of macOS 10.12 through 10.15 to be installed on unsupported Macs. In some cases, a GPU upgrade is advised for proper support of graphics acceleration.
Things you'll need: - A copy of the macOS High Sierra Installer App. This can be obtained from the Mac App Store using a machine that supports High Sierra, or by using the built-in downloading feature of the tool. In the Menu Bar, simply select "Tools > Download macOS High Sierra..."- A USB drive that's at least 8 GB in size - A copy of the tool - Download here (Current version: 2.7.0, SHA1: 73f180d30200ef5f6d900440fe57b9c7d22bd6bf) -- View changelog and download older versions here Known issues:- Trackpad (MacBook5,2 affected only). The trackpad in the MacBook5,2 isn't fully supported in High Sierra. While it works and is fully usable, High Sierra detects it as just a standard mouse, preventing you from changing some trackpad-oriented settings.How to use: 1. Insert your desired USB drive, open Disk Utility, and format it as OS X Extended (Journaled).2. Open the "macOS High Sierra Patcher" tool, and browse for your copy of the macOS High Sierra Installer App.*Ensure that the tool successfully verifies the app.3. Next, select your USB drive in the Target Volume list, and click "Start Operation."4. When the operation completes, boot your target unsupported Mac off the USB drive you just created by holding down the Option key while turning on the machine, and selecting the drive.Note: Only perform steps 5 and 6 if you intend to do a clean install. Otherwise, you can simply skip these steps and install to your volume containg a previous version of OS X, and it'll do an in-place upgrade.5. When the installer boots, open Disk Utility from the Utilities menu, or by double-clicking it in the Utilities window on the bottom left corner of the screen.6. Select the disk or partition you want to install on, and erase it, ensuring to use either Mac OS Extended (Journaled), or APFS as the filesystem type. If formatting an entire drive, ensure GUID is selected.-- Please note that if you use APFS, you will not have a bootable Recovery partition.-- It is recommended that you only use APFS if the target drive is an SSD.-- If you decide to use APFS, a custom booting method will be installed by the post-install tool, as the firmware of these unsupported machines does not natively support booting from APFS volumes. It is not quite as clean as native booting, but will not cause any issues while running High Sierra. A demo of the modified booting process can be viewed here.7. Install macOS normally onto the desired volume.8. When the install completes, reboot back onto the installer drive. This time, open the "macOS Post Install" application.9. In the application, select the Mac model you are using. The optimal patches will be selected for you based on the model you select. You can also select other patches of your choosing.-- The "i" button next to each patch will show more details about the respective patch.10. Select the volume you have just installed macOS High Sierra on, and click "Patch." When it finishes patching, click "Reboot". It may sit there for a few moments rebuilding caches before rebooting. -- If for some reason the system fails to work correctly after rebooting, boot back into your installer drive, run the post install patch again, and select "Force Cache Rebuild" before rebooting. This isn't necessary under most circumstances.11. When it reboots, it should now boot into a fully working copy of macOS High Sierra.Additional Info:- If selected in the macOS Post Install tool, your High Sierra install will have a program named "Patch Updater" located in your /Applications/Utilities folder. This program will alert you when new updates to patches are available for your machine, and will prompt you to install them. If you do not have Patch Updater installed, but would like it, you can download and run the script found here to do so. 2b1af7f3a8
