2TB Hard Drive macOS Sonoma Ventura Monterey Preload PnP for Mac Pro 3,1 GTX760

2TB 3.5” Hard Drive macOS Sonoma Ventura Monterey BigSur Preload PnP for Mac Pro 3,1 GTX760 This is a preloaded macOS Sonoma/Monterey/Ventura/BigSur (choose 1 or 2 of them) hard drive for your updated old Apple Mac Pro 3,1 Tower computer. Sonoma/Monterey/Ventura/BigSur are the new generation macOS vs 10.X for your old Mac Pro, and there are many unexpected issues when trying to install it directly on your Mac Pro via Opencore-Patcher. After extensive testing, here is the best way to save time and make your installation almost plug-and-play. Installation steps A: (for GeForce GTX 760 2GB display card or most Apple supported GPU card) 1. Ensure your Mac Pro hardware (CPU, RAM, and Firmware) is ready for installation. 2. Plug in this hard drive into the first bay and keep the other bays empty. 3. Power on with PRAM. (PRAM reset: Shut down your Mac, then turn it on and immediately press and hold these four keys together: Option, Command, P, and R until the second sound) 4. After macOS starts, enter Admin’s password “password”, go to Finder/Applications, run OpenCore-Patcher, build and install OpenCore to the PnP hard drive (disk0s1), then ignore the reboot prompts and run start root patching from the post-installation menu. 5. After completing the above steps, restart again. 6. Click “About the Mac,” check the graphics information and test the smoothness of mouse movement. If everything is okay, you are done. 7. If the mouse doesn’t work smoothly, or the graphics information are incorrect, download KDK for the appropriate version. Then run revert root patch, and reinstall the root patch again, then restart once more; normally, the issue will be resolved. Installation steps B: For other GPU cards or CPU models, please at first try 1-4 steps of the installation A, if macOS starts failure/black screen, go to installation steps B) 1. Leave the old working macOS hard drive in the bay and remove the other hard drives. 2. Power on with PRAM. (PRAM reset: Shut down your Mac, then turn it on and immediately press and hold these four keys together: Option, Command, P, and R until the second sound) 3. Download lastest version OpenCore Patcher online (do not run it, just download). (https://github.com/dortania/OpenCore-Legacy-Patcher/releases/download/1.3.0/OpenCore-Patcher-GUI.app.zip) 4. Shut down, then plug in this PnP hard drive into another bay. 5. Power on as usual (without PRAM), run OpenCore-Patcher you downloaded on your old macOS, build and install OpenCore to this PnP hard drive (DO NOT MAKE A MISTAKE). 6. Shut down, then remove all hard drives, and then replug in the PnP hard drive into the appropriate bay (Bay 1 suggested). 7. Power on with PRAM, the PnP hard drive will boot and new macOS starts, enter Admin’s password “password”, go to Finder/Applications, run OpenCore-Patcher, install the root patching from the post-installation menu. 8. After completing the above steps, restart again. 9. Click “About the Mac,” check the graphics information and test the smoothness of mouse movement. If everything is okay, you are done. 10. If the mouse doesn’t work smoothly or the graphics information shows incorrectly, download opencore KdkSupportPkg for the appropriate version (https://github.com/dortania/KdkSupportPkg/releases), install KdkSupportPkg, run revert root patch, reinstall opencore root patch again, restart a few times; normally, the issues will be resolved. * Most unexpected problems are due to improper driver configuration; the last way to resolve all of them by yourself is via Apple security updates, simple and easy way but need 1-2 hours, so a lower version PnP hard drive is recommended. ** The password for Admin is “password”.
