I have Big Sur 11.6.1 running on my 2012 iMac via OCLP. I want to upgrade to Monterey. Is it as simple as : Build OCLP using latest version released today. Patch system disk with latest OCLP including files needed for Monterey ,Run Monterey installer ?? I've created a Monterey USB installer, but can't get it to boot. Given I have an already patched system, can I simply run the official Monterey installer from /Applications? Everything is also backed up.

The way I remember doing it when I had Catalina installed on my Late 2013 rMBP: Download OCLP TUI offline 1 - select Build OpenCore 2 - select #2 Install OpenCore to USB/internal drive 3 - navigate to install to internal drive 4 - reboot, select your boot drive from picker 5 - when desktop reloads, check System Preferences / Software Update, the Monterey full install choice should available 6 - download and run the darn Monterey installer 7 - reboot you got Monterey If ya want more detail, maybe ya might wanna go ask in MacRumors Forums? Basically OCLP replaces some of your BootROM code and fools your machine through some technical chicanery into thinking it CAN run Monterey. You'll know OCLP is doing its job after step 4 and you get a cutesy hard drive icon picker at boot. I was using earlier versions of OpenCore to give myself a boot picker on my Mac Pro 5,1 and some other coolness like being able to run Netflix and other HTML5 based video pages in Safari (which you normally can't do on an unpatched 5,1 even with a recommended video card) Also: https://dortania.github.io/OpenCore-Legacy-Patcher/START.html Binary Badger fucked around with this message at 03:31 on Oct 27, 2021 |
