How to Fix the Apple.com/Mac/Startup Error on iMac14,1
The Apple startup support screen usually means the Mac could not find a valid boot path, the installer is wrong, or OpenCore was not installed correctly.
Step-by-Step Fix:
- Use a supported path: From Yosemite, upgrade first to a newer Apple-supported macOS if possible before using OCLP.
- Build OpenCore for iMac14,1: In OCLP, choose the exact model and install OpenCore to the target disk EFI.
- Boot from the OpenCore picker: Hold Option at startup, choose EFI Boot, then select the Monterey installer.
- Install Monterey: Let the installer reboot several times and always return through EFI Boot when needed.
- Apply root patches: After the desktop loads, run Post-Install Root Patch for graphics and legacy hardware support.
Original Question: "Support Apple.com / Mac / startup"
 | I’m trying to upgrade the os on a IMac 14.1 that’s running on Nividia and I was following a video tutorial and it gave me this error. I was upgrading to Montreay so does this mean I have to upgrade to something slightly older? I was upgrading from Yosemite. I’m a little confused and if anyone could help I’d greatly appreciate it! If you can explain it like I’m 5 years old because I’m not very good at ANY of this! [link] [comments] |
