Hello, I’m posting about my failed attempts to upgrade to macOS Tahoe.
I managed to update once before, but I had to roll back, and now I can’t upgrade to Tahoe again no matter what I do.
I’ve customized my EFI multiple times, and it works perfectly with Sonoma, Sequoia, and even Ventura. But the moment I try to update to Tahoe, everything breaks. I tried using the OTA updater, which worked once, but now every time I download Sonoma and attempt to update, it crashes at the macOS installer stage and completely breaks my system. I’ve wasted a huge amount of internet quota trying to fix this.
I also tried using prebuilt EFIs from multiple YouTube guides, thinking the issue might be my EFI. On top of that, I tested the raw offline installer from Olarila and the Tahoe recovery image. None of them even open the installer — the system just keeps restarting before it can enter the installer.
At this point, I’m completely stuck.
