Need help building an OpenCore Legacy Patcher EFI for iMac18,2 (macOS Tahoe)
Hey everyone,
I've been trying to get macOS Tahoe running on my 2017 21.5" iMac (iMac18,2), but I've been stuck for days because my OpenCore EFI doesn't boot correctly.
My hardware:
Model: iMac18,2
CPU: Intel Core i5-7500 (Kaby Lake)
GPU: Radeon Pro 560 (4 GB Polaris)
RAM: 8 GB
My internal Tahoe installation is already there. I just need a working OpenCore EFI that can boot it.
I've tried:
OCLP 3.0.0 nightly
OCLP 2.4.1
Manually copying the generated EFI
Creating BOOTx64.efi manually
Building on both macOS and Windows
The EFI is detected by the iMac, but it either goes to a permanent black screen or kernel panics.
Would someone with a similar iMac18,2 or experience with Tahoe + OCLP 3.0.0 be willing to build an EFI for me or share a working one?
If any additional information (serials, logs, config.plist, etc.) is needed, I'm happy to provide it.
I'd really appreciate any help. This machine has become my personal boss fight 😭. Thanks!
