marvelloard 25 Posted November 6, 2020 Posted November 6, 2020 (edited) I recently switched to OpenCore 0.6.3, and it works almost perfectly fine. Sometimes at boot, however, the 2nd loading bar (which leads to the desktop) gets stuck and the desktop never appears. Since the HDD LED blinks a lot I know it's doing something. Can you help me to make it boot reliably? EFI.zip Edited November 9, 2020 by marvelloard typo fix Share this post Link to post Share on other sites

Edit: It appears that a defective SATA cable or port on the HDD (not even boot drive) caused the issue. It didn't happen again since I swapped cables and ports yet. I will keep an eye on that though. Edit2: The freezes started happening again, even more often. It wasn't a hardware failure. Ultimately, I started from scratch setting up OpenCore again, and I was very careful about ACPI. The issue now is completely gone. :-) Even updated to Big Sur, no problem! Edited November 22, 2020 by marvelloard solution found! Share this post Link to post Share on other sites
