Hey,
first: I love OCLP. Got Sequoia running on my 2013 MBPr. Now I wanted to parallel-boot Linux MINT.
What I did was partition the drive 50/50, install Linux MINT on the 2nd half but with "other" method, writing the boot loader onto that separate linux partition.
Then I see both OS in OCLP bootpicker. I can also still start macOS... until I start and shutdown Linux once => Then I get three entries in bootpicker: "EFI", "Linux", "macOS" but macOS only leads to an Apple symbol with no further progress.
I was able to fix it by booting from OCLP USB stick and reinstalling OCLP onto the internal drive, also tried the "Method A" from Dortania with the additional OpenLinuxBoot.efi and the driver for ex4, then I always only get two boot entries - but the misery repeated when I then booted into Linux. After that when trying to boot macOS, I only get the apple but no progress bar.
Interestingly I can always still boot and recover the situation with the OCLP USB stick, so it seems to be some EFI partition related issue rather than NVRAM, maybe?
Any ideas?
Thanks a ton! :)
Cheers!
