I have just re-made the Catalina installer, with the updated OS. It could not install from it, like it could not copy. Then I have tried to reinstall Mojave, it worked pretty cleary last year the exact pen drive. It failed as well, saying something like: not package found, contact the system administrator. I was able to boot from USB pen drive Linux and install Windows from DVD. But no macOS from the pen drive, even from what worked fine before. I have reseted the BIOS several times, no succes. The first sign of something wrong was this: When I first tried to boot Catalina, it said something about BIOS (BIOS, not UEFI) reset and enter setup. I hapenned several times on my attempts. If something screwed in my hardware? The USB ports? The BIOS perhaps?
Me (and many other people) experience eye-ache from new Macbooks (and windows machines).
I have spent two years of trial-and-error and found that installing macOS Mavericks on my MacBook (pro 13 late 2013, Intel Iris 1536 MB) resolves the issue of eye ache completely. (it is believed that newer systems use harsher version of temporal dithering that causes of a certain group of indivisuals eye aches).
I cannot stay at Mavericks because of software support and security issues, so the only thing is an issue now:
How can I take drivers from Mavericks and install them on Catalina? (I tried replacing .kext in /System/Library/Extensions with old files but it didn't work).
I have a Vanilla Catalina issue….with a different twist. Installation/upgrade went fine, just took a loooooooong time as I was working from a cloned Mojave external USB hard drive. Boots just fine, and all my apps seem happy. Here lies the twist....Sleep/wake. It will sleep and stay asleep just fine. The issue is with waking up:
Under Clover with FakeSMC, it would wake, but not accept my password. ?????? Ok, its clover....
Under Clover 0.5.5 with VitrualSMC, it would wake, but with no video signal/crash. Again, its clover...
Under OpenCore 0.5.5 with VirtualSMC, it would wake, but with no video signal/crash, and no crash log.
Under OpenCore 0.5.5 with FakeSMC, it sleeps, it wakes,....and accepts my password!!!! Only once. The next time it went to sleep, it would wake, but not accept my password. HUH??????
Kinda strange. For the most part I have just stuck with Mojave. I was waiting for the next build of OC, but I may just use OC builder myself and see if the latest solves any issue, as I see there have been quite a few updates to the project. In the mean time…..suggestions? I have attached an image of the efi.
