MP 1,1-5,1 My MacPro5,1 has strange problem

[yuta2021]

Hello there,

my MacPro5,1 installed Catalina & BigSur (with Catalina Patcher&Patched Sur)

after that I changed SataSSD(HighSierra inside) can not open system.

But from Recovery mode - command+Q - chose drive - reboot - I can into HighSierra system.

next normal reboot (from apple icon) can not. very strange problem.
Youtube short movie (you can fast forward video)

Can anyone solve this problem?

Thanks!

So a few questions to help us help you troubleshoot -

1. Are you booting with the option key to get the boot picker and then choose your OS? If you do that can you boot into High Sierra?
2. Are Catalina and Big Sur on another drive(s) - that is not on the same drive as High Sierra? If so remove the Catalina/Big Sur drive(s) and try and boot. Does that work?
3. Have you ever been able to boot Catalina and Big Sur? That is it has been working and now just stopped? It might be helpful to describe your steps. Did you install Catalina and have that working and later install Big Sur and then it broke?
4. How about posting a diskutil list - let us see how your OSs are installed on the various drives. I am assuming you only have a High Sierra recovery partition?
5. Since you said patched Catalina and patched Big Sur you are not using OpenCore - correct?

Hi, Sfalatko. Thanks your question.

1: If I use option key and choose High sierra, can not boot into High Sierra.

2: I have three SATA SSD 840PRO. one SSD drive have one OS.
I only use one drive on the slot and test booting.

3: Yes,Catalina and Big Sur drive working very well.
Yes,first I use Catalina Patcher installed Catalina, next on the Catalina system use
Patched Sur installed BigSur OS.
After that I removed BigSur drive from slot, and changed High Sierra SSD Drive.
can not into system,(only from recovery mode choose reboot, I don’t know why )

4: OK I post diskutil screen shot. BigSur drive already deleted.(I hate him)

5: Yes, Not use Open Core.

I think Catalina or Big Sur Patch changed Hardware’s firmware.

But if I use USB High Sierra install disk install clean OS. I can into system.

Unfortunately I don't have any answers as to why with only a drive with High Sierra won't boot into the OS but will boot into recovery. You may have to reinstall High Sierra. I guess you could try and bless the High Sierra disk but I can't see why that would be necessary.

For diskutil I meant open a terminal window and then enter "diskutil list" at the command prompt and post the output here.

And to summarize - with just Catalina drive installed you can boot into Catalina, with just Big Sur drive installed you can boot into Big Sur, but with High Sierra drive installed you cannot boot into High Sierra (you just get the circle with diagonal line). If all that is true I would reinstall High Sierra on the High Sierra disk.
