EFI issues: Option key does never start Startup Manager #91

Closed vitalz closed 4 years ago

vitalz commented 4 years ago

MacbookPro5,2

When Option key is pressed and/or held then Startup Manager will never start - even there is an external bootable disk attached via USB.

OS Patch manual also tells nothing about multi-boot abilities for any model: if this is possible, limited or impossible. There is also no manual for a case a user puts a second bootable disk in Data Doubler (yet: if that disk has Linux Mint it seems it will boot Mint always).

Also imagine a use case Data Doubler disk has El Captain MacOS with Windows 7 and the primary disk has Catalina patched installed: how is to switch between them?

Probably, EFI loader needs improvements.

P.S. NVRAM, PVRAM, SMC resets didn't resolve issues described.

Option key happens before anything the Catalina patcher can change. Reset NVRAM harder.

Try Option key of separate USB keyboard?

@joevt Isn't Terminal command in Recovery mode enough to reset NVRAM?

nvram -c

I noted that at first patched Catalina boot it set its disk into NVRAM like something permanent to boot (as I understood). Also I used external Apple USB keyboard: it didn't help anyhow.

I assume my Macbook might have broken and repaired NVRAM module, etc. but nobody has told me any indicators of that. On macrumors forum I met posts people had similar problem on the other mac models.

To reset nvram - hold Command-Option-P-R until it boots. Keep holding it until it does that a one more time. https://support.apple.com/en-ca/HT204063 https://support.apple.com/en-ca/HT201295

I don't know if nvram -c clears the same stuff.

I don't know of a way that makes Option key at startup stop working as it has in your case.
