I can address the remaining concerns separately, but wanted to make a quick comment here:
- Because you have two EFI partitions, one with old version of OpenCore and one with the new version, press F12 key repeatedly when booting the computer.
So this morning I went to do as you stated, and I notice that in the boot picker it says OC Release 082 with the date.
I fear that somewhere along the lines I might have moved the new EFI into the Catalina one by mistake. This may explain why when I compared a backup version with the one I opened to check that they appear differently.
I thought I was careful but clearly not careful enough.
- This will open the BIOS boot menu (not OpenCore boot menu).
- To boot Catalina, select the disk containing the Catalina EFI partition.
- Now old version of OpenCore boot picker should appear.
- Select the Catalina disk and log in.
I only have the Catalina disk available as I removed the MacOS Monty drive
- Check if Apollo and Apogee are working.
I am able to get them working in Catalina. However, when I am in Monterey, only the Apollo will fire up. I do also have a Chord Mojo 2 headphone amp. When in Catalina this connects using the USB-C connector and works, but when in Monterey it is not recognised, there are no drivers for this as it is class compliant.
** edit update**
Using my backup bootable drive, I have managed to fix the OC issue in Catalina and now I’m back where I started.
Now going back to Monterey, I’m still having issues with it recognising the Apogee. Looking at the information on home page, is only one USB-C/ Tb port available? The reason why I say this, the Apollo fires up, but not Apogee. I also have a Chord Mojo2 with USB-C port. In Catalina it recognises this straight away, but in Monterey it doesn’t see it. Is this an OS issue or USB ports in the OC build?
I may go for Big Sur if it is a more stable option? I was hoping Monterey was a little more down the line with this.
