Re: [Avid-L2] Odd behavior in Mac OS Sonoma 14.0 trying to setup multiple StartUp Drives?

Only APFS boot volumes are supported on these.

Playing around on my new macstudio and I originally Carbon Copy Clones the initial startup to an HFS+ spinning hard drive.  I've done this before with APFS startup drives.  Today I partioned the internal Startup drive into two and Carbon Copy Cloned the initial CCC BU onto the newly created partition.  I tried both adding a partion and adding a volume to the group.  Unfortunately when I CCC'd back from the BU the macstudio doesn't see the new partion as a startup drive.  I've also got my spinning hard drive BU's mounted to the rear usb 3 port and they aren't seen as viable startup drives.  I did the hold down power button on startup but no matter what I do I can't get the macstudio to see anything other than the original internal startup drive.  This use to work on my 10.14.6 and earlier systems and I checked and I have the latest version of CCC. 

What am I missing in my CCC BU process.  Could it be because I'm CCCing to non APFS volumes?  That didn't stop things from working in my past.  Is there a secret handshake to get a second startup partion in Sonoma and maybe some of the other new Mac OSs?
