Question before I do a SSD upgrade
I’m currently running Sierra 10.12.6, I need to take my laptop from 500 gig to a terabyte. I understand I have to upgrade to High Sierra 10.13 to get that EFI update, or whatever it is, to make the OWC Aura Pro X2 SSD work. Fine. My problem is that I have a program that I require that doesn’t yet work beyond Sierra that I am loathe to give up.
So how about this compromise. I keep pretty good backups, so I refresh my backup, which I would do anyway. Upgrade my laptop to 10.13, do the firmware update, everybody’s happy. I install the 1 TB OWC Aura Pro X2 SSD drive.
Can I then restore my 10.12.6 Time Machine backup? The new drive is blank at that point and will be asking for, among possible sources, a TM restore source. My firmware has been updated, it’s happy. Will the firmware let me run Sierra on the newer firmware, or am I at a risk of bricking my laptop?
Another possibility is to create a VM running a Sierra image for this one program under a pre-Catalina MacOS, I’m not averse to that. Catalina is not an option at this time as it breaks too many programs that I cannot live without and they would not fare well under virtualization.
Thanks for your suggestions!
