Just a note - Used OCLP to upgrade my mid 2012 Mac Pro to Big Sur. While it took a bit of time and a couple of manual re-boots all went fairly seamlessly. However the 'upgrade' changed all of the permissions with attached HD's - internal and external. So took a bit of time to reset. For some unknown reason I lost the last 3 weeks worth of Time Machine BU's. OTOH I did get a 'graphic' asking if I wanted a 'tour' of my NEW MAC PRO. That had me smiling for the rest of the day.
Got a tip for us?

thats why your supposed to pull out any unessasary hardware when installing...bare minimum, and after its installed re-insert it all
I did - only drive in the unit was my 1TB SSD boot drive. And I had back up the system, using 10.13.6 just prior to running Open Core. Not a big deal, just curious. As I said, after the installation of Big Sur, all the reinserted and external drives had permissions altered. Was not consistent, however. On the + side, installation of Big Sur did solve a major problem with my VPN software. That alone was well worth the time spent. Going to run it like this for a while and go to Sonoma later.
