I still have my 5,1 w/64 gigs of RAM running Catalina with DosDude1's patch...I installed a Titan Ridge Thunderbolt card (which I had to flash first) and it runs pretty flawlessly up to ProTools 2022.10 and whatever version of Logic stopped on Catalina...
But I did move to a Mac Mini M1 in 2020 with on 8 gigs of RAM and it outperformed the 5,1 by nearly 15-20%...and once I made the shift to Native Silicone apps its even more stable.
I recently upgraded to a Mac Pro M2 14" laptop with 16 Gigs Ram and it outperforms the M1 by probably 10-15% (in non-scientific real world stuff).
I do miss the days of adding in your own hardware and drives and tweaking the machine...but these M-series appliance have some serious mojo under the hood, I have not regretted it except for Avid dragging their ass on Silicon Native compatibility, but in Rosetta everything runs fine.
I'm not really a big Logic guy, it doesn't ever feel professional to me, but it is a solid DAW in Silicone...and Dolby Atmos mostly...
My Atmos Suite works fine in rosetta though.
I did originally get an OWC dock, the apple "Let f the customer by not giving them ports" nonsense requires further investment...I have looked at the Sonnets because I have a few UAD PCIe2 cards that would be nice to not toss away...since I have about 80% of every UAD plugin...(I have recently added the Softube stuff particularly because I picked upa console 1 and I was pretty shocked at useful and quicker that device makes things...and it runs about 75% of my UAD plugins so win/win)
