I’m currently using a Mac mini late 2012 with 2.3 GHz Quad-Core Intel Core i7, the OS is Monterey 12.7.
Not asking for any updates and the disk space is fine. Yes, I’ve tried running Photolab separately and makes no difference Mike tbh. I don’t have any other Apple gear sadly so snookerd there.
Deep prime seems to be too much for the PC to cope with, Prme is a little better but still slow.
I have the same situation - for Mac computers with an “Intel” chip, the more you want to process the image, the longer it takes. Deep Prime takes more time than Prime. But for now, just go ahead and do what you want, and eventually the slow Intel CPU will get you what you want.
I’ve got a Mac mini, 2018, with lots of good stuff installed.
My MacBook Pro with the Apple chip is light-years faster.
B&H has lots of used Mac computers at reasonable prices. You can try to find one with an M1, M2, or M3 chip. M2 is almost as fast, but will save you money.
As soon as I replace my Mac mini with one that has the Apple chip, I’ll be selling my old one, but that wouldn’t help you - you need the Apple Chip - or, you can buy a “graphics processor” for perhaps $500 to add to your own mini, but I’d recommend you get something with the Apple Chip built in.
