If you do find a disc image, to burn it, you will need to make sure your burning software has an option that makes the disc bootable. Toast used to do this, not sure what exists out there these days.

I’m 95% certain it was snow leopard, because I remember making a special trip to comp usa to get it on release day. I didn’t do that for Lion. I might even have skipped that one entirely. I still have that snow leopard disc, somewhere

Got a M1 MB pro (the basic one) so I could write papers and do school work a few years ago. This year, I finally retired my big hackintosh rig for a M2 Max MB pro because I didn’t need a full size computer anymore and it was 10+ years old. Anyway, it’s kind of hard to tell the difference between the two. The M2 certainly does big tasks better, but my son uses the M1 all the time for music composition and it does a fabulous job. If you really need power, get the M2 pro or max, but only if you really need power. Otherwise an M1 will likely be fine. I read countless reviews and tests, and the M2 is supposedly 20%, but the extra GPU is what I went for because I needed 3 monitors (which is still not easy to get working), otherwise I would have saved the money and gone with an M1. Unless you need 3 monitors, then an M1 will be fine for the next 5 years.
