Yes!
The M1 Mac Mini is an amazing machine for the price.
Think of it this way, a year ago, the M1 Mac Mini had the highest single-core performance of any Mac ever, and it was probably the cheapest Mac that ever existed when adjusting for inflation.
I have a few complaints about it, but nothing major.
One complaint was the lack of multi-core performance increase over my Late 2012 iMac with the 3rd Gen i7. While the M1 was faster, I expected better results when SW encoding over my much older iMac.
When doing long encodes, the M1 was only 50% faster than the 3rd Gen i7 in my Late 2012 iMac.
Really, the only other issue I have with the M1 MM is sometimes it Safari chokes when opening up a new tab for some reason. This has been going on since I have been using my M1 MM, so about 9 months.
What OS version are you using? Could it be related to the memory bleed issue?
The reason I ask is because I have pushed the M1 Mac mini to its limits when testing and comparing it to my older Macs, and never seen a memory warning.
