This was a much needed upgrade for me. I've been using a mid 2011 Mac Mini server model for a couple years and while still great, it's going on 10 years old now. In terms of performance, as expected the new M1 Mac Mini is a fantastic upgrade.Everything has been fairly smooth so far, with only a couple hiccups that I had to resolve. First, it would seem that having wifi enabled was causing interference with my bluetooth connections. This was fairly inconsequential as I'm using an ethernet connection for online so I simply disabled wifi and the problem was resolved.Second, I could not watch any Amazon Prime videos and kept getting an error. Long story short, you need to enable Rosetta on your Mac Mini. It's a software that converts Intel based applications to run on the new Apple chip. Well, at least that's my understanding of it. I had to do a little digging on the internet but apparently you're typically asked if you want to install Rosetta but this isn't what happened for me. I had to figure out how to do it manually and luckily found a post online that explained it. Granted, this was using the Chrome browser. If you use Safari then you won't have to worry about it as movie playback on Safari worked regardless.Other than that everything has been fantastic. I paired this up with an external 2TB SSD for more storage and am also now able to sync up my iPhone 11 with this new Mac. So glad I upgraded and for the price I'm simply blown away. For years now I've figured that if I wanted a top performance Mac Mini I was going to have to shell out $1000+ but it looks like things have changed and I couldn't be happier.
