@hybridhavoc Please, for the sake of your mental health, get an SSD. A few months ago, I replaced the HDD on an old Mac Mini and paid only $15 for a 256GB SSD. The mf runs like it's new.
Oh no worries on that, I did. Luckily the drive I was replacing was just for media, not for the OS, but I decided to go with a 2.5” SATA drive for it. My OS drive and games drive were both already NVME M.2 drives.
Speaking of slow computers though, I recently reinstalled MacOS on an iMac from like 2012… It was excruciatingly slow, even just to boot into the OS. I do not miss those days.
Does it take a lot less time these days? The 2014 Mac Mini is the first and (so far) the only Apple device I've owned. The OS installation and updates take close to an hour on this one.
