I’ve been managing to keep an ageing 2012 Mac Pro as my main computer for nearly 7 years now, and from time to time its really been a struggle. Over the years I’ve added various upgrades and replacement parts, and its somehow managed to keep going, despite getting a tremendous amount of use. Lately though it’s been driving me mad. It takes nearly an hour to reboot - from off to being useable. The OS comes up in about two minutes, but by the time everything loads and settles down and is useable - it’s nearly an hour. This is partly because of a slow system drive, and partly due to years of bits and pieces clogging the OS

I knew something wasn't right. My computer, a 2012 Mac Pro, had suddenly decided to go slow. Not just slow, but slow in a very specific way. It was like it was stopping to think every few seconds. It was something that was eerily familiar. I'd seen this before, and I hoped the cause wasn't the same, but I knew in my heart what was happening. My hard drive was failing. Worse, it was my system drive.
