I sat, contemplating that this past week, with the parts of my Mac mini arrayed on a table before me, like a field-stripped rifle. In the midst of adding new RAM and an additional drive to the mini, I found myself remembering a few of my favorite easily upgradeable Macs of yesteryear.
Ah, the memories. Dan Moren writes about the good old days when you could open up a Mac and replace a part. I remember well digging inside old Macs, from the LC 475 to the Performa 6200, to the easy-to-open cheese-grater Mac Pro. The last time I opened up a Mac was back in 2010, when I installed a hybrid drive in a 2009 Mac mini.
I guess I miss this a bit, but things are so small these days that it’s just too hard to not make a mistake.
