I bought a Mac mini last week to use as a work computer--now that I've got some income I'm finally appreciating the idea of a "work expense". I didn't spring for the RAM upgrade since I felt pretty ripped off after doing that for the MacBook.
Apple only sells them with 2GB of RAM but I'd read that you could upgrade them to 3GB. I figured what the fuck I'll just buy the 4GB and stick it all in and see what happens. Well the good news is that--as you can see from the screen shot--it'll use all 4GB.
If you do try to do the home upgrade read through this RAM upgrade walk through but skip their advice for getting the case off and watch this video instead. It has a much better technique that resulted in zero scratches. Be really careful putting it back together though, I tried to rush that and bent some of the tabs in the back so it doesn't seat quite right now.
I spent an hour or so working my way through the school's bureaucracy to figure out how to apply to graduate. Met my CS Adviser... that I didn't know I had. I hadn't taken CS161 (Into to programming) and he helped me figure out how to get that waived. Once that was settled they pointed me in the right direction and I put in my papers to graduate at the end of the Spring term. Just need to finish up this term and then get my thesis taken care of and I'll finally be a college graduate.
