Answer to: Can I upgrade the memory to 16 GB? (DIY)Yes you can. OWC just posted ram upgrades for these models (non-retina). I purchased 16GB and I can't wait for it to get here. Don't buy ram from Apple unless you're rich. OWC has reasonable prices and they test the machines and certify that these ram increases should work without a flaw. Taking the Mac Book Pro is very simple and it will only take you around 10 minutes; in addition they have DIY videos. Just follow the 2011 MacBook pro video instructions, since the 2012 construction is basically the same. Best regards, Jose
Answer to: Max Ram In MacBook Pro mid 2012I just purchased RAM from OWC, 16 GB for my new MacBook Pro non-retina display. It should run great, these folks from OWC know their stuff. I've never had any problems with their recommendations. I installed more RAM on a previous MacBook Pro 2007 model which came with just 2GB and I raised it to 4GB and can still raise it up to 6GB if I wanted. But since I now have this new model, 16GB should make it run like a charm. Best regards, Jose
Answer to: HDD sluggish, fixing permissions does not work.Try the beta software CCleaner for Mac. Makes repairing permissions a breeze and it's been working nice so far. I have an A1226 machine (2007 Santa Rosa Mac Book Pro). I had to replace my hard drive once since it was damaged by a drop and made funny sounds. But give CCleaner for Mac a try.
