Hey, New to the forum, first post Just order the new Mac Mini base model. My first Mac! Debated for a while whether to go that extra mile and get an iMac or MacBook. Didnt want to spend too much initially so left me with Mini or iMac. Already have a 24" Samsung monitor so decided to go with the Mini. Back to the question! I've order the base mini and I am going to upgrade the RAM myself. My questions are : 1. Is it 1x1GB stick (as it says on apple) or 2x512 sticks (as on Amazon)? 2. Is it ok to use mixed memory. i.e. If I buy a 2GB stick and theres 1 in it, use both giving 3GB or would it be better off to use 2x1's or 2x2's (same brand)? Thanks.
