I just found out that maybe...just maybe...the job training I'm going to can help purchase the adobe suite for me. I have a Macbook running leopard with one gig ram ( I may get help with upgrading ram too.) However I don't have a system disc as I bought it refurbished. I've been reading rumors about adobe not playing well with mac lately and wondered if anyone could point me at the right system disc to find. Does Snow Leopard work with Adobe? If so I may as well just go for an upgrade. If not, I'll have to hunt down the older system disc. Right now I have NO system backup-I can't afford another external hard drive, or reformat what I have for time machine, since it's half full of stuff off the old imac (and old imac is still using it too). I wouldn't even know where to start trying to move all that stuff. Anyway the system disc would let me set up a firmware password and make life difficult for thieves. So-what do I need to look out for if I go for this?
