I just bought a Powerbook G4 and have a few questions regarding software issues. I bought it mainly to edit with Final Cut, but am finding more and more that I may need to make this my main computer. From what I understand is that if a file ends with ".exe" it is a Windows application and does not run in mac. Does that mean if a piece of software for example Final Draft 6.0 works that with XP and Mac, if I installed it on a my PC first it will only run with a PC? I also have adobe photo shop that was loaded onto XP first and then when I try it with the mac only a ".exe" setup is there. Also my printer is a HP 656c, before I bought the mac I was told that any printer will work. So, I hooked the USB cord to the Mac without installing anything and it read there was printer, but unlike XP it wanted software. Though when I tried to load the software it only contains ".exe" setup. Does this mean I must buy new software so that it will work on my mac? Also for those with Office X, does a word document made on a PC transfer to a Mac and then back again? Thanks for reading my newbie questions!
