i did an archive and install (after doing a full back up of my tiger) and everything seems to have gone fine its a teeny bit sluggish but i guess this is just to do with spotlight indexing things and other stuff so it'll buff itself out eventually. probably the reason why this transfer is going so slow as well. anyway questions 1) i read that not all things get migrated after the install, what files should i be making sure have been transfered from the previous system to the new? 2)how much space do i need for time machine? 3)my parallels wont work because it cant find a driver... best bet is to reinstall, however i dont know what my serial key is, anyway i can find it? or will it not ask me for it? 4) anything else i should be watching out for? oh and with spaces, how would i, for instance, get programs like Adium and my Day (from MS Entourage) to follow me round to each space?
