hi all, so last year, i gave my dad my macbook pro... i wiped it clean, signed him in with his ID, added some pics to iphoto and music to itunes. simple, right? later, he took it to a computer tech to get help transferring over old files from his dell. my dad's computer illiterate and probably misled the techs... they created a second user account, and added my apple ID in addition to his. it really messed everything up, as now, the app store wants to update iphoto for BOTH apple IDs (didn't know that was even possible). additionally, all his music is on one account and not the other, and one account has some iphoto pics, and the other account has different iphoto pics. it's a mess. and i don't want my apple ID on his computer... so what do i do? it seems easiest to wipe it clean and start over, but i'm worried about losing some files - especially figuring out how to combine the two iphoto libraries. thoughts?
