i have a imac8,1-mac os x 10.5.8, 2.4 HGz Intel Core 2 Duo, 2GB 800 MHz ddr2 sdram-well, first of all this has been the best Computer I have ever owned! I downloaded a cam video using "Vuze" several months ago, and thats were my problems have started! its been getting worst, and now I cant even use it! freezes all the time, spinning circle everytime I try to do anything or just touch my mouse & slow!! anytime I plug an external hard drive in, it states its been corrupt! FYI- Vuze has been a great program for me, but I got greedy & stupid, and downloaded some cam movies! ive used the program since 2008!----------------heres the info on my original mac i wrote about-ibook G4, 10.4.11, 1.33 GHz powerpc G4, 1GB DDR SDRAM, powerbook 6,7--at this point, Im not going to update the powerbook with 10.5, as it would be cheaper to get a newer(used)labtop! is it easy to download an earlier version of itunes for it?......if you could help me with my main Mac that I wrote about at the top would be great! ive been trying to remove my pics from iphoto, but its been difficult, as it stops & freezes! hoping to do a system reboot! thank again!!
