Ok. I just got this mac, and i formatted the drive. It is formated to Mac OS Extended (journaled) Im trying to install Yahoo messenger. (it is doing this with all other programs im trying; limewire, thunderbird, opera.) I keep getting the message "The item "Yahoo! Messenger" cannot be copied because there is not enough space." It also says this when i try to pull a file off an 8 GB ScanDisk Flash Drive. Can anyone give me an idea of what to do. I dont have the OS disk. I loaded it using a friends, and now it is not letting me.
