And even if you free up a bunch of hard drive space, I wouldn't expect that to help unless you defragment the hard drive also, using something like Norton SpeedDisk or Plus Optimizer from Alsoft. See: How To Deal With Common OS X Problems http://www.macattorney.com/tutorial.html Item # 12 >Also, how large a hard drive can I install in my computer? You can install any IDE (that is, parallel/ATA) 3.5-inch drive. However, your iMac can only access up to 128GB, so there is no point in paying for a drive that is larger than that. >Any other suggestions? Ximeta now makes external hard drives that can connect via the Ethernet port that your iMac has, though they are more expensive than internal or FireWire drives. This sort of drive should also allow you to access all of the capacity of the drive: <http://www.ximeta.com/products/netdisk.html> <http://www.outpost.com/entry?site=op:mfe040130&sku=3945658> Randy B.
