I have recently bought an iBook G4 as I was after an Apple on a budget, however, it is running Mac OS X 10.5. It has been running absolutely perfectly for just over a month, but suddenly seems to have hit a brick wall and is running incredibly slowly. Every time I try to type something or click on something the spinning wheel appears and it takes anywhere up to a few minutes for it to catch up. Having searched other threads I've checked how much memory is available, but that doesn't seem to be the problem as I have about 50GB free (the laptop was completely cleared out by the previous user and I've only had it a month so there's not a huge amount on it yet). Similarly the available RAM doesn't seem to be a problem. The only other suggestion I have seen is to repair disk permissions. I have tried to do this, however, I'm having problems as it either gets part way through and then gives up or doesn't even start - it just says reading permissions database. Other than that I've had a look at the Activity monitor, but there's nothing really using up massive amounts of the CPU except, 'installdb' which is using anywhere up to 80% CPU. However, I understand this is something that Repair Disk Permissions starts up and is perfectly normal. If anyone has any suggestions about how to fix this I would be very grateful as it's obviously a brand new laptop (to me anyway). Cheers.
