    Hey everyone, lately I have been having a few strange problems with my latest gen iMac 20" (sig for full specs) and I don't really know whats wrong and how to fix them

    First of all, sometimes when I turn the computer on (not from sleep, but actually turning it on) the cursor on the screen lags. I have a wireless mighty mouse, and most of the time it works fine (it is now..) but occasionally it just lags. And when I say that, I don't mean one second it works the next second it lags, I mean that when I turn the computer on it lags for the whole time until I restart it, and then it works fine.

    Also, lately I have been experiencing random freezing on the computer. I will open Garage Band or something, then the little rainbow pinwhell will start spinning, and it will go for 10 solid minutes, no response from the computer whatsoever, aside from the cursor being able to move. I don't know what is wrong, but it is really annoying and for some reason, it only happens when I other people are in the room. I know its strange. But anyway I was hoping there was some sort of fix. It doesn't freeze often, but it has a few times, say 3 or 4.

    Update: I'm downloading a 9mb file is there any reason why I am getting a 14kb/s download speed while I am paying for 6.0mbps? I know this doesn't realte much to the iMac but I'm just wondering.

    It sounds like your wireless mouse probably has a weak battery or a weird transmitter. From what you say, it seems to me that the signal is getting dropped from time to time. Try replacing the battery.

    GarageBand is a freakin' processor/memory hog. It takes me a while to get GB to launch as well, though it doesn't usually freeze. Try to verify/repair permissions and see if that takes care of it. Probably will. Also, and I know it sucks, don't run any other applications when you run GB. It works best when it has the machine all to itself.

    btw, the reason it only happens when people are in the room? Murphy's Law. You know when you car is making a funny noise, and you take it to a mechanic, and it suddenly stops making that noise? Same deal ;)

    download speed? Could be any number of things, though if you're on cable you're sharing bandwidth with the neighborhood, so you've got to take that into account. At a guess I'd say the issue lies with your provider.

    please note, I'm not saying you don't have other issues, just saying that it's unlikely. Try the simple maintenance things first. If they don't work, report back.

    EDIT: check for updates, too. Some people have reported problems with 10.4.8, mostly laptop users. It works like a charm for me. Run the updater and see what's available. Apple is usually pretty good about sending out updates that actually work.

    Are you connected by the Ethernet or Airport? If its the Airport, then there's a good chance its a problem with the iMac. Have a look on the Networking section over at the Apple discussion forums as there's quite a few people suffering with this sort of problem.
