Sorry if this is the wrong forum, but I really need help. I have an older MacBook Pro - it's a 2.0 Core Duo - with the latest OSX. I haven't had any problems with it and I've had it for over 2 years. A couple of nights ago, I was adding cds to my iTunes 9 (latest version) and I noticed that my TuneUp (a program for cleaning up the iTunes library) had an update available. So I went ahead and let it install the update while I was doing stuff. Maybe not a wise move, but there it is. The installer finished by my TuneUp program never came back on. And then at some point I noticed that my iTunes was no longer responding, in the middle of adding a cd. Then I noticed that I couldn't do anything on my computer and I had to restart by hitting the power button. I very rarely have to do this. But since I restarted, my laptop has been really screwed up. Here's some examples of what's been happening: 1. My start up takes a lot longer and it goes thru a bunch of different shades of blue before it shows me my desktop. Also the menu bar at the top of the screen blinks on and off a number of times before it finishes. 2. Once I have restarted, I run into different problems depending on what I try to do. If I try to run iTunes, my laptop freezes (spinning wheel) and I can't force quit iTunes. I am stuck having to shut down with the power button. If I try running Safari, like I am doing now, it will run, but it will get stuck when I try to close Safari. Sometimes I am able to force quit Safari. 3. I can try to run Mail but I will have problems with it. One time I tried to reply to an email and I could not type. It kept making a beeping noise with every key I pressed. I also have trouble force quitting my mail. It will be onscreen but I can't quit out of it. I have to restart by pressing the power button. 4. I once saw something really weird. My Mail icon was missing from my Dock. The space for the Mail icon was there on the dock and the little label that says "Mail" was there floating in the space but the icon itself was gone. I clicked on the blank space where it should have been and my Mail program started up and the icon reappeared. Very odd. Never saw that before and it only happened once. 5. Sometimes, when I restart, I will get a message that my Finder has unexpectedly quit and it wants to send a report to Apple, which I do. I have a copy of that report if you want to see it. That doesn't happen every time, tho my Finder is quitting. 6. I've been in touch with the tech support of TuneUp since they are saying that they are having problems with their updater. I tried following their recommendations but it didn't help. They said something about the cache still hanging onto the faulty installer. Not sure how to clear the cache they are referring to. I did reset Safari but that didn't help. 7. I tried running Disk Utility. I tried fixing the permissions which didn't help. I tried Verifying the Disk which found no problems so there was nothing to fix. 8. I am visiting family for the holiday, but when I was home I tried to access Time Machine, but kept having trouble with it. I had trouble getting it to come on and then once on, I had trouble using it, moving thru time and the backups. I was thinking I am going to have to go back to a backup from before I ran that updater, but I'm not sure if I am going to be able to access it. 9. Sometimes when I go to Force Quit, I get an empty window, even though I have programs open that could be quit. So at some point, I think my Finder quits without letting me know, making everything else fail to work properly. Thus, the Force Quit doesn't work since the Finder has already quit. I'm really not sure what to do. Something seems really wrong with my Finder. It keeps crashing. How do I fix this? Is my laptop simply stuck trying to install the update to that TuneUp software? Or do I have something seriously wrong? Thanks for your help!
