Customer Question

Why won't anything open when I double click on it--for example, my hard drive?

I just can't open what's sitting on the desk top when I double click on them. I'm running 10.5.5 It's an IMac G5.

<br />Can you try running the following update (The combo updater from Apple)?
<br />
<br /><a href="" target="_blank"></a>
<br />
<br />Once you install and restart and see what happens. Also, will files open on other parts of the disk (in folders)?
<br />
<br />You can also try going to Macintosh HD > Applications > Utilities > Disk Utility, selecting your drive from the left-hand list and "Repair Disk Permissions" and restart.
<br />
<br />I hope this helps,
<br />

That appears to be a Mac 10.5.5 update, but I'm running 10.5.5
Expert:  Marc Schonbrun replied 8 years ago.
Yes, you're correct. However, when you update from Software Update, sometimes there can be issues, so I'm having you apply the larger "combo update" which updates every single component from 10.5 and up. I've seen this fix a large number of issues—it's what I'd do first if my machine was acting up. Try it and the Permissions Repair that I outlined and we can go from there.

Well, it has presumably finally downloaded, but it won't open and I still can't open my Mac harddrive by double clicking on it, or anything else for that matter.

That's what won't open.
Customer: replied 8 years ago.
Apparently it's a package, not an application and it won't open.
Expert:  Marc Schonbrun replied 8 years ago.

I think there are two things that could possibly be wrong. Let's go with the first:

Are you absolutely, 100% sure that your mouse works? Can you click and activate anything on this computer? Do you have another mouse that you can check? I have to think this is the issue because I can't think of anything that would make your Mac this upset.

If that doesn't work...

Go to the Apple menu (top left corner) and open System Preferences
Go to Accounts, and press the + button to add a new account. Make it an administrator account. Now log out of your broken account and log into the new one. Can you open programs there?

I downloaded the Mac Update Combo, but it won't work on my computer because I'm still running 10.4.11. I'm kind of afraid to install 10.5 myself because I'm afraid I'll encounter more problems. My mouse works fine.
