My Mac Book Pro has the proverbial "spinning wheel" problem and seems to have picked up a virus, possibly through iTunes. When I use the disk repair it shows that there's a problem in iTunes but the disk repair cannot fix the problem. This has become a real problem and I'm not comfortable with loading an anti virus program. Short of visiting an Apple store for help (closest is 2 hours away) I'm wondering if there's anything at all that I can do to get my Mac well again. It seems to be pretty sick right now and I need it back ASAP. Any help would be greatly appreciated. Thanks in advance

You say that you are not comfortable loading an anti virus program, but it's not a bad thing to do, and a good first step here...

 

This is a good, simple, and free Mac AV to use...

Another option is ClamXav. Or use a backup and restore the machine to an earlier date.

What makes you think you have a virus?  I've yet to see, but one virus on a mac in years. In most cases when someone has malware or scare ware. 

 

Did you run a disk repair from recovery mode? (hold cmd+R, while booting up)  Did it say it "could not repair disk backup your files" or was it greyed out? 

Doing a disk repair may help with system slowness or App Hangs "spinning wheel" , but it won't touch malware. 

 

Try booting to safe mode first hold down shift key while booting until you see the apple logo with grey screen. Safe Mode is slower, but see if the issue continues there.

 

Can you provide more info?  RAM , HD space , OS X.  This can be found by clicking the apple Icon and choosing about this mac from the menu.

Staygold512 thanks for your reply. I don't know that I have a virus--just guessing really. I was able to run the repair disk in recovery as you suggested. It said:

  • "The volume Macintosh HD appears to be ok".
  • Volume repair complete
  • Updating boot support partitions for the volume as required

Then I did a "Permissions Verify" and it came back with a ton of stuff in there and took quite a while to complete that. Then I did "Repair Disk Permissions" twice. Question: If I verify disk permissions and then do a repair how do you know if it fixed everything it found during the verification?

 

Now, if I shut down and restart in safe mode as you suggest and the issue continues what next?

Here's what I got on the verification on the disk:

 

The one at the top of the list says SUID file "System/Library/CoreServices/RemoteManagement/ARDAAgent.app/Contents/MacOS/ARDAgent" has been modified and will not be repaired

 

On repair permissions there's one for System Library, one for Safari and a boat load for the iTunes app - all say that they should be drwxr-xr-x; they are rwxr-xr-x's


What's the next move please?

 

By the way, info you requested:

OS X Lion 10.7.5

Memory 4 GB 1067 MHz DDR3

Hard Drive is 320 GB

 you might check to see how much free HD space you have. that can be done by checking available space in disk utility when selecting the MacHD. 

I would recommend 10-15GB minimum. 

 

You can also check activity monitor, Finder > Apps > Utilities.  http://support.apple.com/kb/ht1342

 

If you are still experiencing issues in Safe Mode, then it might be a hardware issue. You can run a on board Apple Hardware Test, but the diagnostic tools at a Apple Store are usually better. http://support.apple.com/kb/ht1509

 

 

I'm currently having similar issue, and will probably erase & reinstall.

I wouldn't worry about them, crazydiamond23.

While I really like the Mac world I have had my fair share of problems with Macs. This computer had the hard drive replaced in 2010 while in Paris and it was done at the Apple store at the Louvre. Prior to that it worked fine and was a great buy. I have since purchased and use a Mac Book Air and bought that machine because I was told a flash drive was more reliable than the traditional hard drive. Guess what? The flash drive crashed as well and had to be replaced. It's worked fine with no problems since replacing the flash drive.

 

So, back to the Mac Book Pro. If I don't have to worry about the permissions messages I'm back to square one and the problem still exists so where to now? The Apple store, where the closest one to me is a 2 hour drive. I'm willing to make the trip if that's what it's going to take but in setting up the appointment I'll need to give them some information about what the problem is. Any suggestions would be greatly appreciated and thanks to everyone who has offered suggestions. I appreciate it :)

You'll need to pinpoint what's causing the beach ball. It could be your hdd is getting full, not enough ram or a runaway process that's using up the cpu just to name a few.

Just an update and more to come after tomorrow..........I spent HOURS and I do mean HOURS on the phone with Apple support today and as it turns out,this was a HUGE problem that really gave them fits. When we first started it was so bad that we couldn't even do a backup before trying anything else. SO, fortunately, I had a "Test" user profile that was created some time ago and we were able to access the system via that user profile and we made huge strides there. Some unnecessary files were deleted and some software programs that are no longer used were eliminated.

 

Once that was done we went back and logged in under the normal user profile and the tech was giving instructions to do some other stuff that I actually can't recall but once we got to a certain point I was able to access my external Lacie hard drive and do a successful backup. We're going to get together tomorrow morning and upgrade Safari and do some more work and I'll report back after all is complete. Hopefully what I'll have to share will be helpful to all who are interested.

Sounds like possibly some 3rd party software causing an issue, or disk/file corruption. I'd be interested to see what the resolve is.
