Imac 21 on MAC OS 10.8.3 very slow startup

Hi There,

We are having issues with a 5 months old Imac 21 running OS 10.8.3. It was fine until I did restore a file that got weirdly lost.

The restore itself went fine and was quick.

So I did restore from a time machine backup, and then Time Machine told me to do a fresh backup, so I did. It took about 9 hours to complete.

Since then, from the moment I switch on the computer until it comes to login, it takes about 10 minutes.

Any idea why this keeps happening ?

Thanks for your help,
Adam.

Boot while holding down command-R to boot from the restore partition, but instead of choosing Restore, choose Disk Utility and then Repair Disk. Let us know the results.

What do you mean by doesn't work? Won't boot into recovery mode? Repair Disk doesn't repair? Or you repaired but still have a problem. Please be more specific.

When you ran the repair did it say the disk was repaired or did it report any remaining issues?

Go to the Users preference panel and create a new administrative user. Then restart and log n as the new user. Is this now faster? If so, then the problem is a user setting or startup item.

Create a new administrative user doesn't solve my problem...
When I switch on my computer it takes about 10 minutes before I have to choose between users......

How much room do you have left on your hard drive. If you are running out of room that could cause the problem

Note that I have a iMac with Fusion Drive (flash storage)... Maybe it changes something...

If it is a fusion drive, I believe it shows up in Disk Utility as two separate drives. Did you run Repair Disk on both?

There have been reports of problems with the fusion drives, and I would be tempted to take the computer to a Mac Genius Bar as it is still under warranty.

Before you do anything else, go into the Startup Disk Prefs panel and make sure your hard drive is set as the default startup disk.

I repaired both...
The hard drive is already set as the default one...

Actually on reading further about fusion drives, I think it should have shown up as only one drive in Disk Utility, not two. I wonder if somehow you have decoupled the fusion drive?

I am really out of ideas at this point, and as the computer is still under warranty, I would recommend taking it to a Genius Bar.

You said the computer is 5 months old. I thought all Apples had a one year warranty.
