I have a slow boot up, so I wanted to run Apple Hardware Test.
AHT never starts based on http://support.apple.com/kb/HT1509 but AHT does not come up. Tried it 20 times, no success. I have iMac 2011 w/ Lion. What should I do.
iMac, Mac OS X (10.7.3)
If you cannot get AHT to run there isn't much we can do here except recommend taking it to an Apple Store or AASP. Ask them to show you how to run AHT and they should be able to help you out.
DId your computer ship with disks? If so, did you try using the disk to boot to diagnostics? some computers it's disk one, other disk two.
When you say your computter is slow to boot, how long dose it take to boot?
Have you checked the hard drive using disk utility? Dose the disk verify without any errors?
Hi Titan,
My system didn came with the disk. I have used disk utility to repair the disk, because it showed a boot sector problem during disk verification process. I started disk utility using Cmd+R at startup. The problem was fixed. Not the disk verifies without error.
However, the initial gery screen at startup still take more than two minutes after with the apple icon appears.
Thanks.
