Good day ladies and gents,
I've had Mac's since my IIsi in '91 and currently the proud owner of MacBook Pro, iPhone and iMac which is just 18 months old...
2 days ago I switched the machine off (iMac) and it hasn't been fully back on since.
Each time I start it it automatically goes into soft boot mode. As the small bar moves across the screen it stops after about 1 centimetre (.4 of an inch) and simply whines and shuts down.
I've tried the old tricks of holding down 'c' and 'd'. On one of the attempts I did reach the desktop and managed to run disk utility which said there were no problems. However, once I rebooted it simply carried on doing the same. I also managed to run Techtool deluxe which comes with the Apple Extended Warranty. Unfortunately it's not fully compatiable with OSX Lion so didn't run properly.
I've not known a Mac to be so knackered before. I have tried the command-R scenario but I don't think reloading Lion OSX is the cure for what appears to be a serious problem.
When I shut down the iMac on Thursday I had Acrobat and Photoshop open, also iTunes and Mail.
I generally use Facetime these days but on Thursday (I haven't used my Skype account for 18 months) I did install the latest version of Skype as someone required a Skype call with me. The software installed okay and I had the conversation with the person though the camera feature didn't work my end. I do wonder whether installing the Skype software has done something to the iMac. However, I don't see that it would stop it starting up completely!
Anyone any ideas?
Back up all data.
Boot from your recovery partition by holding down the key combination command-R at the startup chime. Release the keys when you see a gray screen with a spinning dial.
When the Recovery desktop appears, reinstall the Mac OS. You don't need to erase the boot volume, and you won't need your backup unless something goes wrong. If your Mac didn’t ship with Lion, you’ll need the Apple ID and password you used to upgrade, so make a note of those before you begin.
