My iMac will not boot up, it only goes halfway along the progress bar then shuts down and repeats. I have put in recovery mode, deleted the hard drive and reloaded the operating system, still no fix. Is there anything else I can try?
Try Safe Mode, as per > Use safe mode to isolate issues with your Mac - Apple Support
note: you may need use a usb keyboard if your wireless devices have become un-paired
If that doesn't help, make a service appointment at your localĀ Apple Store orĀ Apple Authorized Service Provider.
