Something critically wrong with any drive that takes that long to boot up.

Have you booted into Recovery and ran Disk First Aid to see the state of the hard drive? Next how full is the hard drive? Are you running any cleaning or AV software that is in 'Startup Items' in System Preferences?

Unplug network cable(s), turn off wifi, and reboot -- still 4 minutes? If so, then I agree re checking out your disk drive, and looking for malware. If disconnecting all networking helps, look for a DNS mis-configuration or some other sort of network related problem.

2013 imac sierra


thank you
Try going to the Startup Disk panel in System Preferences and make sure your internal drive is selected as the boot disk. If you do not have that selected, the system will search all around for available boot drives before finding the internal and moving forward.

Sounds like a hard drive failure. I would do a complete reset of the computer. Install OS and try again. Be prepared for the drive to fail during the reinstall (it stresses the hard drive out). But the clean install might fix issues that are underlying.

The reason I suggested an external SSD is that on my last HDD-only (Late 2009) iMac it was taking several minutes to completely boot to the desktop. I don't think it was 4 minutes but it was well north of 2.

The point is that it is possible to install enough apps on a HDD-based Mac that it takes several minutes to completely boot with a spinning drive.

Barring that, I agree that a failing HDD is the next logical conclusion.
