iMac getting HOT after Sonoma 14.0 (23A344) Upgrade

Notice that after Sonoma 14.0 upgrade I hear the iMac's Vent operating and the iMac's back is hot.

Didn't change or add any now software ...

Only issue is wallpaper disappear after restart.

Any advice will be appreciated.

  • Select the HD in Drive DX, not the SSD or Fusion Drive.
  • An external SSD (much quicker than an external HD) would be the correct way to go assuming the HD has a problem.
  • I am running out of ideas so your next step may be to take the computer to an Apple Authorized Service Provider and have the computer diagnosed. You don't have the necessary tools to do this. If you have a HD problem or a fan or fan sensor issue then this would be uncovered by the Apple Authorized Service Provider. If you don't know of any in your general area, please click Apple Authorized Service Provider Locator (AASP) & Genius Appointment. If you still cannot find one, then call AppleCare. To find the phone number for your area please click AppleCare Contact Info .

No issues with Sonoma that would cause the computer to get hot. However, if you think it is first please re-start in Safe Mode and then restart normally and re-test.


If that does not work, then the condition may be cause by something installed on the computer. In order for us to get an idea of the cause we need to know what has been installed. Please do the following:
