Why is Sonoma so slow to start up?

After upgrading to Sonoma from Ventura I find the start up time on my 2019 Intel iMac very slow. From turning on to complete desktop function it takes about 7 minutes. Surely this cannot be right. I have waited for several days to let things settle but it is very frustrating. Is there anything I can do?

iMac 21.5″, macOS 14.0

Disconnect ALL External Drives - Firstly


To avoid the question / answer and question answer scenario


Suggest the User start with Points 1 to 4 and then Test


Still having issues, move onto Steps 5 and 6 and Test Again


Still no resolve - move onto Step 7 and follow instructions therein 


1 - Restart in Safe Mode. This will perform a Disk Repair, clear cache files and only load Apple Software, extensions and fonts. The boot up will be slow and can take some time - Normal.


2 - Safe Mode will also eliminate Third Party Software, extensions and drivers from loading. It will only load the Minimum amount of Core Apple Processes to allow the the computer to function at a reduced Level of Performance 


3 - Does the issue present in this mode ?


4 - Sometimes a Safe Boot followed by a Normal Boot will just put things right.


5 - If not - there could be something in the main User Account playing up. To further isolate this - Set up users, guests, and groups on Mac. Then log out of the Main User account and log into the dummy account and test again if the issue persists.


6 - If the issue is present in the dummy account - then, this appears to be a System Wide issue on the computer.


7 - Download the Application Etrecheck directly from the Developer.
