I went through the disk utility steps and everything worked fine, all of the first aid procedures worked but my computer still only boots up to 3/4 of the start up bar and then nothing happens four hours. What did I do wrong?
iMac 21.5″, macOS 12.2
Hard to say because you did not provide the exact model of the Mac. You can get the exact model by entering your serial number within this Apple article:
Check Your Service and Support Coverage - Apple Support
Run the Apple Diagnostics to see if any hardware issues are detected. Unfortunately the diagnostics won't detect a lot of drive failures or other issues.
Try booting into Safe Mode. It will take longer than normal to boot into Safe Mode because macOS is running a file system check and other things such as deleting some temp & cache files.
Also, when running First Aid, you should run First Aid on the hidden Container instead of just the "Macintosh HD" volume. Even if First Aid says everything is "Ok" click "Show Details" and scroll back through the report to see if there are any unfixed errors listed (First Aid sometimes lies about the results of the scan). If there are any unfixed errors listed, then you will need to erase the Container (if an Intel Mac, erase the physical drive) and restore from a backup or clone. Within Disk Utility you may need to click "View" and select "Show All Devices" so that the hidden Container appears on the left pane of Disk Utility.

You may also want to disconnect all external devices in case one of them is causing a problem.
If these things don't help, then most likely you will need to have Apple or an AASP examine the Mac.

You did not take it to your local Apple Authorized Service Provider to have it diagnosed, that is what is needed.
A little confused. Still not working.
