iMac Line (2012 and Later)
Safe mode (press the power button, and when you hear the startup chime hold the shift key down at startup). It can take much longer to safe boot (10 min) so be patient.
How to use safe mode on your Mac - Apple Support
Safe mode forces the OS to clear certain caches and logs and do other miscellaneous housekeeping. It's non-destructive to user data so is safe to do. Very often certain weird software behavior is corrected by simply logging in this way as a troubleshooting method. When you're in safe boot, the machine will not be at its best performance, especially with graphics, but that's expected.

While booted in recovery, use Disk Utility and run First Aid on the boot drive.
• Launch Disk Utility, then click View > Show All Devices.
• Select each indented volume of the top most device, and working from the lowest indented volume run First Aid on the volumes, then on containers and finally on the drive device itself. Run Disk Utility > First Aid until all volumes, containers and the drive report to be repaired and/or okay.
• When DU reports the task complete, then restart and attempt a safe boot again.
The problem is that when I start in safe mode it freezes on the logo at the position where the bar is about 95% complete
Are you giving the machine 10 minutes (or more) to complete the safe boot?
What year iMac and which macOS version?
