Macbook Air will only Boot in Safe Boot So after multiple startup problems with my Macbook Air i managed to get it to boot once upgraded the OS to Catalina hoping that it would solve previous startup problems.

Also ran First Aid from Disk Utilities but it still will not boot normally.

I can access Safe Boot but cannot access Recovery or MacOS Utilities ..

I have checked the RAM in System and they both have OK Status so i believe this to be some other hardware or driver issue.

My question is if i cannot access MacOS Utilities or Recovery mode how can i format and reinstall OS to rule out software issues ?
I start in safe mode occasionally when my machine is acting up. I do so because certain startup items, especially 3rd party ones, can cause problems. I'd turn off all startup items and see if that helps with your problem.
