Mac hangs up on restart
I Have the white apple screen and a load bar at 30% no action for 15 minutes or more. Can I force it to shut down and try again?

If your Mac hangs on boot you may want to force a shut down and try again. On reboot you can try safe mode and see if that helps.
Try safe mode if your Mac doesn't finish starting up - Apple Support
What is safe mode?
Safe mode (sometimes called safe boot) is a way to start up your Mac so that it performs certain checks, and prevents some software from automatically loading or opening. Starting your Mac in safe mode does the following:
- Verifies your startup disk, and attempts to repair directory issues if needed
- Loads only required kernel extensions
- Prevents Startup Items and Login Items from opening automatically
- Disables user-installed fonts
- Deletes font caches, Kernel cache and other system cache files
Together, these changes can help resolve or isolate issues related to your startup disk.
Starting up in safe mode
Follow these steps to start up into safe mode.
- Start or restart your Mac.
- Immediately after you hear the startup sound, press and hold the Shift key.
- Release the Shift key when you see the Apple logo appear on the screen.
After the Apple logo appears, it might take longer than usual to reach the login screen or your desktop. This is because your Mac performs a directory check of your startup disk as part of safe mode.
To leave safe mode, restart your computer without pressing any keys during startup.
If that doesn't help, please see these articles.
