Q: restart is not happening
After the initial update: grey screen with notification that the macbook is going to restart (including the AppStore logo) shows and it stayed like this for over an hour already. Should I wait it out or force a restart if possible?
MacBook Pro, OS X Yosemite (10.10.4)

Reinstalling OS X Without Erasing the Drive
Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility and press the Continue button. After Disk Utility loads select the Macintosh HD entry from the the left side list. Click on the First Aid tab, then click on the Repair Disk button. If Disk Utility reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit Disk Utility and return to the main menu.
Reinstall OS X: Select Reinstall OS X and click on the Continue button.
Download and reinstall the OS X Yosemite 10.10.4 Combo Update.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.
