Since updating to macOS Serra and LR 6.0 to LR 6.7 
After editing about 1/2 hr in the Develop module, LR hang (with loading.. message) must reboot iMac and this problem keep repeating.

Note: This conversation was created from a reply on: Lightroom CC 2015.7: Badge numbers in Grid view not visible on Sierra.

This sounds like a different issue than is being discussed here. If the whole system is locking up, that could be a bad driver (try disabling Graphics Processor under Preferences > Performance. It could also indicate a hardware failure (failing hard disk, bad RAM, or Graphics Card). It could also indicate a damaged OS.

It might be also helpful to hold down the Option (or Alt on Windows) + Shift modifier keys when launching Lr and try reset the user preferences.
