What is kernel panic? - Definition from raycompdeequan.tk
If everything seems OK, then shut down and connect the next peripheral. Continue the connect-and-test process until all your devices are reconnected. Safe Mode keeps startup items from being loaded, as well as third-party kexts and fonts other than those used by the system.
Recurring panics can be caused by login items. After you disable startup items, use Font Book to validate your installed fonts. If any fonts come up with errors, use Font Book to disable the indicated fonts. Go ahead and restart normally. If no kernel panic occurs, add one of the startup items back, then restart. Repeat and test each startup item until all have been restored. You can use Apple diagnostic routines to test your Mac. You can use the Recovery HD partition to perform the reinstall.
Reinstalling the OS should replace any corrupt system files, while retaining user data and apps. For more Rocket Yard guides and tricks, please visit our Tech Tips section. Name required.
