These useful combinations help start up the Mac properly and fix system errors.

If you can boot up normally or in safe mode to Mac OS X, go to the Terminal app and type:
If you have Lion or Mountain Lion, it’s a safe bet that it does exist. If none of these methods are working, ensure the Recovery volume exists. This key combination should send you straight to OS X Recovery. Try pressing and holding the key combination Command (⌘) R while rebooting or power cycling your Mac, following the bullet points above but replacing the key(s). If you do not see a Recovery volume, it’s either hidden or does not exist. If a startup function doesn’t work and you use a third-party keyboard, try again with an Apple keyboard.If you’re using an Apple wireless keyboard and the above is not working, try shutting down first, then press the power button (power cycling). As soon as you hear the startup chime, press and hold the Option / Alt key until the expected function occurs.What works: press the key(s) as SOON as you hear the chime, make haste!, and hold until it’s obvious you can release. Timing is everything, if you find the expected function is not occurring, you may have pressed too soon, too late, or not held it long enough. As soon as you hear the startup chime, press and hold the Option / Alt key until the expected function occurs.The goal here is to find the Recovery partition, select it, and boot from it.
