Its a bit strange…but good to know that!!! Tried it…and it worked.
I got myself into this cruise boat with out auto pilot. After wiping my entire drive, and rebuild the RAID, I wondered “HOW could it be possibly not to install any version?” The answer is PRAM. You need to reset your PRAM. Your Mac stores certain settings in a special memory area even if it is turned off. On Intel-based Macs, this is stored in memory known as NVRAM; on PowerPC-based Macs, this is stored in memory known as PRAM.
Information stored in NVRAM / PRAM includes:
- Speaker volume
- Screen resolution
- Startup disk selection
- Recent kernel panic information, if any
How to do?
- Shut down your Mac.
- Locate the following keys on the keyboard: Command (⌘), Option, P, and R. You will need to hold these keys down simultaneously in step 4.
- Turn on the computer.
- Press and hold the Command-Option-P-R keys before the gray screen appears.
- Hold the keys down until the computer restarts and you hear the startup sound for the second time.
- Release the keys.
After resetting NVRAM or PRAM, you may need to reconfigure your settings for speaker volume, screen resolution, startup disk selection, and time zone information. Also OS X does not store network settings in NVRAM / PRAM.
Enjoy!!!
