How can I view/inspect my Mac’s Parameter RAM (NVRAM)? Inspired by this question I started looking for apps that allow to read the data saved in my Mac’s Parameter RAM. Aside from a very antique (pre OS X) application for Classic, I could not find any. Is there any way to access the info stored in the PRAM on current Macs?
To clarify, for PowerPC based Macs, this memory was called PRAM, but for Intel based Macs, the proper name is NVRAM.

To show the contents of the NVRAM or even manipulate them, you can use the nvram shell commando in Terminal. For info on usage, execute man nvram.

If you just want to display the entire contents of the NVRAM, you can execute it with th -p parameter:

nvram -p
