Step 3: The amount of RAM in your PC will be listed next to MemTotal, in kilobytes (kB). Divide by 1,048,576 to get the amount in gigabytes (GB) that's not being used by the Chrome OS system, then round up to get the amount of installed RAM. For example, the Chromebook used in this how-to shows 16248736kB. When divided by 1,048,567, the result is 15.59GB. Round that up to 16GB, which is the amount I already know is installed in the laptop.

And outside of a brief diversion to escape the pain of Windows Vista, I've never found much reason to want to secede to a Mac.
