"1. 1GB=1 billion bytes; actual formatted capacity less."

The operating system plus preinstalled applications take up space from the installed flash storage.

Yes, I understand all that. I have a regualr MacBook pro as well and yes, the OS and software take up space. And yes, actually formatted capacity is less. But what I'm saying is that the drive on my new MBP Retina was sold as 512 GB but when checked on Disk Utility, comes up as a 500 GB drive. My regualr MBP was sold with a 500 GB drive and comes up listed as 499.25 GB. That is pretty close. A 0.75 drop is understandable. A 12GB drop is a different story.

Yeah. The "768GB" SSD formats out to 750.42GB.

Click on the Apple logo and hold down Option and click System Information. Go to Serial-ATA and look at the model number of the disk. Is it labled as 512 or 500? Since it's Retina, there are SSDs that are 500GB and 512GB sizes, maybe Apple cheaped out a bit. It's possible. In a situation like that, you could very well contest the issue with them until they fix it via swapping out your laptop. If the box says 512GB HD and you get a 500GB SSD in it, that's not 512GB. There's a problem there.

Well, under Serial-ATA it says APPLE SSD SD512E, Capacity 500.28GB.
so my guess is that it is what they are calling a 512 gb drive. It's not that big of a deal. Just seems strange that a 512 gb drive would only have a capacity of 500.28 GB. 1 GB is a lot of data. 12 is a whole lot. In any case, the computer is great. Was just surprised.

The 64 GB Microsoft Surface has got only 23 GB available, but it's strange that the 512 GB MacBook Pro has got only 500 GB available. Anyway, open Disk Utility, select the hard drive at the top of the sidebar and go to Partition tab. Is your main partition using all the space of the hard drive?

Then I'm going to take a wild stab here and say that Apple is buying the smaller 500GB units and branding them as 512GB units since they control the branding process of the HD logic boards. Just FYI, Samsung makes two types of SSD drives in that similar size. One is 500GB and the other is 512GB. The 500GB one is a non-Pro series and has a slower write speed. The Pro series 840 512GB drive has a much faster write speed.
