    Why do people write and say 5,1 for the cheese grater. Or 7,1 for the new one. What's with the comma?!

    It's how Apple identifies the model. For example my Mac Mini:

    Europeans often use a comma rather than a decimal point. Can be confusing when talking numbers.
    UK would write 1,098.00 for a thousand and ninety eight.
    Germany would write 1.098,00 for the same number.

    Interesting! That practise in German would initially confuse me until I was informed of it by you. :) For the OP, a period or comma is used to delineate, in writing to indicate a pause.

    ...even, sometimes, when it is, not needed. ;)

    practise? Did your SpellCheck make you "unfix" that? Mine did.

    As said, Apple designates models this way, going at least back to the New World ROM PPC days. I've always suspected it's to look/sound more "European" but could be wrong.

    I attempted to show on a PowerMac G4 (PowerMac 3,4) I had booted up and running, but it seems as though OS 9 does not show those model designations. I've seen them before-I'm guessing they started being reported somewhere in the OS X era, and since I'm actually doing OS stuff on the computer now I don't want to reboot it :)

    I've always read it as e.g. "MacBook Pro 9, revision 1".

    I see you comma here often.

    That explanation doesn't make a whole lot of sense to me given that often times different sizes of the same generation will carry the same major number but different minor numbers-i.e. the 9,1 is the mid-2012 non-retina 15", and the 9,2 is the 13" version of the same.

    Even further, the 2011 models were 8,1 for 13", 8,2 for 15", and 8,3" for 17." The "8" MBPs had several major changes-all got Sandy Bridge "Core i" processors and Thunderbolt, but there was an early 2011 and late 2011 "revision" that carried the same model designations. The late 2011s were a spec bump.

    Mac Pros get even different, since for example the 2,1 is essential one specific configuration of 1,1(dual quad 3.0ghz, where all 1,1s were dual dual). Of course, the 2,1 had different firmware that supported those CPUs, although I doubt many "1,1s" still in regular service still even have their original CPUs :) . AFAIK, the main difference between the MP 4,1 and 5,1 is in the firmware and the design of the heatsinks on the dual processor version. The 5,1 went through two revisions-2010 and 2012, with the latter using a newer processor generation, and Apple didn't update the model designation.

    Reaching way back, look at the difference between the PowerMac 1,1 and PowerMac 1,2. They fundamentally used the same logic board with the main difference being that the 1,2 didn't have an ADB port soldered onto it(the pads are there), but the case uses a totally different color scheme and more importantly Apple put a G4 processor in it. Also of note is that with the release of OS 9.2, they pushed a firmware upgrade for the 1,1 that locked out using a G4 processor in it...

    Slow clap.
