Mountain Lion Build numbers…?

Question

Mountain Lion Build numbers…?

Greetings,

I am currently running Mountain Lion 10.8.5 and "About This Mac" reports I have build number 12F2560. I have a MacBookPro9,2 (model identifier).

My question is simply this, this build number does not appear listed on any Apple websites concerning what can be installed upon this MacBook Pro, should I be concerned or this this nothing to worry about…? I have decided to keep Mountain Lion upon my machine and upgrading is no longer an option…

Many thanks indeed in advance for any help offered.

MacBook Pro, OS X Mountain Lion (10.8.5)

You might want to consider starting a new discussion. Since this one is marked solved and is a couple of years old, less people are likely to look at it. A new post would be much more visible. You can link to this one.

You can install the version that came on the discs with the computer or any later build number.

Having that build number means that Security Update 2015-006 was the last relevant update installed on the computer. It isn’t a cause for concern.

I have the same MBP9,2 mid 2012 13inch Intel i5 ( non retina ) About this Mac states software 10.8.5 (12F2560) and under the OSX versions and builds the numbers do match up for my machine.

Can you understand how it can confuse a MBP owner? and whether they are receiving the security updates esp when under system installation is chinese word list update when I am a USA english peaking person
