Was macOS 10.14 beta 11 the GM version? I'm currently running that version on my iMac. When I ask for any updates it tells me I'm running the most recent version even if the final version has been released today.
Yes. Beta 11 was the GM.
It had a lower build number than the public release.
But on one of my computers I did not update beta 11 to public release.
I kept beta 11 to see if it would update directly to 10.14.1 beta 1.
It did and so beta 11 was indeed a GM.
The other pre-release betas would not update directly to 10.14.1 beta 1.
That is what distinguishes a GM from other pre-release betas - the ability to update to a point release.
