looks good, Apple states 10.11 as minimum on Apple page AND on iTunes store
but the update only shows up on Mac Pro with 10.12 and not on Mac Pro with 10.11
On a Logic forum i read it needs 10.12 but apple clearly states 10.11
The App Store has a glitch, always has, so if you're on macOS 10.12 and don't see the update, move the Logic Pro X app from the Applications folder to the Trash (don't empty until verified the new install is good). Then launch the App Store, Purchases, Download.
Logic isn't as complex as it seems. Motion is way more complicated. I use it weekly, and this is another huge upgrade in a dot something update. Wish FCPX team could add features and such as fast and as abundantly as the Logic team does...
I have tested it over the weekend and this is a great update.
The new Studio Strings are sounding good and very easy to program.
Logic is really becoming a complete DAW package, there is not much need for external plugins anymore.
For such a large update this has been very stable so far.
