all i can say for my part is:
My system runs perfekt with 10.10.5
There is really no need at all to upgrade the OS at all.
Its not an easy task to keep a extremely complex DAW up to date for every OS update.
It makes no sense blaming Steinberg for that. Of course they want compatibility as fast as possible.
But it is often not easy to predict when a final release will be ready.
Also even Cubase is one if the big DAW’s, it is still a small market compared to other big software companies.
That means that Steinberg dont have an army of developers like Apple or MS.
So, things take more time as we users would expect.
I feel sorry for the users who have bought a new MAC with 10.11 pre installed.
They have to wait.
Again, i am extremly happy with my current system.
There is nothing about 10.11 that would make it really better.
Ok, the Notes App is better.
Wow, now thats important.
