Nuendo 5.5.6 on OSX 10.9 Mavericks

I’ll seriously keep that in mind. Thanks for mentioning.
If 5.5.6 turns out to be solid on this new SSD with OS 10.9.5, I may just stay put.

I’m getting a 1" 8 track tape machine and simply need a simple and solid DAW without further bells & whistles.
Some DAW editing, audio to midi notes for a kik or snr sample sometimes…pretty basic needs.

I did get a new dongle a few years ago (I think when I got the ver.5 upgrade).

Any further specifics on any N5.5x & OS 10.9 incompatibilities much appreciated as I set off down this path.
