I have just upgraded my OS on my mac to Yosemite.
Since I read the following line in a Steinberg official letter, I understood it was ok:
“Please note that current Steinberg software installed before the Yosemite update is not affected!”
Now when I run Cubase 6.5, the logo rectangle pops up, but then it crashes in the middle of the loading.
I tried running Cubase 6.5 on 64 bit mode and it loaded up the program correctly.
I am used to work with the 32 bit mode because of some plug ins that are not supported in the 64 bit mode.
