Does this fix the performance issues on Mac?

So I bought 10.5 but can’t use it on my macbook pro because of performance issues. I had to revert back to 10.0, where everything works perfectly.

I am interested in upgrading but don’t want to waste my money on another upgrade that I can’t use, so is this fixed in 11.0?

Well I installed the trial version and it’s exactly the same issue.


What performance issue exactly do you have, please?

Using the exact same project I get the following performance:
10.0 - 10%
10.5 - 75-100% and drop outs
11.0 - 75%-100% and drop outs


If I’m not mistaken, HiDPI support started with Cubase 10.5. Do you use HiDPI screen?
