I just spent the weekend testing both Cubase 8.5 and 9.0.1 on a Mac Pro desktop (2012). I tested both Cubase versions on (3) internal drives - (2) SSD drives and (1) mechanical. On these drives I installed brand new copies of Yosemite, El Capitan, and Sierra (all latest versions). After testing multiple projects of varying sizes, it became quite clear that the performance of both Cubase 8.5 and 9.01 under Yosemite (10.10) was quite better than either El Capitan (10.11) or Sierra (10.12). Everything seems to respond quicker, especially when switching between tracks or making multiple audio/midi selections in the project window. I reinstalled Cubase and each system on all (3) internal drives with the same results. I find this especially problematic, especially considering that Cubase 9 is not even supposed to be officially supported under OSX 10.10 or below any longer. If I was able to make these comparisons by myself in a single weekend, shouldn’t the beta testers for this product have discovered these issues as well? I have not had the chance to test any current versions of Cubase on a PC, bu there are definitely issues on the Mac system that need to be worked out. This is also why I rarely update systems any longer until I have to. After over twenty years of using Mac computers professionally as well as testing them, I find these days that very rarely do new system versions on the Mac actually improve much of anything, especially performance wise. After coming to these conclusions from further testing, it looks like I won’t be updating anything any time soon at this point.
