Hi all,
I had Cubase 5 running on Mountain Lion - mostly fine.
I updated the machine (on a clone on a separate disk - I can boot back to ML if need be - so I’m not entirely sunk) to the latest Yosemite. Cubase 5 is now giving me a segmentation violation on startup in com.apple.main-thread. (I know what a segmentation violation is - been a UNIX guy for > 2 decades)
I had seen a few others report elsewhere on the web that they had Cubase 5 running on Yosemite . But no instructions. I’m very happy making command line changes if there’s something that can be done. I already tried removing the relevant plist files. No dice.
I fully well know it’s not supported. Not my concern at this point. Yes I would upgrade to a later Cubase, but that’s to come later, not this week 
and I’d like to have it running in the interim if possible.
Has anyone here managed to get it to run successfully on Yosemite? I know the 5 installer program won’t work on Yosemite - nor the Steinberg alternate installer - 6.X and up from what I can tell.
Any thoughts? (Upgrading Cubase is not an option for the short term - looking for actual suggestions to get 5 running on Yosemite 
)
Kind regards
Derek Jones.
I hunted around and found a couple of suggestions, including reducing the number of fonts. It does now get to the “GUI resources” part of loading, then dies in the same thread. I have under 300 fonts loaded, and I noted that a previous poster (albeit with 6.X) noted they had 400+ fonts. Wondering if there are issues with specific fonts.
I also checked skin.srf - as was noted by others. Not that either.
It does work under Yosemite for some - here’s an example:

So - at least one person has it working - and - I don’t have a Retina display - so I should not run into the same issues noted there. But, still can’t get over the starting issues.
Any takers? :-/ ?
Kind regards
Derek Jones.
Hey boys and girls
I got it working. It
WAS fonts.
I decided to try ditching simply the ~/Library/Fonts folder contents - which, as I recallfrom originally installing those fonts back in 2013, and from inspection of the fonts.dir file, was a carry over of some TTF fonts from somewhere else.
Anyhow removing those - Cubase starts just fine So, yes, Cubase 5 works on Yosemite. Now, I haven’t stress tested it, just saying it fires up OK.
Oh - and in case you’re wondering, I use CDock to get the 3D dock LnF back. This really is Yosemite!
