My personal experience after upgrading my 2012 MBP with an SSD and 16 GB Ram. Issues I had after my upgrade.
After a fresh install of OSX 10.9.4.
Cubase 7.5 Issues:
Missing midi presets, reverence presets, groove agent presets-EDM midi loops, padshop and loopmash content, were all missing. SCARY
Solutions: Reinstall all cubase versions from 6, 6.5, 7 and padshop’s additional content SOLVED those issues.
Looks like 7.5 needs previous versions. I also had some minor issues with my Native Instruments plugins now all solved.
It was a bit scary but worth it. I would recommend this to anyone but give yourself 24-48 downtime.
Now my MBP can start in about 8 seconds, shutdown in 1 second, Cubase 7.5 loads in 10 seconds. 2 seconds faster than my old HDD. I’m not sure why cubase is not loading faster but samples/sounds load almost instantly.
