Hi there, inherited an early 2011 MBP i7 2.7ghz 8gb w/ Yosemite. I am quite a new Mac user, jumping from Windows. I'm having a weird problem: after downloading software to install, (Cubase, among others) i receive an error "Wrong Mac OS Version. You need at least MAC OS C 10.6.0 to install the software", but i have 10.10.1. Is this common? Should i reinstall yosemite?
