It is also impossible to launch Acrobat X Pro. It seems like I'm out of ram (I have 12Go on my iMac). For example, everytime I drag my canvas in Photoshop or Illustrator there's a kind of a 'lag'. I own an iMac 27 inches i and a MacBook Air i and have updated OS X on both computers by doing a clean install (saved data on an external drive, erased the hard drive partition then installed Yosemite).ĭespite the fact that the os is a little bit buggy and slow (I'm not talking about the boot but the finder) I also realized that Adobe CS6 isn't running as good as it did with Mavericks and the previous operating systems. However as a professional I deeply regret having upgraded my system. I absolutely have nothing against the fact Apple wants to link OS X with iOS and I really love the new GUI of the system. Unfortunately for the very first time of my life I have to say that I'm very disapointed by the new OS Apple launched last October: Yosemite. As a graphic designer and Apple computer user since a very long time I was always more than satisfied by everything Apple did with Mac OS X which I can say without hesitation is the best operating system ever released.
