I am a new GS2 user. My phone's OS is v. 2.3.3 and my MacBook uses OSX 10.7.2. The MacBook will not recognize the phone, so that I can access the latter's memory and load media files. I want to be able to use Kies but this software cannot locate the device either. I have installed the device driver from Kies 1.0.2. I have turned on mass storage in settings, etc but the two devices don't communicate. What am I doing wrong? TIA.
