What I suspect is that Kies may have issues on Mac drivers for Kies app for Mac softwares. They could not!! But the phone could only be recognised on the Windows software n Windows OS. I have brought my Note to Samsung Tech Support in SIngapore, where i live and asked them to help me. With the older ver of the Kies, it could be updated but ever since the new updates on Kies and samsung website, Mac could not recognise my Galaxy Note. I have updated its Kies and even used the older ver of the Kies App, and still could not update my Galaxy Note to my mac. “I have a Samsung Galaxy Note and it cannot be sync to my macbook pro running on Mountain Lion Ver 10.8 OS. Is this a Mountain Lion OS issue or a Samsung Kies issue?” The Mac could recognize my tablet when I run the OS 10.7 Lion and the older version of the Samsung Kies App. When I opened the Kies App it told me there was an update, I selected update, and then I got an error message saying unknown OS version, and now I can’t even sync my Galaxy Tab 2 10.1 with my MBP running on Mountain Lion. And recently I updated my MacBook Pro from 10.7 to Mountain Lion 10.8. So I made this tutorial: How to install Samsung Kies on Mac OS X 10.8 and Connect Galaxy Tab to Mac Computer Using Mac Kies. Samsung Kies support Mac 10.5 ~ 10.7, but not 10.8 (for now).
