For Mac connection, see the posts above. Basically, download Android File Transfer for Mac, connect your phone, and switch it to PTP mode.hi,
can you help me with my MAC usb connection? i cannot also access my galaxy s3 when i connect it to my white macbook..and by any chance you can tell me what is the meaning of i icon on the left topmost part of my screen?
Thanks.
The icon is the No Notification symbol. See the Notification button in your toggle bar? It's off. Turn it back on. You might have hit it by accident or pressed it without knowing what it does.
