Hello! My tablet: Samsung Galaxy Tab 2 with Android 4.0 My computer: MacBook Air (2012) with OSX 10.8 I want to transfer a bunch of images to my tablet. Connecting my tablet with USB to the Mac, and using the "Android File Transfer" app, I can browse all the folders on the tablet. I can download any file off my tablet. HOWEVER, I cannot upload any files to my tablet!!! Why? Can I only transfer files to a specific folder on my tablet? Is there an option in my tablet settings that I have to toggle, with regard to security, files, network usb or other settings? During file downloads, or trying to upload, the tablet screen momentarily changes to a screen titled "MTP application" or something. Does that mean my connectivity is using "MTP" ? Is that good or bad?
