Here’s a screencast of a tip/tutorial on how to transfer files or folders between an Android device and a Mac. There is a GUI utility called Android File Transfer that’s more intuitive. The only problem is that it sometimes fails [read: crashes] on transferring large files. I found adb technique to be consistent and fast.
I also used adb shell to establish a shell in the Android device. I would then locate the target file or the target directory. Once found, I would copy and paste the path to complete the command:
adb pull /pathOfFolder_onAndroidDevice/filename /pathToMacFolder adb push /pathToMacFolder/filename /pathOfFolder_onAndroidDevice
Using a two terminal window allows me to copy the path onto the other terminal window containing the command. This saves from exiting the shell in order to type the command.
