How to manage Android's filesystem from a Mac? Is there some way that I can explore, and possibly modify, my Android's file system from my Mac?  IOW, I would like to use my desktop Mac as the interface to access and modify my phone's filesystem, thus benefitting from full-sized keyboard and screen, mouse, etc.

(FWIW, my phone is rooted.)

Thanks!
As your device is rooted, you could try to install come SSHd app:


QuickSSHd explicitly mentions root support
DropBear SSH Server even requires it
SSHDroid mentions root as option


So all 3 of them should be able to "export" the full file system via SSH. So on a Mac (and Linux/Unix/BSD as well) you could directly connect from a terminal, or integrate the device's file system using e.g. SSHFS or Fish, on Windows you could use the famous WinSCP -- and probably many others.
