An Android on the Mac are not a pretty combination. I tried the Kies app for a Galaxy tab with no luck at all. It won’t mount even after the driver install.
I wanted to get some files out of the tab. I tried ES File Explorer with a bit if luck where single files copied over fine.
With ES there is no progress bar so you don’t know what is really happening until it fails ten minutes down the line.
After trying Astro file manager with the samba add-on still I couldn’t connect to my Mac.
At last I tried AndSMB where there is a progress bar and it tells you if the copy failed. You have enter the samba server manually but it seems to work.
Samba Filesharing seems to be another popular one but you need to have rooted device for that to work.
