Anyone using Squeezebox server on Mac OS X?

No problems here with a Mac Mini running Snow Leopard and now Lion. One annoyance, though, is that the preference pane only runs in 32 bits, so I have to wait for it to restart the Preferences app in 32 bit mode every time I want work with the preference pane.

Caudio2011 - As far as automatically saving a file ripped on another computer to the one running the server, I have not tried this, but you might try mounting a shared folder from the server computer on the desktop of the ripping computer and directing the ripping program to save the output to that folder. Not sure that is a good idea because of the slow speed of moving the data across ethernet, relative to the speed of the rip being done. I haven't bothered because I make backups at the same time I move files to the server computer so it would actually slow the process down to rip the files directly to the remote server computer and then move a copy across the network again to the backup disk.

Caudio2011 - to share the external drive connected to the Mac Mini, open the "get info" window for the external drive by either single clicking on the drive icon to highlight it and typing command-i or selecting get info from the finder File menu. Once the get info window is open you should see a check box under the "general" section for making the drive a shared folder. Click that box and close the window. You now should be able to mount the shared external drive on your iMac, assuming sharing is turned on for the Mac Mini (under System Preferences->sharing).

You will probably have to enter your Mac Mini password to change any file name or location on the shared folder after this. I recommend not trying to change file names on the external drive from in the image mounted on your iMac - I have had nothing but trouble (files disappearing until rebooting the remote computer) doing this.
