Is Samsung GT-S5230 incompatible with iMac ?

You can use SOME of the S5230 ( STAR) features in Mac OS X and you can share documents with it :

In all cases the phone needs to have a Micro SD card installed as "hard disk" ( up to 8GB work fine in it ).

The phone supports saving photos and videos either to the internal space which is only a few hundred MB or to the memory card. But you need to set the memory card as the place to save manually - else it will still save to the telephones space ( silly I know ).

You need to save photos,music,videos on the memory card in the phone ( not to the telephons own filesystem ) , you can set the default loaction where to save in the 5230s settings menu, under "memory".

The 5230 knows 3 modes it can connect to a machine. "PC Studio", "MP3 Player" and "USB Mass Storage".

MP3Player is only usebale in connection with Windows Media Player 11. Itunes can't handle that device.

Now when you plug the 5230 to a Mac you must choose "USB mass storage" as connection to get to the memory card.

This way the phone's memory card will appear in Finder as external harddisk, and thus you can access the files on it.

This phone is usable on mac/linux only in this mode for file access. The "new pc studio" software that would enable all the othe features plus access to the phone system runs only in Windows.

The 5230 has also a data/fax modem , but this is not supported in Lion, only in Snow Leopard. ( to enable that you would choose "PC Studio" as connection type when you plug it in the mac , and then OS X will report that it found a new networking device - a modem . )
