I am new to SX1, and the reason I bought SX1 was that SX1 syncs the best with Mac OS X's isync, and Salling is also supporting SX1.
I tried to go to siemens site to download the firmware update, but I did not find any firmware for Mac users (there was only one .exe (which I believe is for PCs), and no file for Macs)
Please let me know if I missed something. I will be really surprised if Siemen doesn't allow Mac users to update firmware through their machines. I have 2 macs and no PCs
Then you need to visit a friend with a Windows PC as I don't think Siemens is supporting Mac users for firmware updates. A Siemens service/repair center will do, too, I suppose.
