I've switched from an iphone to a galaxy s3 this week. I am a Mac user and need an iTunes alternative. I've tried downloading doubleTwist and Kies to use as sync programs but cannot get either to work. I was able to contact doubleTwist and Samsung Kies tech support and was informed that my OS X is too old to support these programs. I'm running OS X 10.5.8 on an 8 yr old non-Intel iMac G4 1.25 ghz processor. My question is there any other alternatives? I'd hate to have to return this phone for an iPhone 5. But as of now it seems like my only option. Please advise on what my options are, if any. I'd like to be able to sync my music that is currently housed in iTunes. Thanks.
