Hi guys, Just bought my first MBP, and I really, really need an app that can do the following: I need to be able to sync folders on the mac with folders on an external. I'm already doing this with Time machine, but I need to do it again with specific folders) I need to be able to sync folders on one external with folders on another I'd love for all of this to happen automatically Every app I've found that does this costs almost $10. Any suggestions on free ones? The free ones are all lacking somewhere Thanks!!
