"Beware - local syncing now disabled."0.5 starson by PWAH
Pros: Unknown. Luckily I did some research before I took the Mavericks update. You should too.
Cons: Local syncing has been disabled
Summary: I'm writing this as a warning to Mac OSX users. The new Mavericks update takes away the ability for users to sync calendars, contacts or anything else via USB cable. If you take the Mavericks update, you will be forced to use iCloud for all syncing. That creates a host of problems. Google the issue and decide for yourself. Privacy is a huge issue. Not being able to sync overseas without incurring huge data bills is another. Lack of ability to decide how YOU control YOUR data is another. Be warned. And if like me and many others you think Apple should change its decision to disable local syncing, let Apple know through their feedback option.
