Hi Guys, Iam new her. I got a new Macbook Pro Retina couple days ago. (Brilliant ) I just have some problem, i have tried to install couple apps also not original to get my songs from iphone to mac. It didnt work none of 3 but thats ok i will try that later, i delete everything from this apps. But there is one pop up windows show every 2 second that application mobile_fs_util ist not able to start because of problem with developers check if mobile_fs_util works with this version of OS X. Obviously you need to reinstall the application. Be sure to install all available updates for applications and OS X. ..etc Dont have any idea whats that...i had an application call iphonedisk and it says thats from it but i think i erase everything and cant find nothing Please help, and sorry for my english.
