Hi All, It's very nice to be part of this forum. Since this is my first time posting a thread here and English is not my native language, please forgive me if anything in my thread is not appropriate. I was given a MacBook Pro by my current employer, since I am leaving the company I need to do something with my new MacBook Air, and the followings are the problems I got so far. IOS apps transfer to new iTunes libarary I got hundreds of apps for IOS in iTunes on my old computer, when I was trying to sync my iPhone with my new computer, it said that all my apps on iPhone will be replaced by my library which is 100% empty. And I didn't find any way to transfer all my purchased apps to my new computer. What's the best way to do this? MAC OS apps transfer My old computer has iWork and Office2011 installed, but those are not purchased from the MAC app store. And I didn't find the image file for those installed files in the old computer, my question is that how I can transfer those apps to my new computer without re-purchasing them. Remove apps or turn off updates tracking for specific apps on both mac os and iOS. This is a long term question for me. My old iTunes library keeps tracking available updates for me. Since there are some apps I will never reuse again, how can I turn off updates tracking in iTunes? And can I delete specific apps from iTunes library for the purpose of reducing size of the library? I tried searching for answers to my questions here but didn't succeed, and I don't want to call the technical support. Really appreciate if you could answer all my questions. Thanks in advance.
