Issue updating iTunes for Mac?

New iPhone 5SE wasn't compatible with my "older" version of iTunes. Updated my Mac's OS to El Capitan now trying to download the newest version of iTunes (12.3.3)

"Issue"? Can you tell me what issue?

  • Will updating to Mac Osx 10.6.8 Erase Data? My iphone's running ios 6 and it got messed up so i wanted to restore it, itunes says it needs to be updated so when i downloaded itunes 7.1 it said mac needs to be updated. Do i have to install the mac osx update? Will it erase my data? ( i don't have a time machine or a back up)
  • Will updating my iPhone apps affect my phone speed as how updating the Operating System (OS) will? Currently I'm using the iPhone 5s on iOS 8.3 I know if I were to update my phone to the latest OS I may notice some slowdown on my phone's performance, since it may not have the "muscle" to handle certain functions. Many apps now are optimised for iOS 9 and/or the 6th generation phones. Will my 5s' speed performance slow down if I update my apps? Will the app's performance slow down?
  • Is anybody else having this issue with iTunes? I have an iPhone 4S and I was editing my music collection. I put all the artwork on there, but sometimes it'll disappear from my phone. The artwork will show on my computer but when I go to albums on my phone, the picture won't be there for a few of them. I have the latest version of iTunes.
