I have an issue with my macbook unibody 2009. It just will not update or restore an Iphone or Ipad. It starts to load the software into the device but when the progress bar is just underneath the apple "bite" it just stops there. The mac says that it is verifying the software but in reality it has frozen.

I can disconnect the Iphone or Ipad and it will stay the same on the screen. When I go to quit Itunes it says that it is not responding.

Version of Itunes 9.01

Previous version 8's did the same.

Any ideas how to resolve this ?
