I have the latest iTunes running on a high-end MacBook Pro. It now freezes EVERY time I start it. Furthermore the entire UI freezes, not just iTunes. Every 20-30 seconds I get a very brief window of opportunity to kill the app, but if I miss that I have to wait another 20-30 seconds. Not even an iPad or iPhone attached.
Come ON Apple!
i too have this problem. after some digging and fiddling i have found that opening itunes in safe mode will help ALOT with performance. the safemode IN ITUNES (*not Win. safemode*) disables the plugins and crap so all you have is music and your ipod/iphone/ect. with nothing to slow you down.
to open itunes in safe mode:
1. hold CTRL+SHIFT (if a windows pop-up opens saying to "let this program make changes" KEEP HOLDING the keys and select yes.
2. now an itunes window will popup and tell you that your plugins are disabled.
and to get back to regular itunes, simply close it and reopen it like normal. unfortunately you have to do the key commands everytime you want to open in safe mode.
hope this helps.
