OK I HAVE TRIED THIS. i updated to mavericks without even thinking about itunes 11, unfortunately it wiped my 10,7 but i got rid of 11 and did the pacifist way and got 10.7 again only to find it completely ****** my system, all of a sudden songs are stopping at random points, process ituneslibrary.blahblah keeps self quiting and popping up annoying warning messsages, also NOTHING could be updated or redownloaded off the app store while 10.7 was installed.
i attempted to fix permissions, this only made my itunes entirely inaccesible, now i have bitten the bullet and gone to 11, be smart and don't fall for it, if its too good to be true (ie free os) theres often some catch related to self interest brewing behind the scenes. theres such a headache involved with downgrading an os so really don't jump in, osx 11 is right around the corner, the new features are easy to overlook, my pc does run cooler but i lost the last version of itunes i enjoy operating and the piece of mind that it was my computer to do with it what a choose. like come on you got rid of front row and coverflow, weren't they the two big things innovated for osx in recent times that really made the mac feel less like a computer and more like a personal experience? oh thats right, money to be made. excuse me but when innovation was a regular thing for your company the focus was never on "what features can we steal from the next osx to make our customers buy more activity specific products?" before you are the sinking ship merely being pointed in the right direction realise what made you great and don't stop, not the weight or the thinness, it's the usability and the personification
