I dont understand what do they put in an update such that their compressed setup package for update comes for more than 65 MB.. I doubt if people at Apple understand the word "redundancy".. (I mean they should have removed files which are not updated in this release and should not include them in so called 'UPDATE' LOL..)
And if you want to know about a frustrated user like me, even after downloading this whooping 65 MB, it will give you a small n sweet message-box saying 'Update could not be applied, please retry later!!!' No saved copy of update (they save it in temp folder, and would delete the package as soon as you dispose the notice message-box!!)
What an amazing software engineering example!!
