itunes software update
Could someone please tell me why or if it necessary to continually be updating the itunes software (or any of the macbook software updates in general)??
Also, when we update softwares, is it taking up and occupying more space (because I noticed updating itunes takes about 70 MB)? Or does it replace the previous edition of the itunes in terms of MB space on your computer?
(Sorry if my language isn't highly descriptive with proper technical terms.)
Thanks!!
