Hi, Apologies in advance for the silly question but I am unsure about something. Currently running 10.6.2 on an iMac (2009) Haven't updated the system software in a while and thought its about time I get the latest versions available to me. So i checked the system update menu and these results showed up: (scrren grab attached) Whats the best way to go about it? -Tick all boxes and update the whole lot in one go? or -Tick the MAc OS X update first, update that and then do the other 5 items seperately? -Also will I loose my wifi settings or will it all stay in tact? Thanks!
