Yes, in theory there are 3 ways to update. In practice, none are working for me.
1. Mac App Store - but this method is available only if you originally purchased Keynote, from the Mac App Store.
2. Software Update from the Apple () menu -- this method should work if you originally purchased iWork in a box (as I did). But apparently this method is NOT detecting updates for me.
3. Standalone installer - Download the update installer from the Apple Support Downloads page. But the newest update listed there is 5.1.1. and Keynote is 5.3 is listed in the app store.
Is Apple neglecting any options other that the App store?
My OS version on the laptop does NOT have the App Store. Apple Software Update does NOT see an update for Keynote available -- probably because the newest version needs Lion. Apple Support Downloads only shows the newest version 5.1.1 -- again Lion.
I don't want to update the entire laptop system and then other related software to show one presentation without a glitch.
I seem to remember the older versions of programs used to be up on this site ... something must have changed.
So, right now I'm stuck once again in the Apple upgrade loop.
Not everyone who has Keynote version 5 needs the most recent update
Any Apple software update has to be compatible with the OS the last version of the application
Updtates from the App Store are only for versions downloaded from the App Store
Updated available from the Apple web site are for versions prior to version 5.1.1
Updates available from Apple Software Update are for versions purchased on a physical disc
