I have multiple macs, and some software updates are >1GB in size (e.g. iMovies). I have downloaded the standalone updater so that I can apply it across multiple machines, but when I attempt the installation it says that the software was purchased through the app store, and must be thus updated through the app store - this means that I have to download it 3 times for my 3 machines. This is not practical in countries with slow internet connections.
I am desperate to find a solution to this please.
