FMS Data Update ALL aircraft?

beginner Q. If you do a data update and it says it is going to my XP folder (on a Mac) should not all the relevant FMC’s be updated in XP? It appears NONE of my ZIBO are updating.

Also just checking further on the update page and it tells me under the watch icon that my latest update is 2011. Under Little NavMap it tells me it is up to date.

Very confusing to say the least
