Failing to install on a mac?

[Barleduq]

I just put WoW on the MacBook Pro I inherited from my daughter. After playing a bit to make sure things worked, I downloaded the core pile of addons I've definitely decided to keep: Addon Control Panel, Altoholic, Auctioneer, Badboy, BadBoy Cleaner, FishingBuddy, Gatherer, GathererDBWoWhead, Lagbar, MoMo Critter Emote and its fan update, Postal, Silverdragon, SpeedyGonzales, TomTom. I Unzipped them one by one, and put the resulting folders in /Applications/World of Warcraft/Interface/AddOns/ - as I have in the past with my Windows and my Linux box.

Of these, only Addon Control Panel, BadBoy, Badboy Cleaner, GathererDB:Wowhead. Lagbar, Postal, SpeedyGonzales, TomTom, and MoMo loaded - that's all that I see in the AddOn screen list available at the character selection screen. Out of 14 addons, only 9 are visible; I'm lacking Auctioneer and Altoholic most noticeably, Postal and SilverDragon next most noticeably, and Gatherer (tho the db loaded).

Clue? Why is this not working?
