skycoin, cardano, karbowanec i believe are all qt wallets? They all worked and installed fine.
i cant signup for airdrop until i can install because need to get an address.. :/
Sorry to hear that you're having problems with the OSX wallet. I'm working on a website that can generate an address and private key so that people who can't access the wallets can still register in the airdrop. I will let you know when it's ready and i'm going to look into the wallet issue as well.
