It says that the GLDCoin mac wallet is damaged and can therefore not be opened on my mac, and luckycoin wallet won't connect. Could you look into these problems and solve them?
I've had the same problem on and off with the Luckycoin wallet. I think it has something to do with the Luckycoin network, because it sometimes works fine for me. One thing you can do that might help, if you can, is to forward the Luckycoin peer port (9917) from your router to the machine that's running the wallet.
I haven't seen the GLDCoin problem before. Do you get the dialog that asks if you want to send Apple an error report, and that shows you a preview of the report it's going to send? If so, can you cut & paste that error report and PM it to me?
Also, what version of Mac OS X are you running?
