Can someone give me some help with my MAC wallet?? When I start the wallet, the wallet comes up & then asks to reload the block data I click accept, the the wallet closes.

Loaded the MAC wallet no problem on another MAC - just can't load it on one machine

What about Potcoin-QT wallet ?
you need to make a txt file into a potcoin.conf file, this file will contain a list of IP's (nodes) (at least thats how you do it in windows) check this thread for the linux instructions, those are the closest, please keep us posted if you get it working. If you are still having trouble I'm willing to VM a mac os and check it out myself.
Tried the nodes that were given by creating a .config file with no luck - it's strange I can get the wallet working on my MAC desktop but not my Macbook pro (which is the wallet with the coins in it.) Luckily I did make a backup of the wallet before it stopped, although tried the .dat file on the wallet that is updated but the file wouldn't drop the potcoins in there either :-(
