Thanks for responding, I'm trying to get this 1.1 mac wallet updated asap. I have a 2.4 Ghz Intel Core 2 Duo, 4GB ram, running latest mac os mavericks 10.9.2. I'm not sure what to do if I can't get my wallet upgraded in time for the fork. I have backed up my wallet keys at least so hopefully I will not lose my coin. Thanks in advance for any help you can offer me.
Don't worry, as long as you don't make transactions with the outdated wallet after the fork you won't lose coins. You could forget about EMC2 and update in a month and your coins would still be there.
