It was brought to my attention that the wallet will not execute on 10.6, I'm looking into this, but can't promise a delivery. iirc, Apple recently dropped support for 10.6, so if you're on it, you should really consider upgrading to 10.9 as you're prone to security risks.
I only have a 10.9 (mavericks) OSX machine. If anyone happens to be running 10.7 or 10.8, please give the wallet a twirl. However, I'm not sure why you'd be running 10.7 or 10.8 either because 10.8 and 10.9 were free upgrades!
If you have an issue, please pm me directly so that its brought to my immediate attention (I can't promise to read every post in this thread).
I am somewhat new to OSX, and to my knowledge even though libc++ and clang++ were present in 10.7 and 10.8, they were not the standard stdlib and compiler until 10.9.
If I don't hear anything regarding 10.7 and 10.8 by tomorrow evening, I'll look into testing on VMs.
Dkfunk. I don't use a Mac, so it doesn't impact me, but it does impact many users in the xxxcoin community. So just wanted to say thank you for doing it and being proactive to help Mac owners by asking them to PM you if they have problems. I've been on many coins where the person that does the Mac wallet just finishes, collects bounty and leaves without offering any help if something goes or is wrong. I'm glad you are part of this great community!
