UPDATE: Added PhenixCoin wallet.

Several people have been making an effort recently to get some of the altcoin wallets compiled for Mac OS X. Posts about them have been pretty scattered, so I'm starting this thread as a master list of Mac altcoin wallets, as well as a single place to discuss them.

This thread is meant for end users. We have a good Mac wallet development thread going here: https://bitcointalk.org/index.php?topic=205017.0

Here are the Mac altcoin wallets I know of. Let me know if I missed any. I'll update this list when I find or build more wallets.

DISCLAIMER: I can only vouch for the quality/security of the wallets I've built myself, but I've been using many of the wallets here for quite a while with no problems.
