Please note: this Mac wallet is not perfect just yet. Our testers mainly reported that starting the application is slow (it can take about a minute or so to load). We have not been able to determine yet what's causing this, so there's still some work to be done. But we are releasing this version, simply because it does work, it's only the initial startup time that's not ideal. If anyone experiences any kind of difficulty other than the initial startup time of the application, then please let us know.
OSX 10.9.3 here and I can report it is working fine. No slow startup - is actually quicker than most other wallets and syncs up fine. No crashes so far either.
Great to hear that!

The "slow startup" was only reported by 2 of the testers, for everyone else it worked very fast too, so it could've just been that the slow start issue was only happening for those 2 specific people. We are looking for more feedback on this - if some other Mac users can let us know whether the application loads fast or not, that would be great.
10.9.3 also here.
I would say it is faster than the BTC wallet, slower than a few others - but generally fine. I will check back with it in a few weeks for staking, but for now it is a nice cold storage for my SAT2.
Thanks. Two thumbs up.
