I don't have a windows and no Linux system on my computers. But even if I had, its not clear, if the wallets work 100%.
Before you really consider pumping prices, adding MN to sites and spreading the word, you should create a Mac OS X wallet and fix the existing ones. Only if they work and its point and shoot easy to set up a wallet, load the blockchain and set up MN without comand lines you will be able to attract the masses.
And I still don't see any reason to invest in it, other that it is limited to 18m coins... And the price is also to high, I would dump you coins until it is resolved. Way to many problems during launch already
If you just want launch new Masternodes you don't need Mac OS wallet. Just buy Linux or Windows VPS and use last version of DAS wallet. All transactions you can perform from Novaexchange. I don't see big problem.
