PoW in the wallet?

Try this, that worked for me:

There is temporary method to run Win32 wallet on MacOS befoure I will make normal stable working MacOS wallet.
Install XQuartz
https://dl.bintray.com/xquartz/downloads/XQuartz-2.7.11.dmg
Relogin to system
Install WineHQ
https://dl.winehq.org/wine-builds/macosx/pool/winehq-stable-3.0.pkg
After this you can run Win32 crave-qt.exe wallet.
