Current wrapper is not stable at all. But we will release the new one very soon. Till then please use this beta wrapper:

The file was uploaded from our dev studio in St. Petersburg to a site accessible for our players.
Please give it a try to see if this version is more stable for you to launch and play World of Warships.
The link to the beta Mac wrapper shows promise. If you can give it a try we may be on the right direction to finding a stable version for our Mac OS community.
