Macintosh Fix for "Failed to activate core devices" error on Mac.

For those of you that are receiving the "Failed to activate core devices" error on the Mac, here is an easy step-by-step fix:

0. Make sure you've already downloaded and installed the MapleLegends client (MapleStory.app) into your Applications folder. As of writing (Feb 13, 2017), the latest Mac client can be downloaded here: MEGA | Google Drive

1. Download PortingKit here.
2. Unarchive and install the app to your Applications folder.
3. Open PortingKit.
4. Click on the Library tab. Make sure you're sorting by Local, not Server.
5. MapleStory.app should be detected and should appear in this tab. If not, you'll want to click "Add" to add it to the list. Click "Play".
6. PortingKit should update your Wineskin wrappers and launch automatically. Don't worry if you're seeing a black screen for a bit; MapleLegends should run normally after a minute or less.
