The current release version of the Mac launcher (version 1381807) is unfortunately experiencing a crashing issue for some users on the latest Mac OS X 10.13.6 operating system. There is a beta version available that should resolve those issues for affected users. It can be downloaded from the following URL:
Users encountering this issue will need to reinstall the launcher.
Please note that when starting the reinstalled launcher for the first time, users will have to cancel the automatic update so that the launcher does not update itself back to the release version.
After canceling the update click on EVE Launcher in the apple menu at the top of the screen, select preference from the drop down menu and then change version type from release to beta before clicking on "OK" to confirm the change.
This beta version will not work on Mac OS X 10.9.5 or older.
