We are aware of the issues causing the 64bit EVE Online game client to freeze when initiating warp. The crash has been identified to occur on Mac OS X 10.12 (Sierra), 10.13 (High Sierra) and 10.14 (Mojave).
We are actively working on resolving the problem and will update you once new information is available. In the meantime, pilots encountering this problem are advised to switch to the 32bit game client through the launcher settings to continue playing EVE Online. You can find information on how to configure the EVE Online launcher here.
Thank you for your understanding and we apologize for any inconvenience it might have caused.
