Due to Apple's discontinuation of support for OpenGL graphics technology on Mac devices, support for the Mac OS version of Guild Wars 2 was discontinued on February 18th, 2021.
Accounts of users who played on the Mac client before that date will remain active. These users can continue to play on a supported Windows device, game streaming service, or via virtual machine or dual booting on an existing Mac device. We cannot, however, provide technical support or troubleshooting for these solutions.
For more information, please see the official announcement made on our forums.
