If you’re playing Dungeons & Dragons Online on an Apple desktop, you’re going to need to change clients. The existing MacOS client for the systems is being replaced with a new Wine-based client when a major update rolls around in October, which will mean the need to download and install a new client.

You know, just get the chore done with earlier.
