[06/02] Black screen when loading NXT on Mac
We are aware that some players are encountering a black screen when trying to load the NXT game client on Mac OS. Sometimes a small black box may also appear when launching the client. We are working on getting this resolved as quickly as possible.
In the meantime try using the Legacy version of the game client, which is available from the downloads page on the RuneScape website.
You may find that you are able to launch the NXT game client after restarting your system. However, if you close the game client at all then you may need to restart your system again.
