SolvedROTMG 17.3 Client for Mac

Download the mod selector zip and click the folder that has hacked clients in it. 1 is fullscreen, the other has no fullscreen. Both have several hacks but none have lava walls. Those prehacked clients are for mac and linux users who can't use the mod selector and don't know how to add the code manually.

I'll make a mac version of the modselector when i'll be more familiar with XCode

Not hexed or it would say 17.2 HEXED to 17.3 or just HEXED in the title somewhere. Or you could try it and find out instead of asking...

The fullscreen one has everything, the none fullscreen one has everything minus fullscreen and spammable notifications. Both have 30% auto nexus.
Neither have lava walls because it can't be turned off ingame and could get you killed or screw you over in abyss trooms.
They're not hexed and hexing hasn't been possible for the last 2 releases. You can see the new sword with the clients.

The fullscreen one is not actually fullscreen in a realm for me, so sad D:

Open your client, press the O key to open the options menu, click the graphics tab, look where it says hardware acceleration and turn it off. Now close the client and reopen it. Fullscreen will work in realms and everywhere now. Don't turn hardware acceleration back on or fullscreen will break again.

The first words at the top of the mod selector 1st post tell you to do that if you want fullscreen to work.
