I've installed Forge for Minecraft 1.10.2 on MacOS X. The installer forge-1.10.2-12.18.0.2006-1.10.0-installer.jar ran successfully. There are now two profiles called "Forge" and "forge", differing in captialization. Both are set to run Minecraft 1.10.2. Minecraft loads as usual, but the Mods button doesn't show up. Below the Multiplayer button is Minecraft Realms, but telling from screenshots, Mods should be there. Is there anything I've missed?
