Got Rising Tide but how to go to basic BE?

I used instructions on this forum to get the MODS button in Civ:BE but when I got the Rising Tide expansion (from Mac App store), the MODS button disappeared from the new main menu, even though the MainMenu.xml still has the if/else code replaced. Any idea how to get the MODS button back in this expansion?

Alternatively, is there any way of reverting to basic BE (i.e. without the Rising Tide expansion) so I can use MODS on that?

Unfamiliar with how to revert with the App Store version. Steam shows DLC and expansions, which you can deselect before start-up.

Ah! Yes, thanks.
There's a DLC button in the menu on the App Store version that does that..
For some reason, I hadn't thought about that menu.
As is often the case, in retrospect it is obvious.

Thanks again.

Most welcome.

First off, make copies of the original files, so you have a back up.

It's not enough to change the MainMenu.xml in the original Front End. Open the package and make the modification described. Then go to Contents/Game Data/Assets/DLC/Expansion1/UI/Front End/MainMenu.xml. Look for the Mac_Ports code, and switch it as with the original Front End/MainMenu.xml. The button should be enabled then.
