Hi! When I click the computer or town hall and get my list of options, I can't change any of them. When I click one that says [true], it highlights and makes the click noise but does not change to [false] and vice-versa. Using 64-bit on mac. Thanks!!

One possibly very simple explanation is if you're trying to change the settings as soon as you've loaded the save, without the game clock running forward at all. If that's the case, let it run for a few sim-minutes, then try again.

By the way, when a setting says (True) or (False), in parentheses, that means it's being inherited from a broader category, for example you might be trying to change a Sim Option that's inherited from Caste or Town Options. When you explicitly choose a setting at that level, the setting will show as True or False, no parentheses.

In addition to the above, some options are select multiple and require the check box be used after you're done. Could also be a mod conflict.
