Mouse clicks do not work in-game

[PeachCanario]

My mouse clicks only have effect when clicking on inventory and stuff like that, but when I get told to right-click on the lad or the woman when creating my character,it won't let me click. Scroll wheel click to rotate camera does work however. I have Mac OSX Yosemite and newest java

I have the same problem... I tried the Ender's Client, updated it so it was compatible with Java. Still didn't work

i believe there are some older topics talking about Mac issues.
If memory serves, a large part of the issues was due to color depth - make sure the color depth for your laptop/pc is set to 32 bits (you can google how to do this).

edit: the last thread on the topic seems to have been resolved by downgrading java. I can hardly condone it, but it might be worth checking whether that fixes the issue. I'd propose first trying the most recent version of java, though.
