I hate that option, when you are doing like survival games, and it it happen, it is like an auto-kill'
I have been having a similar but unrelated problem recently with my Laptop. While in Creative and Flying- Sticky Keys is a bit over eager to start up when I am trying to fly down
The shortcut for sticky keys (pres shift 5 times) can be disabled. Just press shift 5 times, and when the sticky keys pop up appears, besides the yes and no options there should be a link to configure sticky keys. Click that and you should see a checkbox to turn off the shortcut.
I fixed the sticky key problem but it seems in the process I have made it so that I can not double tap any keys. EDIT: fixed it.
Ok I heard a lot of that sticky key thing its so easy to fix who ever needs help please follow this. step 1:when the sticky key comes out when you press shift click yes or edit. step 2: If you click yes it might work If not click edit . step 3: when you click edit you will see the option click disable . NOTE: If this does not work please DONT blame me. Have fun in emc enjoy
But macs suck for playing Minecraft. Mac graphics run off opengl and so do minecraft graphics, so it makes it lag.
