I have a Mac. I have unplugged every mouse that you can connect, including the lazer mouse. The only mouse that's left is the trackpad that was built into the computer. It started getting worse. I didn't touch any thing in my computer, but the cursor would twitch back and forth. Then, at random times, it would move super fast in a random direction. As you can see, this would make minecraft impossible/really hard to play. So, if you've seen me bobbing and moving my head like crazy in game, now you know why. :/ I tried cleaning the trackpad, but I think that just makes it worse.Any suggestions to fix this? (I don't want to buy a new computer )
