Recently my uMBP's trackpad has been essentially unusable. Multitouch no longer works. It barely registers physical clicks. Tap to click doesn't work. It tracks extremely poorly. I can't even do two-finger scroll. Right click also no longer works. First of all, is this a common problem and is there a fix? And secondly, if I have to bring it in, I'm a bit worried as it'll be the first Mac I've ever brought in for replacement/service. I haven't had issues before. The thing is, I DO have some pirated software installed. I know there's a lot of taboo surrounding that, but to each his own. That's not the topic here. I was wondering if that was going to be an issue when I attempt to bring in the laptop. Please, no lectures!
