A bug in OS X El Capitan causes issues with Apple’s new Magic Trackpad 2. As a result of these Magic Trackpad issues, OS X intermittently doesn’t register clicks.
While I was battling Bluetooth connectivity issues with Apple’s Wireless Keyboard and Magic Trackpad, I thought the problem might be hardware-related. When Apple released the new Magic Keyboard and Magic Trackpad 2, I decided to upgrade, hoping it would fix the problem. As we know now, the hardware didn’t cause the issue but a bug in OS X that Apple has fixed meanwhile.

Sometime during the OS X El Capitan 10.11.X beta cycle, I started noticing the following intermittent issues:
I was hoping that the GA release of 10.11.4 would fix the problem, but it didn’t. So I called Apple Support to see if they had heard about this issue at all.
I had low expectations because front-line support usually can’t help with these type of problems. I guess my tone of voice and attitude already signaled that because neither the guy who picked up nor the senior advisor I was transferred to made much of an effort to understand the problem.
Their recommendation was to try to reproduce the problem with a different user account and, if need be, to re-install OS X. Even though that approach makes sense to isolate the problem, I don’t get paid by Apple to do their quality assurance and didn’t want to invest that time.
I shouldn’t jump to conclusions but the following symptoms, in my humble opinion, point to a bug in OS X’s input event handling and not to an issue with my user profile or configuration:
It just seems like somewhere along the event handling line, the “physical” click on the Magic Trackpad 2 does not get forwarded to OS X or the application. To me, that just has bug written all over it.
A workaround for this problem is to switch applications temporarily. For instance, if Finder doesn’t register clicks I would switch to Safari and then immediately back to Finder. After the switch, click events in Finder register again. After hours or sometimes even days later, the problem would occur again.
When I blog about issues like this one, I usually have a solution or idea of how to solve the problem. Not in this case! But before I start investing hours and potentially days of troubleshooting, I’d like to find out if there are other affected users out there. If I’m the only one with this issue, I’ll perform the following troubleshooting steps to narrow down the issue:
But I guess that I’m not alone, and so I’ll file a bug report with Apple and then patiently wait for them to fix the problem in one of the next releases.
It turned out a bug in OS X caused the issue, and Apple has since fixed it. As of this writing, I use macOS Sierra, and I still experience the occasional problem with Apple’s peripheral devices. If you are affected and are on an older version of OS X, I would recommend upgrading to the latest version of macOS.
