I am using OS X El Capitan 10.11.6 (15G1217) on a MacBook Pro (Retina, 13-inch, Early 2015).

Sometimes when reading PDF's I notice I suddenly can not use the trackpad zoom feature anymore. It is not related to PDF's in general, as both in the apps Skim, Preview and Scapple it has stopped working.

If it had stopped working, multi-touch features such as Mission Control still work, suggesting the problem is not hardware.

When I disable and then re-enable the 'Zoom in or out' feature (cf. figure), it suddenly works again. How can I troubleshoot this problem? Disable and then re-enable to fix

  • I have the exact same issue but with Swipe back and forward gestures in Web browsers. No permanent solution so far. – stevyhacker Mar 19 at 19:33
  • @stevyhacker I think that by updating to macOS Sierra, the bug was solved. Currently I am using macOS Mojave and I don't experience this erratic trackpad behavior anymore. – Lucademicus Mar 20 at 6:14
  • I am on Mojave and I still experience it on Chrome a few times a month, glad it was solved for you. – stevyhacker Mar 20 at 14:04
