I accepted an update to OSX 10.11.3 this morning, and now I notice that my trackpad doesn't seem to be doing all it should. Has anyone else experienced this? For some reason I now cannot right-click by clicking with two fingers any more. (I could this morning.) And I don't appear to be able to shift between desktops with a there-fingered swipe anymore either. (Ditto) The trackpad will accept a single finger click as a left-click, and I can also scroll using a two-finger vertical swipe and navigate between Safari pages with a two-finger horizontal swipe, but as I say, I cannot two-finger click. The same thing is true on another user account, so it's not user-specific. I've checked System Prefs>Trackpad, and all the correct options are ticked. I have even changed the options, un-ticked them and re-set them back, but it makes no difference. I have also restarted the computer several times since the upgrade to no effect. I'm running a late 2010 MacBook Pro with 8GB memory installed. Has anyone any ideas please?
