After Sierra Update:Trackpad Not Disabling with Magic Mouse Connected

I had this problem and the workaround did not resolve it.

Now I have installed 10.12.2 and the problem has changed. When I boot the computer the setting "Ignore built-in trackpad when mouse or wireless trackpad is present" is not checked. I check it and it works but on the next boot it is not checked and does not work. I also see the check does not remain in the check box after closing Accessibility but the trackpad remains inoperative. But upon reboot the check is not present and the trackpad works.

For some reason I can not enter a bug report to Apple any more. Is there anyone who can submit this to them?

Thanks,

Rick

I have a Magic Mouse 2 and this does not fix the problem. In fact even switching to a different mouse does not solve the problem. The problem is that the state of the configuration is not remembered after a system re-boot.

Until Apple fixes this problem with an OS-X update, there's nothing you can do other than NOT turn your computer off if you want the trackpad to be disabled.

I do believe there was a minor fix to this problem though. When I first noticed it, it was necessary to reboot in order to activate the "ignore trackpad..." check. Now, at least on my MBA with Sierra, the ignore feature can be turned on or off without rebooting.

I think Apple users who don't want the trackpad active are a very small minority OS-X users. IF I didn't rest my palms on the trackpad while typing, I would prefer it to be active all the time myself . But I don't and when I'm typing, my palm brushes the trackpad, send the cursor to TIMBUKTU.

I have the same problem and the fix suggested by blueeos did not work for me. Every time when I shutdown and reboot or restart the computer, the trackpad comes back even when the options is checked. Now I have just updated to 10.12.3 (the latest update), the option gets wiped out after you close System Preference. Apple, please fix it properly and don't make things worse. I have sent a feedback to Apple but I doubt this will be taken care of in the soon future. Note: I have been using a Magic mouse 2 for many years and this only happen after I upgraded to Sierra.

I have the opposite problem with Sierra "Ignore built-in trackpad when mouse or wireless trackpad is present" option.
I have Logitech MX2 Anywhere mouse and the trackpad remains stiff/deactivated when I tick that option even though my mouse and universal receiver are not connected!

I am not sure if people have said this already, and I am just rephrasing the previous replies, but I'm gonna put it in words that I understand and hopefully others do as well.

So, when I am using my computer and I reboot, the trackpad gets re-enabled. I always have to go back into the System Preferences and click the "Ignore built-in trackpad when mouse or wireless trackpad is present" every time, even when the setting was enabled before I rebooted my computer. Meaning, my MacBook Pro always automatically disables that setting, even though I have another mouse connected.

I use a Logitech M185 Wireless Mouse and I always have it connected when I reboot my Mac, as well as have it always connected when I am using my Mac. But, it is very annoying to always have to go into the Settings and keep clicking that box after every restart/shutdown of my MacBook Pro.

I currently use a MacBook Pro (13-inch, Mid 2012) with macOS Sierra 10.12.3 installed.

Is there any fix or way to either permanently disable the trackpad when another mouse is connected, or to use the Terminal to tell the computer to keep that setting always active? Because I am really tired of having to go into the Settings and click that box, especially since it takes my computer like 30 seconds to load up the System Preferences Pane after reboot.

I might have bumped into a fix by accident. You may try the following.

First, check or uncheck the box "Ignore built in trackpad ..." to disable or leave trackpad enabled while mouse is connected as you wish. Try and make sure it is doing what you want. Then at the bottom left of the Accessibility window, check the box to 'Show Accessibility status in menu bar'. Close System Preference. Now reboot your system. This fixed my problem and now even if I uncheck the box 'Show Accessibility status in menu bar', the Ignore built in trackpad setting that I had before is still being remembered after shutdown and reboots.

I have 15" mid-2012 Retina MBP, and my Ignore trackpad... settings are not saved across shutdown/reboot.

There is nothing that I can do that appears to alter this behaviour, and it is VERY ANNOYING.

macOS Sierra 10.12.3 (but this behaviour has been there since 10.12)

It does not seem to matter whether I check the "Ignore built-in trackpad when mouse or wireless trackpad is present" button in the accessibility settings or not.

Is there a way to completely disable the trackpad? I never use it....ever. I can't type or do anything with this without it completely screwing up what I am typing. If I simply graze the thing, my cursor shifts to a new position. Really annoying.

This issue is only second to the escape key not having a physical button, and I often graze it as well, kicking me out of whatever I am doing at the time. I realize this is a different issue, but it is related somewhat.

I thought I found a way to get it to work... by clicking the "Enable Mouse Keys", and then checking the "Ignore built-in track pad when mouse or wireless track pad is present"button there in the options for this.

It disabled the mouse pad. Yay!!...but it also made typing anything a nightmare...BOOO!!!

Still an issue.

I'm not using Magic Mouse, but I wired USB mouse and am having the same issue since installing Sierra.

I have the box checked, but I have to go in and uncheck it then recheck it.

I have to use a mouse all the time because my trackpad goes haywire and I have not been able to find a fix for it. It moves on its own and opens stuff on its own.

You need Magic mouse 2 and or magic trackpad 2 for El Capitan and Sierra. They were designed for these OS's. I have yet to read of any other mouse having the drivers to work fully with these OS's, though I have been away for a month so I could have missed something.

Yes, guilty. I was looking at your additional information. I, too, like to have both connected and like you, find the 'ignore mouse' option very helpful. But I am avoiding Sierra for the first few weeks so as to allow others to find the bugs and then do the updates. The 'reinstall Sierra' may help and if you go this route, do come back and tell us the result.
