Trackpad not working after keyboard cleaning.
This morning I lightly wiped the keyboard, trackpad, and palm rest area with a sanitizing wipe - something I've done many times over the years.
My trackpad now does not work properly. The cursor skips across the screen in small steps when trying to use the trackpad, and will drift when left untouched.
I have tried resetting NVRAM (cmd opt p r) and removing the Finder preference files, but I get the same behavior - this is all I could find that was self-help related...
I removed the trackpad from the frame and inspected the connector cable and wiped all corners / edges of the frame and trackpad - still no go. Same results as before.
Keyboard works fine, as does an external mouse.
AppleCare is now expired (must be only a couple days outside of warranty)...
Before I spend $90 on a replacement trackpad, I'm looking for a way to confirm that the trackpad is indeed the issue.
How long have you waited since you cleaned it? I have this same issue when I wipe my computer down with water or any other computer product. The issues is that excess water gets along the sides of the trackpad, and similar to using your phone underwater, it thinks you are constantly touching the trackpad in every corner. I usually let the trackpad try out, but somethings it helps if you take a piece of paper, stick the edge in between the trackpad and the palm rest, and run it around the sides of the trackpad gently. You might see the paper gets wet. If it does get wet, just use another corner and go around again. This should work. If the problem still occurs, then you might want to take out your battery and see if there is any water under the trackpad. If nothing works, let it sit for a day or two, that normally will fix the problem. In the unlikely case that you did damage your trackpad, you may need to replace it. I have had this same issue though on MacBooks from 2006, to MacBook Pros from 2013, and either drying the sides with paper, or letting it sit always works.
Hope this Helps
