Cursor moves randomly when typing in Pages and Mail

Cursor moves randomly when typing in Pages and Mail. I've checked keyboard and trackpad in System Preferences but I can't find anything to change and stop this.

Limited to these two apps only?


A swollen battery can lead to this erractic behavior but it would be universal.


To trouble shoot further you can:


Try a SafeBoot  https://support.apple.com/en-us/HT201262

Takes noticeable longer to get to the login screen, does a 5-10 minute disk repair before it fully boots up, and certain system caches get cleared and rebuilt, including dynamic loader cache, etc.

This test will tell you if third party interference; extensions etc are not loaded in safe boot mode.


Test issue in another user (or guest user) account  https://support.apple.com/en-us/HT2044

This will tell you if it a universal issue or isolated to your user/admin account.
