Trackpadembedded on each model MacBook has many flush functions and is much more complex than the classic touchpad from laptops with Windows. However, the moment we have a Magic Mouse connected to Mac, the trackpad may become uncomfortable. It can be touched involuntarily when you type or you could press it unintentionally. Moreover, the built-in trackpad loses its usefulness when we have connected one trackpad wireless.
The best practice is to we disable the Trackpad when the mouse is connected la MacBook or iMac.
How to set the trackpad to turn off automatically when the mouse is connected to Mac
1. We open “System Preferences"And we go to"Accessibility"
2. In "Accessibility"We go to the bar on the left at"Mouse & Trackpad" Yes tick option"Ignore built-in trackpad or mouse When wireless trackpad is present".
After checking this option, the built-in trackpad will automatically turn off when on Mac a wireless mouse or trackpad is connected wirelessly or wired.
