Best Practices for Device Connection
Move a MacBook with a Plugged-In Mouse
Some users question whether they should unplug the mouse from a MacBook before moving it. While it is possible to leave the mouse plugged in, it is advisable to unplug it when moving the MacBook to avoid the risk of damaging the port if the mouse gets caught on something.
General Recommendations
In most cases, it is best to leave the mouse plugged in. Plugging and unplugging the mouse while the computer is off reduces the risk of wear and tear on the mouse and its cable. Moreover, the computer checks for connected devices at startup, so the mouse will be discovered and ready for use.
Power-Up Issues
Some laptops are designed to provide power to USB ports even when the computer is off. If you plug your mouse into one of these ports and the laptop is not connected to its charger, the mouse can drain the laptop’s battery over time.
Conclusion

However, it is generally safer and more convenient to leave the mouse plugged in, especially when the computer is on or during regular use. Adhering to these best practices will ensure that your computer and mouse operate smoothly and efficiently.
