Cursor jumping when scrolling over/clicking links on my 2020 Macbook Pro 13"

Hey mikkel01,

We understand your cursor on your Mac is jumping when connected to a power adapter and hovering over links.

This can happen if you're using a third-party charging adapter. Given the steps you've taken to this point, we'd suggest checking to ensure you're using an Apple branded charger moving forward, if you're not already.

For more info on what you can do when this occurs, please review:

If your pointer is jumpy when you use a trackpad, Magic Trackpad, or Magic Mouse

We hope the above info helps out and thanks for using Apple Support Communities.

Take care!

mikkel01,

Thanks for the update!

If the issue isn't occurring in Safe Mode, this would indicate that the issue is likely caused by a login item.

For help with removing login items, go to  > System Preferences > Users & Groups > Login Items.

Unlock this page by tapping on the padlock and typing in your admin password. Once unlocked, tap on the " - " after selecting a login item to delete it. Restart your Mac afterward and boot it up normally.

For more info on these steps, please review:

Keep us posted on the results afterward.

Take care!

mikkel01,

If you're continuing experience this behavior even while using the Apple USB-C charger which was included, we'd suggest completing the rest of the steps at resource in our last post.

The very last step in that resource is to test things out in safe mode, as this will rule out any apps or processes which may be launching at startup that might interfere.

To access safe mode, hold the Shift key after turning on your Mac and hold it until you reach the login screen. For more info, check out:

How to use safe mode on your Mac

Keep us posted on the results.

Take care!

Instead of taking a more invasive step such as a clean install of macOS, you may want to try creating a new user account and testing things out further on it. To do so, go to  > System Preferences > Users & Groups and tap on the "+" in order to add a new account. You'll again need to unlock this page by tapping on the lockpad and entering your admin password.

If the issue doesn't occur in the new user account, you could always transfer your data to it and delete the old account. We'd only recommend doing a clean install of macOS if the issue is system-wide.

mikkel01,

We appreciate you letting us know that. If the issue is persisting after a clean install, there wouldn't be any other suggestions we could make at this point, as you've already ruled out any software issues with this step.

We'd recommend providing feedback on this behavior using the following link:
