Macbook Trackpad not allowing dragging

Hi there, Steve,

Thanks for visiting the Apple Support Communities. We understand the trackpad on your MacBook isn't behaving as expected and will not make text selections or drag items, among other functions. We're happy to help!

Based on what you've described, we would use the following Apple Support articles to get information, check settings, and troubleshoot:

If the pointer doesn’t move when using the trackpad with Mac - Apple Support

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

Change Trackpad preferences on Mac - Apple Support

MacBook Pro trackpad - Apple Support

Use Multi-Touch gestures on your Mac - Apple Support

Have a great day.
