Are you experiencing issues with connecting accessories to your Mac laptop computer? One common problem that many users face is a dark display when connecting a display to their Apple silicon-based Mac. In this article, we'll explore the steps you can take to troubleshoot and resolve this issue.

When you connect a display to your Mac laptop computer, it may ask you to allow the accessory (your display) to connect. This is a normal process, but if you don't allow it to connect, your display will remain dark. To resolve this issue, follow these steps:

1. If you can't restart your Mac, press and hold its power button for about 10 seconds to turn it off.

2. Press and hold the Option key to show the Detect Displays button, then click the button.

3. On Mac laptop computers, you can close the lid for a few seconds, then open the lid again.

If none of these steps work, try the following:

1. Disconnect the display from your Mac, then reconnect it.

2. Check if your external display is connected to a hub or dock. If so, connect it directly to a port on your Mac.

3. Ensure that your display's power cable and video cable are securely connected at both ends.

It may also be helpful to turn off the display first before trying to detect it again. To do this, go to the Apple menu (Apple logo) > System Settings (or System Preferences), then click Displays.

Some additional tips to keep in mind:

* Your Mac's specifications will determine how many external displays you can connect at once.

* The resolution and refresh rate of your external display may be limited by the video cable or adaptor used, as well as the resolution and refresh rate of other connected displays.

* If your display exceeds the maximum supported resolution or refresh rate, it may use a lower resolution or refresh rate or remain dark.

By following these steps and tips, you should be able to resolve any issues with connecting your external display to your Mac laptop computer. Remember to always check your Mac's specifications to ensure that it can support the number of displays you want to connect at once.

If you're still experiencing issues, you may want to consult Apple's support resources for more detailed troubleshooting steps or contact their customer support team for assistance.
