How to Solve the Sidecar ‘Device Timed Out’ Error on Your iPad?

Share This:

Sidecar is a great feature introduced by Apple that allows you to use your iPad as a second display for your Mac. It's a handy tool for those who need extra screen space or want to extend their workspace. However, like any technology, it's not without its glitches. One common issue that users may encounter is the “Device Timed Out” error message when trying to connect their iPad to their Mac using Sidecar. In this article, we will explore some troubleshooting steps to fix this problem and get Sidecar up and running smoothly.

The first thing you need to check is whether Bluetooth and Wi-Fi are enabled on both your Mac and iPad. Sidecar requires both of these connections to work properly. To enable Bluetooth, go to the Bluetooth settings on your iPad and Mac and make sure they are turned on. Similarly, ensure that Wi-Fi is enabled on both devices as well.

Another important setting to check is Handoff. Handoff allows for seamless integration between your Mac and iPad and is necessary for Sidecar to function. On your Mac, go to the Apple menu, then System Preferences, and click on General. Towards the bottom of the window, you will find a checkbox that says “Allow Handoff between this Mac and your iCloud devices.” Make sure this option is selected. On your iPad, go to Settings, then General, and look for the Handoff option. Ensure that it is enabled.

If the above steps do not resolve the issue, try restarting both your Mac and iPad. Sometimes, a simple restart can fix minor glitches and get Sidecar working again. After restarting, attempt to connect your devices using Sidecar and see if the error message persists.

It's also crucial to keep your Mac and iPad up to date with the latest software updates. Apple frequently releases updates that address bugs and improve performance. Check for updates on both devices and install any available updates. This can potentially resolve the “Device Timed Out” error.

Another troubleshooting step is to turn on iCloud Keychain on both your Mac and iPad. iCloud Keychain securely stores your passwords, credit card information, and other sensitive data. Enabling it can help in establishing a secure connection between your devices and fix any connectivity issues.

If none of the above solutions work, you can try manually finding the iPad with Bluetooth from your Mac. To do this, go to the Bluetooth settings on your Mac and click on “Show Bluetooth in menu bar.” Then, click on the Bluetooth icon in the menu bar and select your iPad from the list of devices. This can sometimes bypass any connection issues and allow you to use Sidecar without encountering the “Device Timed Out” error.

In some cases, network settings can interfere with Sidecar's functionality. If you are using Sidecar with a university network, for example, it may not work as most universities set up their networks to prevent devices from communicating with each other. If you suspect this may be the issue, try using Sidecar on a different network, such as a home or public Wi-Fi network, and see if the error message persists.

Lastly, make sure your iPad is unlocked when attempting to use Sidecar. If your iPad is locked, you won't be able to connect to it. Simply unlock your iPad and try connecting again.

The “Device Timed Out” error message when using Sidecar on your Mac and iPad can be frustrating. However, by following the troubleshooting steps outlined above, you should be able to resolve the issue and enjoy the benefits of using Sidecar as intended. Remember to check Bluetooth and Wi-Fi settings, enable Handoff, restart your devices, update system software, turn on iCloud Keychain, manually find the iPad with Bluetooth, and ensure your iPad is unlocked. With these steps, you can overcome the “Device Timed Out” error and take advantage of Sidecar's functionality.

By following these troubleshooting steps, you should be able to identify and resolve the issue preventing Sidecar from connecting to your iPad.

Why is Sidecar Unable to Connect?

There can be several reasons why Sidecar is unable to connect. Here are some possible causes:

1. Network Restrictions: If you are using Sidecar on a university or corporate network, it may not work due to network restrictions. These networks are often configured to block communication between devices, which can prevent Sidecar from establishing a connection.

2. iCloud Sign-in Issues: Sidecar relies on iCloud to establish a connection between your Mac and iPad. If there are any issues with your iCloud account, such as sign-in problems or syncing errors, it can prevent Sidecar from connecting.

3. Network Settings: Sometimes, network settings on your Mac or iPad can interfere with Sidecar. Resetting the network settings on both devices can help to resolve any configuration issues that may be causing the connection problem.

4. Software Compatibility: Sidecar requires both your Mac and iPad to be running compatible versions of macOS and iPadOS respectively. If either device is running an outdated or incompatible software version, it can cause connection issues.

To troubleshoot and resolve the Sidecar connection problem, you can try the following steps:

1. Sign out of iCloud: On your Mac and iPad, sign out of your iCloud account. This can be done in the iCloud settings on both devices.

2. Reset Network Settings: On your Mac and iPad, go to the settings and find the option to reset network settings. This will reset all network configurations, including Wi-Fi and Bluetooth connections.

3. Restart Devices: After resetting the network settings, restart both your Mac and iPad. This can help to clear any temporary glitches and ensure a fresh start.

4. Sign in to iCloud: Once the devices have restarted, sign in to your iCloud account again on both your Mac and iPad. Make sure to use the same iCloud account on both devices.

If these steps do not resolve the issue, it is recommended to check for any software updates for both your Mac and iPad. Installing the latest updates can often fix compatibility issues and improve the performance of Sidecar.

It's important to note that if you are using Sidecar on a university network, it may not work due to network restrictions. In such cases, you may need to use Sidecar on a different network or consult with your network administrator for further assistance.

How Do You Stop Your iPad from Locking the Sidecar?

To prevent your iPad from automatically locking when using Sidecar, you can adjust the Auto-Lock settings. Here's a step-by-step guide on how to do it:

1. On your iPad, go to the Settings app. You can find it on your home screen.
2. Scroll down and tap on “Display & Brightness”. This option should be available in the left-hand menu.
3. Look for the “Auto-Lock” option and tap on it. It is usually located near the top of the screen.
4. In the Auto-Lock menu, you will see several options for the time interval before your iPad automatically locks. By default, it is set to a few minutes (e.g., 2 minutes or 5 minutes).
5. To prevent the iPad from locking while using Sidecar, select the option “Never”. This will keep your screen awake indefinitely until you manually lock it or change the Auto-Lock setting back to a time interval.
6. Once you've selected “Never”, exit the Settings app. Your iPad will now remain unlocked as long as it is connected to Sidecar, allowing you to use the feature without interruptions.

By following these steps, you can ensure that your iPad doesn't lock while using Sidecar, providing a more convenient and uninterrupted experience.
