Using AirPods once your iPhone has forgotten about them is an easy procedure. If you have set your AirPods to “Forget This Device“, your iPhone will not be able to find them again until you reset them.

You may factory reset your AirPods by opening the case’s lid and pressing (holding) the setup button. Do so until the status light alternates between amber and white, a process that should take around 15 seconds. This will reset the AirPods.

Follow the standard method for reconnecting your AirPods again.

In case, you have any other device, such as Sony Headphones, you can reset the headphones manufacturer’s guide. Each manufacturer and each headphone type has a different way of being reset, so it is better to check the guide for further information.

Pro Tip: Method 1 is not too complicated, but it does need some research on how to reset each unique Bluetooth device. However, un-forgetting a Bluetooth device using this approach is the most reliable way to do it on iOS.

Resetting the iPhone’s network settings is the second most reliable method for getting it to un-forget a forgotten Bluetooth device. Resetting an iPhone’s network settings will wipe off all Wi-Fi networks (and their passwords), cellular data, and Virtual Private Networking (VPN) connections.

Network resets consist of the following:

  • When you reset your network settings, you will lose access to any saved networks as well as any passwords you may have used to access Wi-Fi networks. It will also reset cellular data settings and reset any data calculators that you may have used earlier.
  • You will lose access to your VPN configurations, including your username, password, server address, and VPN type.
  • You will lose access to all your Bluetooth devices (paired).
  • If wiping your iPhone’s network settings and losing access to any saved Wi-Fi or VPN networks is something you are comfortable with, then go ahead.

Resetting your iPhone’s network settings is one way to un-forget a forgotten Bluetooth accessory.

Pro Tip: Method #2 is the most involved, and you should keep in mind that it will erase all of your passwords and network settings.

Method #3: Restarting the iPhone

Restarting your iPhone is the easiest option. The potential ease of use make this approach attractive. However, in numerous cases, this does not make any difference which is why the other solutions were mentioned first.

How to Unforget A Bluetooth Device on MacOS?

macOS Bluetooth Interface | Apple Support

When you forget a device on Mac, you are erasing all of its connection information. To un-forget it, just repeat the initial connection procedure.

It is usually not too difficult to get the Bluetooth device back online. To connect a Bluetooth device with your Mac, you need to switch on Bluetooth on your computer, put the device into pairing mode, and then choose it from your Mac’s Bluetooth menu.

Once the device has been re-paired, your Mac will automatically rebuild the necessary data and permissions to establish a connection.

Important: Your Apple Mac has a file named “Bluetooth.plist” where you may configure your Bluetooth settings. When this file is complete with all the necessary information, it can build fast and automated connections to all the devices it has rights for; but, when a device is forgotten, it loses this information and must be updated again.

If the Bluetooth menu fails to establish a connection, or if the device vanishes without your intervention, there is probably a deeper problem that needs to be investigated.

Perform SMC and PRAM Reset

Your Mac’s System Management Controller (SMC) and Parameter Random Access Memory (PRAM) are responsible for storing and managing data and procedures for a number of critical pieces of hardware. Everything from the track pad and keyboard to the batteries and fans to the camera and Wi-Fi and even Bluetooth functionality is included.

Apple silicon MacBooks do not have SMC or PRAM reset. Simply powering off the MacBook then turning it back on is the most you can do here.

The SMC and PRAM resets may assist in certain situations.

Follow this procedure to reset SMC:

  1. Shut down your Mac.
  2. Press and hold the Shift + Control + Option keys on the left side of the keyboard and the power button at the same time.
  3. Hold these keys and the power button for 10 seconds.
  4. Release all keys.
  5. Press the power button again to turn on your Mac.

In case your MAC has removable batteries, you can simply shutdown the mac, remove the battery, press the power button for 10 seconds, and reinsert the battery to perform an SMC reset.

Follow this procedure to reset PRAM:

  1. Shut down your Mac.
  2. Press the power button to turn on your Mac.
  3. Press and hold the Command + Option + P + R keys immediately after you hear the startup sound.
  4. Hold these keys down until your Mac restarts and you hear the startup sound for a second time.
  5. Release the keys.

Keep in mind that if your Mac device has Apple T2 Security Chip, you will need to Press and hold the power button for at least 10 seconds, and then release it.

Resetting the SMC and PRAM is a fast and easy way to fix many problems. After this is done, you may try reconnecting all your devices (by hand the first time), and the problem will be fixed.

Bluetooth Module Reset Procedure

If resetting the SMC and PRAM did not fix the problem, or your device does not have SMC and PRAM support, you may try resetting the Bluetooth module. Disconnecting and re-pairing the Bluetooth module is normally unnecessary, particularly if you specifically instructed the computer to forget the device.

Please be aware that this will also delete any previously setup devices that were not accidentally left behind. However, there is nothing to worry about if the Bluetooth devices have been forgotten. The Bluetooth.plist file may be updated by manually re-pairing the devices to the Mac for the first time.

Fixing Other Frequent Mac Bluetooth Problems

Some of the basic solutions to remembering your gadgets are listed below:

  • It may be as simple as restarting your computer or other device. Although it is a cliché, it gets the job done. Try disabling Bluetooth and then re-enabling it on both your Mac and your device.
  • Macs are said to be able to handle no more than 7 devices at once, but in practice, even 2 or 3 might be too many, especially if one of them has a high data consumption rate. Try disconnecting or forgetting any devices that are not in use to see if it solves the problem.
  • Keep your Mac up-to-date. Apple is constantly updating its Bluetooth connection software and procedures to accommodate new developments in the industry. It is conceivable that all you need is the latest software update for your PC;
