Re: Firmware update no go on AirPods
You may need the latest software update available on your Mac or device in order for the firmware to update.
Eg: What's new in the updates for macOS Sequoia - Apple Support says MacOS 15.4
If updating: Please remember it is always wise to back-up your Mac before updating MacOS
About firmware updates for AirPods - Apple Support
Eg: says:
Update your AirPods or AirPods Pro firmware
- Make sure that your iPhone, iPad, or Mac is updated to the latest version of iOS, iPadOS, or macOS, and that Bluetooth is on.
- Make sure that your AirPods are connected via Bluetooth to your iPhone, iPad, or Mac.
- Connect your iPhone, iPad, or Mac to Wi-Fi.
- Connect your charging case to power.
- Put your AirPods in their charging case and close the lid. Keep the lid of the charging case closed, and keep your AirPods in Bluetooth range of your iPhone, iPad, or Mac.
- Wait at least 30 minutes for the firmware to update.
- Open the lid of the charging case to reconnect your AirPods to your iPhone, iPad, or Mac.
- Check the firmware version again.
If you still can’t update your firmware, reset your AirPods, then try to update your firmware again.

Re: The other issue is I can’t pair all my devises to the AirPods 4 and then select them to be turned on as I move from one computer to another as needed.
You may want to check you did not accidentally prevent switching in Settings:
"Prevent AirPods from automatically switching to your iPhone, iPad, or Mac
- iPhone or iPad: Go to Settings
> Bluetooth, then tap
next to the name of your AirPods. Tap Connect to this [device], then tap “When last connected to this [device].” - Mac: Choose Apple menu
> System Settings, click Bluetooth
in the sidebar, then click
next to the name of your AirPods. Below Connect to This Mac, choose “When last connected to this Mac.” "
