Legacy System Extension

[FlyEagles1]

Received boxed warning on Mac desktop with Sequoia 15.3...Legacy System Extension...Existing software on your system loaded a software extension signed by "Legacy Developer: Hp" which will be incompatible with a future version of MacOS. Contact the developer for support.

Called a Sponsored number that I thought was Hp customer support, but turned out to be third party.

I was informed that no automatic updates were being downloaded to my computer!

What should be my next step?

@FlyEagles1, Welcome to the HP Support Community! 

Thanks for reaching out about your query regarding Legacy System Extension!  
We're thrilled to have the opportunity to assist you and provide a solution.

It sounds like you're dealing with a legacy HP printer driver issue on macOS Sequoia 15.3. Here’s what you should do next:

1. Verify HP’s Official Support Options

• Go to HP’s official support website
• Search for your printer model (HP ENVY 5660 e-All-in-One Printer) and check for updated drivers or software.

2. Check for HP Easy Start

• HP provides HP Easy Start, an official tool that installs the latest drivers for macOS.
• Download it from here.
• If HP Easy Start does not detect your printer, macOS may have built-in AirPrint support.

3. Remove the Old HP Software

Since macOS warns about "Legacy System Extension," you may need to uninstall outdated HP software:

• Open Finder > Applications
• Look for any HP-related software and move it to the Trash
• Restart your Mac

4. Use AirPrint (Mac’s Built-in Driver)

If HP has no updated drivers for your model, use AirPrint:

• Go to System Settings > Printers & Scanners
• Select your HP printer and click Remove (-)
• Click Add (+) > Select Printer
• Under "Use," choose AirPrint (instead of the HP driver)

5. Check System Preferences for Updates

• Go to System Settings > General > Software Update
• Ensure that macOS and printer drivers are updated.

6. Enable Automatic Updates for HP Software

• Go to System Settings > Software Update
• Check for any pending updates related to HP.

If your printer still doesn't work after these steps, let me know what issues you're facing, and I can guide you further! 🚀

Take care, and have an amazing day!
