Latest MacOS update says HP "Legacy System extensions" will be incompatible with future macOS

[lmcrowd3r]

My Mac is running Sequoia 15.3; just installed this morning. I got two notices, both titled LEGACY SYSTEM EXTENSIONS and saying basically the same thing: Existing software on your system loaded a system extension signed by “Hewlett Packard” which will be incompatible with a future version of macOS. Contact the developer for support.

Anybody out there got any ideas? I can't find how to contact HP directly.

Hi @lmcrowd3r, Welcome to HP Support Community. 

Thank you for posting your query, I will be glad to help you. 
The "LEGACY SYSTEM EXTENSIONS" notice you're encountering indicates that the current HP printer drivers on your Mac are using system extensions that will become incompatible with future macOS versions.

Please follow these steps, 

Download the Latest Driver:

• Visit the HP Color LaserJet Pro MFP M277dw Software and Driver Downloads page.
• Select your operating system.
• Download the latest available driver or software package.

Install the Driver:

• Open the downloaded file and follow the on-screen instructions to install the new driver.
• After installation, restart your Mac to ensure the new driver is properly integrated. 
   

If you don't see your OS or versions, please follow this document - https://support.hp.com/in-en/document/ish_6966654-6966703-16

I hope this helps. 

Take care and have a good day.

This only helps if I still had the printer. I stopped using my hp printer and bought a different brand. So I want to know how to remove my hp system extensions. Also, are all the system extensions starting with hp_ save to remove? Here are my system extensions:

hp_Inkjet1_io_enabler.kext
hp_Inkjet3_io_enabler.kext
hp_Inkjet4_io_enabler.kext
hp_Inkjet5_io_enabler.kext
hp_Inkjet8_io_enabler.kext
hp_Inkjet_io_enabler.kext

Followed the link. The OS systems listed are old. What does one do with Sequoia 13.5.2 operating system on a MAC if one gets the message that some system extensions aren't compatible with current versions of macOS or won't be compatible with a future version of mac OS? 

HP seems a big enough company to be keeping up with both MAC and Windows software updates.

Following link as well since I updated to iOS Sequoia 15.3.2 earlier this week and received the same OS message.  My HP OfficeJet Pro 9130e Series' firmware is automatically updated (reconfirmed via Control Panel today) and System Settings shows "HP OfficeJet Pro 9130e Series-AirPrint" in the Kind field.  What do I need to do to ensure future versions of macOS will be compatible?

Hello Max3Aj,

I received the same message today when I updated my MacOS.

I have a HP Photosmart D110 series printer. Can you please tell me if there is a Driver available to download for this printer?

I recall having issues finding a driver when I got this MacBook, but was able to find one that was compatible with my printer.

Thanks!
