Mac wants to update my system to Sequoia 15.1 and they ran into a problem with my HP printer.

[GuitarJohn1]

I have an iMac that just tried to load the latest version of the operating system, which is Sequoia

15.1. They ran into a problem with my HP printer. This is the message they sent me:

Legacy System Extension - Existing Software on your system loaded a system extension signed by

"HP Inc." which, 

will be incompatible with a future version of MacOS. Contact the developer for

support.

Gaya1239 please stop saying: "Not to worry I will help you to get a resolution to resolve the issue.", when you don't even understand what we are talking about.

Apple has updated Mac OS to a new version making incompatible an extension made by HP.

All people involved in development of printers firmware and printer drivers, at HP, should know about this issue and should be already working to fix it by releasing an extension update. It shouldn't take months to do this.

and questions like "May I know your printer model and OS version" is pretty useless: obviously OS is Apple Mac OS 15.1 and this affects all HP printers or perhaps all HP printers older than one year.

Do you have an HP extension update ready in order to solve this problem? I guess not.

Your support is useless like your questions.

You din't even reply to the last posts giving you information about some of the involved models...

I am getting an indication that an extension that my system loaded a system extension signed by HP Inc which will be incompatible with a future version of macOS. I have an HP Officejet Pro 9015. I'm running macOS Sequoia 15.2. What do I need to do?
