Imac Legacy System Extension is not compatible with future version of macOS

[HarC1]

I turned on my computer and got the following message: "LEGACY SYSTEM EXTENSION."

Existing software on your system loaded a system extension signed by "HP Inc." which will be incompatible with a future macOS version. Contact the developer for support. Presently, I have macOS Sequoia 15.3.1

I would greatly appreciate your help in this matter.

Thank you for posting your query; I’m here to help by guiding you through steps to resolve this issue

Presently the printer supports mac OS 15

I suggest you download the latest drivers. Also, I suggest you wait for the updates to roll out for the current macOS.

Alternatively, you can use Air Print for printing. 

I hope these steps help resolve the issue
