HP Printer Driver Certificate Issue

HP Printer Driver Certificate Issue. Fix Error Message "(FileName)" Will Damage Your Computer"

HP (short for Hewlett-Packard) is a well know manufacturer of software, hardware, and computer services. Their developed printers are one of the most popular in the world. HP states that their printers are highly reliable, and the technology used is very advanced. It changes from time to time to ensure better performance and quality. Unfortunately, users of HP printers have been experiencing quite worrying problems.

On the 19th of October 2020, Apple released routine updates to XProtect and MRT security tools. These updates are released around every two weeks. If your Mac Software Updates are set to "Install system data files and security updates," the security updates were automatically downloaded and installed. After these updates, many users have run into problems with their Mac. Due to the new updates, MRT started crashing and automatically restarting, which affected Mac's overall performance.

HP Printer Driver Certificate Issue

On the 23rd of October 2020, Mac users have started reporting an issue related to their HP printers. When trying to use the printer, a message popped up on the screen, implying that the software is malicious and stating that it'll damage the computer. This error occurred not only when trying to print something but from other services and frameworks like scanning. Depending on the reason you were trying to use your HP printer, various error messages started appearing on the screen.

It appears that only Catalina and Mojave operating systems were affected by this issue. The problems also were frequent with older HP printers. So far, there are no reports of the problem from macOS High Sierra and older versions of macOS users. Catalina users experienced crashing reports when macOS force-crashed HP software because the code signature was invalid.

Fortunately, the cause of this problem is not within XProtect, which checks for signatures of known malware or MRT, whose purpose is to remove malware. The error message appears when the Gatekeeper, which ensures that only trusted software runs on your Mac, check the software being launched and finds a fatal signature problem, therefore, not allowing you to run the software. Gatekeeper finds the signature problem and displays the alert or crashes the app. Depending on where the signature is failing, the error messages can variate. When an error message appears stating, "****** will damage your computer," and Mac operating system refuses to run the printer, it means that macOS checked the signature on your HP printer software and found a problem within.

After the signature check on some of the affected software, it was revealed that the signing certificate had been revoked. HP has sent a response to The Register stating that they "unintentionally revoked credentials" and that they are "working with Apple to restore the drivers."

On the night of 24-25ft of October 2020, Apple PKI (Public Key Infrastructure) withdrew the HP certificate's revocation. HP printer software should now work normally again.

Even though the certificate was unrevoked, Mac users are still reporting issues that appear to be related to the HP signature errors. If you're still experiencing problems with your HP printer, keep reading.
