Hello, I need urgent help. I used my HP Laserjet Pro 400 printer for a very long time now, and suddenly it simply stopped working. Instead of printing the document, I received a warning from Gatekeeper, which says, “HPDeviceMonitoring.framework” will damage your computer. Report Malware to Apple.” Did malware actually got into my computer, or is there something wrong with my printer?  hp printers troubleshooting mac

Recently users started complaining about an alarming pop-up message on their macOS Catalina or Mojave versions whenever they tried to use their HP printers. According to the vast majority of reports, the HP printer software simply stopped working, and it warns that it is malicious with the “hpPostProcessing.bundle” will damage your computer. Report Malware to Apple.”[1] The problem does not seem to be affecting older Mac versions, such as High Sierra.

As evident, many users were deeply concerned about this, not only because their HP printer is not working on Mac, but also because they suspected a virus might have broken into their devices. Indeed, there have been many instances when the “Will damage your computer” was related to malware infections. Basically, Gatekeeper recognizes all the unauthorized software and its components and flags it as potentially malicious.

So, has your HP printer software been infected? Most probably not. To connect your printer to your computer and in order to make it work correctly, you need to install software drivers. With new changes within macOS policy, a certificate that is used to sign the HP drivers has been withdrawn by the developer, hence the “HPDeviceMonitoring.framework will damage your computer. Report Malware to Apple” or a similar error shows up. According to a spokesperson from HP, the action was initiated “unintentionally”

We unintentionally revoked credentials on some older versions of Mac drivers. This caused a temporary disruption for those customers and we are working with Apple to restore the drivers. In the meantime, we recommend users experiencing this problem to uninstall the HP driver and use the native AirPrint driver to print to their printer

Now, while the problem is commonly related to the revoked driver certificate and all users suffering from it need to wait until HP released software drivers with a valid certificate, there is a way to fix HP printer problems on Macs. For that, you need to uninstall the current printer and use generic drivers for now.
