Owners of printers from the Hewlett-Packard brand currently have problems when using the device on a Mac: The manufacturer’s official applications are failing in a row because the operating system seems to mistake them for malware.

This includes, for example, the widely used HP Utility (HP printing tool), with which the printer settings can be made, and HP frameworks for monitoring the printer running in the background. macOS indicates when the programs are started (or restarted) that the applications could “damage the computer”. This may also make printing impossible.

Certificate has apparently been withdrawn The reason for the error message is apparently the fact that there is a problem with the security certificate of the HP applications. macOS is apparently notified that this has been withdrawn. However, not all versions of the operating system are affected because they use different databases; High Sierra (10. 13) and macOS Versions lower than this work normally.

The problems do not affect the printing functions in macOS itself, which can be accessed via the system settings or the individual programs – however, many users also install the HP utility. You can also still use the HP Easy Scan tool, which is sold via the Mac App Store, to use the scan function of various all-in-one devices from Hewlett Packard.

What can be done – also affects Amazon Music There is currently no direct solution, the HP programs will probably have to be updated. Affected people can try to delete the HP programs – this is offered by the system anyway – and to delete the printer in the system settings and then reinstall it. You should ignore the HP utility. You should then be able to continue printing normally using the system function. The special functions of the HP Utility are partially lost.

Meanwhile, there seem to be similar problems with the official application of the Amazon Music service. Their users can no longer start the app either. The incident is reminiscent of a similar problem with security certificates of the popular apps from the developer Charlie Monroe – Downie 4 & Co. did not work for several days due to a signature withdrawal and were only usable again after updating. Apple’s “anti-fraud system” seemed to have made a mistake here.

According to information from HP to The Register, the printer manufacturer was responsible for withdrawing the security certificate. They worked with Apple to “restore the drivers”. Until then you should uninstall the HP drivers and use the native AirP
