Fix Encryption Credentials Have Expired when Printing on Mac
1 Method. Uninstall printer drivers and use native AirPrint driver
If Encryption Credentials Expired error prevents you from printing on Mac, you should delete the printer from the printer’s list and also try to create a new certificate for it. This method reportedly works no matter the manufacturer of the printer – be it Canon, Toshiba, HP, Dell, or others. Many Mac users have noticed that they are unable to print via their HP printers recently; the one to blame is actually Apple, who revoked HP printer driver’s software’s certificate via XProtect. The issue also might occur for certain printers after updating the operating system version. XProtect (alternatively known as File Quarantine) is known as a mechanism that Apple uses to inform computers about no longer trustworthy programs. From certain point of view, it can be called Mac’s anti-malware system. The “trustworthiness” is determined by adding or revoking application code-signing certificates. It appears that the computer giant has revoked HP’s certificate recently, causing problems for thousands of users worldwide. To be precise, the majority of affected users seem to be running Cataline or Mojave OS X. In order to fix the issue, we suggest following the given steps: That’s it! You should now be able to print using your HP printer on Mac again, and you shouldn’t run into Encryption Credentials Have Expired message or * will damage your computer message again.
