HP printer drivers no longer working on OS 10.15.7

Question

HP printer drivers no longer working on OS 10.15.7

Suddenly, I receive a message that my HP printer/scanner/inkjet and laser jet printers' drivers are malware, and no longer work on any of my iMac computers or other Apple devices. I read that a glitch in the Apple security system recognized HP as malware. In response, HP has asked Apple to pull their certificates. Our only workaround is using generic drivers and losing multi-functions on these office machines. A total non-starter. Is Apple working to fix the issue? Is HP trying to fix their Apple certificate issue? What is the bottom line of this story? Does our HP office equipment now become door-stops?

No, I sure hope not. You can go to System Preferences, then security and change download + open all apps only from recognized developers to open everyththing. For that you'll need your login name and password. of course it might be a bug in 10.15.7

good luck to you

No bug in 10.15.7. This is actually old news. Almost two weeks ago now HP mistakenly revoked the security certificates for their printer drivers and killed a whole lot of HP printers on Macs. HP admitted its error and released new drivers which can be downloaded directly from HP or through Apple’s Software Update panel in System Preferences. Basically you remove your HP printer from the Printers & Scanners panel, install the new drivers and then add your HP printer back to the system.

my HP printer/scanner/inkjet and laser jet printers' drivers are malware,

This is certainly the sign of the HP certificate problem.

This solution doesn't work.

What steps did you take?

What error message?

The printer driver for my older printer only works with OS 10.14, and we

have 10.15.

You can always downgrade to OS 10.14.

So, my HP printer, which worked just fine until now, does

become a doorstop

What OS was it on when it last worked? Did it work with macOS 10.15?

You can always hope these folks will get their act together.

Get the free Oracle virtual box. install linux in a vm. Share some folder. Print from linux to your printer. Perhaps you can share the linux printer and print to the shared linux printer.

I did everything. This is the error message that I get over and over and over:

"HPDM.framework will damage your computer. This file was downloaded on an unknown date. Report malware to Apple to protect other users"

I confirmed that Apple has canceled/dropped the HP certificate. Therefore, nothing from HP will currently load on Apple without Apple Security recognizing it as malware. This is regardless of how you set your security settings. I installed the generic drivers from Apple and I can print and scan, but only basic vanilla stuff with no whistles and bells. Apple and HP will have get together and resolve the certification issue to fix the problem.

I don’t understand why, after almost two weeks now, people don’t get it. Don’t people read these forums before coming in and posting like this is something they just now discovered. HP has long since admitted they dropped the ball and hosed thousands of their printers being used on Macs. HP has released new drivers that restore their printers to proper functioning. Catalina 10.15.7 has absolutely nothing to do with the issue. It was just coincidence that 10.15.7 came out around the same time that HP screwed up.

So instead of posting about how someone messed around with the system to no avail just follow the advice of dozens of skilled volunteers that man these forums.

Before I posted, I downloaded and updated all HP software and drivers. IT DOES NOT WORK. Again today, checked for new HP drivers and associated software. It still does not work. It has been doing this for at least two weeks. According to Apple, HP voluntarily pulled their certificates because of issues. Until HP issues new certificates that Apple will accept, the HP drivers and software do not work. Today, HP issued driver and software updates for the Windows 10 platform, including new certificates. Perhaps they will also issue the updates for the Apple systems, but as of yet they have not. Until HP issues their new certificates with their updates, we are forced to use Generic drivers. And you are right, Apple support can do nothing other than recommend the Generic work around. The fix is in the hands of HP. But it is not a coincidence that OS 10.15.7 came out at the same time. It has everything to do with Apple security rejecting HP with no current certificate.

Have you download the new drivers? --yes--

Delete the printer in apple icon > system preferences > printers and scanners?

Add the printer back.

Should work. If not, we will need to go over what you have done in details.
