HP Scanner 3 will harm your computer

Mac OS Catalina (10.15) with HP OfficeJet 8620 installed wirelessly. Has been working fine until today when I received subject message. I am unable to find "Easy Scan" on my computer so cannot delete it as indicated by previous support recommendations. Also, I am unable to connect to the printer and am a bit queasy about reinstalling it with the malware.

It's not malware.


From sources familiar with the matter, HP Inc asked Apple to revoke its printer driver code-signing certificates. It appears this request backfired as it left users unable to print. A HP Inc spokesperson told us on Friday night:


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.


HP supplied a new driver on Friday to fix the issue:


ftp://ftp.hp.com/pub/softlib/software12/HP_Quick_Start/osx/Installations/Essentials/hp-printer-essentials-S-5_14_8_4.pkg


However, that "fix" is producing this error for some users:


"Matterhorn.framework" will damage your computer…


If you're seeing that, try this fix. Go to System Preferences, select Printers and Scanners. Select your printer from the list then delete (-) it. Then add (+) your printer back and select the generic driver to use.


Update: HP Printer Software 5.1 should now be becoming available through Software Update to fix this issue. (2220 UTC 23 October 2020)



Open  > System Preferences > Software Update      (Command R will reload and do a fresh check)

Thanks to everyone for their comments/suggestions on the "HP scammer 3 will damage your computer" problem question.


I have now used Apple and then gone to HP SMART FOR DESKTOP. Then followed - open - select scan - then, at the bottom right there is another scan, then save and follow on from there. Success!!! !!! Used it twice and both worked - rather scared of a third attempt but that can wait for the present. Why on earth Easy Scan no longer works, perhaps HP could tell us????

Apple released an HP patch this week. Make sure your Mac is up-to-date. If that doesn't work and you are somewhat computer proficient you can try this which solved my problem before the patch was released: (see Kurt's answer)


It’s an HP issue, and is incredibly easy to fix.


1. Delete the HP folder here: /Library/Printers/hp

2. Open System Preferences → Printers & Scanners

3. Delete your HP device. (It may appear more than once; delete all instances.)

3. Download and reinstall the HP drivers and program from here: https://support.hp.com/us-en/drivers/printers

I have an annual plan with Geek Squad through Best Buy. I spent an hour and ten minutes virtually with them. They fixed the problem by uninstalling the printer and re-installing printer and all the drivers and cleaning up my computer. Everything seems to be working now. Worth the money I spent on my Geek Squad Plan!!! Apple Help tried also for an hour but exhausted everything with NO LUCK! HP really screwed this one up!

I would appreciate help, I have read the entire thread, tried multiple proposed solutions. I am still unable to scan. I have a wonderful HP Color Laser Jet Pro MFP M277dw. I searched the HP website and could not find the drivers for it. It is not that old. They screwed the pooch on this one.


It stopped working within the last month. I have upgraded to macOS Big Sur 10.0.1 - can someone teach me how to fish here? I would love to know what I am missing.


The Mac HP 5.1 update has been installed and am unable to see it after I removed my printer. (Yes - Command R doesn't show it)


Thank you for any help you an provide.

Several weeks ago, I was able to get my HP printer to work again by uninstalling and reinstalling.


But, here is another solution for those who have been frustrated with this for a while and really need to get to printing and scanning.


A few days ago, I got a message that there was a problem with the printhead (unrelated to the problem we all have had with Big Sur and HP.) Essentially, my printer was dead after about 5 years.


I bought a new HP Desk Jet Plus 4158 printer/document feeder scanner at Sam's Club for $84. All I need for my home printing. There were others for $150 or so with more features than I needed.


If you really need your printer and have been trying for weeks to get it to work, ask yourself if it is worth $100 or so to put this behind you and have a brand new device.

The last drivers has available for that scanner is for macOS 10.14.x, Mojave.


https://support.hp.com/us-en/drivers/selfservice/hp-scanjet-g4050-photo-scanner/3236371/model/3236374


No idea if these are 32 bit drivers or 64. The latter would be required for Catalina.


This same driver download page does point you to another page for a "fix".


https://support.hp.com/us-en/document/c06960563

So, you may want to download and run their fix first. Then download and install the 10.14.x drivers.

I've got Catalina 10.15.7. I think I'm S.O.L. The first HP link says, "We were unable to find drivers for your product." The second is for the HP Printer Driver that I've tried before and doesn't work for my stand-alone scanner. It looks like I need to buy a new scanner. But at least I can now stop trying all these fixes. Thanks for helping me clarify.

This post instructions worked like a champ! I followed the instructions to a tee on my iMAC. I had already downloaded HP drivers, which may have had something to do with not having to perform the last step/bullet to install the latest HPl driver software directly from Apple. I immediately was able to scan a document with no messages or being lockout from using the printer alltogether. I have an HP Photosmart 6520 printer, scanner, copier.
