“HPDeviceMonitoring.framework” will damage your computer.

Campbelle1, Could you post a link to the file you downloaded?

I had this problem. I have an HP printer and I used the HP site diagnostic help. It worked.

I installed the update directly from HP - the Apple update got corrupted (5.1) so we just replace with the HP version and works fine

5.1 update just showed up and fixes the problem.

I am having the same problem. When I looked in the Lanchagents and launchdaemons folders I could only find files with the offending name that were created in 2017. But I wonder whether this is beside the point. Has anyone else noticed that there is another thread https://discussions.apple.com/thread/251948836

asking if 'hpPostProcessing.bundle' is malware?. There are a whole lot of complaints about other messages popping up and problems with using HP printers which have been posted today. One suggestion points to the fact that 32-bit applications (including Drivers) are no longer supported in Catalina. Another suggests the security certificate was revoked by Apple.

Whatever the backstory, it seems likely that underneath this is a compatibility issue. So the big question is why has this happened and why haven't HP and Apple fixed it?

Hi, louisa63. Here's a link to an article that tells you how to access the Library. Apple hides that file by default but you can either see it temporarily or set things to always be able to see it (which I have done). Good luck! https://www.lifewire.com/os-x-is-hiding-your-library-folder-2260833

P.S. to the full uninstall/install using HP Quick Start that I just described.

Now the Software Update reports that HP Printer Software Update 5.1 is available for my Mac. I have NOT tried this since I don't want it to quit working, way behind from not being able to print today.

Go to page 4 of this thread and follow TC Meyers troubleshooting steps.

I spent 2 hours prior to this trying the other suggestions which didn't work.

I have not had any problems since uninstalling and reinstalling the software as per the steps provided by TC.

Hope this helps.

This exact thing happened to me I deleted my printer and then installed the latest HP printer software and then tried to add my printer and couldn't I've found this article https://www.theregister.com/2020/10/23/hp_printer_macos/ which says it's a mac and HP printer problem

Do you now get a notice that there is an upgrade ready for download? When I removed the specific file within that folder, there was a notice of an upgrade for HP Printing 5.1 and if you upgrade, the problem returns because it re-deposits that folder.

The exact same problem suddenly occurred for me 2 days ago... sudden loss of connectivity with my office printer (HPEnvy7640) and even worse, the frozen HPDeviceMonitoring.framework pop-up. So I read the solutions and prepared to use the method proposed by tcmeyers in this forum (so much gratitude for tcmeyers and Lindenbaum!) if Apple Support could not suggest a better alternative. After 15 minutes in chat with entry level Apple Support, a senior agent recommended the same solution as tcmeyers (but with a level detail clearly indicating purposeful evasiveness.) The first agent attempted to place blame directly on HP and said directly this is not an Apple problem. Although I don't have the evidence this is true, I'm skeptical due to the fact some OS aren't affected at all. Anyway, I have concluded that Apple Support wants nothing to do with providing a detailed solution for this problem and is referring everyone to HP. On a positive note, the senior advisor confirmed that their engineering department has found no risks with uninstalling device software and reinstalling. So I followed the method proposed by tcmeyers, uninstalled and reinstalled, restarted my computer and the test page was successful with my home printer (HPOfficeJetPro9020). My office printer (HPEnvy7540) has yet to be tested. That's for another day. :) Thanks to everyone for posting their comments and looking after each other... glad to be part of this global community.

For me the HP update that came through at the end of the day that day worked. I did not receive any more warnings that the device-monitoring framework is damaging. But now this morning I am getting similar dialog boxes about two other HP frameworks:

I am guessing that we will have to wait for HP to issue another update.

Someone in an HP Community thread posted that Apple did a temporary fix and posted this link with descriptions. Both my MacBook which I unsuccessfully tried to uninstall and reinstall drivers on and my iMac which I did not make any changes are now able to print.

Rolaa’s procedure worked for me with one addition: had to look for the actual file being executed and remove it, as well as update the launchhd daemon.

Side note: this came in via MS Teams, so I deleted that and reinstalled it.

Any new updates on how to solve this problem? I can't print except through my e-print email. This is very annoying! Didn't have the problem until I installed Catalina 10.15.7. on my MacBook Pro!!

Solutions to this problem, caused by HP not Apple, are posted all over these forums. Do some reading to find out how to fix this. You need to download and install new HP printer drivers. Catalina 10.1.5.7 has nothing to do with this. HP canceled, in error, their security certificates around the same time as the Catalina release. Sheer coincidence.
