“HPDeviceMonitoring.framework” will damage your computer.

Yes. Followed your instructions exactly. My 6940 software does not come up as an option. Loaded the August 2020 driver from HP for the 6940 and it still gives the same issue. In fact, while loading the software it says that the certificate is expired and may not work well. >sigh<

Thanks tcmeyers. I now see com.hp.devicemonitor.plist in ~/Library/LaunchAgents added yesterday, Oct. 22 at 11:08 a.m. Based on the action taken by REW1027 (5:07 PM), I am thinking that REW1027's approach might work.

--> Ugh. Perhaps direct connect by USB temporarily?

I tried, it doesn't work

--> maybe use Printers & Scanners in System Preferences and the ➕ to add the printer through the Time Capsule

I tried, it doesn't work

Aqua_RT, that might work, though for me it didn’t. I used the ➖ in the Printers & Scanners panel of System Preferences, but no app I have magically restored the instance. Then manually using ➕ to put it back I still wasn’t able to print. Only doing the complete Uninstaller method from HP got me cleaned up enough to put things back.

No, that doesn't work either. I directly connected the MacBook Pro to the printer via USB cable and this time the HP Easy Start "saw" the printer. I set up the printer but I still cannot print: It tells me that the printer is offline (although it is directly connected to the MacBook Pro), or "looking for the printer" but never find it. I"ll give up!

I deleted each folder that popped up having a conflict. I had this problem too. It ask you to select OK, or Finder. Click finder it will open some folders. I deleted the HPdevicemontoring.framework folder, HPDM.framework folder and matterhorn.framework folder. Basically I deleted each folder that flashed up on my screen. This seem to do the job. Was able to print no problem. I have an HP 8600.

Aqua_RT,

That’s what was preventing me from printing too, the “Stopped - Can’t open” error, too. But that was solved by what I described.

Just double-checking, you did do the Uninstall step before anything in the HPEasy Start app?

Hi tcmeyers. Yes, everything was done precisely as you describe in your 2:25 PM message. When I reached the step

"Select your printer (mine is a printer on the network, it just shows up by its name, e.g. "Anubis") and click Continue."

I received the "No devices have been found" after the HP Easy Start app spent a minute or so looking. I have seen that before in my MacBook Pro with HP LaserJet Pro MFP M125nw system. Normally I just add the printer with the Internet Printing Protocol, and everything works fine. It seems something is seriously wrong in the HP printer - macOS ecosystem, at least for my system.

Hey guys

Don't erase the framework!!! It isn't a malware but part of the HP operation system. It's the last apple update (looks like the safari update to me) that has caused this irritating message to popup!!!

People that erased the framework, following the 'advice' experiencing loosing their connection with the printer.

It's Apple's fault and they have to solve it.

So I had the same annoying pop-up. Couldn't get rid of it. Called Apple Care support (800-692-7753). Other's had reported same issue. Tech did screen share with me. We dragged to trash several HP files. That got rid of the pop-ups but now I am unable to print. We were unable to reinstall my HP printer (office jet 5470 series) software. Supposedly Mac should recognize the last printer used, but it didn't. We tried via the 123.hp.com website multiple attempts. Printer and laptop on same network. My laptop could not find my printer. (Never had this issue before, and I can still print from my iphone). Tried all the usual tricks, shutting down, unplugging, and restarting everything. Tech finally gave up and told me I needed to purchase a USB cable to connect to my printer. Three hours later, I am still trying to install software. When I googled the issue, Apple advises not to install printer software from HP, but to use their software, but this also failed. Via system preferences>Printers & Scanners, I manually added the printer's IP address. HP 5740 series came up, but when I clicked on 'Add', I get the message "inkjet1.driver will damage your computer". I am so sick of this. It's 1 AM. I'm going to bed. Maybe a miracle will occur overnight.

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

I think it's the way in which you uninstall and reinstall the software that makes the difference Alison.

I followed the instructions provided carefully, step by step and it works.

I believe (I might be wrong) but if you follow the default installation settings provided by HP then this may be the cause of your problem.

I followed your steps. But HP will not provide any driver for my Printer (HP LaserJet CP2025). I can reinstall the Printer in the Systempreferences, Apple will provide a new driver an it installs as it should.

But I still can’t print, there’s not output on the printer (wether when connected to the network nor when connected to USB).

The post by @TCMeyers on page 4, going to 123.hp.com, using HP Easy Start to uninstall and reinstall, worked for me! The next morning I did see the update from Apple for HP Printer Software Update 5.1 as well, but mine was working prior to that.
