Updated Many Mac users today found, to their surprise, they are unable to print to their HP Inc printers.
To get the HP utility, you need to install the HP full feature printer drivers. Click on to download and install the printer drivers. Restart the MAC once done and go to Applications - HP - to get the HP utility and other printer programs.
- To add a new printer, just click on the Apple logo, select 'System Preferences,' click on 'Printers & Scanners,' and then click the '+' sign beneath the printers list. Follow this to add as many printers to your Mac as you want. That's all there is to do. Your printers list is now empty and there are no printing jobs in the queue.
- How to Uninstall and Reinstall your Mac Printer Driver. Follow these steps to install the beta Mac driver for your printer: From the Apple menu, select System Preferences. Click Print & Fax. Highlight any Epson printers and click the button to remove them from the Printers list, then click OK. Open the Hard Drive. Select Library Printers.
This is due to a code-signing snafu affecting macOS Catalina (version 10.15) and Mojave (10.14), specifically. HP's printer driver software is cryptographically signed with a certificate that macOS uses to determine whether the application is legit and can be trusted. However, that certificate was today revoked through an XProtect update, causing the software to be rejected by Macs.
XProtect is the mechanism Apple uses to inform Macs to no longer trust and run certain programs, and it does this by revoking their code-signing certificates. There is no central database of certs cancelled by XProtect, there's one for each OS version it seems, and Catalina and Mojave were selected in particular. Apple chose to revoke the HP driver cert, or perhaps was asked to do so by HP.
'No questions asked' Windows code cert slingers 'fuel trade' in digitally signed malware
READ MOREIn any case, HP's driver software no longer works on those two particular operating system flavors. Users are told when trying to print, for instance, that HP's application 'will damage your computer,' and are given the option to run it anyway or send it to the trash. Trying to continue just loops you back round to the error message, with no work done. Punters are also encouraged to report this 'malware' to Apple.
Unofficial workarounds for now include using AirPrint to an HP printer, or uninstalling the HP software and using a generic PostScript driver.
A Reg reader who tipped us off about the blunder told us he was able to jerry rig some IPP connectivity to get an older device to print: 'We had a handful of printers where macOS would print into the ether. Windows had no problem. I found some IPP trickery on macOS Catalina worked on an older HP4650.'

Complaints from punters are building up on the Apple and HP support forums.
'Trying to open Printer Utility on MacOS 10.15.7 and I get a crash dump every time saying 'Code Signature Invalid' for the binary /Library/Printers/hp/Utilities/HP Utility.app/Contents/MacOS/HP Utility,' said one netizen.
'Yes, my Deskjet F4140 abruptly stopped working with both my Mac mini desktop AND my partner's AirBook,' complained another. 'The AirBook keeps insisting it's malware (it's not), while my desktop says the certificate has expired. Suddenly, HP and Apple are NOT playing well together! I've redownloaded and reinstalled the printer software TWICE now but nothing has changed, just the same message about HP Utility now missing. Our jobs depend on this printer, HP.'
Thomas Reed, director of Mac and mobile at Malwarebytes, tweeted to say his users were up in arms at the tech breakdown: 'We're seeing a significant influx of support cases where users are seeing macOS identify what appear to be legit processes as malware.'
Mac blogger Howard Oakley has some more background, here. 'You're seeing that [error] message because macOS is checking the signature on your HP printer software, and being told that its signing certificate has been revoked,' he observed.
Amazon's Music desktop app is also, weirdly enough, no longer working, either, it's reported.
Spokespeople for HP and Amazon were not available for immediate comment. Apple declined to comment. ®
Updated to add
The Register understands from sources familiar with the matter that 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.
The macOS Big Sur update is probably one of the most feature-rich updates that Apple has released recently for its macOS machines.
It carries several improvements and even brings one of the biggest UI overhauls to macOS, bringing it more in line with the UI offered on iOS 14. Parallels desktop 7 switch to mac edition.
Of course, a quick Google search will serve you dozens upon dozens of articles detailing all that's new and the same goes with videos on YouTube.
But before getting excited about the new features and improvements, it's also worth noting that, like most other software updates, the macOS Big Sur update also has its fair share of bugs and issues.
Take for example the bug we reported of earlier which prevents some MacBook users on Big Sur from booting their devices while connected to a monitor via Thunderbolt.
Now, another issue appears to be troubling many Mac users. After installing the macOS Big Sur (11) update, users are reporting that the printing function is now broken.
We've shared multiple reports from affected users below:
Printing went well on Catalina. Now printing stopped and showed message ‘Filter failed'. Using printer Lexmark C543 and removed and entered the printer once. Same problem. Printer supply is visible in browser. Seems to be OS problem. (Source)
Same problem overher with my Lexmark CX310 when i print. Printer receives nothing it even does not even wake up. Tried to install new drivers from Lexmark but this is also resulting in an error so new driver are not installed. (Source)
My company we run a Canon C5035, we updated all the iMac 2019 and MacBook to OS Big Sur…Now when we print the text comes out as gray squares. This is a monumental problem for our business. Please provide support ASAP. (Source)
I already updated the latest version MacOS Big Sur Beta 11.0 (20A5384c) but after updated i got some issue in printing the documents. In first beta update document printed but only pictures are printed no paragraph is printed. After second update my new printer HP Laser jet Pro M15a installed but not printing even no error showing. Need support on it. (Source)
Reinstall Hp Printer Driver Mac Download
As you can see, the problem seems to be affecting users with all sorts of different printers. Winzip full mac. Therefore, it certainly cannot be pinned down to a certain printer model or even brand for that matter.
At present, the problem has not been acknowledged by Apple directly, although it does have a general fix for printing issues that we've shared below.
Furthermore, what seems to be the most likely issue is the printer drivers or rather, lack thereof, as highlighted by a user and a report.
I was able to print using a USB cable though, after downloading the latest driver and connecting to the printer via an old USB type 1 cable that I had around. Seems like Epson needs to update their driver software. (Source)
Most printer manufacturers are yet to release new drivers with support for macOS Big Sur. Therefore, it's more than likely that most issues would be fixed once the updated drivers go live.
But until then, you might want to try these possible workarounds which may fix the problem for you.
Workarounds for printing issues on macOS Big Sur
1) Reset the Mac printing system (official fix):
1. On your Mac, choose Apple menu > System Preferences, then click Printers & Scanners.
2. Press and hold the Control key as you click in the list at the left, then choose 'Reset printing system' from the menu that appears.
3. Skyrim like games for mac. After you reset the printing system, the list of printers in Printers & Scanners preferences is empty.
4. Re-add any printers.
This should fix the issue for some users, however, there are chances that your printer might not work even after performing the steps above.
2) Download the open-source Gutenprint driver:
How To Reinstall Printer Drivers
It seems that users have managed to fix the problem after downloading and installing the Gutenprint driver which is completely free. All you need to do is download the latest package from here and install it on your Mac computer.
3) Check for the latest drivers:
Make sure that you have the latest drivers for your printer installed on your Mac computer running macOS Big Sur. There's a possibility that the current printer drivers aren't supported on the latest OS.
Therefore, updating the drivers to the latest version might fix the issue for good. Most manufactures provide the drivers on their websites so you should be able to get your hands on the drivers within a few minutes.
That being said, we will continue to keep an eye out for any new developments regarding the broken printing function on macOS Big Sur and will post an update once new details emerge.
