Your Mac does not have malware, it's just got printer drivers that HP mistakenly asked Apple to block. Here's how to work around the problem.
Hewlett Packard has now explained the recent spate of Mac printer problems that saw users being warned of 'malware' — but it hasn't yet solved it. While HP and Apple are reportedly working together to resolve the issue, users are still being prompted with warnings saying it 'will damage your computer.'
'We unintentionally revoked credentials on some older versions of Mac drivers,' said a HP spokesperson. '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 best antivirus for MacBook Pro is one which is able to detect viruses and malwares in the system and easily get rid of them. Such an antivirus, therefore, should have real-time updates of virus definitions regularly updated to help fight off new attacks.
Yet another group of cyber predators haunting MacBook Pro laptops is the infamous blackmail virus. Better known as ransomware, these infections are targeting Macs increasingly but haven't yet reached a massive propagation milestone, as opposed to the way things are on the Windows arena. We think Bitdefender Antivirus for Mac is the best Mac antivirus program. It had a nearly invisible impact on system performance, caught all Mac and Windows malware in lab tests, rolls back files.
As previously reported, AirPrint is the answer if you need to actually print anything out. Apple yosemite mac. To get rid of the repeating error message, though, you may still need to take certain steps.
- Go to System Preferences
- Click on Printers & Scanners
- Choose your HP printer from the Printers list on the left
- Click the minus sign at bottom left
- In the Finder, go to ~/Library/Printers/hp
- Drag the printer driver to the trash
- Go back to System Preferences
- Click on Printers & Scanners if it doesn't open at that
- Click the plus sign at bottom left and re-add the printer
To go the ~/Library/Printers/hp folder, go to the Finder and choose Go, Go to folder.. from the menus. Or press Command-Shift-G.
This will clearly delete the printer driver, but what it then does is force your Mac to download a new copy. Once you've re-added the printer, it will be using the new, updated driver and should work correctly.
These steps should fix the issue because HP has effectively undone its mistake. According to The Eclectic Light Company, the problem was that what HP asked Apple to do was revoke its security certificate for the file 'HPDeviceMonitoring.framework.' In theory, then, this can just be un-revoked.
However, The Eclectic Light Company says that at time of writing, users are still reporting what appear to be related problems. If you're in that situation, there currently seems no better alternative than contacting HP support.
