'hpPostProcessing.bundle' malware?

Today I was working on my MacBook Pro and I wanted to print a document on an HP printer. When I pressed the 'print' button, Gatekeeper told me the following proces/application is malware and does harm to my Mac: 'hpPostProcessing.bundle'.

Normally I never have this issue when I want to print anything on the printer that I used today. Could anyone tell me if I need to assume that this process/application is really malware, or that I can assume that it is a 'false positive'?

Thanks in advance.

You did Not have to go buy a different printer. Almost none of the others who have posted on the now 6 pages of posts here had to do that.

---------

If you don't see it in Software Update, Apple now has it posted as a separate, manual download.

HP Driver update 5.1

https://support.apple.com/kb/dl1888?locale=en_US

--------

what you will need to do:

delete your old Printer Queue,

restart your Mac,

download new Drivers,

Add-A printer to get your full original functions back.

You should not have to fall back to generic postscript driver or AirPrint driver, but those remain as work-arounds.

where do you find those folders to remove?

Oct 26, 2020 2:06 PM in response to apebox

Excellent - worked great. Just make sure you trash the hp folder in the hard drive library, not the user library.

Widely ineffective isn't the same as trying it yourself. The biggest issue, it seems, is people didn't know about step C.

I have the same problem - deleting and reinstalling the printer did not work. Cannot even find drivers for my printer on the HP Page - anybody still having the problem???

QED, nerak100! My 1518ni is up and running again with all original printer features (and even back to printing in color). So happy, thank you!

Happy to help.

I resolved it on my own and with help from this site. Two calls to Apple produced wasted time with two different technical support reps. Thanks for the insight!

I think you will need to actually delete the old unsigned driver as described above.

After removing Print Queues, did you follow the advice in the HP article to download and run HP UN-Installer?
