Mac drivers for Photosmart 7760 won't load on Monterrey 12. 0.1

[Hepcat_Mac]

I have an HP Photosmart 7760 on a 2018 Mac Mini I7 running Monterrey 12.0.1   The current drivers on the HP website only accomodate up to Mac OS 10.4, and once downloaded, the driver install package won't run on Monterrey.  Help!  I need my printer!

I upgraded to Monterrey 12.1 this morning.   In researching further, I found this thread:

  https://h30434.www3.hp.com/t5/Printer-Setup-Software-Drivers/My-MacBook-Pro-and-my-HP-photosmart-776...

Per the instructions there, I downloaded and tried to install this package of drivers.  It reports that it requires Mac OS 12.0 or earlier to install, so that didn't work either.

So...  apparently until the driver installer is updated, I'm out of luck for printing???   😞

ok, one more post...  doing web research I found this thread on Macrumors.com in a post by a user named "theapplecynic."  Running this script in terminal, copying, pasting and running  line by line in fact solves the problem with the installer package.  The driver for my Photosmart 7760 is now installed.   I suspect that this will resolve install issues for most HP printers on Monterrey.  That said, it'd be nice if HP could update their driver installer to be current.

It works! Thank you for this post
