Connecting MacBook Air (2020) to HP OfficeJet 4650
I can't seem to connect my new MacBook Air to my HP OfficeJet 4650 printer. The printer used to show up in the list (through System Preferences), but I followed another community suggestion to delete the printer then add it back in, and now that I've deleted it (using the minus button), I can't find it again.
When I tried to open the downloaded printer software from HP, I got an alert that Mac can't open without Rosetta Stone, so I downloaded that. Now when I tried to open the HP installer, I get an alert that Mac can't open it because Apple can't check it for malicious software and I'm supposed to contact the developer.
The MacBook Air is brand-new, my printer is just one year old, and I'm pretty flummoxed right now!
Any help is greatly appreciated!
