Updated to Tahoe (macOS 26) and now printers do not print

Thank you leroydouglas

This part :

I would verify some settings—

>System Setting> Privacy & Security> Local Network toggle on all related

worked for me. The problem was with an Epson ET-16650

I recently updated to macOS 26 Tahoe. Now, none of my printers work. Not the usb HP printer nor any network printers.

I reset the print system in Print Center and reinstalled the usb printer. No good. I deleted everything in /Library/Printers folder and reinstalled the printer. Still no good.

The error log reports a plethora of errors, but the all seem to be centered around File “/usr/libexec/cups/daemon/cups-deviced” has insecure permissions.

Please advise.

Reset print system if necessary:

If it is listed as AirPrint printer, delete the existing printer, and add it again, select AirPrint.

Thanks for the advice. Unfortunately it did not work.

Did you look at the error logs for any insight

From the Finder>Go>Go To Folder, copy & paste:

/var/log/cups

no insight or resolve it may benefit to list what exact printers are involved here.

Same issue here since upgrading to MacOS 26.1 from 26. Printer is a HP Laserjet Pro M428 MFD). Spouses Mac is still on MacOS26 and it prints fine. My Windows 11 system also prints fine. iPhone prints to same printer just fine.

Something in the MacOS26.1 update has broken something.

To "The Fingers" - What solution are you referring to? I don't see a clearly identified solution in this thread.

I deleted the printer on my MPB 16" M1 Pro but could not find it again to add back. I installed the HP Software and it cannot find the printer plus it's a piece of crap.

The printer has an IP address that can be pinged or the embedded web interface brought up on a Windows 11 system just fine. On the MacOS 26.1 Mac, I cannot ping the printer in terminal or bring up the embedded web interface. Both again work on our MacOS 26 version which has downloaded the new update but we are not restarting it. I wish I knew how to delete the scheduled install. I read a few posts saying look for an update file in the applications folder or in the Library folder but nothing existed. I did a CLI "software update blah blah) and the latest I see listed is MacOS 26. The article I was reading indicated that the software update CLI command would list the downloaded update.

This leads to another question, when the Software Update section of System Preferences shows Scheduled, Restart now or Install tonight. Does that mean the downloaded update has already been installed and only a restart is needed or will is download when I initiate the restart?

Tons of old and unvalidated information out there.

This is the first time and many years that I will turn off future updates and delay install until much later.

I have a Xerox printer on my network. I have configured the printer using cups on a Mac mini running tahoe.

I can print to the cups queue from the mac mini itself, but after removing and re-adding the shared cups queue on my mac studio, also running tahoe, I can't print anything, getting an 'Invalid Certificate - check the printer for errors" in the print center queue on the studio.

Here's what's in /var/log/cups/access_log when I print to the queue:

localhost - - [02/Oct/2025:19:45:42 -0600] "POST /printers/BW HTTP/1.1" 200 1499 Create-Job successful-ok
localhost - - [02/Oct/2025:19:45:42 -0600] "POST /printers/BW HTTP/1.1" 200 8346 Send-Document successful-ok
localhost - - [02/Oct/2025:19:45:42 -0600] "POST / HTTP/1.1" 200 347 Set-Job-Attributes successful-ok

localhost - david [02/Oct/2025:19:45:43 -0600] "POST / HTTP/1.1" 200 8265 CUPS-Get-Document successful-ok

There's no error, and nothing appears in the log on the mac mini.

On the mac studio there's several lines that look like this in the logs:

error	19:58:33.605496-0600	dnssd	Disabling saving preferences for { dnssd, <private>, current host, (null) } because home directory is inaccessible
error	19:58:33.637531-0600	ipp	Disabling saving preferences for { com.apple.ipp, <private>, any host, (null) } because home directory is inaccessible

Anybody have anything for me?

I am unable to get Microsoft Word to display a print dialog in Tahoe 26. I can print from Acrobat and Pages, but when I try to print from Word, the print dialog doesn't even pop up anymore. Everything worked fine for years until I upgraded to Tahoe 26, and yes, Word is updated. Exporting Word documents to PDF for printing changes formatting for some documents.

Additional info:

The issue only started when I upgraded FROM MacOS 26 to MacOS26.1 on a Mack Pro, M1 Pro 16.

We have another Mac running MacOS26.0 and it prints fine.

Printer is a HP Laserjet Pro M428 FWD.

This is outrageous that a security update prevents printing. My only other Mac has the update wiring to apply. I am not restarting in the hope that a fix will evolve. If not, I'll be back on Windows after a good run from 2010 on Mac.

I think this needs its own thread as my printing issue is only related to the 26.1 MacOS update.

Can Mr. Woo clarify if he's on 26.0 or 26.1? This matters.

I see my original post was edited by a moderator. I only wish Apple's engineering team were so quick to comment in these communities to acknowledge a problem and provide an ETA for a fix. I know, I have never seen this kinda proactive customer facing communications from Apple.

Hi! What does a clean install mean? I have the same problem with printers. Everything is offline and nothing helps

I have the same error when the shared printer is added from the "Printers & Scanners" as when it is configured in cups.

This is indeed the solution. Thank you so much for posting it!
