Mac OS 27

[AJsAWiz]

I installed IOS 27 on my iPhone. My Mac is currently running Mac OS 26.6.2 and getting ready to install Mac OS27.

I received the following message: 

"System Extension Blocked A program tried to load new system extension(s) signed by “HP Inc.”. You can enable these extensions in Privacy & Security System Settings."

My question is this. Will I encounter issues with my hp printer after installing Mac OS 27?

Hi @AJsAWiz 

1. There should be no problems to work with a new MacOS system update.

2. But, because MacOS 27 is just new, probably it could take a little time to update drivers for Laserjet printers for that MacOS version.

• Right now, there are only drivers for Mac OS 26. (updated on August, 14, 2026).
• How much time 🤔, well, I don't know, maybe a month or two to find updates.

3. You can check for updates in the next HP Support page:

• https://support.hp.com/us-en/drivers/swdetails/hp-laserjet-pro-m400-series/model/7458634/swItemId/mp...
• 

4. Also there is a list on Apple Support to check for enabled printers that work on MacOS:

• >> Apple Support search list for AirPrint enabled printer
• • 

5. Like a general advice, if your printer is working fine, maybe you should wait with your actual MacOS version until an updated Printer driver shows on HP Support pages. 😇
