Hi tbp1804,
Thank you for using the forum. There has not been a new Mac driver for the Phaser 6180 MFP since the release of 10.11 El Capitan. You can try to add the printer on he 10.13 macOS using the built-in Generic Postscript PPD in the Mac operating system.
Alternatively, you can visit the Phaser 6180 MFP Contact Us page for other support options.
Can anyone please help me?
From Tine
