No this has not turned into a real estate blog, we are talking mac OS 10.15 otherwise known as Catalina. The mac 10.15 Catalina OS is the newest OS for the Mac and marks the first Apple OS that requires 64-bit apps. The newest operating system for the Apple Mac was released earlier this month, October 2019. Most of the drivers for the new OS have been released and can be found on the support pages for the printers. Please check for the drivers before you upgrade your OS to avoid any printing issues from upgrading with no drivers available.
