PLEASE check in with us before upgrading to macOS 10.15 Catalina
From October 2019
MacOS Catalina 10.15 will make many older applications unusable after you upgrade. Potentially incompatible apps and devices include EHR systems (like MacPractice), digital radiography sensors, and other specialized equipment. Popular software like Microsoft Office 2011 and some Adobe CS6 (and older) applications will no longer work at all with the new operating system.
Beyond fully disabling some apps, keep in mind that the very first version of software like 10.15.0 (before any ‘patches’ or updates) can often be buggy, unstable, and incompatible with the software you use every day. Unless there is a compelling reason to upgrade, in general we advise against upgrading at this moment.
Here’s how to find out which apps you currently have that will be no longer work after upgrading to macOS Catalina 10.15.
Once you have verified that you can safely upgrade to 10.15, here are some new features that might benefit you:
• Better Data Protection: The operating system runs in a dedicated read-only system volume that prevents anything from overwriting or subverting critical files. Apps also have to be “notarized” by Apple, which means they have been checked for known security issues.
• Mail App: Mail is changing its classic layout to a column layout with a preview of selected, but unopened emails. Mail can now block certain email addresses. It also can mute long email threads and lets you unsubscribe from mail newsletters more easily.
• Notes App: Notes will now have better search options, a gallery view, and folder sharing capacity with a “read-only” sharing option.
