MacOS Catalina: 9 Things You Need To Know Before Updating

MacOS Catalina: 9 Things You Need To Know Before Updating

The new Mac operating system makes some deep changes, which means that at least a handful of apps on your Mac will break.

I noticed the problems with Catalyst last night when I booted up the initial shipping version of macOS Catalina last night and headed into the Mac App Store to see what was new. You'll see all your apps split into two groups - 32-bit and 64-bit.

Any creative professional will tell you that it's not a good idea to update to the latest version of any operating system the day it comes out. The feature allows users to use their iPad as a secondary or extended display of their computer.

Another reason to skip macOS Catalina (for now) is that it no longer supports 32-bit apps (only 64-bit apps will run on Catalina). American Airlines, TripIt, and Post-It apps are now available with the Catalina update, and Apple is expecting to add more apps-including Twitter-to the desktop in the coming year.

The new Find My app combines Find My iPhone and Find My Friends into a single, easy-to-use app on Mac, iPad and iPhone. There's also stricter privacy controls that require apps to ask permission to access your desktop to keep you protected from any nefarious app developers. At this point, you're probably familiar with macOS 32-bit compatibility warnings. Folks walking around with internet-enabled smartphones in their pocket don't really need to stash a dedicated mp3 player too, making iTunes on Mac increasingly redundant for the mass market.


With the world becoming more conscious of security in times of data breaches, macOS Catalina enhances protections for Mac.

Which Macs and iPads support Sidecar? That's something that isn't automatically available to Catalyst apps, so few apps have adopted it so far. That changes in macOS Catalina, which adds natural language recognition, and the additional levels of complexity that your increasingly complex life needs.

So, how do you know which apps are going to break in Catalina?

Backups and iPhone syncs will be handled by Finder from here on out, FYI. Find My also finally makes it to Mac. You also get new filters, to see reminders due today, those scheduled for the future and those flagged as a high priority. This new app, Find My, is located in your Applications folder.

I've never really loved Apple's own podcasts app, but this latest version blew my mind with its new search tricks.
