It’s been already another year and a new version of macOS is here to replace macOS Mojave. The new major update called macOS Catalina was revealed at WWDC 2019 by Apple this June with all the new major features and changes which makes the experience every year better and moves the technology further.

In this article, you will find everything new in macOS Catalina, what you need to do to prepare for the update and why some things like some of your apps might not work in this version.

 

When will the new macOS Catalina be released?

Initially, Apple announced at WWDC that they will release the new version in the fall of 2019. This is very usual, and we expected it to come on September 19th at the same time with iOS 13, however, Apple Changed the release date to October, which is still in the fall, but very unusual. We don’t know the exact date in October, and I believe Apple wanted to make sure they have time to fix some problems in the system before the wide release. In my opinion, we will probably see this new version in the week starting the 21st or 28th of October.

 

How to update to macOS Catalina?

You will have to update through the Mac’s App Store. You will most probably see a prompt or a notification badge on the App Store when the update is ready. Be prepared to download a couple of GBs and you will need the same amount again or even more to successfully update the Mac.

Some of your apps will no longer work

One of the new changes in the latest version is the drop of 32-bit app support. That means any old application which was built for a 32-bit system will no longer be compatible with the operating system. You won’t be able to run it until the developer updates to a 64-bit format which will most probably not happen if you are using old apps. This change might sound bad or strange, but it allows the developers to create an application just for architecture system and they won’t have to think about making the apps backwards compatible.

What will happen with the 32-bit Apps?

Based on Apple’s habits, they will let you know which applications will no longer work before you start the installation. They do the same when you updated your notes app in iOS 12 or your reminder app in iOS 13. They don’t want to create a problem, so they will definitely tell and alert you about this new change. After you finish updating, your apps might still be in the system, waiting for an update, or Apple can decide to delete them and only keep the personal data associated with the app. But I don’t see this happen. They know you need to know what stopped working and what you have to update.

 

How to prepare

You can either wait for the update and see what is going to happen, or you can just look around your apps, and most precisely at the small and old ones downloaded from the internet and not from Mac’s App Store. These apps are most probably using the 32-bit architecture. You can double-check by going to the official website and check these details. Maybe you can also update it, so you won’t have to do it later. You will also need to get used that from now on not all apps from the internet will work on your Mac. You probably still see incompatible apps which were built for older macOS versions but now you won’t be able to install them at all.

 

Many iOS and iPadOS Apps are coming to Mac

You might not like the news about the drop of 32-bit systems, but you might like some of the other features. With project Catalyst, Apple is bringing iOS and iPad apps to macOS. That means the developers can update their apps very easily and allow you to download them on the Mac and enjoy them as you do on the mobiles. This could bring millions of applications from iOS and iPadOS to Mac’s App Store and will fill the gap left by the old 32-bit apps. And if you are interested, all iOS apps are 64-bit. Apple dropped the 32-bit on iOS in 2017.

 

Other new Apps on Mac

macOS will also receive a new Reminder, Photo and Notes Apps. These will become similar to what Apple already introduced in iOS 12 and 13. The iTunes app will be removed and replaced by 3 other apps, Music, Podcast and Apple TV. They will most probably be imported straight from iOS, so you won’t have to re-learn anything about them. And one more change in the Mac Apps is the “Find my” app which combines “find my iPhone” and “find my friends” services into a new Application.

Summary

In macOS Catalina, all 32-bit apps will no longer work until you update them if an update is available. Apple will allow the developers to publish iOS and iPad Apps into Mac’s App Store. New or updated apps are getting released on Mac and these are Reminder, Photos, Notes, Music, Podcast, Apple TV, “Find My”. And the iTunes app will be removed. All of these will most probably be available at the end of October 2019.
