How to check if apps will work in Catalina. MacOS Catalina will not run 32-bit apps at all, so the first thing to do is to check whether any of the apps you are currently using on your Mac are 32. MacOS Catalina apps not working. This is one of the macOS Catalina problems that trails back to macOS Mojave. As you’ve probably heard, app architecture knows 2 types: 32-bit and 64-bit. The 32-bit apps will not be supported on macOS Catalina, period. Sadly, they are not just some lo-fi indie apps, we are talking Photoshop!
MacOS Catalina is a significant upgrade and brings with it many improvements. But like every new OS, it’s not without its problems. One of those is that it causes some Macs to run more slowly than they did under Mojave. We know from the system requirements that it’s more demanding of resources than its predecessor, which is why it won’t run on some older Macs that could run Mojave. Happily, there are things you can do to boost performance. Here’s how to speed up Catalina.
macOS Catalina running slow: what do to?
To make macOS Catalina faster, you have to know what’s slowing it down. So do this:
1. Stop applications launching at startup
If the speed problem you’re having is that your Mac takes much longer to startup now that you’ve installed Catalina, it could be because you have lots of applications that are automatically launching at startup. You can prevent them auto-starting like this:
That’s the long way to get rid of startup items. There is a much quicker way that I prefer to use. CleanMyMac X has a tool that will quickly remove startup programs on Catalina. Here’s how to use it.
2. Remove Launch agents

Launch agents are similar to startup items except that they are not full applications, they are additional programs that add functionality to a related application. They launch at startup and could be a reason Catalina i
s slow to boot. Unfortunately, tracking them down manually on your Mac is difficult and time consuming. However, happily, CleanMyMac X can do it for you. Here’s how to remove launch agents. Apps Not Working And Mac Slow After Catalina Upgrade Kit
3. Close hundreds of tabs
Keeping lots of browser tabs open is convenient, but each one uses resources and they mount up. If, for example, a tab is displaying a page which has lots of animation or auto-running video on it, it will slow your Mac down. So close all the browser tabs you don’t need.
4. Take control of your Spotlight
If you have Spotlight set to its default, it will index every folder on your Mac, including those on external drives that are mounted. And indexing can slow down your Mac. You probably don’t need to search the contents of, say, your Downloads folder, or Library directory. Here’s how to exclude folders from Spotlight indexing.

Mac OS Catalina performance may get worse if applications on your Mac are out of date. Developers update applications regularly for all sorts of reasons. Most updates include bug fixes and performance improvements, so it’s important to keep them up to date. For apps that you download from the App Store, it’s easy. Just launch the App Store, go to Preferences and select Automatic Updates and your apps will always be up to date. For other apps, you’ll have to launch each one and check for updates from the application menu. Happily, there is a way you can update all your apps in one go using CleanMyMac X. Can you see how useful it is?
6. Shut down your Mac regularly
Modern Macs, especially MacBooks, MacBook Airs, and MacBook Pros are designed to be able to run and run without being restarted, thanks to their low power sleep mode. However, shutting down you Mac does more than just conserve energy. It clears temporary files, like swap files that are used as virtual memory, and it frees up RAM. Restarting your Mac regularly will keep it running quickly and smoothly.
7. Add more RAM
Sometimes, the only solution to fix macOS Catalina speed is to update your hardware. Adding more RAM will almost always make your Mac faster, whether it’s running Catalina or an older OS. If your Mac has RAM slots available and you can afford it, adding more RAM is a very worthwhile investment.
There are many tools that claim to speed up your Mac. Don’t believe apps that tell you that “your Mac is hijacked by virus” — this is a well-known scam. On the other hand, there are apps that help you better manage memory on Mac. For example, the app we’ve told you about, CleanMyMac X, has a tool called Speed that disables heavy-memory consumers. And this program is actually notarized by Apple.
If macOS Catalina is very slow, there are lots of ways you can speed it up. Follow the steps above and it should be running smoothly in no time.
