This guide will show you how to fix some of the common macOS Catalina beta problems that users are running into while testing Apple’s new version of macOS.
If you decide to test out the new software, we will help you fix some of the common macOS Catalina beta problems that are slowing users down without the need to wait for Apple to release an update. In case you get overwhelmed with the issues, you can go back to macOS Mojave fairly easily.
Here are the most common macOS Catalina beta problems and how you can fix them on your own, plus where to look for help.
How to Fix macOS Catalina Beta Installation Problems
There are two macOS Catalina beta installation problems that we’ve seen, both of which are pretty easy to fix. One of the big complaints is that after you join the macOS Catalina beta program it starts downloading the beta without many options. That’s because you are going to end up with an installer that you can use to choose the installation location. Don’t worry if you want to install the macOS Catalina beta on another volume or partition. Once you start the installer you can choose the location.
The other macOS Catalina beta installation problem that we’ve seen is from users who cannot install the beta. If you run into this problem you need to make sure you have enough space on the drive or volume you want to install to. This is by far the most common issue. Another thing you may need to do is simply restart your computer or restart into safe mode.
We have yet to see a “macOS could not be installed on your computer” (OSStatus error 2) like we saw with the macOS Mojave beta.
How to Fix macOS Catalina Beta Apps Not Working
Apps not working in the macOS Catalina beta is a common issue. There are many issues at play here and there are some things you can do to try and fix these issues.
If the app is working for other people, try uninstalling and re-installing the app. You can also check for updates to see if the developer is building in any additional support.
The next step is to look for a beta version of the app designed to work with macOS Catalina. This is still fairly early, but look on Twitter and support pages. If it is a specialized app that ties into the system there is a greater chance you will need to do this.
Finally some apps will not work on macOS Catalina if they are 32-bit. If you are running a 32-bit app you will need to look for an alternative or go back to macOS Mojave.
Here’s a list of apps that people say work with macOS Catalina and those that don’t,
How to Fix macOS Catalina Beta Internet Problems
While not widespread we’ve seen one report of the Internet not working on the macOS Catalina beta. If you run into this problem and are running an application called Little Snitch, uninstall that. It is not compatible with macOS Catalina, and prevented the user from being able to use the Internet. You can also update Little Snitch to the nightly update and you should be able to use it fine.
If you have WiFi issues, try turning the WiFi connection off and then back on, but thankfully we haven’t heard of any major issues yet.
How to Fix macOS Catalina Beta Side Car Problems
Apple now lets you use the iPad as a display for your Mac with a wireless or wired connection. If you cannot use Side Car on the macOS Catalina beta here’s what you need to do.
First off, you need the iPadOS beta installed on your iPad to use this. It does not work with iOS 12. So if you tried it and failed, go install iPadOS.
If Side Car performance is laggy or not working right, you can try connecting with a cable instead of wirelessly. Many users say this helps the performance.
Another thing to consider is that Side Car only works on newer Apple computers. This includes the following models;
- Late 2015 27″ iMac or newer
- 2017 iMac Pro
- Mid 2016 MacBook Pro or newer
- Late 2018 Mac mini or newer
- Late 2018 MacBook Air or newer
- Early 2016 MacBook or newer
- 2019 Mac Pro
If your Mac isn’t listed, you can upgrade to a new Mac, otherwise you will not be able to use the Side Car feature.
How to Fix Annoying macOS Catalina Beta Problems
If you cannot use the macOS Catalina beta with the current problems that you are experiencing, you can downgrade back to macOS Mojave. If you installed on a seperate partition or volume, you can simply switch back to macOS Mojave, but if you didn’t do that you will need to restore a Time Machine backup.
Here’s our guide on how to downgrade from the macOS Catalina beta to macOS Mojave so that you can go back to the latest stable version of macOS.
