Q: I have encountered an issue with macOS Catalina. How can I fix it?

“Recently, I updated my MacBook Pro to the latest macOS Catalina, but after that I have started getting several issues. Some of the apps are not working and the system keeps restarting. Can someone tell me how to fix these macOS Catalina bugs?”

Earlier in October 2019, Apple has released the latest version of macOS – Catalina (macOS 10.15). While the operating system is pretty advanced and has tons of new-age features, not every Mac user is happy with it. For instance, the above-stated query is posted by a macOS user about the malfunctioning of the system after upgrading to macOS Catalina. Apart from that, there are several other macOS Catalina problems that you might encounter. In this post, I will let you know about the 13 common issues with macOS Catalina and how to fix them.

How to Fix macOS Catalina Bugs or Problems

Since macOS Catalina is a newly released operating system, it is pretty obvious to face issues regarding its functionality or compatibility. Here are some of the commonly occurred macOS Catalina bugs that you can easily fix.

Problem 1: Can’t install macOS Catalina

This is the most common issue that Mac users complain about. Since so many people are trying to update to macOS Catalina, the process does not always yield expected results. There might be some compatibility issue with your Mac or the download could be stuck.

Fix 1: Is your Mac compatible with macOS Catalina?

Before you try to diagnose these macOS Catalina problems, make sure that your system can be supported by macOS 10.15 Catalina. You can just go to the official website of Apple to check the complete list of supported macOS Catalina systems.

Fix 2: Have a Stable Internet Connection

Since your computer would download a substantial amount of data from Apple’s servers, you need to maintain a stable internet connection. Simply check the Ethernet or WiFi connection on Mac before starting the installation.

Fix 3: Start the installation again

If the install is stuck and can’t proceed, then you can choose to restart it. The best way to do this is by restarting your Mac in the recovery mode by pressing Command + R during reboot. Now, click on the “Reinstall macOS” option from macOS Utilities of the Recovery Mode to proceed.

Fix 4: Check if Apple’s Servers are down

This might sound surprising, but even Apple’s servers might be down or be overloaded. You can just go to the Apple System Status page to check the current status of its servers.

Problem 2: Catalina Freezes on Reboot

A lot of users have encountered these macOS Catalina bugs in which the system freezes on reboot. It mostly occurs due to a conflict in the system or a problem with macOS firmware.

Fix 1: Restart Mac in Safe Mode

If there is an issue with Mac’s startup disk, then you can check it by booting it in the safe mode. This would discard the added features of Mac and would only load its core firmware components. To do this, just restart your Mac and hold the Shift key as it reboots. Let go of the key once Mac reboots and log-in to your account.

Alternatively, you can also launch Terminal and enter the following code to restart Mac in safe mode:

sudo nvram boot-args="-x"

Fix 2: Disconnect peripheral devices

A lot of Mac users have noticed that these macOS Catalina bugs occur due to some connectivity issues. Therefore, it is recommended to disconnect all the peripheral devices like mouse, Bluetooth speakers, USB drive, etc. from your Mac and restart it. If everything goes well, then you would be able to boot your Mac without any issue.

Problem 3: Catalina Apps not Working

With the release of Catalina, Apple has drastically changed the way apps run on a Mac. This has got a lot of users with macOS Catalina problems related to their apps. Chances are that your apps might not be compatible or haven’t been updated in a while.

Fix 1: Check if your apps run on 32 bit

With the release of macOS Catalina, Apple has made it official that 32-bit apps are no longer supported by the OS. That is, only 64 bit apps would run on macOS Catalina. Therefore, you need to check if the malfunctioning app is based on 32-bit if it doesn’t run.

Fix 2: Update the app

Chances are that you could be using an old or outdated version of the app. To fix this, just launch the App Store on your Mac and go to its Updates section. View all the apps that are available for an upgrade and tap on the “Update” button adjacent to them.

Problem 4: macOS Catalina is Running Slow

If your system has shown drastic changes after being upgraded to macOS Catalina, then you should be alarmed. Try to fix these macOS Catalina bugs as they can lead to serious issues in the long run. Mostly, this problem occurs due to the lack of space or a corrupt macOS installation.

Fix 1: Free-up Storage on Mac

If your Mac is already running on low storage, then the upgrade can even make it slower. To check this, just go to its home and click on the Apple logo > About This Mac > Storage. In case if your system has low or limited space, then delete all the unwanted data from it. Clear its Trash, uninstall the apps you no longer need, and simply delete the photos/videos that could be accumulating its storage.

Problem 6: Sidecar Problems on macOS Catalina

Apple has also introduced a brand new feature of the sidecar in macOS Catalina. This lets us extend or mirror our Mac’s screen to a connected iPad. Though, sometimes users encounter macOS Catalina problems while using the sidebar feature. There can be a connectivity or compatibility issue causing this.

Fix 1: If your iPad compatible?

Not every iPad model supports the sidecar feature introduced in macOS. Therefore, you can just go to the official website of Apple and check whether the iPad that you own supports the feature or not.

Fix 2: Update your iPad

From here, just choose to download and install the new update and try connecting it to your Mac again.

Problem 12: Storage filling up for no reason

Is your Mac taking a lot of space or an operation has started filling up its space for no reason? Mostly, the cause behind these macOS Catalina bugs is Time Machine as it can take too many and frequent snapshots of the system.

Fix: Restrict Time Machine Snapshots

The problem can occur due to frequent Time Machine snapshots that you can restrict manually. Firstly, launch Terminal on your Mac and enter the following command:

tmutil listlocalsnapshots / tmutil listlocalsnapshots /System/Volumes/Data

This will list all the available Time Machine snapshots. From here, you can manually delete the data you no longer need with this command:

deletelocalsnapshots <snapshot_date> </snapshot_date>

Please note that the snapshot date should be entered correctly with respect to the data you wish to delete.

Problem 13: iTunes XML file crisis

The iTunes XML files are mostly used by DJs and sound engineers for all kinds of reasons. Since macOS Catalina no longer supports iTunes, a lot of music apps have been affected. As of now, there is no fix to the iTunes XML file crisis. Ideally, you can just downgrade your Mac to a previous stable version like macOS Mojave so that you can access the iTunes XML files again.
