Top 10 macOS Catalina Problems And Solutions – Updated 


In 2019, Apple users welcomed Catalina, the 10.15 version of macOS. This new system adds a lot of new features in macOS like porting iOS apps and many changes in Photos. Also, the process of free up space on mac has become much simpler.

However, despite a plethora of new features and applications, as usually happens with software updates, it is also normal for unexpected failures to occur. In this article, we explain the common problems with macOS Catalina and, of course, also explain how to solve these incidents.

Top 10 macOS Catalina Problems And Solutions

All Apple updates are first released in beta, the final versions are restricted in bugs. So, with each major update, it is recommended to make a backup of your Mac to keep your data. So that in case of a problem, you will be able to restore them. However, these updates are not exempted from bugs. This can range from a simple bug, just annoying, to a big one preventing you from using your computer. In fact, the latest Catalina version of Apple’s Mac operating system has been the talk of the town lately, and there are several reasons for this.

So in the following lines, we will share with you these problems and in particular, solutions to better enjoy the performance of your Mac.

1. Bluetooth Problems

If you are having trouble connecting accessories or Bluetooth devices to Catalina, you are not alone. The first step is to open the settings in the upper right corner of the screen, and then start the Bluetooth preferences menu. Click on the devices you are having problems with and repair them.

This should resolve most Bluetooth issues, but if you are still experiencing problems, you should open your Finder search and click OK on the menu. Select Go to Folder and type “Library  Preferences“.

If you prefer, you can also save a copy to an external flash drive before deleting it to be sure. Once the file is deleted, you will need to restart your Mac and try pairing your Bluetooth devices again.

2. Apps Problems

While Catalina introduces Mac users to a whole new world of iOS applications suitable for working on a Mac, older applications will no longer work in Catalina.

If you have these older applications, you may need to upgrade to newer versions of the Mac App Store when they become available, or you may have to wait for developers to release updates for these same applications.

3. Access to MacOS Catalina files

To enhance Catalina’s security, Apple has changed the way applications can access your files. When accessing a recently downloaded application, Catalina can open a pop-up window asking for permission to go through files or folders. If you have denied access and changed your mind, you can do so by opening the System Preferences application on your Mac in the Dock.

Then choose Security and Privacy, and click Files and Folders in the left pane. In the right pane, you’ll find a list of applications with their file access privileges. You can also click individual applications to make changes.

Once you have granted or revoked file access privileges, be sure to restart the application for the changes to take effect.

4. Catalina installation problem

This is a very common problem that always happens with every new macOS release. The installation doesn’t start or you face a blocking problem when installing Catalina. You will see that the screen remains blocked and that there is no progress during the installation.

On top of that, no matter how many times you restart your Mac and start the Catalina installation process again, you will always get the same error message. To solve this problem, make sure to reset the SMC, NVRAM or PRAM. You can also consider restoring your Mac.

5. iCloud problems on macOS Catalina

A very common problem with iCloud is that users are unable to download their files. You can try to download iCloud files separately but this can be really annoying if you have a very large library.

If you are about to set up iCloud, then you can expect another problem: not being able to accept the terms of use. The window keeps showing on the screen.

A fairly easy way to solve this is to go to “System Preferences” > “Internet Accounts” and click on the iCloud icon. From there, you will be able to accept the terms of use without encountering any errors.

6. Mail search malfunction

The mailbox can be in a total mess after an update. So, if you try to search with a keyword or the name of the sender or recipient, the application will only display the numeric number of results. This could be due to the new Spotlight integration. To resolve the problem:

Go to “System Preferences” > “Internet Accounts” and delete your email account. After that step, restart your computer and add your e-mail account to the Mail application again. U shall by then try searching for your e-mail and everything should work fine now.

7. Problems of slowdown and overheating on macOS Catalina

Normally, macOS Catalina should be faster since this is the last update. 32-bit architecture was one of the things that caused the operating system to slow down. Unfortunately, you can still expect your Mac to slow down and overheat.

However, there are many things connected that can cause your Mac to slow down. To eliminate this problem, disable the launch of your applications when you start a session on your Mac.

To do this, go to “System Preferences”, then “Users and Groups” and “Login”.

From there, you can select the applications you do not want to run when you log in and the only thing left to do is to reset the SMC.

8. Internet doesn’t work anymore after installing the Catalina update

If you attempt to push macOS 10.15 beyond the current system, then you may experience Internet connection problems.

A radical solution here would be to get rid of the Catalina macOS installation. It’s what’s best for your Mac and will most likely solve the problems. If you’re not willing to take such a risk, then restart your Mac.

9. Safari extensions bugs

While trying to make a transition to iOS-compatible extensions, Apple is gradually considering format support for a wide variety of web extensions. On Catalina, you’ll encounter .safariextz files that don’t work.

There is no solution to fix the missing extensions. If you can’t find a good alternative, then it is recommended that you switch to Chrome or another web browser.

10. The disappearance of the Dock on macOS Catalina

Most Mac users mentioned that the Dock disappeared from their screen just after the Catalina update. The source of this problem is still unknown. Some users think it has something to do with the PRAM reconfiguration, others say they encountered this problem when they tried to work across two screens.

To solve this problem, try pressing “Option” + “Command” + “D” simultaneously. If this action does not work with you, then follow these instructions:

  • Go to “Settings” > “Dock”.
  • Change the setting “Automatically hide/show Dock”.
  • Customize the position of the Dock on the screen.
  • Close the window and check that everything is now working normally.
