macOS will exit all background applications and running processes. In this way, it frees up RAM and CPU memory, reducing virtual memory size from the hard drive.

If the Apple Menu does not open or the Mac freezes, press and hold simultaneously Control + Cmd + press power button to start reboot. Or press and hold the Power button for about 10 seconds to restart the Mac.

Method 3: Update the software

When app updates are available, you will receive notification and update icons on the App Store.

Applications that you downloaded from the developer site may not have an automatic update mechanism. Some apps check for updates whenever a user opens the app, others check a fixed schedule or on demand. Your task is to find commands Check for Updates on the Help menu, Application menu, or Preferences window.

In addition, you can turn on the automatic update feature to update the application whenever updates are available.

Method 4: Check for compatibility issues

If the problem persists, you can fix a frozen, closed Mac application by checking that it is compatible with the latest version of macOS. Open Apple Menu =>About This Mac to check the macOS version you are using. Visit the application developer website to see if the application is compatible with the operating system you are using.

Also, try checking old 32-bit applications on the system. To do this, open Apple Menu =>About This Mac Then click the button System Report.

Scroll down the left pane, select Applications from the item Software. Wait for a few seconds to display the list of installed applications. In the right pane, find the column named 64-bit (Intel). Adjust the width of the column and then click the title to sort the list.

At WWDC 2018, Apple said macOS Mojave was the last version to support 32-bit applications. That is, if the application you installed is a 32-bit application, it is best to find other applications instead.

While developers support their applications on newly released macOS versions, bugs are inevitable, especially with early updates. Check the forums to see if other users have encountered the same error you encountered.

Method 5: Delete the Preference file

Preference files contain application settings, which include the necessary parameters for the application to work properly. If the preference file fails, the application may freeze, freeze or even corrupt the data.

Most preference files are located in the following Library folders:

– / Library / Preferences or / Library / Preferences

– / Library / Application Support /[App or Developer name] or / Library / Application Support /[App or Developer name]

– / Library / Containers /[App name]/ Data / Library / Preferences

According to the Apple developer documentation, preference files follow a standard naming rule called reverse domain naming system. Include the company name, application identifier code, followed by the property list file extension (.plist). For example, com.apple.finder.plist is the preferences file of the Finder.

Developers can use proprietary naming conventions, but focus on clarifying application names. For example, org.idrix.Veracrypt.plist is the preference file of the Veracrypt application.

To find the preference file of the application, the first step is to close the application, if it is already running. Open the Library folder and set the view to List view, then click Name column to sort the list of applications alphabetically.

Enter the application name in the Search box. To narrow the search results list, click the plus icon and set the 2nd row to System files are included.

Drag the preference file to the desktop. Because the server process runs in the background to maintain the entire preference structure, your task is to clear its cache to clear obsolete preference data. This way the application cannot use the old preference files and the application crashes, freezes.

To do this, first choose Apple Menu =>Log Out to log out and log back in. Next open Terminal and enter the command killall cfprefsd Click on it and press Return.

Another way to delete the preference file is to use AppCleaner. The free AppCleaner utility, designed to uninstall Mac applications without leaving any data, as well as delete preference files.

Download AppCleaner and install it here: Download AppCleaner

Just enter the application name into the AppCleaner, then uncheck the application, check the options, related settings and then click Remove.

Method 6: Clear application cache

All Mac applications use cache. Cache files store information that is frequently used, making the application more efficient.

If the memory file is corrupt or corrupt, it is likely that the application may be corrupted or not function properly. macOS will try to remove the corrupted cache files, but because the application cache files are hidden by nature, it is quite difficult to find problems arising from the cache.

The cache files are located in the following Library folders:

– / Library / Caches or / Library / Caches

– / Library / Containers /[App Name]/ Data / Library / Caches /[App Name]

– / Library / Saved Application State

The application name follows the naming convention of preference files. Close the application and find the application cache file or directory according to the specific path above. Once found, drag the files and folders to the trash. The application will reset the cache file automatically.

If the application displays a problem, you can clear the system cache. Open Terminal and enter the following command and then press Return:

sudo atsutil databases -remove

Enter the Admin password when prompted. After the process is complete, reboot your Mac.

A small note that should not delete the system cache in a bluff, only delete when the system or application has a problem. Cache memory helps Mac work smoother. Clearing the system cache means that the Mac will have to recreate them from scratch.
