It is very unusual for an application to not function on Mac since the device is effectively optimized. The reasons behind these issues are very scarce, but the most prominent reason can be a disk permissions error. It happens when you are using OS X Yosemite or an old version of OS on your Mac. The disk permissions are the flags set for every item within the file system. They are the one that ensures an item can be executed, written or read. If due to some problem these permissions fail to attempt their work, then the application in the Mac won’t start, and the other reason for the interruption in the application can be the app preference. Here is the fix for all these issues:

Fixing the OS X Yosemite

As discussed above, the previous version of OS X has file permissions that are set wrong. This issue occurs when you update or install an app or maybe when you are using a copy version of OS X, and you try to update it. So here are the steps to fix this problem. If you want to use this method on your Mac then follow these steps:

First, try to repair the disk permissions, all you have to do is Open Disk Utility ...
... and open the Repair Disk Permissions option.
There is also an option to get proper assistance from your Mac, just click on Using Disk Utility to Repair Hard Drives and Disk Permissions.
There is another set of the linked files that you need to check. You need to run the Mac Troubleshooting for this. Reset User Account Permissions and it will guide you towards the process of fixing user account permission.
Fixing App file Permission Issues: OS X EI Capitan

The compatibility issue can be the problem for the OS X EI Capitan, so here are the steps to fix the issue in the OS.

The simplest step is that you can visit the website of the app developer and check if there is any script for guidance or steps about compatibility with OS X.
You can fix it by updating the app that is not working.
Fixing Preference Files

The corrupt files in the app’s preference are known as plist, so this can also be the reason for app interruption.

Here are the ways to fix app interruption issue occurred by plist file:

You need to reconfigure the app’s preference.
Then, simply delete the preference file of plist file that is causing the problem.
Locating the App’s Preference File

Most of the plist files are in the /Library/preferences folder. So by opening the library folder, you can fix this problem as well. However, the folder is hidden so here are the steps to fix the issue regarding app interruption:

You can check online how to open the library folder, search “OS X Is Hiding Your Library.”
Now, open the library folder.
Open the files ending with .plist and the preference file will be in com.developer_name.app_name.plist this format.
If you are searching the preference file for the Safari, then it will be com.apple.safari.plist in this format.
Once you find the file, close the app if it is running.
Move the app’s plist file towards desktop; this is the file that is needed to be restored.
Again open the app in question.
