What to Do When Damaged App can't Open on Mac

What is scarier than an unresponsive app on any device, really? If your device got stuck, you can employ methods like restarting it, or waiting it out, as it usually works. Let's suppose your Safari app doesn't open on on your Mac but shows a bouncing Dock icon for the longest period boggling you to indefinite ends. This could be a complication but it's nothing to fear. This particular problem of Safari on your Mac, that probably runs on OS X Yosemite or previous version might be due to a disk permissions error. These are flags for each material in the file system. They could be on a strike for all you know!

To squeeze in a nut, the function of disk permissions is to allow the same materials to be read, written or executed. There are always permissions sought at the start of installation of an application and here in your case, that would be Safari. At times, these permissions meet with problems and that would result in the bouncing Dock icon and an app that never launches. At times, a plug-in fails to work, and this wouldn't entirely put the app off-stage but some part of it would refuse to work.

We are here to help you with some easy solutions to fix the problem of app unable to open. It's not as serious as it sounds and don't we all love to exaggerate! But, you have an app to open and you have a problem to fix, so let's do it.

Solution 1: Reinstall the application

Reinstalling the application is bound to be of great help as this can get rid of the problem in the process and help you achieve your goal!

You can reinstall the apps that are damaged and can't be opened in the following manner:

  1. Launch Apple Store application.
  2. Press down the Option Key and select Purchases.
  3. The apple logo appears soon after that.
  4. Delete the app or check for any updates. Select Install.

Solution 2: Modify Security Preferences

In some bizarre cases, especially after a backup or transfer session, there are chances that the permissions on the MacOS directory can become wrong. If so is the case, you might like to try a disk permissions repair quotidian with Apple's Disk Utility, located in Application/Utilities.

Following this, insert your Mac OS X installation disk, and restart while pressing down the C key. Once the start-up process is complete, select Utilities menu and choose Repair Disk Button.

You may follow these steps to fix the problem of permissions:

  1. Select the unresponsive application to get redirected to its source in the Finder.
  2. To access the option Show Package Contents, use the Action menu.
  3. Select the Contents folder in there and then look for MacOS folder.
  4. Modify the security options on this folder to lend it execute permissions. Type in the following command after opening the Terminal -sudo chmod 755.
  5. Once getting it done, drag and bring the MacOS folder to the Terminal window. Click return, and you will be asked for your administrator password and you have to enter it.

The MacOS directory will now provide read, write, and execute prerequisite for the owner, and this might have in the process also erased your problems related to damaged apps and not opening problem.

Solution 3: Clear Mac’s Cache files

Check each time, if your unresponsive application hitches off without any troubles on the deletion of all files that end with .cache. You can achieve this by following these steps:

  1. Click open a Finder window. Choose Go to Folder from the Go menu.
  2. Hit in ~/Library/Caches and click enter to get redirected to the page.
  3. Check off the boxes you wish to get rid of!

Solution 4: Upgrade prebinding

Through the following steps, if you can upgrade/update your prebinding, you may be able to open the unresponsive app.

  1. Sign in as administrator.
  2. Click open the Terminal.
  3. Get to typing, sudo update_prebinding -root / -force and select Return.
  4. When requested for a password, enter your admin password, and select Return once more. This process may take a few minutes and its completion is marked once the Terminal returns to a normal state.
  5. Type in Exit and select Return.
  6. Check the capability of the unresponsive application.

Solution 5: Hunger process in activity monitor

Check Activity Monitor to clear running applications in the background which take too much space in CPU. This might increase your chances of cracking the app open. This works just like a restart-session, and it may be your hero in disguise for the day.

  1. Open Activity Monitor.
  2. Take note of the process in connection with the unresponsive application.
  3. Quit it and try launching the apps once again.

Solution 6: Make a new user account

If you can make a new user account, do that and try launching the unresponsive app under this. If it works, then there is a user-specific bug that hit your Mac central to cause you brain-pain. You can also try deleting files with .plist and .cache at the end of the document name.

Solution 7: Look out for errant plug-ins

A few Mac apps like Safari and iMovie are known to be major victims of this criminal. Potentially, this can cut off your accessibility with the apps and therefore, to make sure, you may go through the following locations for any files that were added recently or any files infused with error messages that were generated once you tried to launch the app-


Technology is growing into a monster-sized king rapidly, if it hasn't already. Gizmos and golems get outdated in nanoseconds and new ones replace old ones like toys and guns in children's playhouse. Every second witnesses the arrival of tech-infused content, tech-ideas, and tech-everything, it has begun to mess with any sane person's IQ. This growing technology creeps in problems to rub in our face and frustrate us to no end. Like a door with a key, every problem has got their own solutions and that's exactly why it's recommended to take the key on your own and unlock your problem. We don't want anything other than a problem creeping in now, do we? (That was entirely literal!)
