1. Uninstall the Program That Is Causing the Error

Every computer program requires certain things to function effectively, and if the host environment is not up to the task, then it might cause problems.

Thus, if you started experiencing the error code 102 after installing a program on your Mac, the best option might be to remove it altogether. This is how to uninstall apps on a Mac:

  3. In case the app is not in a folder, or doesn’t come with an Uninstaller, drag it from the Applications folder to the

2. Clean Associated Preference Files

macOS uses preference files to tell applications how they should work on a device. If the preference files are corrupted, the error code 102 may appear.

One scenario that causes preference files to be corrupted or overloaded is by uninstalling programs through the Trash. This method does not clean the system well and it has the unintended consequence of making useless files to accumulate. Here are the steps you can take to remove the preference files after removing an app:

  1. Navigate to Finder > Go > Go to Folder.
  2. Type “/Library/” in the search box, and press the Return key.
  3. Open the Preferences folder and find the preference files that are associated with the app that you have just removed. Drag them to Trash.

3. Clean Start-up

Whenever your Mac reboots or starts, a dozen or so applications will also launch automatically. This is all good if the particular applications are of use to you, but if they are not, they are just wasting precious computing resources. At the same time, if any of the programs that is supposed to launch automatically is problematic, it may cause the error 102.

If this is the case, you can opt to remove the problematic app from the list of start-up items. Here is how to disable a start-up item on a Mac:

  1. Click on the Apple icon and navigate to System Preferences on the sub-menu.
  2. On the Users & Groups pane, you will find a list of the apps that launch automatically every time you launch your Mac.
  3. Select the item that you want to remove. Click the minus sign button to remove it.

4. Clean Junk Files

There is no way of preventing junk files from accumulating on your computer because every time you use it, some ‘history’ of the usage is preserved. The accumulation of these files can cause all manner of problems on your computer, including the error code 102. To clear cache on a Mac, take the following steps:

  1. Navigate to Finder > Go to Folder.
  2. Type in ~/Library/Caches and hit enter.
  3. Go into each of the folders and clean out all the cache.

Cleaning the cache this way will provide you with an additional hard drive space. It will also remove problematic preferences files that may be responsible for the error 102 on your Mac.

5. Check for Hardware Damage

Sometimes, your Mac may be behaving the way it is because of a hardware problem. Did it fall? Is the RAM okay? Are the hard drives damaged? These are some of the questions that you should be asking yourself, should all else fail.

You can get some answers to these questions by performing a hardware diagnostics test. Here is how to conduct one:

  1. Disconnect all external devices except the keyboard, mouse, the AC cable, and Ethernet cable. If you don’t disconnect all other devices, the Apple Hardware Test might not help you.
  2. Place your Mac on a hard, flat and stable surface.
  3. Shut down your Mac.
  4. Turn your Mac on and immediately press and hold the D key on your keyboard. Keep holding this key until you see the Apple Hardware Test icon.
  5. Select your preferred language and click the right arrow.
  6. To begin the test, press the letter T on your keyboard or Return. You can also select “Perform extended testing” before commencing the test. This will lead to a more thorough test.
