Several reasons can cause apps on Mac Pro to freeze. For a start, an app may freeze by itself, or at times, it may cause the whole system to freeze with it. Here are a few reasons why this could be happening:
- Apps freezing in the background of the Mac Pro
This may be a result of several apps running in the background. Some that you even did not open, but just started on themselves. Most likely, they are set to start automatically in your featured startup items. If this is the case, and it happens time after time, you may need to check these apps running in the background and set them not to launch on startup.
- Processes freeze in the background
This is not the same as an app freezing. Several processes may be running as a result of an app or it could be that system processes run by themselves thus causing the Mac Pro to freeze.
- Too many apps and processes running
This is similar to the preceding issue above. The difference is how many apps and processes are running. Therefore, depending on your Mac Pro’s hardware capacity, you can read on how to fix the issue.
- The Mac pro system is cluttered with junk to run even simple tasks
This is easy to fix since you can use an app to better optimize your Mac Pro. One such app, for example, is CleanMyMac X. This will require you to scan and delete things you do not need consequently resolving your freezing problems.

- On your Mac Pro’s keyboard, hold down the Option key so that Quit in that menu changes to Force Quit.
- Select Force Quit.
- The frozen app instantly closes.

How to Fix Mac Pro’s Freezing Apps:
Start by checking the apps that run in the background when you start up your Mac Pro. To do so:
- Head over to Settings, then Users and Groups, then to Login items.
- Secondly, uncheck or unselect all apps, as one or more may be the cause of the freezing issue.
- Restart your Mac Pro and launch the Activity monitor to see the programs or processes running.
You can find the Activity Monitor by typing it in the Launchpad or searching through the Spotlight Search. You can also use Finder in the Applications to access the Activity Monitor by going to Applications > Utilities folder > Activity Monitor.
On the Activity Monitor, you will be able to see several processes in each tab. However, you should focus on the Memory and CPU tabs. Click on the percentage icon (%) to see the processes and their running states on your Mac Pro.
