Some apps are just meant to be enjoyed in full-screen modes, like movie players or games but some Mac users prefer to open apps in full screen because of their personal preferences. Full-screen mode in Mac gives you the maximum working space while minimizing distractions since the dock and the status bar are hidden so allowing to open an app on Mac, automatically, in full-screen mode can prove quite helpful.

But the problem is that there is no system-wide setting in macOS that lets apps open in full-screen mode by default. However, there’s a workaround, the Apple app opener, that allows your apps to open straight into full-screen mode. The easiest way to open Mac apps in full screen by default is to slightly change the app usage behavior and combine it with an adjustment. With this, apps that support full-screen mode will launch directly into full-screen mode when you open them and this article will show you the step-by-step guide on how to open an app on Mac directly in full-screen mode.

How to Open an App on Mac in Default Full-Screen Mode

Macs have a built-in setting that allows apps to resume or save their state before closing. When the app is re-launched, the application remembers the previous setting and will open itself in the same state. It means that any documents or windows you previously opened will be captured and relaunched. This feature also captures window settings like full-screen mode, which is what we want to achieve in this tutorial. This process is made up of two parts.

First, you need to adjust the settings under System Preferences so that Mac apps will resume their prior state before they were re-launched. To do this, follow these steps:

• Open the Apple menu  and go to System Preferences > General.
• Uncheck Close windows when quitting an app.
• Close System Preferences.

This step is crucial because it lets you open your app where you left off. So when you quit an app, the windows within that app will not close, but will instead re-open and resume from its state before the quitting. This step is essential if you want to open your app in full screen by default.

The last step in this process is to the change the quitting behavior of the app. Instead of closing all the windows of an app before quitting, now you have to quit the app with the full-screen window still open. For example, if you’re using Safari, don’t close all the tabs when you quit the app. Leave one tab open even if it’s blank. Here’s the step-by-step process of closing an app so that it reloads into full-screen mode.

• Open the app and launch into full-screen mode by clicking the green button located at the upper-left corner of the window.
• When you’re done using the app, don’t close the window – leave the full-screen mode active. You can close some of the tabs or windows, as long as you leave one open.
• Quit the app as usual, while the full-screen window is still open. You can quit the app by clicking from the menu bar, by pressing Cmd + Q or by right-clicking the app’s Dock icon.
• When you re-launch the app, it will launch directly into full-screen mode.
• Follow the same steps for all other apps.

This Apple app opener works for most Apple apps like Safari, iTunes, Photos, App Store and others. It also works for some third-party apps like Skype and Microsoft Office apps. However, several third-party apps don’t support full-screen mode. Photoshop, for example, doesn’t have a full-screen mode. It only maximizes the window by taking up the available monitor space. You’ll know when an app is in full-screen mode when the menu bar is hidden.

By following these steps for all your apps, you’ll be able to open them into full-screen mode without doing anything else directly. The process might be a bit complicated and troublesome because you have to do all these for each of the apps, but it pays off in the end because you only have to set it up once.

Opening Apps at Startup

You can also open specific apps when you log in so that they’ll be ready when you open your Mac. For example, if you always use Microsoft Office apps and Safari when you work, you might want them to launch at login, so you don’t have to open them manually. Take note that startup applications mean longer boot up time. So if you don’t want to wait for lengthy startup time, you might want to limit the number of apps you want to launch during login. To set up your startup applications, follow these steps:

• Go to System Preferences > Users & Groups.
• Click the Login Items tab.

• Click + at the bottom of the list of applications.
• Choose the applications you want to add to the list.
• Close the window.

Shutting Down Correctly

To make sure that all of these changes are applied, you have to make sure that you are shutting down your computer and closing your apps correctly. When you shut down your Mac, you have the option to reopen all of the apps and windows that you have open before the shutdown. Whatever you’re working on and whatever apps you have open will be re-launched once you log back in. To do this, tick off the box that says ‘Reopen windows when logging back in’ in the Shut Down dialog.

Another thing you have to remember with this Apple app opener is how to quit your apps correctly. We have mentioned earlier that you should not quit the app entirely and that you should leave at least one window open. It is so that your app will re-open in the same state during quitting, letting you quickly pick up from where you left off. This Mac app opener tutorial allows you to open your apps in full-screen mode without having to do anything else. The advantage of this workaround is that you can choose which app you want to apply this setting to, and leave some apps to open as is.

What are startup items?

Startup items, or login items, are services and applications that launch every time you start your Mac. These are applications that sneak into startup items without notice, never asking if you need or want them there. This way you may end up with a dozen apps launching as soon as you turn on your Mac, weighing heavily on its processor and memory capacities and slowing it down. Such items can increase your Mac’s startup time and decrease its performance.

Plus, sometimes when you remove an application or a service, it leaves a login item with a broken link. These broken login items are completely useless, cause unwanted messages, and waste your Mac's resources (because they look for non-existent applications). Whether you're running macOS Catalina or El Capitan, or earlier — it's all the same, so just read on.

So, let's go over how to take control of login items, and how to get rid of unwanted, broken or hidden startup items.

How to disable startup programs?

Do you want to stop programs from running at startup? There’s an easy way to remove programs from startup and get your Mac to load faster on launch. The fastest way to turn off startup items on Mac is an app like CleanMyMac X.

1. Download CleanMyMac for free.
2. Launch the app.
3. Open Optimization tab.
4. Click on Login items.
5. From the list of apps, disable the ones you don’t need on startup.
6. Done!

How to change startup programs manually?

Disabling Mac startup programs is possible manually. Therefore, if you have some time and would like to do it yourself, follow the steps below.

Your login items are listed in settings. One of the easiest ways to control startup items is inside System Preferences > Users & Groups.

1. Open System Preferences.
2. Go to Users & Groups.
3. Choose your nickname on the left.
4. Choose Login items tab.
5. Check startup programs you want to remove.
6. Press the “–” sign below.
7. You’re done.
8. If you need to add an item back, press “+” and choose the app you’d like add.
9. Then restart your Mac to see the changes.

How to fix broken startup items?

Broken Mac startup files are left there because some part of apps are left on your Mac long after you’ve moved the app to the Trash. To get rid of these parts and to fix your startup, you’re going to need CleanMyMac again. First, you need to check if they’re among startup items and disable them if so. You can do it following the instructions above. Then you need to remove app leftovers. CleanMyMac works fine on macOS High Sierra and earlier OS.

1. Launch CleanMyMac.
2. Choose Uninstaller tab.
3. Scroll through the list of apps.
4. If you spot any app that you’ve deleted, check them.
5. Delete the app leftovers you’ve chosen.

You can also find and remove broken login items with the help of System Junk module:

1. Choose System Junk tab.
2. Click Scan.
3. Review details and click Clean.

Finally, you need to clean your macOS startup items through launch services:

No Apps Opening On Macbook

1. Open Maintenance tab.
2. Choose Rebuild Launch Services.
3. Hit Run.
4. Done.

Once you do it, all broken app data on your Mac will be fixed.

Remove daemons and agents from startup process

If speaking of files, first go to the system folder /Library/StartUpItems. Here you’ll find all the startup files that are being launched with the system. You can delete the login item you think is necessary if you’re totally sure what you are doing.

Also, the /Library/LaunchDaemons folder contains a bunch of preference files that define how the application that is being launched along with the system should work. You might want to delete some of these files as well if you know you don’t need them and removing them is safe.

No Apps Opening On Mac Os

The /Library/LaunchAgents contains preference files responsible for the apps that launch during the login process (not the startup).

The above-mentioned folders contain app-related files. However, you can also check system folders to review whether you need some of the system applications to be running on startup:

Apps Not Launching On Mac

1. /System/Library/LaunchDaemons - note that besides preference files this folder contains other important system items that are recommended to keep untouched.
2. /System/Library/LaunchAgents - most probably, you won’t also find anything worth removing in this folder, however, keeping this location in mind might help you find files related to a problematic app that causes troubles on Mac startup. If you have a problematic application that messes about on login, you can try to trace it back from this folder.

But, if you’re looking for simple ways to remove login items, we suggest using a professional Mac utility. Download CleanMyMac X for free and make unwanted and broken login items a thing of the past.
