Some Mac users really enjoy full screen mode for apps and windows, so much so that they might want to make Mac apps open in full screen mode automatically.
While there is no system wide setting in Mac OS to make apps default to opening in full screen mode, there is a workaround trick that will allow many apps to open directly into full screen mode on the Mac.
The best way to make Mac apps default to opening in full screen mode is by changing your app usage behavior a bit, combined with an adjustment to a Mac OS system setting. The end result will be that, at least with many apps that support full screen mode, they will relaunch directly into full screen mode on the Mac. Let’s review how this workaround approach works to achieve the desired effect of launching Mac apps directly into full screen mode.
How to Make Full Screen Mode the Default When Opening Mac Apps
This is a two step process.
First, we’re going to make a settings adjustment in Mac OS system preferences that will allow Mac apps to resume their prior state they were in prior to quit.
- Go to the Apple menu and choose ‘System Preferences’ and then go to ‘General’
- Uncheck the box for “Close windows when quitting an app”
- Close System Preferences
This setting basically makes it so that if you quit an app, windows within that app will not close automatically, and instead they’ll re-open to where you left off. This setting is essential if you want some Mac apps to default to opening into full screen mode.
Second, you’ll need to change app quitting behavior. If you’re accustomed to closing all the windows of an app when or before you quit that app, you will need to stop doing that. Instead, place an app into full screen mode (like Safari for example), and when you’re done using that app, quit it while the active full screen window is still open.
- Open an app and place it into Full Screen Mode as usual (for example, Safari)
- When finished using that app, leave the full screen mode window active, even if it’s a new blank document or webpage, it must have an active full screen window left open
- Quit the app as usual, while that full screen window is active, and do not discard any open windows
- Upon relaunching that Mac app, it will open directly into Full Screen Mode by default
- Repeat with other apps as necessary
Assuming you followed the steps correctly, and you continue to quit apps while that app is still active with a window in Full Screen Mode, when relaunching the app it will be immediately in full screen mode on the Mac.
Putting it All Together: Relaunching Mac Apps Directly Into Full Screen Mode
For this to work properly, you have to follow the above sequence:
- You must quit the app while the apps primary window is still in Full Screen Mode
- AND, you must have disabled the “Close Windows when quitting apps” feature in Mac OS system settings
The system setting change is critical, because it causes Mac apps to basically resume their they left off upon relaunching. This means if you had previously enabled the “Close windows when quitting apps” feature in Mac OS so that app launching behavior is like what it used to be in older versions of Mac OS, then you’ll have to disable it.
Of course you can also just use your Mac apps as you always have, quitting and resuming whether in Full Screen Mode or not, and just get accustomed to making a window full screen on the Mac either with the use of a keyboard shortcut to enter and exit Full Screen Mode in Mac OS, a menu option, or the green button to toggle in and out of full screen mode, but that’s up to you, and obviously it won’t be automatic.
This trick works with all Mac apps that completely support Full Screen Mode in Mac OS, like Safari, Mail, Messages, Terminal, etc, but it may not work as well with some apps that aren’t designed to be used in full screen mode, and it definitely won’t work in any app which doesn’t support the feature to begin with.
So that’s the workaround to attempt to default to open Mac apps into full screen mode. For now that’s the best method to achieve that result, but perhaps a future version of Mac OS system software will offer a universal settings toggle somewhere in system preferences that allows Mac apps to default into full screen mode. There could be other options out there too, so if you know of another method of launching Mac apps directly into full screen mode, share them in the comments below!
