The interaction of Minecraft's built-in fullscreen mode and macOS fullscreen can glitch the game window
The bug
Since snapshot 13w47c, Minecraft has support for native fullscreen (using the green button in the title bar) on macOS; a later update also allowed control+command+F to toggle this. However, Minecraft's built-in fullscreen mode, accessible through video settings or by pressing the F11 key (possibly with fn or ctrl also held down; see also MC-268226), can be toggled independently of this. Toggling these two features in a certain order can lead to the Minecraft window being black, blurry, unresponsive, without a title bar, partially split into a separate "java" window, and/or otherwise glitched.
How to reproduce
- Launch the game. Disable Minecraft fullscreen if it is enabled.
- Activate native fullscreen.
- Activate Minecraft fullscreen. The Minecraft window switches to a desktop space and blocks out the other content, deactivating native fullscreen in the process; this is as expected.
- Reactivate native fullscreen using ⌘⌃F. Visually, nothing will happen.
- Deactivate Minecraft fullscreen. You may need to try this a few times. The screen may have visual glitches. (In some cases these can be fixed by switching to another application and back.)
- Play around a bit more. See if you can get the Minecraft window to a similar state as in the screenshots below. If you get a window which is partially black or blurry, activate Mission Control (F3); you can see that the black/blurry bit is a separate window called "java".

Native fullscreen on OS X and F11 don't mix
This week's snapshots added support for native fullscreen (using the button in the title bar) on OS X. However, the F11 key (fn F11 on some keyboards) still toggles the old fullscreen feature, which causes weird behavior when used in combination with native fullscreen:
Steps to reproduce:
- Launch the game.
- Activate native fullscreen.
- Activate F11 fullscreen. The screen seems to switch to the Desktop space, but then draws fullscreen Minecraft over it
- Deactivate F11 fullscreen. Minecraft is back to window mode.
- Activate native fullscreen. Minecraft is now offset (there is a black border on the top and right side of the screen).
- Deactivate native fullscreen. The game does not adapt to the smaller window size.
An easy fix for this would be to change the F11 key so that it also toggles native fullscreen on OS X. (Also it would be nice if Ctrl Cmd F would toggle native fullscreen as well, since that's the keyboard shortcut other apps use.)

Just want to add to this, you don't need to necessarily remove the Fn+F11, but making command+control+f toggle fullscreen is enough.

However, Minecraft's built-in fullscreen mode, accessible through video settings or by pressing the F11 key (possibly with fn or ctrl also held down; see also
MC-268226), can be toggled independently of this. Toggling these two features in a certain order can lead to the Minecraft window being black, blurry, unresponsive, without a title bar, partially split into a separate "java" window, and/or otherwise glitched.How to reproduce
- Launch the game. Disable Minecraft fullscreen if it is enabled.
- Activate native fullscreen.
- Activate Minecraft fullscreen. The Minecraft window switches to a desktop space and blocks out the other content, deactivating native fullscreen in the process; this is as expected.
- Reactivate native fullscreen using ⌘⌃F. Visually, nothing will happen.
- Deactivate Minecraft fullscreen. You may need to try this a few times. The screen may have visual glitches. (In some cases these can be fixed by switching to another application and back.)
- Play around a bit more. See if you can get the Minecraft window to a similar state as in the screenshots below. If you get a window which is partially black or blurry, activate Mission Control (F3); you can see that the black/blurry bit is a separate window called "java".

Oh, sorry, I didn't see that one.. Probably because I was only looking in the "e" snapshot.
But the procedure to reproduce the bug isn't quite the same though. You only need to press the fullscreen icon in the title bar, and then I get the black bar. MC-40597 is a bit longer, and a little different, but i guess you could call it a duplicate. 
On OS X, there is a workaround if you're in native fullscreen (see MC-40597): switching to a desktop or a different fullscreen app (at least using the touchpad gesture, other methods like keyboard shortcuts not tested) will activate the pause menu.

Please reopen. This is NOT a duplicate of MC-40597. I'm using OS X 10.6.8. There's no "native fullscreen" on my system. It doesn't have anything to do with that. This problem didn't exist for me in previous snapshots, either.
Dupe of MC-40597
Do you have a technical reference to assert that, or can you demonstrate other apps that behave in this way where it is deemed to be the correct behaviour?
Other apps maximise themselves to a space which slides across the screen when you tab back/forth. This is the same behaviour as if you were pressing the green maximise button with Minecraft, and in fact, Minecraft will behave correctly under these conditions and Alt-Tab will "slide" across.
However, when F11 is used, a different type of full-screen is happening which is causing Minecraft to minimise to the Dock when you Alt-Tab. So it would be more correct to say that "This is just how MINECRAFT works" and that is why it is reported as a Minecraft bug.

Is this the same issue as MC-40597?
Switching windows using Cmd+Tab is only broken if you are using Minecraft's built-in fullscreen mode. More detailed behavior is described in the table below.
| 1.16.5 | 1.17 | |
| Minecraft's built-in fullscreen | Cmd+Tab partially works.  You can tab out of Minecraft, but you can't tab back into Minecraft due to MC-132029. |
Cmd+Tab doesn't work.  Here's a video: MC-228486.mp4 (In the video, the "java" icon is Minecraft; see |
| macOS's native fullscreen | Cmd+Tab works.  |
Cmd+Tab works. |
| Windowed (not fullscreen) | Cmd+Tab works. |
Cmd+Tab works. |
By "Minecraft's built-in fullscreen", I am referring to the fullscreen mode that can be toggled in Minecraft's video settings or alternatively by pressing Fn+Ctrl+F11. (Ctrl might be optional for you depending on your keyboard settings in system preferences.) By "macOS's native fullscreen", I am referring to the fullscreen mode that can be toggled by clicking the green circle on the upper left corner of the window.
This is probably related to MC-40597, and maybe also to MC-170545.

Resolving this as a duplicate of MC-40597, as these tickets seem to describe the same issue

Would MC-40597 describe your issue? If not the same, they are at least relevant to one another.
Well, there shouldn't be two fullscreen modes because that would be just stupid. So either remove the F11 shortcut for the original fullscreen or make that toggle the OS X fullscreen. Anything else is totally confusing and buggy.
Right now there is no way to 'set' the 'new' fullscreen mode. I'll ask LWJGL if they can add it, and if so, we can use that instead when pressing F11.
And what about the fact that if you enter "minecraft" fullscreen while in native fullscreen then exit it, the window is incorrectly sized and shows the bar at the top.
[Mojang] Grum (Erik Broes): have you heard back from LWJGL yet? If not, it might be better to just remove the F11 shortcut, as suggested by Finn Wilke.
Here is the LWJGL thread: https://github.com/LWJGL/lwjgl/issues/83
@[Mod] Ezekiel (ezfe): That repo seems to be abandonned. To fix this, Minecraft needs to update to LWJGL 3.
Yes I know, that is mentioned in the ticket. I forgot to mention it here though.
Affects 1.12 Prerelease 5
Can someone please check if this is still an issue in the latest snapshot 17w43b?
Native fullscreen currently crashes Minecraft on macOS, so this is blocked, i think
It is not native fullscreen but F11 fullscreen that crashes Minecraft.
My mistake. To the same effect.
Is there a ticket for the crash? I have not found one so far.
So what's the status of this ticket with the recent snapshots now?
I do not have access to macOS 10.13 “High Sierra”, but on 10.12 “Sierra” and 18w07c, this is now a crash bug:
There's some discussion here about forcing a crash however, this has not been tested on the latest snapshots as far as I know.
The issue of F11 and a maximized window is still a problem.
What is happening is that if you use the native window Maximize/Minimize button, Minecraft window will max/minimize but when you press F11, the game itself seems to maximize to full screen. This means if you have already maximized your window using the native buttons, then maximize the game again using F11, the game is "stranded" on a maximized window space. This can be seen if you F11 again to go back to windowed mode. You'll notice that your game returns to a window size, but stays in the same resolution and for some reason moves across to the right.
I will attempt to demonstrate in a video but the STR are:
To get out of this mess you need to use the green window button to return the whole application's back to windowed.
The above was tested in 1.13-pre5. Should this bug remain open or should I file a separate bug for it? @Mods?
Not necessary to make a separate ticket.
Affects 1.13-pre6
Affects 1.13-pre7
Also note that after step 4, Minecraft is back in windowed mode but the desktop is black, suggesting that it has become stuck inside a macOS ("Space")
Affects 1.13-pre10
Affects 1.13
Affects 1.13.2-pre1
Affects 18w43a
Affects 18w43b
Affects 19w05a
Affects 19w12a
Is this still an issue in 1.14.4 or later?
Yes, this is still an issue
Affects 1.20.4
I can't reproduce this in 24w05b on Sonoma 14.3. Do I need to do something in System Settings to get this to happen?
Never mind, I forgot that the fullscreen toggle was ctrl+F11 and not just F11. That info should be added to the description here.
That being said, I'm not sure that there's much of an issue here. ctrl+F11 is just a shortcut to the Minecraft fullscreen mode, and the behavior of this mode seems entirely understandable to me. It could be argued that this mode should be removed from Minecraft Java Edition on macOS in favor of macOS fullscreen, but that would likely be a feature request. Additionally, ctrl+cmd+F does now work for toggling macOS fullscreen. If there's any bug here it's that you have to press ctrl for the fullscreen toggle even though the key binds screen just says F11; I may make a separate ticket for that.
Actually, I think this issue has been resolved. I'm unable to make the game crash and while it's super glitchy while switching into Minecraft fullscreen it doesn't seem to cause any real problems.
When you said you reproduced it, what do you mean by "it"? Just going into the secondary fullscreen? I'm in 1.20.4
Not sure I understand your comment but it seems like we agree that steps 1-4 of the description are WAI and steps 5-6 are no longer an issue, while the issue with ctrl is now covered by
MC-268226. This being the case, a WAI here seems appropriate.I was experimenting a bit more and was able to reproduce the issue or a variant on it that can take over this ticket.
In some versions of the game I'm able to crash the game and in others I'm able to end up with a frameless window (no title bar with close/minimize/expand button).
If F11 works for you, use that. I used the Full Screen button in Video Settings to accomplish this:
At this point, my computer screen is mostly black/or blurry. I press command+control+F one more time and the game exits full screen but has no window controls (close, minimize, expand etc.). The window is sometimes larger than my screen and sometimes smaller.
In prior versions (1.19) this crashed the game.
I see. I was also able to reproduce this and took a couple of screenshots using shift+cmd+4+space.
Here's a final screenshot showing the window with the title bar gone. Also, requesting ownership since the current owner has been inactive since 2020.
