EXPECTED
The game should run in full resolution on MacBook Pro Retina (2880x1800 for fullscreen on 15").
OBSERVED
The game runs in half resolution: each pixel is displayed as 2x2 physical pixels. This affects both fullscreen and windowed modes. So the fullscreen resolution is 1440x900 on MBP 15.
I only play in fullscreen, so as a workaround I tried to force the correct resolution in options.txt (fullscreen:true, overrideWidth:2880, overrideHeight:1800) but it had no effect.
Options file attached. Log file doesn't seem to contain anything relevant so I didn't attach it.

Yes, it is of course only specific to MBP (though I heard the new iMacs and MBA will be Retina too).
But other games usually offer a choice to use full-resolution mode in fullscreen, even older games that cannot be aware of Retina. If I understand correctly, these games request a list of all possible video modes from the system. Minecraft looks like it doesn't do so, it uses the fullscreen video mode of what it perceives as a desktop resolution (which OS X reports as 1440x900 for compatibility with older apps), but NOT what it percieves as a maximum video mode supported by the system (which is 2880x1800).
So, there are two possible solutions:
1) Use maximum supported fullscreen resolution mode instead of perceived desktop resolution.
or
2) As a workaround, permit the user to force desired video mode through options.txt (or even better, in Video Settings menu).
The second option is maybe preferable because it can be used for other purposes: e.g. when a user wishes to play fullscreen but his system is too old/slow to let him be comfortable with his desktop resolution, so he may wish to use reduced resolution for fullscreen video mode.
If you haven't read it, Apple made it two by two pixel, or DPI 200 percent, which has an effect of quartering its resolution to 1440 X 900. If apple didn't do this, you could barely read the screen. Since it requires hacking the OS system itself, it wouldn't work without that.
No we actually use a hack to select the half-sized resolution because the full-one is not available as a DisplayMode through LWJGL.
Is this still a concern in the current Minecraft version 1.7.4 / Launcher version 1.3.7 or later? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases.
With the release of LWJGL 1.9.1 in December 2nd they've implemented proper retina support. http://lwjgl.org/forum/index.php/topic,5084.0.html This is a link that talks about it. It should now be possible to write Minecraft around retina. Namely, make the gui not see retina mode, but the rest of the game (the 3D part, so not the overlay or the HUD) see it as double the resolution and output properly. I'd love to see this in either a version 1.7.5 or version 1.8. Perhaps also add an option to turn retina on and off in the graphics settings for performance reasons, because all the extra pixels could definitely slow the computer down. This is especially relevant because Windows 8 is also going to support Retina/HiDPI modes and LWJGL will probably add the capability to turn that on soon too.
Can someone test this with Snapshot 14w02c since there LWJGL 1.9.1 is used ?
Since it looks like no one has responded in a long time I guess I will, I too experience this bug and it is quite frustrating. I have a late 2013 13inch rMBP running OS X 10.10.2 and java 1.6.0_65. The actual resolution of my display is 2560x1600 but fullscreen minecraft only runs at 1280x800, one half the length and width, or one quarter the total pixals (1,024,000 vs 4,096,000).
I got the latest launcher (1.6.11) and tested every single release (except for just one alpha and beta version) there is, the most recent being 1.8.2-pre6 and the issue occurs on every one of them.
Like someone has previously said many games allow you to manually enter your resolution, but I don't believe minecraft does (and changing the resolution you start the game at in launcher does NOT fix it).
One interesting thing to note is that when you let minecraft go to full screen by going into options the minecraft menus are blurry like the rest of the game. But when I tell the app to expand to full screen by clicking the little green button at the top of the window, the text appears twice as sharp (presumably full resolution) even though the rest of the game is still stays at half. The only way this make sense to me is if that my OS recognized the text on the menus as actual "text", then it would tell it to render twice as sharp as what it tells minecraft the displays resolution is, like it does on nearly all other applications.
I'm sorry for the lengthy comment but hopefully this helps
Ok so I've been looking around a lot and I have found two ways to work around the half-resolution bug. One is to get a app (I used SetResX) for the computer which makes everything (including the ui) run at the resolution of the display, not HiDPI mode. The other is actually by using the optifine mod for Minecraft, all you have to do is go into video / other settings and change the fullscreen option from default to what ever your screen resolution is (for me 2560x1600), how I've overlooked this option for a year is beyond me but at least I found it now. I tested optifine versions 1.7.10 HD_U_A4 and B1, 1.8.1 HD_U_B2 and C7, and 1.8.3 HD_U_A3 (latest) and it worked with all of them. Performance wise the app has slightly better fps than optifine when running the high resolution. On my testing world I got 40-55fps the optifine way, 45-65fps with the app, and 70-95fps with the default half-res (all test had optifine installed, but only the optifine way changed the res in the mod).
I found out the optifine thing just a few hours ago, I still can't figure out how I've missed it, but why I'm sharing this is that if someone could implement this thing with optifine into vanilla minecraft then this issue would be resolved. I don't know how to do it, I'm not developer, but I'm sure someone could figure out.
Affects 1.9.3-pre3.
Apparently this hasn't been mentioned in the thread, but the JVM flag `-Dorg.lwjgl.opengl.Display.enableHighDPI=true` WILL trigger correct behavior from LWJGL, including correct mouse movement, but the existing hack causes this: http://puu.sh/pk9Xo/1423a37f55.png.
@Xor Boole Yeah, the issue is that Mojang hasn't activated that variable and then adjusted the code to handle the change properly.
Affects 1.10.
Fixed in 17w43b.
The fix for this issue has caused issue for me.
This resulted in minecraft using the native screen resolution on my old Retina Macbook Pro instead of the faked half resolution. while this suits those who have computers with enough performance, I preferred and still prefer the lower resolution scaled up, as this was a lighter load on my computer.
since 1.13 any gaming i do on my laptop has it heating up considerably and the fan going crazy. f3 shows a much higher resolution than it used to for a given window size compared to 1.12
This fix may suit those who desire the native resolution but until finding this 'fix', the performance degradation was really jarring and confusing to me. How many more people (children!) would be playing on 'retina' macs and for no apparent reason having performance and battery life severely reduced??
request : add option to enable old behavior, ie '2x pixel scaling', within minecraft game itself
screenshot from a near-full screen window when version was prior to 1.13. a 1.13+ screenshot has those numbers doubled.

Issue is specific to Mac due to Apple, not Mojang, and it requires an hack to make it the full resolution. So not an issue to Minecraft. If I was a mod, I would close this as invalid.
