The bugWh
ats wrong is that when looking directly at a sign that has colors it will show no colors unless you go at a sharp angle that is almost looking directly at the side of the sign will you see the colors on the sign. Anyone witha 2.4 GHz Intel Core i5 MacBook Pro has thisissue and it is quite annoying.Bug Description
While viewing a sign with coloured text, you are unable to see the text colour from the front of the sign on macOS / OS X. This effects every Minecraft version to date (with coloured sign text of course), regardless of macOS version, Java version, or graphics driver version. This bug does not effect Minecraft on Windows or Linux.
Bug Example
Simply spawn in a sign with coloured text with one of the following on macOS / OS X and observe the colour of the text while viewing the sign straight-on and from a sharp angle.
*/give @p minecraft:sign 1 0 {BlockEntityTag:{Text1:"
{\"text\":\"Coloured Text\",\"color\":\"blue\"}"}}*
or*/setblock ~ ~ ~ minecraft:standing_sign 0 destroy {Text1:"
{\"text\":\"Coloured Text\",\"color\":\"blue\"}"}*
Bug Cause
This bug is caused by incorrectly defining the surface normal vector while rendering the text on a sign. This causes the surface "face" to be defined as the back of the sign, rather than the front (where the text is visible). The OpenGL implementation on Windows and Linux appears to have a relaxed policy for applying colour to the surface, while the OpenGL implemenation on macOS has a stricter policy for applying the colour. It appears that OpenGL on macOS does not apply the colour if the surface is not "visible", which is why the colour is only applied on sharp angles to the sign, where part of the surface would be visible.
Bug Fix
This bug can easily be fixed by properly defining the surface normal while rendering the text on the sign. This change does not break rendering behaviour on Windows and Linux (tested on Windows 10 and Arch Linux), while fixing the text rendering on macOS (tested on macOS High Sierra and a beta of macOS Mojave).

This change will correctly define the surface normal to be the front of the sign, fixing coloured signs on macOS.
Bug Description
While viewing a sign with coloured text, you are unable to see the text colour from the front of the sign on macOS / OS X. This effects every Minecraft version to date (with coloured sign text of course), regardless of macOS version, Java version, or graphics driver version. This bug does not effect Minecraft on Windows or Linux.
Bug Example
Simply spawn in a sign with coloured text on macOS / OS X and observe the colour of the text while viewing the sign straight-on and from a sharp angle.
Bug Cause
This bug is caused by incorrectly defining the surface normal vector while rendering the text on a sign. This causes the surface "face" to be defined as the back of the sign, rather than the front (where the text is visible). The OpenGL implementation on Windows and Linux appears to have a relaxed policy for applying colour to the surface, while the OpenGL implemenation on macOS has a stricter policy for applying the colour. It appears that OpenGL on macOS does not apply the colour if the surface is not "visible", which is why the colour is only applied on sharp angles to the sign, where part of the surface would be visible.
Bug Fix
This bug can easily be fixed by properly defining the surface normal while rendering the text on the sign. This change does not break rendering behaviour on Windows and Linux (tested on Windows 10 and Arch Linux), while fixing the text rendering on macOS (tested on macOS High Sierra and a beta of macOS Mojave).

Bug Description
While viewing a sign with coloured text, you are unable to see the text colour from the front of the sign on macOS / OS X. This effects every Minecraft version to date (with coloured sign text of course), regardless of macOS version, Java version, or graphics driver version. This bug does not effect Minecraft running on Windows or any version of Linux (that I know of).
Bug Example
Simply spawn in a sign with coloured text on macOS / OS X and observe the colour of the text while viewing the front of the sign straight-on and from a sharp angle.
Bug Cause
This bug is caused by incorrectly defining the surface normal vector of the front of the sign while rendering the text on a sign. This causes the surface "face" to be defined as the back of the sign, rather than the front (where the text is visible). The OpenGL implementation on Windows and Linux appears to have a relaxed policy for applying colour to the surface, while the OpenGL implemenation on macOS has a stricter policy for applying the colour. It appears that OpenGL on macOS does not apply the colour if the surface is not "visible", which is why the colour is only applied on sharp angles to the sign, where part of the surface would be visible.
Bug Fix
This bug can easily be fixed by properly defining the surface normal while rendering the text on the sign. This change does not break rendering behaviour on Windows and Linux (tested on Windows 10 and Arch Linux), while fixing the text rendering on macOS (tested on OS X Mountain Lion, OS X Mavericks, OS X Yosemite, OS X El Capitan, macOS Sierra, macOS High Sierra, and a beta of macOS Mojave).

Notice the sign of the z-coordinate of the normal vector. This change will correctly define the surface normal to be the front of the sign, fixing coloured signs on macOS.
Bug Description
While viewing a sign with coloured text, you are unable to see the text colour from the front of the sign on macOS / OS X. This effects every Minecraft version to date (with coloured sign text of course), regardless of macOS version, Java version, or graphics driver version. This bug does not effect Minecraft running on Windows or any version of Linux (that I know of).
Bug Example
Simply spawn in a sign with coloured text on macOS / OS X and observe the colour of the text while viewing the front of the sign straight-on and from a sharp angle.
Bug Cause
This bug is caused by incorrectly defining the surface normal vector of the front of the sign while rendering the text on a sign. This causes the surface "face" to be defined as the back of the sign, rather than the front (where the text is visible). The OpenGL implementation on Windows and Linux appears to have a relaxed policy for applying colour to the surface, while the OpenGL implemenation on macOS has a stricter policy for applying the colour. It appears that OpenGL on macOS does not apply the colour if the surface is not "visible", which is why the colour is only applied on sharp angles to the sign, where part of the surface would be visible.
Bug Fix
This bug can easily be fixed by properly defining the surface normal while rendering the text on the sign. This change does not break rendering behaviour on Windows and Linux (tested on Windows 10 and Arch Linux), while fixing the text rendering on macOS (tested on OS X Mountain Lion, OS X Mavericks, OS X Yosemite, OS X El Capitan, macOS Sierra, macOS High Sierra, and a beta of macOS Mojave).

Notice the sign of the z-coordinate of the normal vector. This change will correctly define the surface normal to be the front of the sign, fixing coloured signs on macOS.
Bug Description
While viewing a sign with coloured text, you are unable to see the text colour from the front of the sign on macOS / OS X. This effects every Minecraft version to date (with coloured sign text of course), regardless of macOS version, Java version, or graphics driver version. This bug does not effect Minecraft running on Windows or any version of Linux (that I know of).
Bug Example
Simply spawn in a sign with coloured text on macOS / OS X and observe the colour of the text while viewing the front of the sign straight-on and from a sharp angle.
Bug Cause
This bug is caused by incorrectly defining the surface normal vector of the front of the sign while rendering the text on a sign. This causes the surface "face" to be defined as the back of the sign, rather than the front (where the text is visible). The OpenGL implementation on Windows and Linux appears to have a relaxed policy for applying colour to the surface, while the OpenGL implemenation on macOS has a stricter policy for applying the colour. It appears that OpenGL on macOS does not apply the colour if the surface is not "visible", which is why the colour is only applied on sharp angles to the sign, where part of the surface would be visible.
Bug Fix
This bug can easily be fixed by properly defining the surface normal while rendering the text on the sign. This change does not break rendering behaviour on Windows and Linux (tested on Windows 10 and Arch Linux), while fixing the text rendering on macOS (tested on OS X Mountain Lion, OS X Mavericks, OS X Yosemite, OS X El Capitan, macOS Sierra, macOS High Sierra, and a beta of macOS Mojave).

Notice the sign of the z-coordinate of the normal vector. This change will correctly define the surface normal to be the front of the sign, fixing coloured signs on macOS.
Bug Description
While viewing a sign with coloured text, you are unable to see the text colour from the front of the sign on macOS / OS X. This effects every Minecraft version to date (with coloured sign text of course), regardless of macOS version, Java version, or graphics driver version. This bug does not effect Minecraft running on Windows or any version of Linux (that I know of).
Bug Example
Simply spawn in a sign with coloured text on macOS / OS X and observe the colour of the text while viewing the front of the sign straight-on and from a sharp angle.
Bug Cause
This bug is caused by incorrectly defining the surface normal vector of the front of the sign while rendering the text on a sign. This causes the surface "face" to be defined as the back of the sign, rather than the front (where the text is visible). The OpenGL implementation on Windows and Linux appears to have a relaxed policy for applying colour to the surface, while the OpenGL implemenation on macOS has a stricter policy for applying the colour. It appears that OpenGL on macOS does not apply the colour if the surface is not "visible", which is why the colour is only applied on sharp angles to the sign, where part of the surface would be visible.
Bug Fix
This bug can easily be fixed by properly defining the surface normal while rendering the text on the sign. This change does not break rendering behaviour on Windows and Linux (tested on Windows 10 and Arch Linux), while fixing the text rendering on macOS (tested on OS X Mountain Lion, OS X Mavericks, OS X Yosemite, OS X El Capitan, macOS Sierra, macOS High Sierra, and a beta of macOS Mojave).

Notice the sign of the z-coordinate of the normal vector. This change will correctly define the surface normal to be the front of the sign, fixing coloured signs on macOS.
Bug Description
While viewing a sign with coloured text, you are unable to see the text colour from the front of the sign on macOS / OS X. This effects every Minecraft version to date (with coloured sign text of course), regardless of macOS version, Java version, or graphics driver version. This bug seems to only effect older mac processors. This bug does not effect Minecraft running on Windows or any version of Linux (that I know of).
Bug Example
Simply spawn in a sign with coloured text on macOS / OS X and observe the colour of the text while viewing the front of the sign straight-on and from a sharp angle.
Bug Cause
This bug is caused by incorrectly defining the surface normal vector of the front of the sign while rendering the text on a sign. This causes the surface "face" to be defined as the back of the sign, rather than the front (where the text is visible). The OpenGL implementation on Windows and Linux appears to have a relaxed policy for applying colour to the surface, while the OpenGL implemenation on macOS has a stricter policy for applying the colour. It appears that OpenGL on macOS does not apply the colour if the surface is not "visible", which is why the colour is only applied on sharp angles to the sign, where part of the surface would be visible.
Bug Fix
This bug can easily be fixed by properly defining the surface normal while rendering the text on the sign. This change does not break rendering behaviour on Windows and Linux (tested on Windows 10 and Arch Linux), while fixing the text rendering on macOS (tested on OS X Mountain Lion, OS X Mavericks, OS X Yosemite, OS X El Capitan, macOS Sierra, macOS High Sierra, and a beta of macOS Mojave).

Jordin Smith since it's a non "real" version we can't select it anyway
I can confirm that this happens, it happens on every type of superflat (original, custom).
It is not a change to spectator mode. Spectator mode is affected because you can be in blocks, which, causes the rendering algorithm to find no block faces to render. I will provide screenshots though.

MC-63026Fixed in 14w31a
Happens to me running Java 8 on OS X 10.11 El Capitan. I have found a way to fix it, below is a method of fixing it using MCP mappings:
Go to TileEntitySignRenderer.java
Look for the method: renderTileEntityAt(TileEntitySign, double, double, double, float, int)
Find float f3 = 0.015625F * f;
The third line after that uses this float: GL11.glNormal3f(0.0F, 0.0F, -1.0F * f3); (Probably using GlStateManager but MCP changed it)
Changing this line to not use a negative number fixes it, example:
GL11.glNormal3f(0.0F, 0.0F, 1.0F * f3);
or, more simply:
GL11.glNormal3f(0.0F, 0.0F, f3);
(this is right after you bind the sign texture, right before you disable depth mask)
Using 1.9-pre2 obfuscated:
Go to bps.class
Look for the method: public void a(aqm, double, double, double, float, int)
Find: float \u2603 = 0.015625F * \u2603;
The third line after that uses this float: bnh.a(0.0F, 0.0F, -1.0F * \u2603);
Changing this line to not use a negative number fixes it, example:
bnh.a(0.0F, 0.0F, \u2603);
(this is right after you bind the sign texture, right before you disable depth mask)
Yes this is still in 1.9-pre2, and in 1.9-pre3, I added some screenshots showing it (using Attach Files). Later today I can provide the way to fix it in 1.9-pre3.
Still an issue in 1.9-pre4.
This is still an issue on full release 1.9.
This is still an issue in 1.9.1 and 1.9.2. I'm not sure if it counts but this issue seems to be fixed in 1.RV-Pre1 The Trendy Update (the 2016 April Fools joke). I believe we should wait until the next actual version comes out before marking this as resolved.
This is still an issue in 1.9.3-pre1 and 16w15b.
This is still not fixed on the 1.10 snapshot 16w20a.
This is also in 16w21a.
This is still an issue in 16w21b.
Also, do you mods get a notification if I edit a previous comment? I hate spamming this every update. If not, is it ok if I remove the old messages (every one except the latest)?
Did you accidentally enable touchscreen mode?
Yes that is the problem. If you are not using a touchscreen you should turn it off. The touchscreen mode assumes you will be pressing down for more than just an instant like a mouse click. This is not a bug.
This is still an issue on 1.12.2 and 1.13-pre2 on a Macbook Pro.
This is still an issue on 1.13-pre6. I also updated the bug report with more details.
This is still an issue on 1.13-pre7.
This issue is still present in 1.13-pre8.
This is still an issue for macOS on 1.13-pre9.
Sorry, I was only leaving a comment because FVbico told me to, I'll stop leaving them now
This bug appears to have been fixed in 19w39a. I tested it on my old macbook and the sign rendering was broken in 19w38b but worked fine in 19w39a and 19w40a. Looking at the source, it looks like they removed the offending normal3f() in 19w39a.
Although, with all the changes to the rendering and new issues with signs, I wouldn't be surprised if they reverted this change back, reintroducing the bug. But for now, it appears to be fixed.
I tried to test it yesterday but I was still running an older snapshot for some reason. I attempted to remove those versions when I realized but I guess it didn't work. The only version I am able to change is 1.14.4 (where the bug still occurs), all the others versions are archived and I cannot change them.
I was not able to reproduce this bug in 19w39a or 19w40a.
