Black screen when playing Minecraft

In theory this is a duplicate of MC-21603 but the difference is that I am on the newest OS X Mavericks, 10.9.4. This started happening after installing prerelease 2.

Aiur:~ riddle$ java -version
java version "1.7.0_45"
Java(TM) SE Runtime Environment (build 1.7.0_45-b18)
Java HotSpot(TM) 64-Bit Server VM (build 24.45-b08, mixed mode)

Doesn’t happen when I play 1.7.10.

Can I respectfully ask why? I have both Java 6 (supplied by Apple through Software Update) and Java 7 installed through Oracle’s JDK installer. Minecraft used to run swimmingly until I installed Pre Release 2 which caused two black outs. I didn’t change Java version, but Minecraft did install new lwjgl version. How is this remotely my fault?

Edit: On top of that, your link is just for OS X 10.5. I run 10.9 and the tutorial you linked is 5 years old.

Minecraft does not automatically use Java 7. You are the first person to report this issue, so it is most likely an issue with your system.
The tutorial also applies to newer versions, it's the official guide given out to people on #minecrafthelp.

I Googled for a way to force Minecraft to use Java 7 and it seems to be stable now.

I still insist that it is a problem with Minecraft 18 pre-2 on OS X because:

1. Even the newest version of OS X (10.9) ships with Java 6
2. Minecraft 1.7.10 and even snapshot 14w34d caused no issues when run under Java 6

Conclusions:

1. Something changed between last snapshot and pre-release, possibly unstable lwjgl seeing as .minecraft/libraries/ has new folders called 2.9.2-nightly-20140822
2. Minecraft 1.8 might be broken for a fraction of Mac user base – they will most likely not know to seek help by downloading Java 7 from Oracle’s servers.

I think it’s imperative to get this information out to developers. They might not know how to fix it immediately but they should be aware of this issue which seems to have resurfaced. You closing the ticket automatically with your first command comment makes this impossible.

The tutorial also applies to newer versions, it's the official guide given out to people on #minecrafthelp.

That turorial is heavily outdated. New OS X versions are only distributed via Mac App Store and Java 6 is updated through the same App Store mechanic, system-wide. My Java 6 is up to date, because it’s a version provided by Apple. If a user wants to install Oracle Java, they can only install Java 7, as Oracle’s Java 6 is no longer supported for OS X. Which brings us back to my original issue with your suggestion: it’s outdated.

That tutorial still works to reinstall Java on Mac, which is required in some rare cases (if the users managed it to corrupt their Java).
If other people are starting to report this, I will reopen this.

Just uninstall ALL Java from your system, then install the latest version.
