My Minecraft keeps showing error messages when I start the launcher. I tried placing the launcherpack.izma file in manually, but when I try to login, it says something about the "trustAnchors parameter must be non-empty".
I tried everything from uninstalling Java and then reinstalling it to doing the same with Minecraft. I'm not 100% sure if it is just Minecraft or it is my OS. I just installed OS X Mavericks (10.9) and Minecraft hasn't been working since then. This is the error message:

Please fix the error and restart.

I'm having that problem too. Both the vanilla launcher and magic launcher aren't logging in. I think the following might be the cause, as I upgraded yesterday as well:

System.getProperty('os.name') == 'Mac OS X'
System.getProperty('os.version') == '10.9'

Edit: Found the problem. I uninstalled Java 7 (including the JDK) and reverted to Apple's version of Java 6. Minecraft runs fine now.

I also installed Java 6 as well. I have no clue why this would happen with Minecraft. I assume that Java just could't work well with these types of applications. I analyzed what was happening and figured out that the launcher was being sandboxed by Java and couldn't accept any incoming or send outgoing connections. Very strange....

Installing this resolved this issue for me:

Yeah, I ended up completely uninstalling Java 6 and 7, then reinstalling 6. After that worked, I installed the Java 7 JRE and JDK. Now it works fine.
