I am a mac user. I am trying to run Alpha a1.2.6 on my launcher, and I get this error on doing so:
Failed to download file, the file contents differ from what was expected.
Filename on disk: jinput-platform-2.0.5-natives-osx.jar
Path: /Users/Chance/Library/Application Support/minecraft/libraries/net/java/jinput/jinput-platform/2.0.5/jinput-platform-2.0.5-natives-osx.jar
I hope you can help!
NVM, all i had to do was reinstall the file and replace it. done.
