99 ways to make your computer faster. i tried typing something into terminal and i think that where i screwed up my computer. i typed "com.apple.frameworks.diskimages skip-verify TRUE" and hit return.i tried typing it a few fifferent ways like "com.apple.frameworks" and "com.apple.frameworks.diskimages". i think ever since i did that my computer is not letting me open certain applications. java seems to be screwed up. when i try to open java it switches to terminal and this is what it says.

The command you mentioned would ahve skipped verification of disk images, which could lead to a damaged or corrupted image crashing the disk image utility.

Open Disk Utility, click your hard disk, and then Repair Permissions. If that doesn't help, restart.

i tried both of those things and it still isnt working. whats also weird is terminal isnt letting me type anything in it anymore?

Try running:

java -version

If that outputs the version, then it's okay. Since you didn't give java any arguments, it throws out the help.
