auvaltool

You might have to re-install OS X, if you are not able to extract it from the packages. How did you accidentally delete a system file?

now to put the auvaltool back in its place follow this first, this is to find the hidden folder:

Hello Ollie, this line was a little confusing.

"now once done you will want to go onto the finder to macintosh hd and find the usr click it then click bin open the zip and drag it in it worked for me and it should you too !"

Where exactly am I dragging this file into? I'm running Yosemite 10.10.2, Logic Pro and X

Note:

The version of auvaltool provided with an earlier OS X version, may not be compatible with the version included with Yosemite because of changes made in Yosemite and in fact could cause all kinds of issues if used with Yosemite... that could easily be hard to track down and in trying to troubleshoot those, you could end up wasting more time than it would take to do things properly in the first place.

I would recommend, to prevent such possible issues... you simply start again from scratch and install a fresh copy of Yosemite and LP... and not try the method suggested above....

Also, for what it is worth.... supplying a copy of an OS X file to another person via a link to a remote storage system....is actually illegal.... and is against the OS X/Apple's T&C/Agreement/License....
