Search directory of .psd files for specific text?
I have no idea if this will work because I don't know how PSD files store text, but try this. Open terminal (applications/utilities), type cd &lt;space&gt; and drag the folder containing PSDs onto the terminal; the folder path will be filled in. Hit enter. You are now "in" that folder in your terminal.
Next, do grep -i "some string here" *.
cd tells the system to change directory. grep is a command line utility that opens a file and searches for a string. -i is a flag that tells grep to ignore case sensitivity. Then you give it the string and * means all files in the current directory.
See if that turns anything up.
