Mac OS X: While most users don't have to deal with it, some of the hacks we feature here require permissions editing. Free app PropEdit takes out the pain by letting you edit all your permissions from one simple window.
Whether you've built a Hackintosh, migrated to a new Mac, or you're just trying to share some data with another operating system, you'll probably have to deal with your file permissions, and it isn't always fun. Sure, you could always hit "Get Info" on a file or folder, or open up a Terminal and chmod your way through your files, but that doesn't give you an easy overview of how your permissions stand across your files and folders. PropEdit makes it much easier by providing you a Finder-like window that lists, at all times, the permissions of the file or folder you've selected.
From the main window, you can click on any file or folder and change its owner, its read and write permissions, and even turn it into a hidden folder with a simple checkbox. Now, if you ever have problems with a file or folder denying you access, you can just pop open PropEdit and see what's what—no Terminal-fu required. It's not something that every user will necessarily need, but if you've run into this problem before, you know how helpful a program like this can be. Hit the link to check it out.
PropEdit is a free download for Mac OS X.
