Good heavens there are a lot of warnings in modern computing operating systems, am I right? Yes, I totally did want to close that window. Honest.
One of the more annoying warnings in OS X is the one that pops up when you try to change the three letter extension on a file, like changing an image file to something else, say, .jpg to .gif or whatnot. Honestly, I should be able to do this. Usually, I do it when I get a file from another person who may not have such a great handle on how the file extensions work. If you want to get rid of the standard warning when you do this, today’s tip should help.
