Typing “File:///” will crash your Mac
An interesting bug was recently discovered for Mac computers whereby if you type "File:///" without the quotation marks in your Mac running the latest OS X Mountain Lion, it will crash whatever application it's written on.
"A closer look shows the bug is inside Data Detectors, a feature that lets apps recognize dates, locations, and contact data, making it easy for you to save this information in your address book and calendar," says Slashdot.
Sure enough we tried this in our office iMac running Mountain Lion and typing these eight characters in Spotlight, Chrome, Safari and Mail crashed each of these applications. So far the problem only appears to be on Mountain Lion and doesn't seem to affect OS X Snow Leopard or iOS devices. A small and (so far) harmless bug that will surely be fixed soon, but it goes to show that every company is susceptible to lazy programming.
