Every Monday, we'll show you how to do something new and simple with Apple's built-in command line application. You don't need any fancy software, or a knowledge of coding to do any of these. All you need is a keyboard to type 'em out!
There are many reasons you might want to see what application is currently writing to the disk drive on your Mac. Particularly if you've got an app that's running a little slow, and you want to know why. Writing to the disk is still one of the slowest processes your Mac can perform, and when an app is eating up time writing files to the disk, it can make your entire system feel sluggish. With the fs_usage Terminal command, you can see exactly which process is writing to your drive frequently.
AppleCare technicians may soon be able to do initial troubleshooting of your troubled iPhone remotely. The new system, reportedly announced internally at Apple, would apparently be able to collect various bits of diagnostic information from your iPhone and send it directly to Apple servers for immediate analysis.
This new, web-based version of the same diagnostic tools AppleCare technicians already use, would allow a technician to send an email with a unique URL to your iPhone; when you click the URL, a lot of data will go back and forth that may save you a trip to the Apple Store.
