If your iPhone has LTE networking, and most do these days, there are some situations where you may want to disable the LTE cellular network. This can be helpful in a variety of cases, from a self-imposed data throttle of sorts, to even gaining a more stable connection in a situation where you may notice the LTE network will drop or cycle quickly between 3G, LTE, or even 2G / EDGE. That latter situation, which usually occurs in low coverage areas, can lead to quick battery loss or continuously dropped calls, as the iPhone is constantly seeking a signal, and turning off LTE is often a quick remedy for it.

Did you know your Mac has built in DTMF tones? It sure does! It’s likely part of the ability to make phone calls from a Mac via the iPhone, but putting aside the obvious utility of the tones existence, it’s also kind of a fun retro throwback to the caveman days of using dial tones to make calls.

Have you ever noticed that most politicians speak in remarkably simplified plain language? This is intentional, with most communicating far below their educational achievements and speaking somewhere around a fourth grade level, and sometimes a bit higher. The idea is to make concepts simple, with the message easy to understand, easy to remember, and easy to digest. While politicians may do this to improve comprehension or even pander, it’s actually harder to write (and speak) with a simplified vocabulary than you may think. That’s where this fun little free Mac app comes in, it aids in that simplification process, and it’s actually pretty useful for anyone looking to improve their communication!

While most Mac users have been able to update to OS X 10.11.4 without an issue, some users are experiencing a few particularly frustrating issues with the update. The most common issues are; Mac apps are unable to launch and the apps report they are damaged, Mac application icons show as generic and are unable to open or fail to open, the Mac suddenly freezes for no apparent reason, or a particularly alarming scenario where all applications and user files are missing from view, making it appear as if the Mac removed all of its own files.

An array of problems have appeared for some users updating various iPhone, iPad, or iPod touch models to iOS 9.3, so much so that Apple has actually pulled the iOS 9.3 update for most older model hardware. This means that many devices will simply have to wait for a newer fixed version if they haven’t updated to iOS 9.3 yet, but obviously that’s not too helpful if you already updated a device to iOS 9.3 and it is now rendered inoperable with an activation error, verification problems, iCloud issues, Mail and Safari link failures where a link is clicked but does not open, or some of the other annoyances that have popped up with the software update.
