If your Mac is sick, the first step is to restart it. But did you know that there are several tricks you can perform while your Mac is starting up?

Many of these are advanced Mac diagnostic tools, which shouldn’t be used unless you really know what you’re doing. But some not-so-secret startup keyboard combos will remove a stuck disk (if your Mac is old enough to even have a disk inside), let you boot your Mac from a USB drive, or to turn your entire computer into one big storage disk to connect to another computer.

The Home button on your iPhone has multiple purposes — unlocking your iPhone, bringing up the multitasking menu, returning to the home screen, invoking Siri, etc. Such frequent use can take a toll on the Home button’s responsiveness. Although it is designed to last, it can become laggy or less responsive over time. Surprisingly enough, a large number of Home button issues have more to do with the software rather than the actual hardware.

If you notice that your iPhone’s Home button isn’t as responsive as it used to be, here are a few tips you can use to fix the Home button lag.

You’ve all been there. You’re sitting near a window or a lamp, reading an excellent article on your iPad — perhaps a well-written How-To from Cult of Mac — and your iPad’s screen Auto Brightness is going haywire. You slide open Control Center, and set it back where you want it, and continue reading. Then, you turn the iPad a little too far towards the light, and the screen brightness creeps up again.

In iOS 10 and prior, you’d just open the Settings app, tap Display & Brightness, and hit the switch for Auto Brightness. In iOS 11, that option has disappeared. The good news is that it hasn’t gone — the Auto Brightness switch has just moved.

WriteMapper is a new Mac app that combines a mind mapper with a text editor. It works like a regular mind-mapping app, with easy-to-create nodes to get your ideas down and arrange them. But if you open a node, you get a full-featured, cleanly-designed text editor in which to write, so you don’t have to switch to a word-processor or anything else to complete your project.

Then, when you’re done, you can export the mind map as a document to publish it, or whatever you want to do with the finished text.

Picture the scene: You’re on a plane, and your iPhone is your entertainment hub. You may be listening to podcasts, or music, or audiobooks. You may be playing a game, or reading Instapaper, or just checking and editing your vacation photos. Whatever you’re trying to do, it will be interrupted every time you unlock your iPhone, because your stupid boarding pass is right there on the lock screen. Even hours into a transatlantic fight, the boarding pass you already used hangs around, blocking things like the now-playing feature, and lock-screen controls for any music or audio apps.

Thankfully, it’s easy to get rid of — if you know where to look.
