The Finder has been with the Mac since day one, way back in 1984. But just because it’s old, doesn’t mean that it doesn’t have some new tricks. Did you know, for instance, that you can add a path bar to the bottom of the window to show the path of the current folder on your Mac? Or that you can add a status bar in the same spot so you always know how full your drive is? Or that you can add a permanent preview pane over on the right side of a Finder window, even in icon and list views?

Let’s take a look, and see what else you can do.

We all know about forwarding email. It’s the electronic equivalent of putting a received letter in a new envelope and sending it on to someone else. But did you know that you can also redirect emails so that it seems like they arrived from the original sender? You could, for instance:

• Redirect instructions from your boss to a co-worker.
• Pass an email to someone else without getting caught in an inevitable and endless Reply All mess.
• Send a customer enquiry to the correct person, with their reply going direct to the customer.

Unless the final recipient is really brain-dead, then this will never work as a scam to trick them into doing all the work your boss assigned to you, but it’s a very practical alternative to just forwarding emails.

When you want to get back to a previously viewed page in Safari on your iPhone, what do you do? Do you keep tapping the back button until you find the page you want?

If so, you can forget that nonsense right now, because there’s a super-quick way to see a list of all the web pages you’ve recently viewed in a Safari browser tab.

Quick Look is one of the Finder’s best features. Whenever you have a file selected in the Finder, just hit the space bar and you’ll see a preview of that file. It’s a great way to quickly view photos, or read the contents of a document, without opening it in an app.

But did you know you can pull up full-screen Quick Look slideshows just as easily?

One great recent addition to GarageBand for iOS is the Visual EQ, an equalizer that is about as far away from the 1980s-style bank of sliders as it’s possible to get. The Visual EQ also shows you a waveform of the actual sound you’re adjusting, so you can see as well as hear the effects immediately. This visual element, combined with a clever three-“band” EQ, makes this a very powerful tool for shaping your music.

Try this: If you’re reading on a Mac, go ahead and pinch in on your trackpad with all five fingers. If it’s enabled, then you’ll see a grid of apps. lots of apps. That’s Launchpad, which is kind of like an iOS home screen for your Mac.

The problem is, it shows all your apps, in seemingly random order. There’s a search bar to narrow things down, but by the time you’ve got that far, you may as well have used Spotlight to launch your app. Happily, the Launchpad is quite customizable. You can make iOS-style folders, and organize the apps into any order you like. Here’s how.

Spectre is the worst kind of security flaw. Not only do the partial fixes not even protect against attacks, but they also slow down your iPhone, or other device. But things aren’t quite as bad as they seem. You can take steps to speed up your iPhone once again, and one of the fixes not only makes the web faster, but also fixes Spectre’s biggest attack vector.

Did you know that leaving your MacBook plugged in all the time is a sure way to ruin its battery? That instead you should use your notebook computer on battery power for an hour or two each day? That’s the advice from battery health app FruitJuice, which will help you to keep your battery in tip-top condition.

Your Mac has a built-in dictionary and spell-checker. You knew that. You also know that you can add and remove words from that dictionary as you go, teaching the dictionary on the fly.

But did you know that there’s also a text document on your Mac that contains your entire personal custom spelling dictionary? And that you can use this to move your spelling preferences between computers?

You can!
