Improve your presentation skills: the emergency road-show toolkit

As I’ve traveled around the world giving presentations, I’ve seen Murphy’s Law in action, up close, many times. Much as I might prepare ahead of time, things still go wrong all the time. And every time something does go wrong, I add another item or two to my emergency toolkit, the better to be prepared for next time.

Here are some of the things that have ended up in that toolkit. If you have a big presentation—especially if it’s out of town, where you won’t have access to your usual resources—consider putting together a similar toolkit of your own.

Gadgets and software

First, let’s talk about the gadgets and software in your toolkit.

How to Secure Your Mac

When you first set up your Mac, the only security measure that’s enforced is that you add a password to your user account. The Setup Assistant makes no mention of extra measures you might want to enable, even though several are built into OS X. The features we’re about to look at are defenses against local attacks, rather than protection against online attacks. The measures are particularly important if you work in an open environment, such as a library, an office, or a café, and if your Mac is stolen, because they help to keep your data under lock and key.

One thing that isn’t covered here is FileVault, which encrypts everything on your Mac so it’s unreadable to anyone who doesn’t have your password. It’s what you might call a nuclear option, though, and carries a risk: if you lose both your password and backup recovery key, which lets you reset your password, you’re forever locked out of your files. You can store your recovery key with Apple, but three questions must be answered precisely for access, so this also carries a risk. FileVault is extremely secure, but its seriousness means we don’t recommend it for everyone.

 

1. Turn Off Automatic Login

Automatically logging into a user account on startup is risky. After holding down the power button to turn off the Mac, a restart is all you need to gain access. Automatic login can be disabled under Login Options in the “Users & Groups” preferences pane.

 

2. Obfuscate Login Details

The login window shows account names by default, leaving passwords to be input. Under Login Options, switch to “Name and password” so both details need to be entered. Changing Fast User Switching to show an icon stops names being read from the screen.

 

3. Restrict Your Abilities

Daily, it’s safer to use a Standard account, but an admin is needed for system changes. Create a new admin in the Users & Groups pane, log out, then into the new account. Select your regular account and clear “Allow user to administer…” to reduce its rights.

 

4. Fully Protect

To protect critical settings, log in from an Administrator account, open the Security & Privacy pane, click General, then click the Advanced button and ensure “Require an administrator password to access system-wide preferences” is checked.

 

5. Request Password to Wake

Waking a Mac from sleep gives access to whatever account was left signed in. Under “General” in the Security & Privacy pane, turn on the option that requires a password to wake, and set how soon it’s needed. Longer than the “5 seconds” option is risky.

 

6. Tighten Keychain Security

Your password also protects your Keychain, giving access to its contents to Safari’s AutoFill feature, for example, just by logging in. To require separate consent, open Keychain Access, right-click “login” in the Keychain list and choose “Change Password…”

 

7. Sharing Services

Features in the Sharing pane allow you to log into a Mac remotely or simply copy files. In particular, review the options under Screen Sharing and File Sharing to ensure your Mac and its contents can’t be accessed by just anyone connected to the same network.

 

8. Lock the Keychain

In the same menu, choose “Change Settings…” for options that lock the Keychain upon sleep or after inactivity. In the app’s preferences, you can add a menu bar icon to show Keychain status and to lock it. When locked, system services may prompt you for access. 

 

9. An Unplugged Hole

Without a firmware password, Recovery Mode gives the unfettered ability to reset any account’s password from Terminal. The Keychain password is unaltered by this, so an intruder won’t be able to read website logins, but they will have access to local files. That’s why you should set a firmware password, as detailed in the next step.

 

10. Set a Firmware Password

Restart your Mac and hold Command + R at the chime. Choose Utilities > Firmware Password Utility from the top bar. Set a password and don’t forget it — you’ll need it on rare occasions such as restoring your Mac from Time Machine, and to use other startup key combinations.

Gear We Love: Mountek car mounts make your CD player useful again

There’s a lot of gear out there for your Apple devices, but how do you know which are worth your time and what’s not worth your money? In our Gear We Love column, Macworld’s editors tell you about the products we’re personally using—and loving.

Though texting and driving is dangerous—and in many places illegal—you do want your phone to be accessible and visible for tasks such as in-car navigation. Which means that you need a good car mount. A few months back, I wrote about Kenu’s Airframe, a compact iPhone car mount that’s perfect for tossing in your pocket or bag (say, for use in a rental car). But I mentioned in that article that when I’m in my own car—in other words, when portability isn’t a concern—I have a sturdier mount that I prefer. That mount, from Mountek, is this week’s Gear We Love.

MacBook Pro (Mid 2014) review: Update offers slightly better CPU performance

Easy Mac Hacks: Stop Power Button from Activating Sleep

Every Monday we show you how to do something quick and cool using built-in OS X utilities such as Terminal, Apple’s command line application. These easy hacks can make life better and simpler, and don’t require any knowledge of coding — all you need is a keyboard to type ’em out!

Have you ever accidentally pressed the power button on your MacBook, only to find that you now have to go through the process of awakening your computer? While your Mac will awaken faster than any other computer on the planet, it’s still an annoying process. Fortunately, you can change the behavior of the power button so that it displays a dialog instead of powering down your computer. Continue reading to learn how to do this.


In order to change the power-button behavior, you’ll want to open the Terminal application (located in /Applications/Utilities), then type in the following command, followed by the enter key:

defaults write com.apple.loginwindow PowerButtonSleepsSystem -bool no

When you enter this command, you’ll want to restart your Mac to ensure this new preference is loaded into the system.

Once entered and restarted, whenever you press the power button on your Mac for a second or two, you’ll be prompted to specify whether you want to sleep, restart, shut down, or cancel. No longer will your Mac choose to sleep automatically.

If you decide that you no longer wish to have your Mac do this, then you can easily reverse the command by opening the Terminal and typing in this command:

defaults write com.apple.loginwindow PowerButtonSleepsSystem -bool yes

When you restart, your Mac will be returned to its normal behavior, automatically putting the system to sleep when the power button has been pressed.

Contexts review: Make your OS X windows more manageable

contexts spotlight

Contexts 1.4 supplements—and can even replace—OS X’s window management tools, and it does so in a way that is legitimately useful, especially if you rely on keyboard shortcuts to navigate your Mac.

On first glance, Contexts has a nearly nonexistent interface: The only sign that it’s running is a narrow window-picker sidebar that runs along the edge of your screen. But its real power lies in its keyboard shortcuts.

Improve your presentation skills: how to make smoother slide transitions in Keynote

Modern presentation apps like Keynote and PowerPoint still encourage you to think in terms of “slides”: discrete, isolated objects to be presented one after the other, as though we were still using those old slide projectors to show film-in-square-frames slides. Our audiences may even expect to receive printed or PDF copies of our slides, one tidy image per page.

But that metaphor is a relic of an earlier time. Technology has moved on, and you can create far more interesting and appealing presentations if you move beyond the idea of “slides” and adopt a more fluid, seamless approach.

The best-known tool for presentations-that-are-not-slides is Prezi (4.0 mice), which gives you a huge canvas on which you place individual elements; you then pan, zoom, and rotate the view to highlight specific items. It’s a neat effect, but I prefer to downplay animations and transitions, not to call extra attention to them.

GoodReader 4 review: An excellent universal app for PDF management

iOS apps are, for me, a lot like cable channels: No matter how many I have on my iPad or my iPod touch, I only use a dozen or so on a regular basis. The others I don’t delete because they give me some feeling of comfort, as in, “I may need this one day.”

Keep it Reel: Record, mix, and release a professional recording on your iPad

The iPad has become an incredible tool for musicians who wish to quickly and confidently record and produce live music on their tablet. Recently, I had the opportunity to produce and record a session for Ella Joy Meir, using just my iPad, software, and recording accessories. Last week, I covered when you might want to use an iPad and what you need to get started; now, let’s talk about the actual recording and post-production process.

Recording, editing, and mixing

There are two versions of the Auria app: one that allows you to record up to 24 tracks (Auria LE, $25) and a more powerful version that can record up to 48 audio tracks (Auria, $50). Auria’s touch interface is excellent: I really believe that using your fingers to trim, fade, cut, copy, and paste the audio regions is the easiest way to edit audio; it removes most of the layers (keyboard, mouse, and control surface) that stand between me and the music when I use more traditional computer-based recording systems. In my experience, the touch interface also makes editing a much speedier task. Another big advantage of Auria is that it offers many of the mixing features usually available only on a computer-based platform, including plug-ins (available via in-app purchase).

Ask: Recover Missing OS X Applications

Got an Apple, Mac, or iOS tech question? We have the answer. In this week’s installment of Ask, we’ll teach you how to recover missing applications that are built into OS X, including utilities. 

Question: I believe that I have accidentally deleted some of the default applications that came with OS X, and I’m not sure how to reinstall them. I’m missing my entire Utilities folder under Applications. How can I get these applications back onto my computer system?

Answer: The default applications bundled onto your system usually requires messing around with the Terminal to remove them, and even then, they can be difficult to remove. If they’ve been removed, however, you can get them back by simply reinstalling your version of Mac OS X. 

If you are running OS X Lion or later, then you can start up your computer while holding down the Option key, and select “Recovery HD.” Selecting this option will boot your computer into the Recovery partition. From here, select “Reinstall OS X,” then follow the instructions to reinstall. 

When reinstalling OS X, none of your content should be be overwritten, but it’s best to always create a backup beforehand just to be safe. Once reinstalled, the default applications, including the Utilities folder, should reappear on your Mac.


Reinstalling OS X is the only way to get back the default applications once they have been removed from your system.

Message to IT from Mac users: Tread lightly

Reader Anthony Lanier wishes to have a cordial conversation with his IT department. He writes:

The division I work in uses Macs but we’ve recently been told that our computers and devices will soon be run by the company IT department, which is very Microsoft and Windows-centric. They’ve solicited our feedback before proceeding but I honestly don’t know what to suggest. Any ideas?

Before I embark on what may appear to be attacks on IT, let me say from the outset that working in IT is a thankless job. They hear from the people they’re trying to help only when those people have a problem, and much of the time they’re approached in anger. So first, be sympathetic to their work and next, be grateful that they care enough to ask for feedback. I’d suggest something along these lines.

Light Up review: Put a spotlight on your photos and slide presentations

As the saying goes, a picture is worth a thousand words—and that’s why creative professionals of all stripes like to communicate their ideas in the form of an image. As it turns out, however, a thousand words can be a few too many when you’re trying to draw attention to a small detail.

Light Up 1.0.3 solves this problem by allowing you to load up an image from a file and blocking it out with a mask whose darkness you can customize to your heart’s content. You can then selectively “carve” sections out of the mask, allowing specific portions of the underlying image to be highlighted. The carving tool supports three different shapes: rectangles, rounded rects, and ovals; you can have as many as you like in your image, and are free to resize and move them around.

How to troubleshoot Mac Wi-Fi problems

For most of us, Wi-Fi has become our preferred way to connect our Macs to other networked devices and the Internet. However, most of us also have times when those connections slow down or fail altogether. When that happens, however, there are several things you can do to diagnose and (ideally) fix the problem.

Signal and noise

The thing to remember about Wi-Fi is that it’s a form of radio: Signals are passed to and from your Mac and your router (and any other networked devices) by transmitters and receivers at both ends tuned to the same frequency. While the information being sent might be digital in nature, the medium it rides on is analog. As such, the ability to transmit and receive data via Wi-Fi is dependent on two things: the strength of the signal between those transmitters and receivers; and the volume of interference—unusable “noise”—from other devices using that same frequency.

Illustrator CC2014 review: Adobe continues to add refinements that benefit illustrators

Adobe continues to refine its flagship illustration tool with Illustrator CC 2014, a minor update with just a handful of feature additions. Interestingly, many more new features were introduced to the vector app with the mid-cycle Illustrator CC 17.1 update in January. A number of these earlier additions merit discussion, and combined with the enhancements in CC 2014, they address one of the longest-standing complaints I’ve had with the application.

Better tools

In my past Illustrator reviews, I have consistently lamented the application’s anemic object tools. Select the rounded rectangle tool, click the artboard and you’d be asked to specify the corner radius; once the radius was determined, it was locked in and uneditable. Stretch the object in one direction, and the corners would stretch and distort, too. Similarly, the star and polygon tools provided little in the way of settings, and those too were locked in once set. Creating a star with rounded corners or a polygon in the shape of gear was a logistical nightmare for even the most hardened Illustrator veterans.

Keep it Reel: Make your iPad into a professional recording studio

Since the introduction of the iPad in 2010, I have dreamed of the day when I could walk into a studio and record, produce, and mix a live band using just my tablet. Recently, that dream became reality: I had the opportunity to produce and record a session for Ella Joy Meir—a very talented up-and-coming songwriter and composer based in the Boston/New York area. The plan was to record “You’ll Return,” an original song that she co-wrote with Michal Weiner, using a band made up of drums, acoustic and electric guitars, bass, vocals and piano.

For this project, I decided to try and use the iPad for each stage of production—from recording and mixing all the way to mastering and SoundCloud distribution. The recording session was split in two days and took place in the new Berklee Production suites in Boston; the assistant engineer was the talented Vince Espi. (I’ve posted videos of the sessions and some of the things that went on behind the scenes.)
