10 fun and useful Terminal commands for OS X

By Anthony Bouchard on Feb 28, 2016

Terminal is a powerful tool that comes with OS X. It allows you to input commands and get output from your operating system.

Although Terminal, which is a command line interface (CLI), is powerful and often times even more powerful than a graphical user interface (GUI), it’s often under-used because either people don’t take the time to learn commands, or they are too afraid to dabble in commands because one typo and you could mess something in your system up.

Fortunately, not all commands are scary. In this piece, we’ll show you ten commands you can perform with Terminal that could be of use to you now, or in the future. Read More

 

How to fix Ethernet problems after a recent Mac security update

By Anthony Bouchard on Feb 27, 2016

As my colleague Christian reported on Saturday, some Mac models have been plagued by non-working Ethernet ports after installing a new security update outed by Apple. Although a lot of modern Macs don’t even have an Ethernet port, many models still carry it and many people still love using a wired internet connection because it’s faster, more reliable, and more secure than a wireless network.

The security update, known as “031-51913 Incompatible Kernel Extension Configuration Data 3.28.1,” reportedly blacklists the Broadcom BCM5701 driver used by the Ethernet port that comes standard on many Mac machines.

Fortunately, there’s a light at the end of the tunnel for anyone experiencing issues with their Ethernet ports after installing this security update. Apple has issued a support document on Sunday that notes how to fix the problem. In this tutorial, we’ll go over the steps to fix the problem yourself.

How to change how frequently your Mac checks for software updates

By Anthony Bouchard on Feb 23, 2016

Apple used to let you configure the frequency at which your Mac would check for updates via the System Preferences app, but recent OS X releases have done away with that. Instead, your Mac automatically looks for software updates, whether they’re for OS X or your Mac App Store apps, on a weekly basis.

If you’re interested in changing how often your Mac checks for software updates, you’ve come to the right place. In this tutorial, we’ll be showing you how to change the frequency that your Mac looks for software updates and notifies you of them so you can more easily stay up to date with the latest bug fixes, security improvements, and new features among other things.

Two ways to quickly keep your Mac from sleeping, dimming, or showing a screensaver

By Anthony Bouchard on Feb 17, 2016

When you’re away from your Mac for extended periods of time, depending on the settings you’ve set, it’s going to do one of four things: 1) fall asleep, 2) dim the display, 3) show a screensaver, or 4) do nothing at all.

If you like it when your Mac falls asleep when it’s convenient, and not when it’s not convenient, then chances are you don’t have your Mac set to never fall asleep, but rather you live with annoyingly having to tap a key or touch the track pad to wake it up when it idles for too long.

In this tutorial, we’ll show you two easy ways to temporarily keep your Mac from falling asleep, dimming the display, or showing a screensaver for as long as you it need to. Read More

How to change the default name of screenshots on Mac

By Sébastien Page on Apr 16, 2015

When you take a screenshot on your Mac, OS X will by default name the file “Screen Shot Date Time” where “Date” and “Time” are the actual date and time when the screenshot was taken. This makes for long file names that aren’t necessarily helpful. If like me you want to have more control over that file name, then read on as I show you how to change the default name of screenshots on Mac. Read More

 

How to quickly toggle dark mode using a keyboard shortcut on Mac

By Jeff Benjamin on Feb 27, 2015

Dark mode is one of the more popular features of OS X Yosemite, because it allows you to add a dark tint to both the dock and the menu bar on Mac. The standard way to enable dark mode involves venturing to System Preferences, opening the General section, and clicking on the enable dark mode option. But wouldn’t it be cool if you could toggle dark mode using a simple keyboard shortcut?

MTerminal is a great replacement for Mobile Terminal

By Jeff Benjamin on Feb 16, 2015

Since the realization that jailbroken devices can be permanently bricked, it’s a good opportunity to remind you to change your iPhone’s root password. Using a terminal emulator makes changing the password a piece of cake. Unfortunately, the most popular terminal emulator hasn’t been updated for iOS 8 or for newer devices like the iPhone 6.

Thankfully, there is a free alternative terminal emulator available in Cydia, and it’s actually a fork of Mobile Terminal. Entitled MTerminal, this lightweight Mobile Terminal alternative comes from developer lordscotland, and features iOS 8 support with optimization for big screen devices. Read More

 

How to enable key repeats on your Mac

By Timothy Reavis on Jan 14, 2015

One thing I’ve always liked about Macs is their secondary keys, where holding down a letter key will display variations of that letter, like holding down “u” to get “ü.” This comes in handy when spelling non-English words, but if that’s not something you ever do, Apple’s substitution of special characters for the traditional key repeats of Windows computers can be an unneeded – and perhaps unwanted – feature.

The good news is that there’s a simple way to take control and change the behavior of long key presses to accommodate your needs. This not only works with letters, but number keys as well. Read More

 

How to enable text selection in OS X’s Quick Look

By Timothy Reavis on Jan 7, 2015

Anyone who has used a Mac for more than a minuscule amount of time has more than likely come across Quick Look, the pop-up window that is invoked with a press of the space bar when a file or folder is highlighted on the desktop or in Finder. Quick Look’s usefulness becomes evident when file names aren’t descriptive enough by allowing users to view the contents of many different types of files without having to open them in a full-fledged application like Pages for documents or Preview for images.

By default Quick Look can only display a static view of a file that only grants users a peek at the contents without any real function. Imagine, however, being able to copy a document’s text without having to open it in TextEdit or Pages. This is incredibly useful in a variety of situations, from dealing with templates to Word documents to code snippets, where having multiple applications and documents opened shouldn’t be necessary for copying from one location and pasting to another. The good news is that this functionality is completely possible and perfectly easy to enable. Read More

 

Apple readying a fix for Bash vulnerability, ‘vast majority’ of Mac users unaffected

By Christian Zibreg on Sep 26, 2014

A fix for a new kind of exploit recently discovered in the Bash command shell used in multiple versions of Unix is underway, Apple confirmed Friday, adding that the “vast majority” of Mac users are unaffected because OS X is “safe by default” from the so-called ‘Shell Shock’ attacks.

“The vast majority of OS X users are not at risk to recently reported Bash vulnerabilities,” an Apple spokesperson said in a statement quoted by The Verge.

The vulnerability was documented and publicized Thursday by security researchers at RedHat and gained prominences after security expert Robert Graham called it “as big as the Heartbleed bug,” referring to a nasty vulnerability discovered earlier in the year in the OpenSSL software commonly used by nearly two-thirds of servers powering the Internet.

New Unix command line exploit makes Macs vulnerable to attacks

By Christian Zibreg on Sep 25, 2014

A new exploit in the Bash command shell found in many versions of Unix, including Apple’s OS X desktop operating system, makes Mac computers vulnerable to so-called ‘Shell Shock’ attacks, security researchers at RedHat discovered Thursday.

Though the exploit lets attackers run malicious scripts remotely, most people are not at risk unless they’ve manually allowed SSH access from remote connections or a web server running server side scripting.

Here’s how you can check if you’re vulnerable and what you can do in order to avoid ‘Shell Shock’ attacks on your system. Read More

 

How to show hidden files and folders on Mac

By Sébastien Page on Aug 4, 2014

Some people like to know everything that is on their computer. Admittedly, I was one of these people many moons ago, when I was a Windows user. I would always make sure that Windows Explorer would show all hidden files and folders. I’m not sure why, but I liked it this way.

These days, I’m quite the opposite, as I like to see as little files and folders as possible on my Mac. But I understand some people out there have the desire to see all those files and folders, for whatever reason that may be.

In this post I will show you how to show hidden files and folders in Finder on your MacRead More

 

How to run a terminal session via Notification Center

By Jeff Benjamin on Jul 23, 2013

It’s neat to see the terminal get lots of love from the jailbreak community this week. We just got the new MobileTerm Backgrounder tweak, and now we have another new tweak related to the terminal — NCTerminal. As you have probably figured out by now, NCTerminal allows you to run a terminal session directly in Notification Center. That being said, I will say that the tweak is a bit on the peculiar side, as you’ll see in my full video walkthrough. Read More
