As with many other Unix-like systems that have a BSD interface, OS X includes a fully Unix-compliant terminal that can be accessed with a Unix shell in the included Terminal utility. This feature allows for a relatively powerful way to access and modify system settings to customize and troubleshoot the system.

As with the rest of the system, this command-line interface is by default limited by standard permissions restrictions so only administrators may access system files and only users may access their own files. To get around this, the sudo command is commonly invoked to execute commands as another user, … Read more

For some paid apps there are also trial or free counterparts. On a lot of these trial apps, you'll find that the only difference is that they are ad-supported. Upgrading may remove the ads and nothing else, so you may not even need the paid version. However, many paid versions of apps offer the best features -- you know, their selling point.

Let's say you bought an app that you can't gauge its usefulness in 15 minutes or less. Or maybe the app is freezing your device when you use it and figuring out what's going … Read more

Like most humans, you probably forget to ask certain questions or make certain plans when you're on a call with someone. It's that moment when you hang up, only to remember exactly what you were supposed to talk about. How annoying. Instead of trying to remember everything in your busy life, or having to call people back all the time, why not let your Android remind you of what you need to say?

Naturally, there's an app that does this -- though seeing it integrated into the stock Android system would be a nice future perk. bytNotes, … Read more

Modifier keys for Mac systems are the Shift, Control, Option (Alt), Command, and Caps Lock keys. The commands triggered by combinations of these keys can greatly speed up how you use your computer, but it can slow you down again if you switch to a keyboard with an unfamiliar layout.

While most Mac keyboards have these keys in the same relative locations, so you don't have to change your typing habits, there are situations in which you may end up using something different, such as if you take a laptop to the office and plug in whatever keyboard you … Read more

There are times when using the Terminal that you might enter a command or two and then want to either run it again or review a whole sequence of commands that have been entered. This can easily be done by pressing the up arrow, scrolling through the previous commands, and then pressing Enter to execute the selected one again. In addition to this approach, the Terminal supports a number of other options for revealing and rerunning entered commands.

The Terminal is able to do this because it stores a small history of the commands you have run both in its … Read more

Apple includes a number of screensavers in OS X that provide you with options to exercise your display and prevent LCD ghosting, CRT burn-in (if you still use a CRT monitor), or other persistent images from being a nuisance. As with most screen savers, you can deactivate them by moving your mouse or pressing a button on your keyboard; however, this may not always be the case, and depending on the screensaver being used you may instead find the screensaver will persist even when some inputs are pressed.

Apple's built-in Calendar application in OS X is a convenient calendaring tool to have; however, its default method of entering calendar dates may be a bit cumbersome by first appearances.

When you first enter an event in Calendar, you select the calendar you wish to use and then double-click the date on which to create the event. You can then title the event accordingly. By default this action creates an all-day event that will further need to be refined by editing it to adjust its time frame. While those who use Calendar may find this somewhat acceptable though a … Read more

To help identify your user account from others who use your system, OS X assigns your account a small picture that appears in various places in the system, including the log-in window as well as in applications like Mail.

When you initially set up your account in OS X, the system will have you set up your account picture, but often people skip by this step and continue with the setup process to start using their computers quicker, leaving their accounts with the image that OS X randomly chooses for it. However, if you would like to change your account … Read more

If you access your computer remotely, then services like Apple's "Back to my Mac" have their conveniences; however, this and similar services are useful for individual machines only. On the other hand, if you have more than one device on your home network that you might wish to directly access, then using a virtual private network is beneficial as it places your system on your home's network so you can communicate with devices as if you were at home.

Often the implementation of this is to use a hardware-based VPN (likely built into your home router) … Read more
