It’s easy to create a password protected text file by using the command line text editor ‘vi’. This is infinitely useful for privacy purposes, whether the protected file is for containing login details, various passwords, personal information, a private journal, or just about anything else that you want stored securely in a single password protected text file.

Vi is considered a bit advanced and has a fairly steep learning curve, but it is very powerful. Fortunately, if you’re looking to just encrypt a text document though, vi can be reasonably simple enough and we’ll cover some basic vi/vim commands to get you started with it for this purpose.

All portable Macs in the MacBook Pro and Air lineup have backlit keyboards these days, which not only makes it easier to type in dim lighting, but let’s face it, it also looks really fancy too. Because the backlighting uses very low power LED to illuminate, there isn’t much of any hit to battery life if the brightness is set at a reasonable or low level, so many people choose to have the backlit keyboard showing all the time, even if lighting situation doesn’t call for it to be useful.

But sometimes the backlit keyboard on a Mac laptop doesn’t work at all for seemingly no apparent reason… and even attempting to manually control the backlighting with the keyboard shortcuts suggests the feature isn’t working or is disabled.

There are a few possible reasons for the backlighting to stop working on a MacBook Pro, MacBook, or MacBook Air, with most offering simple resolutions. If you discover that the keyboard backlighting is not working on your MacBook Air or MacBook Pro keyboard, then follow the troubleshooting steps detailed below. More often than not you’ll be able to resolve the situation rather quickly and easily.

Don’t want to see Notifications and alerts on the login screens and locked screens of Mac OS X? Me neither, and because Notifications can be fairly personal items from calendars, reminders, messages, or apps, they aren’t necessarily something you want on the lock screen of a Mac that is visible in public, like at an office or school. Thus, disabling them allows for a bit more privacy.

iOS 7 brought with it a new way to interact with the music app and your music collection, with a gorgeous gesture-based interactive album art cover view.

The general appearance of Mac OS X has remained mostly the same for several major OS X releases now, but earlier versions of the operating system had a brighter whiter look for window frames and panels, with some pin striping thrown in there. If you’re tired of the newer darker modern theme that exists throughout OS X from Snow Leopard to Mavericks, you can re-theme the appearance of things and get a retro white theme complete with restyled window elements. The resulting appearance is flatter and whiter, and other than the retro looking pinstripes, it actually looks a bit like something Jony Ive would do to OS X with inspiration from iOS 7, showing generally brighter colors, less shadowing, and a flatter look overall.

We showed you how easy it is to quickly add tags to Mac files and folders with the simple drag & drop trick, but what if you want to remove a tag from something? That’s equally easy, and we’ll cover two ways to remove a tag or multiple tags from items that currently have them: through a quick right-click action, or through the Finder toolbar.

These two tricks actually work both ways, and you can use them to add new tags as well, but for this specific articles purpose we’ll focus on removing them.

Lost Mode is an outstanding feature of Find My iPhone that allows you to remotely lock an iPhone with a passcode and an on-screen message, rendering the device unusable while in “Lost Mode” until the passcode is entered correctly. Making this feature even better is the ability to choose a contact phone number for the locked device, and calling that number becomes the only actionable item on the lock screen of the iPhone while in Lost Mode. Theoretically, this could mean the difference of having your iPhone returned to you or not, and it’s all very easy to use.

To use Lost Mode – or have the possibility of using it should you need to in the future – you must have a valid Apple ID with iCloud configured, and Find My iPhone turned on in Settings on the iPhone. Devices running iOS 6 and iOS 7 have full support for Lost Mode with remote locking, messages, the number call back, remote wipe, and mapping, while iOS 5 is limited to just locking. Assuming you meet those relatively basic requirements, here is how to use the Lost Mode feature to remotely lock down an iPhone with a screen message, call back phone number, and a passcode.

We’re all incredibly reliant on our internet connections these days, but sometimes those connections aren’t so reliable. Whether it’s due to an ISP failure, a router being down, someone tripping over a cord somewhere, or whatever other occurrence, it can be frustrating to wait for a downed internet connection to come alive again. We’ve all known users who simply hit the “refresh” button on a web browser repeatedly to see when things revive, but there is a better way. Users who are comfortable with the command line can use a better solution, which utilizes the ping tool to detect an active internet connection and the text-to-speech say command to verbally announce when things are live again. Be sure to have the volume turned up on the Mac to use this.

Newer versions of Mac OS brought significant improvements to multi-display support for Mac users who have their computer connected to an external screen or two.

One of the more helpful feature changes with multi-display support is the ability to access the Dock on any of the connected screens to a Mac through the use of a simple onscreen motion gesture trick. Learning this trick allows you to quickly show the Dock on any display connected to a Mac.

File tagging on the Mac is part of Mac OS X, but those who have been using the Labels feature to help manage their files in prior versions of Mac OS X will notice it’s actually quite similar. Basically you ‘tag’ a file, and then it becomes associated with that tag, allowing for easy file sorting, searching, and management. Tagging is easy to use, and what are likely the two simplest ways to tag files are during the file saving process, which we discussed with some other basic Mavericks tips here, and also with the hugely useful drag & drop trick, which we’ll cover next.

Drag & drop tagging may be the single best way to use tags from the Finder, because not only can you tag a single file just by dropping it onto the tag you wish to assign, but it allows for rapid batch tagging of huge groups of files and folders with the same trick.

It seems that an “Unable to Verify Update” error message arrives at random for some users with just about every single iOS software update, perhaps unsurprisingly, the problem has resurfaced for some when trying to download and install the recent 9.3, 7.0.4, and various other iOS updates. The error seems to be exclusive to using OTA (Over-The-Air) updates, and sometimes it reports an improper iOS version as being available, or tell you that an update “failed verification because you are no longer connected to the Internet” – despite having an active entirely functioning wi-fi connection. If you happen to encounter this error when trying to download and install any iOS update, you’ll be able to fix it in a minute or two using one of these tips outlined below.

Many advanced users prefer to use firmware files when updating their iOS devices to the latest version, and every time an iOS update comes out we post direct download links for the latest versions. Every once in a while we get questions from users who wonder how we find those file links, since they’re tucked away on Apple’s download servers, seemingly hidden from the public view. Well, there isn’t any magic to this and it’s easily done through the command line with a simple trick that pulls a full list of IPSW files that are available directly from Apple. At it’s most basic form it lists literally everything, but with some minor changes to the command syntax you can sort for specific iOS versions or for files that match a specific piece of hardware.

The Dock received a visual overhaul in OS X Mavericks which defaults to removing a minor transparency effect. It’s a subtle change that many users won’t even notice, but the difference is that now the content of windows, images, and items moved below/behind the Dock are no longer visible through what looks like a frosty window. With Mavericks, the frosty effect is stronger and there is no transparency at all, so anything behind the Dock becomes invisible.

Some users won’t care about this or even notice the difference, but for those who prefer the old look of a slightly transparent Dock or who use the auto-hiding Dock feature, it can make for a pleasant if not minor change. You should have some comfort with the command line to do this.

Many Mac users running OS X Yosemite and OS X Mavericks have noticed the purge command, which forces memory cache to be emptied as if it a computer was rebooted, throws an error when attempting to run through Terminal in OS X 10.9 or newer. In most cases that error message is “Unable to purge disk buffers: Operation not permitted”. This does not indicate that purge no longer works in Mavericks, it simply requires super user privileges to execute properly in the latest versions of Mac OS X.
