The PDF file format is ubiquitous for good reason, mostly because it allows for perfect preservation of a documents formatting, text, and other elements, but also because it allows for encrypted password protection of documents. But let’s face it, sometimes PDF files can be bloated, and something that should be 200k or less can be 1.2MB for no obvious reason, particularly if they have been generated at the OS level from something like printing to a PDF, another file that has been converted to a PDF, or created with an app that just doesn’t offer any compression at all.

This article will show you how to reduce the file size of PDF documents using tools included in Mac OS Preview app, which is bundled by default on every Mac. The shrinking of the PDF file size can be very effective and dramatic, so if you need a notable reduction in PDF file size this guide should be of great assistance to you.

Apple has long included various means of placing parental controls and filtering for content available on the iPhone, iPad, and iPod touch, but up until recent iOS updates there was not a simple method of blocking web-based adult content and material in Safari. That has changed with new iOS releases, which makes it extremely easy to prevent access to adult themed web sites and general content that is deemed inappropriate for youth.

The web restrictions are very easy to toggle on and off and access to them is password restricted, which makes it perfect to quickly turn on before handing an iOS device off to a youngin’ for unsupervised use.

Many urbanites and city dwellers get about by walking, the oldest form of transportation in existence. If you’re one of us who often gets about a concrete jungle by propelling your legs in a forwardly direction, you’ll be pleased to know that the popular mapping applications in iOS have you covered. Both the default Maps app from Apple and Google Maps offer walking directions, though using each is slightly different.

Just about every semi-technical person has setup a wireless router at home or in the office, and in that process has wondered which broadcast channel would be the best to use. Sure, some wi-fi routers make it simple and will recommend a channel on their own, but often it’s left up to the user to decide. Let’s face it, most people have absolutely no idea what would be the best wi-fi channel, let alone which to use for a 5GHz wireless N network versus a 2.4GHz 802.11b/g network, or even what the difference between the networks is. For average people, it’s a bunch of meaningless technical jargon, they just want wireless internet, and they want it to be fast, right? Thankfully, OS X Mavericks makes this simple when a wi-fi router doesn’t, with a simple solution offered through the bundled wi-fi scanner app that works with every single wi-fi router brand out there.

If you’re like me, you carry the full length MacBook Air / Pro MagSafe adapter cord with your portable Mac. And if you do, you’re familiar with how cumbersome having that large extender cable attached to the MagSafe is, either taking up tons of space as it unwinds, or just being a huge tangled mess. But check out this brilliant simple wrapping trick discovered Twitter by @JC.

Rather than wrapping the little power cable first and trying to wrap the large power cable separately, loop the larger cord around the MagSafe adapter and use the smaller power cord to secure the thick one in place! That may sound confusing to explain, which is why it’s best demonstrated with the picture. Give it a try, it secures extremely well and it packs down much smaller than any other solution I’ve found (aside from just leaving the large extender cable out of your bag, of course). Awesome!

It’s easy to wind up with a lot of apps installed on our iPhones and iPads, and if you’ve ever wanted to see every single app on an iOS device you have probably noticed there isn’t any obvious way to do so without connecting to iTunes or looking at the Storage Usage list in Settings.

Well, obvious is the operative word there, because it turns out there is a very simple trick to list all apps installed on any iOS device with the help of Spotlight.

The app list will include both third party apps downloaded from the App Store as well as the Apple defaults that come preinstalled on all iOS devices.

Do you have your terminal windows arranged in a particular way, perhaps running particular processes, that you want to consistently resume to without having to rearrange and relaunch things? Rather than relying entirely on the OS X Resume feature, you should use the Terminal app “Window Groups” tool, which lets you save not only the placement of groups of terminal windows, but also their commands and processes. These can be quickly resumed to at any time, making it simple to manage specific window configurations and workflows for specific command line tasks. This feature has been around in Terminal app on the Mac for quite some time, but it goes largely ignored even by the most advanced command line users. Fortunately, it’s extremely simple to configure and to use, and once you get accustomed to it, you’ll wonder how you ever functioned in Terminal without it.

It’s a fairly widespread complaint that iOS 7 can feel sluggish running on the oldest supported iPad and iPhone hardware, but with a few tweaks you can usually speed it up enough for the performance difference to barely be noticeable, if at all. Those adjustments are limited to the general iOS experience though, and they don’t make much of a difference for in-app performance with even simple tasks like web browsing, which on some hardware can be just strangely slow and choppy. That’s exactly what we’re going to focus on resolving here though; speeding up web browsing with the Safari app on older iOS 7 devices. It works quite well, but you’ll have to turn off Javascript support to gain the speed, which may make this performance tweak not suitable for all users.

Tis the season for some winter fun and holiday magic… in your Mac OS X Terminal with some digital snow fall!

This nifty not-so-little ruby command string will make it snow in the command line of your Mac, there isn’t much to get it snowing beyond a simple copy and paste, but for best results be sure to be using a white-on-black Terminal theme like “Peppermint”, “IR Black”, “Pro”, or “Classic” to get white snow flakes, otherwise you’ll end up with some funky colored snowflakes that aren’t exactly festive…

The infinitely useful instant preview tool of Quick Look has been a feature of Mac OS X for quite some time now, and users have long been able to use either a key modifier or multitouch gesture to zoom in and out of the Quick Look preview windows of an image or PDF file.

Many of us have an iPhone sit on our nightstand to use as a primary alarm clock. But over time, with schedule changes, early flights to catch, sound changes or new music selections, sleeping in on some days, waking up early on others, the iPhone alarm clock can get extremely cluttered with way too many alarms for just about every conceivable time. Furthermore, as you migrate from old iPhone to new iPhone, these alarms will transfer with, which means you may be retaining an ancient alarm time that was set sometime in a prior presidential administration for a long forgotten reason. If your Clock apps alarm section is cluttered up like this, you’re certainly not alone, but fortunately there’s a very simple way to remove every single alarm and start from scratch; just ask Siri.
