How to Make a Bootable OS X Yosemite Beta USB Install Drive

Now that the OS X Yosemite Beta is available to the public (you can still sign up and download it if you’re interested in running the beta release on your Mac), you might be wanting to make a bootable installer drive out of an external USB flash disk to make installation easier. Sure, you can always just copy the “Install OS X Yosemite Beta” application to other Macs and run it directly from the Applications folders of different machines, but the bootable installer option allows you multiple benefits; you can erase and partition drives directly from the bootable drive, you can perform clean Yosemite Beta installs, and you can make a single USB key to install Yosemite on multiple Macs. These aspects make installer drives preferable for many advanced users in particular, but it can be useful for everyone, even novices.
Quick side note: if you’ve been having problems downloading the Yosemite Beta, try these tips to resolve the download issues.











QuickTime Player, the video player and editing tool bundled with the Mac for ages, received a fairly major overhaul when it turned into QuickTime Player X. While it became free and lost the need to upgrade to a Pro version, it also lost out on a lot of really nice professional features that QuickTime Player 7 had. Perhaps most missed from QuickTime Player 7 is the excellent A/V tools panel, which allows users to adjust the video brightness, color, contrast, tint, playback speed, audio volume, audio balance, bass, treble, pitch shift, and playback.
If you ever need to quit out of more than one app on the iPhone, or quit a bunch of apps quickly in iOS, using a handy multitouch swipe gesture at the iOS multitasking screen is enough to quit apps simultaneously. This works really well to quickly clear out the multitask bar of all running apps if you need to for whatever reason, and you can quit as many apps at a time as that fit on screen (and that you can fit fingers onto), which usually means killing running apps in groups of three.
