When I blog about applications that I've found I generally wrap up my posts with an open invitation to readers:Many folks have been generous and shared links and applications that I've used to expand my virtual toolbox and make my Mac experience more fun and productive.This time I turned that process around a bit and used Twitter up front. I put out this question: Looking for cool little Mac utilities that nobody knows about... I promptly received replies from a number of people with some cool applications that I had never heard of or tried using. After culling through the list I've pulled out 10 that I felt looked pretty cool. I've included the Twitter name for the person that made the suggestion in case you want to start following them.Need to quickly print out an envelope for someone in your address book? EasyEnvelopes from Ambrosia Software has a free Dashboard widget that does just that. When you want to print out an envelope you activate the Dashboard, start typing the name of someone in your address book, select them and then click on the stamp and you're printing your envelope. Simple, easy and free. Suggested by Jonathan Bernstein Do you have multiple input and output devices for sound? Need to quickly alternate between a plug-in microphone like the Blue Snowball (my favorite) and a MacBook's internal microphone? If that's a common task for you then Rogue Amoeba has a free menu utility called SoundSource that lets you switch inputs and control input volume without having to load System Preferences. Suggested by JT and Marieboyer I'm a copy and paste fiend, grabbing text from various sources and blasting them into my documents and blog posts. Having a clipboard buffer means I can selectively go back through my "copies" and paste in what I want and that's just what Jumpcut does. Small, very efficient and available as open source (MIT license), this was also suggested by Marieboyer If you want to inspect the contents of Package files, disk images or ZIP files you have downloaded to see the contents then Pacifist is a slick way to quickly see what's going on under the hood. Pacifist can also inspect a damaged application—especially one installed by OS X—so that it can be repaired without reinstalling everything. It's available for $20 in shareware form from CharlesSoft. Suggested by Ast A. Moore I'm a huge fan of Time Machine, even though the dorky Time Machine Errors still haunt me. That said, sometimes you don't want Time Machine to wake up and back up your machine every single hour. Maybe you're doing some massive file moves and you want Time Machine to take the afternoons off. TimeMachineEditor, a free utility, is a simple application that merely updates configuration settings. Open it, set it, quit it. Suggested by Doug Smart I like Disk Inventory X , an application I wrote about last year, and several people suggested that again. While I like that tool and the visual display is helpful, sometimes you just want to see a list of files and folders by how much space they take up. Enter OmniDiskSweeper, now a free utility from The Omni Group. It provides a drill down view that's similar to the Finder's column view. The key difference is that it's sorted by the size of the files and folders. Great for quickly finding and pruning out large files that you don't need any longer. Suggested by Marieboyer (yes, she had several excellent suggestions).If you work in a corporate environment (or have kids that like to play with your keyboard at home) and want to quickly walk away from your Mac without logging out and shutting down your applications, MacLoc can help. It's a free utility that leverages the fast user switching feature of OS X so that you can secure your Mac by activating it and walking away. When you come back you will be presented with the system login screen. Once logged in everything will appear like it did when you left. Suggested by Nicholas Leask You fire up Hulu or YouTube and settle in to watching something interesting when after 10 minutes your machine's screen saver kicks in. Frustrating. What you need is something that will keep your Mac awake for a predetermined amount of time. Caffeine, a free utility from Lighthead Software, does exactly that. I'll admit, I had heard about Caffeine before but never bothered to check it out until now.Add it to your menu bar and activate it when you need to keep your machine from falling asleep for 5m, 10m, 15m, 30m, 1H, 2H, 5H or until your turn it off. All the benefits of a strong cup of coffee without the shaking. Suggested by Paul Thompson If you have ever needed to capture a screen shot of a web page you know how difficult it can be if the page is taller than your screen. Paparazzi! is a handy little utility for grabbing the entire contents of a web page. Want to capture that forum thread or blog comments into a single image? Paparazzi! can take the shot for you. While it doesn't work with Flash based graphics it can handle most other types of page elements. Suggested by Alo Lopez Even though my iPhone supports YouTube, there are lots of times that a video I want to watch is on another service ( blip.tv , among many others, is becoming popular). What I would like is the ability to download a really long keynote address from a conference, plant it on my iPhone and watch it while I'm flying or in poor 3G areas. TubeTV is a free application—donations requested—from Chimoosoft that can open a web page and convert Flash based video to a local copy, then further convert it into a rendering option that can be dropped on an iPhone. The conversion can be slow for long videos but if you want to take that video with you this is a nice option. Suggested by Rahil Dowlath There were lots of other suggestions, some that I've written about before like Disk Inventory X . Others—like SuperDuper —I've seen discussed quite a bit so I didn't include them in the list. There is also one that I didn't include that I downloaded and found quite amusing on my MacBook Pro: Oriol Ferrer's Liquid Mac . Thanks to Alo Lopez for making that suggestion!Got an "unknown" application that didn't get included in my list above? An undiscovered gem waiting for people to find?
