Do You Need to Defragment a Mac’s Hard Drive?

--> Do You Need to Defragment a Mac's Hard Drive? About Focus on Macs In my mailbag this week, I found a couple of questions about defragmenting a Mac's hard drive. This question usually comes from new Mac users, or individuals who switch to the Mac from the Windows environment, where disk defragmentation utilities abound. Some individuals want to know which third-party disk defragmentation app they should use, or wonder why there is no defrag tool in OS X. Courtesy of Apple OS X does have disk defragmentation capabilities, but they're built into the system rather than a separate tool. Since OS X 10.2, Apple has included automatic defragmentation in the Mac OS.

Learn To Code

Even if just to get a better understanding of how computers work or learning how to customize your browsing experience, knowing the basics of coding opens ones eyes to possibilities once only known by a few.  Learn To Code Planet Cocoa If learning to program is even a minor goal for you,  Code Year (via  Brent Simmons ) might be just the encouragement you need.

I'm one of those computer programmers who downplays the difficulty of the profession, because "if I can do it, anybody can do it!" On the other hand, I have faced challenges that made me question whether I'm vaguely qualified for the job. What it boils down to is that programming is both incredibly simple and impossibly hard, like so many important things in life. There was a time when nobody knew how to write literary prose.

Tips: Delete duplicate entries in "Open With..." dialog in Finder

Duplicates!!! When you control+click (or right click if you have enabled that option) on Mountain Lion, and there seems to be several duplicate applications listed and/or apps you no longer use, here is a Terminal shell script that will fix that.  Just copy and paste the code below in a Terminal window. /System/Library/Frameworks/CoreServices.framework/Versions/A/Frameworks/LaunchServices.framework/Versions/A/Support/lsregister -kill -r -domain local -domain user (Terminal can be found using Launchpad or Spotlight) After pasting, hit the Return key and allow time to run, then type "killAll Finder" without the quotes, and Return.  This will rebuild the "Open With..." menu.   If you do not see an immediate effect on the lists, restart your Mac.   Should be no need to restart. (Thanks, JK) Duplicates and old apps gone! If you wish, you can make a Service that will do it using Automator as well: Open Automator (Launch Pad or Applications folder) Create...
