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 Service (Gear Icon)
Make new Service using Automator
Next, add a Run Shell Script step and type in the code above.  (Paste it in if you want to save typing and reduce errors.)
Then add another Run Shell Script with the killall Finder command.
Save as a service with a name you choose. Then Select from the Services menu when you need it.

Good tip! There's one way you can have it take effect without having to restart your Mac. After the first command in Terminal, do a second command killAll Finder When Finder comes back the duplicates will be gone.

I've had the same issue. Evernote and Pixelmator seem to be the biggest offender for this. Is it the way they update? I have no idea.

Rumor Mill: New mac Mini Coming?

There are reports all over the Internet about a new Mac Mini to be possibly released at MacWorld.  TUAW is reporting that a new version of the Mini will include an optical drive that can be swapped for a second hard drive.  The housing will look much like the Time Capsule with a "lip" for consealing the optical dive slot and cooling. Whether true or not, I would like to see a few features in a new Mac Mini. More RAM (Of course.) NVIDIA chipset. FW port for external HD My main use for a Mini would be for media.  A Mini on my network using Front Row would be great for movies and TV.  (Sorry, Apple TV.)

Calculate Age or Years Elapsed in an Apple Numbers Sheet

Often it is useful to show a person's age or years elapsed since a start date.  For example: Hire Date: 4/1/2012 - Years of service: 1.5 Here's a formula for Numbers that will do the trick: =IF(ISBLANK(cellReference),"",DATEDIF( cellReference ,TODAY(),"D")/365.2425) Replace the cellReference with the actual cell reference. i.e.: (A1)  So here's the breakdown: =IF(ISBLANK(cellReference),""  --- this checks to see if there is a start date in your referenced cell.  For example say your spreadsheet has a cell (A1) that holds a date of birth, but it is not yet referenced, this will result in an empty string. (Blank cell) Otherwise, it calculates the years:  DATEDIF( cellReference ,TODAY(),"D")/365.2425) DATEDIF compares two dates. The first date is your cell reference i.e.: (A1) The second is the current date according to your computer, iOS device: TODAY()  returning the Day -  "D" Then the difference is divi...

Acid3 Test

I did an Acid3 test with a few browsers and these are the results I got.  For those unfamiliar, as I understand it, Acid3 is a test to see how compliant a browser is with current standards with the W3C . Browser # 1: Chrome by Google.  Running under Windows Vista Home on my Mac in VMWare. 79/100 Not bad for a new browser.  I'll be curious to see what the Mac version will do when it comes out. Browser #2: Firefox v.3.0.1 Mac OS X 10.5.4 71/100 Not as good as Chrome, but I have a PILE of extensions on Firefox. Browser #3: Safari 3.1.2 Mac OS X 10.5.4 75/100 Better than Firefox but still lower than Chrome. My take is overall they seem to perform about the same but I'll stick with Safari for now.  I use Firefox for much of my web browsing, but Safari is fast becoming a close second. Someday, maybe I'll test Opera too. Cheers!
