No sound out of MacBook speakers & red LED in Headphone jack

yingliang — Sat, 29 Aug 2009 21:32:23 +0000

This is weird, I had the same problem. I found the answer from this forum:

brady.ca: I found a fix for the red light problem. I’m not sure if I like it, but it works. After reading forum thread after forum thread of users that had this problem, I found a dude who fixed his jack with a rubber ended bobby pin. It seems a sensor gets bent (?) and the system thinks your digital external line is still plugged in. I took the butt end of a matchstick and tickled inside the jack. My red light went out. My internal speakers work again. Whatever.

The only difference is I was using a piece of paper wrapped up and … too weird.

What is Lorem Ipsum?

yingliang — Fri, 21 Aug 2009 02:20:21 +0000

Lorem Ipsum is simply dummy text of the printing and typesetting industry.

It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout. The point of using Lorem Ipsum is that it has a more-or-less normal distribution of letters, as opposed to using ‘Content here, content here’, making it look like readable English. Many desktop publishing packages and web page editors now use Lorem Ipsum as their default model text, and a search for ‘lorem ipsum’ will uncover many web sites still in their infancy.

How to stop Safari from asking keychain password?

yingliang — Sat, 18 Jul 2009 18:38:15 +0000

Nearly every time you open a new web page the box comes up twice says: “Please Enter your keychain password”, really annoying! How to stop this from happening?

Navigate to:

Macintosh HD -> Applications -> Utilities -> KeyChain Access

Then go to KeyChain Access (in the menu) -> KeyChain FirstAid

You will be asked to enter your username & password and then you can verify and repair your KeyChain configuration.

If that is not working do the following:

In Keychain Access, choose Keychain List from the Edit menu.
Delete the “login” keychain.

The next time you log in to the account, you can save your current password in a keychain.
