Enable/Disable bluetooth via cmd line

Since I got my new MacBook Pro 13", I found I constantly lost the connection with my bluetooth devices, like mouse or keyboard. It is so annoying that I have to reach my touch pad to disconnect the devices and re-connect them from the status bar or system preference. You'll know what I am talking about if you have the same problem as what I have. It is pretty pain.

Today, I found a command line tools for you to enable or disable the bluetooth, it is so handy. I just love it. Here is the link for blueutil.

Now, I can just issue the command: blueutil off and blueutil on, I am back on track again.

Restore from time machine

Just got my new Mac Book Pro 13". It is REALLY pretty.

I was hoping the migration would be a breeze. But it turns out there is a catch.

Here is the little background. I have a Mac Book Pro 15" which was purchased in April 2008 ( 4GB, 2.6GHZ, 250GB ). I loved it, the only thing it missing is the multi-touch track pad, of course, it is not a uni-body. But I want the new 13", you know it would be nice to have if you have to carry it for some business trip.

First, I made a full backup of the 15" to the time machine. Then put in the installation DVD on 13", after reboot, I wipe the SSD drive and then from the menu bar selected Utilities > Restore System from Backup...


This brought up a dialog to let me select the Time Machine


Once you've selected your Time Machine volume, you can select which snapshot to restore from. I followed steps, and after 2 hours, it was done. Once it rebooted, every thing works fine, there is only one catch - no sound. You can hear the chim when starting the machine, but no sound devices found when you go to "system preferences". After googling for about another hour, tried several solutions. None of them worked for me. I guess that just is the driver's problem, but I have no idea which library to put onto my new machine. So I gave up searching, and re-do the installation. It turns out it is quite simple, the lesson I've learned is "Do not migrate a whole system, just the user account if you have different machines". Here is the steps:

Do are regular installation, once reboot, choose to migrate a user account from your time machine. After that, every thing works great!

A little thought about the better way to do it. The way that I did which migrated all the iWork08 to my new machine, although I can reinstall the iWork09. I was thinking maybe I can create a dummy user, login, do all the update and install all the new programs, then delete the dummy account, reboot, then migrate the user account. That would save me a lot of time. Maybe when snow leopard out...

Smart Sleep - Mac OS X

I can't remember since when Apple decided that when you sleep your laptop, it will write all the data in memory to the hard drive, then go to hibernate. It is a good thing if you are on road, and want to change the battery. Once you power it on, every thing just like before you swap the battery. But for me, I've had 4 apple laptops, I've never done this for a single time. Especially for my latest MacBook Pro, I have to wait it to dump 4GB memory on to hard drive every time. And most of the time, I found it is even faster if you just power off it. I would be more happier if it can go to sleep right away when I close the lid.

Now, you can do that - SmartSleep PrefPane. I've been looking for something like this for a while. Why I love it, you know, now, I can get home 5 mins earlier every day. :-)
