OS Mavericks

I did my OSX Mavericks update after my vacation back. I got the OS installer a few days after its release. I hold on the update because I want to wait for information of how to create an installer.

Create Bootable USB Disk

Here is the instruction of making an OS X Mavericks installer:

sudo /Applications/Install\ OS\ X\ --volume /Volumes/Install\ OS\ X\ Mavericks --applicationpath /Applications/Install\ OS\ X\ --nointeraction

Where I named my USB disk as "Install OS X Mavericks".

Install Mavericks

Before starting the installation, make sure you use Time Machine to do the last back. I will need to use migration app to transfer all my applications, accounts and other data to the new OS.

With this USB installer ready, I set up my boot disk from System Preference|Startup Disk:

To do a clean installation, I use Disk Utility to erase my Mac HD first. Then I start to install OS X to the HD. It took about 1 hour to install Mac OS. After that I choose to do migration by transferring accounts, applications from Time Machine. Depending on how much data, it may take several hours to do the transferring.

Here is the space difference between before and after for the update:

Command: df -lakUsed(Kilobytes in 1024-blocks)
Difference (A-B)-3,339,620
