Macbook Tricks.

For years, I have been extremely skeptical about Apple products. In my opinion, they have primarily been pushing lifestyle tech to people without computer skills.

It is, however, undenibly that Apple has aquired such a large portion of the market that they cannot be discounted.

I have recently aquired an 11.6'' Macbook Air in order to learn about Mac Os X. Therefore I have made this page to help keep track of stuff i need to remember.

Partitioning and undoing this.

In general, it is very easy to do partitioning using the build DiskUtil. Note that Recovery partitions are in essence a safestate you can boot which will hopefully help you to get your system running again. I currently have two recovery partitions, as fairly quickly updated from to Yosemite, which forces installation of yet another recovery installation (as the one from the previous OS is not removed) both are bootable.

Creating USB install media for Yosemite.

First download Yosemite image from AppStore. This will cause the image to be stored in /Applications/Install OS X After downloading, App Store wants to initialize installation. Do not do this, as the image is wiped as part of the process.

Instead use the createinstallmedia tool. The syntaxt is:

sudo /Applications/Install\ OS\ X\ --volume /Volumes/USB-mount-name --applicationpath /Applications/Install\ OS\ X\ --nointeraction

An 8gb usb should be sufficient. After completion you will get a "done" on the commandline.
