Check MacBook Air SSD Model

I just received my new MacBook Air 13.3″ (MC965LL/A) and I heard that they put in 2 different SSD’s in each one. I found the best way to check which drive you have, and which is technically ‘better’.

Go to : Apple Menu > About This Mac > More Info > System Report > Serial-ATA.

You should see something called APPLE SSD :

If it is TS it is a Toshiba and probably a bit slower. If it is SM, it is a Samsung drive and faster.

Check MacBook Air for LCD Model

Not only are there different SSD’s in the new (MC965LL/A) MacBook air’s, but they also seem to have different LCD’s. Everyone seems to think the Samsung is better looking, but here is how to check

Launch the Terminal Applications – > Utilities
Copy and paste the following command onto a single line and hit return:

ioreg -lw0 | grep IODisplayEDID | sed "/[^<]*

If it starts with LP, it is LG, if it is anything else, it is Samsung. Like mine, it is Samsung :

How to disable safe sleep in OS X (Lion)

I wanted to get rid of safe sleep, aka hibernation on my new macbook air (MC665/AMC965LL/A)

Apparently they make a few programs that do this for you, but they do not remove the large safesleep file, they only disable the sleep mode.

To disable safe sleep mode: sudo pmset hibernatemode 0
To remove the sleep image file: sudo rm -rf /var/vm/sleepimage

It’s as easy as that, and with the Lion auto save and resume feature, there really is no need to waste that much SSD space! Make sure to not let your laptop battery die either!

How to burn dmg in windows 7

I got a 2006 Macbook Pro, which had 0’d out hard drive. So I wanted to get OS X loaded on to it. I found a dmg file that had OS X 10.6. Doing a quick Google search, I figured out I can easily burn the dmg file to be bootable.

What you need first is the application for your windows computer :

You can download the application from here :
or you can download the version I used here :

You then run it, and get a 15 day free FULL trial, so you can use all of the capabilities the software has to offer. If you like it, I always advocate purchasing/paying for great pieces of software like this.

Very easily open the application, click run, unless you paid for it. You then need to point the application to your dmg file.

Now select your dmg file, and then you have it loaded into transmac, very similarly like in OS X environment. It almost looks as if it mounted it, but from what I can tell, it does not actually mount it. You can then right click and burn (assuming you have a sizable DVD/DVD DL inserted).

Pop it into your Mac, and you have a bootable DVD from a dmg file coming from a Windows environment.
