As some of you already know I recently bought a new MacBook Air and with it I
bought the MacBook Air SuperDrive. The MacBook Air SuperDrive is the first
Apple product I bought and feel stupider for buying it. Obviously, because I am
stupid and assumed that apple would create a good external CD/DVD drive that
would work with the MacBook Air.
It seems that the MacBook Air SuperDrive only works when directly connected to
the MacBook Air. Hence, no using the external SuperDrive with USB hubs. Beyond
that the MacBook Air SuperDrive doesn’t work on non MacBook Air laptops. After
googling a bit some people think this is because Mac is using it as a loss
leader for the Air and don’t want to support it as a general external drive. I
think this horrible from a product perspective because the MacBook Air only has
1, thats right 1 USB port.
Hence, when you run into a situation like today where I was installing some
printer drivers and software and their installer expects you to be able to plug
in the printer as a step in the wizard it gets a little tricky. Luckily, I was
able to quit out of the installer disconnect the MacBook Air SuperDrive and
connect the printer and get it working with some extra effort.
Anyways, the point of this story is that if you buy a MacBook Air, do not, I
repeat DO NOT, buy a MacBook Air SuperDrive. You are much better off just going
and buying some other external DVD ROM/Burner that will work on all your
machines and via a hub.
So as a result of my 17in Mac Book Pro Battery expanding and my second battery
starting to approach the same level of expansion I decided that I would use
this as an excuse to upgrade my, I think, 4 your old 17in Mac Book Pro with a
much smaller version as I have been coding all over the place lately. I have
been going to Ruby group meet ups, private project development meet ups, and
just wanted to get out of the office and do some coding. Hence, I bought one.
Thats right, a MacBook Air. You can see the two machines side by side in the
Initially I thought I was seriously going to hate the small screen but then I
thought about it and decided what the hell I should just take the leap and
adapt as is required with most things. So, I did. Let me tell you there is
something about having lots of screen space that was holding me back from using
Spaces. My original background was Linux which has had the same concept as
Spaces for as long as I can remember. I had no problem using virtual desktops
(a.k.a. Spaces) when in Linux but I could never really get the feel for using
them with my 17in. But, now that I have a tiny little ultra light weight sexy
beast of machine that has a tiny 13in screen, I LOVE Spaces. I stay more
organized this way and have a lot less clutter in my environment.
It blows me away that reducing my screen size has had so much of an effect on
my workflow and organization, and in a positive direction at that. Crazy,
anyways I will make posts on any tricky things I have found I don’t like or
love about the MacBook Air as my usage of it progresses.
So I setup my MacBook Air right after I got it and was just using the basic
functionality. I then realized that I needed root to do something. Yep, you
guessed it, I some how managed to to fat finger my root password when I setup
the initial Admin user in the setup process. This is normally not a big deal as
you can always put the DVD back in and rerun the setup wizard to create a new
user. However when you are a MacBook Air and have no DVD drive it gets to be a
tad bit more complex.
The key is single user mode. After some googling I found that you can easily
get into single user mode on Mac OS X simply by rebooting and right after the
Chime noise holding Command-S and it will start you up into single user mode.
For details on single user mode please go
When you see the prompt for single user mode it will tell you two commands to
run to make it so that you can modify the file system. One is a fsck command
and the other is a mount command. I simply ran the two commands as the info
above the prompt instructed me to. Once it was done running those commands, I
ran the following command and rebooted so that it would start the initial setup
process over again. I did this because I knew that if I created a new Admin
user and knew its password I could then sudo in and change the password of my
existing Admin user that I previously fat fingered the password for.
I know that there are command line tools that allow you to change passwords,
etc. in Mac OS X, but for some reason I wasn’t feeling like looking up the
directions on how to use them. Hence, I just did it this way. Figured I would
share my find on Single User Mode, :-). I am sure someone has already found it,
but it is new to me.
Well, today I woke up like any other day in my life. I start by pulling my 17in
Mac Book Pro out of my laptop bag. However, today I was greeted with a bit of
surprise as you can see from the following photo.
It seems that my 17in MacBook Pro battery had decided that it was going to
expand while it was out of my laptop. Thank God it was out of my laptop. Who
knows what kind of damage it would have caused if it was in the laptop when
this happened. Luckily this was a spare battery as I have 2 batteries for my
17in MacBook Pro. I swap them out fairly often so that I have a charged extra
battery in my laptop bag and the other stays in the laptop. I guess I won’t be
doing that for a while .
I am somewhat disappointed. I have had this laptop for a few years at least but
it still works like a champ and I would have thought that the battery would
have failed from a charge holding perspective before the battery just decided
to expand. Anyways, very strange so I figured I would share my surprise from
this morning with you all. The sad part is that my other battery, the one
currently in my 17in MacBook Pro, has started to expand as well. The aluminum
shielding is bowing which means I am going to have to spend $129.00 on a new
battery for my laptop. Oh, well, such is life.
Apparently this was a known issue according to friends of mine at work and I
just didn’t know about it till it happened to me, :-). My friends also informed
me that Apple supposedly fixed this issue with all their new batteries so if I
buy a new battery it shouldn’t happen with that new battery.
Lets hope that they are right.
