After working from home for over a year, I decided to upgrade my workstation to a treadmill desk. Programming and walking at the same time is quite fun, but was a bit of a challenge at first.
If you encounter this problem then try turing off snapshots and then running the wizard again. That fixed the problem for me.
To turn off snapshots go to File > Project Settings > Snapshots.
I’ve reported this bug to Apple. Not sure yet if others have encountered it.
After I had installed Ubuntu 10.10 on my Asus A52J laptop, I had two issues
1. The sound wouldn’t play through headphones when I plugged them in.
2. May webcam was upside down in Skype.
I found the answers in these two forum posts:
1. Create file /etc/modprobe.d/sound.conf, and enter the following:
options snd-hda-intel model=ideapad
2. Reboot (or reload snd-hda-intel)
Skype cam problem
To fix the cam in Skype, create a bash script in your home directory
#!/bin/bash export LIBV4LCONTROL_FLAGS=3 && LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so skype
Here is what I did to setup Snow Leopard with xcode in Virtualbox and deploy my work to my iPhone.
I’m running Ubuntu Linux on my Asus A52J laptop with an Intel i3 CPU and 2 GB of RAM
UPDATE: Virtualbox 4 keeps aborting when I add my iPod to snow leopard. I’ve reverted back to using version 3.2.12. Please let me know if you get it working in version 4.
Install Snow Leopard
www.sysprobs.com has many useful tutorials for installing Snow Leopard in Virtualbox. I used this one for installing it on my Intel i3: http://www.sysprobs.com/mac-os-snow-leopard-intel-i3i5-i7-processors-virtualbox
You will need a copy of snow leopard. I first downloaded a copy of Snow Leopard and then purchased a copy after I had confirmed everything was working. If you decide to do this then please don’t be a pirate by not purchasing a copy after you have everything working. You can probably pick up a secondhand copy of Snow Leopard somewhere for a good price.
You will also need eboot.iso because Virtualbox will not be able to boot directly into Snow Leopard.
Next, download Virtualbox and create a machine with the following setup:
Start the virtual machine and boot from the eboot.iso, and then inserted the snow leopard DVD and mounted it. Then hit refresh and press the right arrow key to select it and hit enter.
Once the installation screen appears, select English and in the next screen go to the disk utilities and create a new partition on the virtual hard disk. Then install snow leopard on it.
Upgrade snow leopard and install MultiBeast
Xcode requires 10.6.3 or later. If your version is less then you’ll need to upgrade.
Download the 10.6.5 upgrade and MultiBeast to your snow leopard installation.
Install the upgrade and when it tells you to restart your computer at the end, DO NOT. Instead install MultiBeast and then restart. If you restart after the upgrade but do not install MultiBeast, then you may experience problems, like your mouse no longer working!
Installing Xcode and the iOS SDK
You can download xcode with the ios sdk from the apple website. It is a big file, around 3.5GB.
Install xcode. This should be fairly easy provided you have enough space. After installation it will take up almost 10GB!
Deploying your work to the iPhone
There are two ways to do with. The first option is to pay Apple $99. This is definitely the easiest option and probably the best if you are sure you will release something to the Apple store.
The other option allows you to test your work for free, but it does require a jailborken iPhone.
Install AppSync on your iPhone via Cydia.
In snow leopard
Applications > Utilities > Keychain Access
Certificate Assistant > Create a Certificate
Create new certificate
Name: iPhone Developer
Certificate Type: Code Signing
Accept defaults for everything else and click continue until certificate is created
Replace all instances of XCiPhoneOSCodeSignContext with XCCodeSignContext
In xcode: Project > Edit Project Settings > Build
Set code signing identity to the certificate you just created.
Also, to deploy for earlier version of iOS, like iOS X 4.1. Change deployment version
Setting up a shared folder
You’ll probably want to transfer files from Linux to snow leopard at some stage. The easiest option is to use NFS.
sudo apt-get install nfs-kernel-server vim /etc/exports
I added the following line to the exports file. The * means anyone can mount it.
Ideally you would want something like this
But I couldn’t seem to get this to work. NFS is still quite new to me.
After editing the exports file you need to reload the settings:
sudo /etc/init.d/nfs-kernel-server restart sudo exportfs
Now in snow leopard open a terminal and mount the shared dir:
mkdir dir_to_mount_shared_dir_on_snow_leopard mount ubuntu_host_name:/home/your_name/shared_dir_on_host dir_to_mount_shared_dir_on_snow_leopard
You may want to add this to a bash script for future.
Disable Screen Saver and Power Management
If snow leopard crashes after it is left alone for about 10 minutes, it could be because of the screen saver. It was in my case.
Under settings, disable the screen saver and the energy saving settings which turn off the hard drive and monitor.
Completely close Virtualbox and then enter this command from the terminal:
VBoxManage setextradata “VM name” “CustomVideoMode1″ “1280×800×32”
Replace VM name with the actual name of your virtual machine and likewise for the screen resolution.

The sound quality might not be perfect when you get it working, but it should be sufficient for development purposes.
