Recently, I tried creating an OSX Virtualbox VM on my macbook. Creating a virtualbox VM should be easy, I guessed, as I am just looking to run an OSX guest on an OSX host. Not trying to create a hackintosh here.

However, it turned out to be more tricky than I anticipated. For starters, I needed a bootable iso of the OSX operating system, but Apple does not provide one anymore. So this is what I had to do...

I searched around on google and ran into many useless pages. Finally, I found one that had a useful solution.

I replicate the instructions here, in case that website goes missing.

Step by step instructions

Look for Install OSX Yosemite.app in your /Applications folder. If its already there, you can save on a large download.

Here are some useful git config options for

1. Displaying colors in status and diff outputs.
2. Creating aliases and shortcuts for common git commands.
3. Setting shortcuts from the command line itself.

First, create a ~/.gitconfig file for your user account, which will store the changes we are about to make.

touch ~/.gitconfig

sudo apt-get remove overlay-scrollbar
sudo apt-get remove liboverlay-scrollbar-0.2-0
sudo apt-get remove liboverlay-scrollbar3-0.2-0

Often, my work involves sharing a folder in my Ubuntu vm to access it from the host machine, and every once in a while, samba refuses to play ball (Samba is the one who is in charge of sharing folders).

Here is how to fix the problem. After enabling the share in the folder properties (keeping guest access off), we will have to give explicit permissions for a user to access the shared folder.

Suppose your username on ubuntu is testuser. Type the following commands to give access to the test user...

$ useradd -N -M -g sambashare testuser

$ smbpasswd -a testuser
