It’s\u00a0been a very long time since I posted anything, so it’s my new year’s resolution to do more this year. This first post of the year will be a computer post. Over the holidays I picked up a MacBook Air, and I have to say I love the design. Some of the highlights include:\u00a0back-lit\u00a0keyboard, multi-touch trackpad, fans & speakers hidden in the joint between the display and the keyboard & aluminium case. Apple really does a great job with design. But of course, I hate the simplicity of MacOSX. Yes I know it’s built on top of Darwin, but I like to be able to tinker with “everything” and run all my favorite programs. So the first thing to do when I got it was to delete everything and put on Linux. I won’t go through every detail, but I will mention the things that did not work out of the box. Hope this helps someone else!<\/p>\n

\n# MacOSX fixes – Do this before

\n##################################<\/p>\nIf you use only Linux, boot hangs for 30 seconds waiting for the Mac partition. To override this issue the following command (from MacOSX):
\nbless \u2013device \/dev\/disk0s1 \u2013setBoot \u2013legacy \u2013verbose<\/p>\nTo stop the boot mac sound, issue the following command:
\n\/usr\/sbin\/nvram SystemAudioVolume=%01<\/p>\n##################################
