In case you are wondering if you need to pay $29.99 for every Mac that you own, you don’t.

Purchase a single copy using the same iTunes account, and all your authorized Macs would be able to install. This was actually mentioned in WWDC 2011 keynote.

So, go Mac App Store and download Lion now!

Setting PATH variable in Mac permanently

This post I will highlight 3 ways to change to your PATH variable.

1. The quick way

Firstly, check your current PATH

echo $PATH

If the directory (eg. /my/new/path/) you want to add is not already in your current PATH, then you can easily add with the command

export PATH=$PATH:/my/new/path/

Done. Right?

It’s not really done, if you would like the PATH to change permanently (which is usually the case). This quick method only change the PATH for that bash session. If you close the terminal or open a new terminal, the PATH reverts back.

2. Set permanently for a user

This brings us to the second way of setting PATH permanently for a user.

Edit the user’s bash profile (replace USERNAME)

pico ~USERNAME/.bash_profile

Insert (or edit) this line

PATH=$PATH:/my/new/path/

Press ctrl-x, then ctrl-y, to save the file.

Done.

3. Set for all users

As a bonus, if you want the PATH to change for all users

sudo pico /etc/paths

Enter your superuser password to edit, and insert or edit this link

PATH=$PATH:/my/new/path/

That’s it! Enjoy your path!

Snow Leopard and integrity

Apple latest OS X 10.6, otherwise better known as Snow Leopard, is selling in a few flavors – $29 for single user upgrade, $59 for family pack upgrade and $169 for single user full boxed set.

But no matter which you buy, you get the same disc. You can install it over an existing Mac, or even over a Windows. You can install it once, or one hundred times. It doesn’t matter.

Apple playing the software game in a modern way.

Apple has do away with license keys or other worthless preventive measures. It is now based on only EULA (license agreement) and your integrity.

Apple new policy: Reward honest people with a hassle-free product rather than trying to punish dishonest people by treating everyone like a criminal. Nice policy, I reckon.
