Zend Server Free Edition is also available on OS X, and you can download it from tinyurl.com/zendfree as shown in Figure 2-15. If there is a problem with that short URL, try entering http://zend.com/en/products/server/free-edition.
I recommend that you always download the latest stable release (in this instance, it’s 6.01/PHP 5.4 for OS X), which will be listed first in the download section of the web page, which should display the correct installer for your computer out of Linux, Windows, OS X, and IBM i. You may be asked to log in before you download, but you can also click a link to get the file without logging in or registering, although you’ll miss out on product update emails and other news.
Once downloaded, double-click the .dmg file, wait for the download to verify, and then wait for the window in Figure 2-16 to appear.
Here you can double-click the README file for instructions, or double-click Zend Server to open up the installation window shown in Figure 2-17.
Now click Continue. Read the instructions ...
