I pulled the old material from my Unicode tutorial and the keyboard I had created when I heard Apple was including a Greek Polytonic Unicode keyboard with OS X 10.4. From the Tiger features page, it says,
So, now the answer to the question is simple. Q: How do I type Greek using Unicode? A: Go to the International preferences pane, go to the "Input menu" tab and enable show input menu in the menu bar. Then scroll down the list and add a checkmark to "Greek Polytonic" keyboard. With that enabled, you can used the menu to go from your native language to Greek and back. Set up key combos to switch back and forth on the fly using the Keyboard preference panel.
More Languages and ScriptsTiger includes... a new input mode for Korean and extended system fonts to support Greek (modern and classical)...
