Chris Heard has put together two screencasts demonstrating how to setup and use your Mac to type in Hebrew. You might want to be sure you have the unicode SBL Hebrew font installed before you watch the videos. The font is available free for download here. Be sure to also download the keyboard driver and PDF manual. You don’t need to use the SBL Hebrew keyboard drivers, but Chris does demonstrate them in the screencast. Thanks, Chris, for a great resource!
