Thank you Michael and John for your patience in helping me understand better what I'm seeing on my machine. I just used Everson Mono to type some Hebrew in Pages, Bean, TextMate and TeXShop, opened the Fonts application for each, went to typography, made sure Common Ligatures (the only option) was ticked off for each, and indeed couldn't turn off the alef-lamed ligature in those applications.
