My computer has been getting ve-ry lag-gy late-ly, so I was hunting for ways to streamline memory. I knew that the many extra language modules built into Mac's OS take up huge amounts of memory, but I wasn't sure how to root them out of their myriad hidey holes. Then I found a nifty piece of freeware called Monolingual that, with the click of a box and push of a button, does just that. So I off-loaded Estonian, Faroese, Lithuanian, Thai, and many more... and freed up ONE GIGABYTE of space. Suddenly my computer, instead of performing tasks like a teenager asked to do chores ("Oh...do I HAVE to?") is zipping along like a hyperactive corporal ("Ma'am! Yes ma'am! I'll get right on it!"). Here's where to get it if any fellow Mac users want to tame their babel...
http://monolingual.sourceforge.net/index.php Mind you, I did leave Klingon on there, just because it amused me too much. Yep. The Mac OS includes Klingon.
Edit: apparently one should be sure to close all applications before running the program. And be careful not to delete any version of English, or it will cause problems!
