Works great on my Macbook Air Mountain Lion. I am looking for the Diagram solution on my Mac, originally, I choose Libreoffice, but it's too fat. Then I try Dia and now it's my favorite.

I hate to down-rate the entire project because of the installer, but ... why in the heck do you need to install XQuartz if you've got the latest version of OS X? From the XQuartz site: "Together with supporting libraries and applications, it forms the X11.app that Apple has shipped with OS X since version 10.5." I have 10.9.4, so it's already installed. Why doesn't the program find it?

basic editor for basic diagrams, if you want some serious stuff, than look elsewere.. what i do mostly in dia is drawing state diagrams, with this complaints: - line routing is really bad, i spend so much time with just fighting routing algorithms in dia, with poor results, this is really the deal breaker, - lock to edge point doesnt work, i want to stick the line with one of edge points, but when i grab the line, than i grab the line and the end point doesnt stick to the edge of element, this is really another deal breaker, - some serious UI problems (Enter doesnt confirm some mostly used dialogues, i have to click or use a shortcut), - no much other features, - development doesnt exist, no new version for several years, probably abandoned application.

Very great tool, easy to use and powerful at the same time, but there are two features i would like to see, if possible!! - Modify only a part of text in a box (now you can modify only the entire box) -Select text in a box (now you can't select text in a box)
