The title says it all!

I already have ChemDraw ultra but I'm interested in other free, light software that will just do the essentials - draw molecules, mechanisms etc. If anyone can suggest any I'd be more than happy.

I know MarvinSketch has some free, java based program like the drawing tool it has in Reaxys but I failed to install it on my iMac.

I can't recommend a free one since I never found a free one for my mac that really worked well. But I can recommend a decently priced one that gets the job done is chemdoodle http://www.chemdoodle.com/. there is also chemsketch that a lot of my windows using friends use. not sure it works for mac since I heard about it after I got chemdoodle.

If you find something free that you like let me know
