MathMagic Personal Edition for Mac

A real very very good equation editor. Since version 9.8 I can use it in Catalina and Big Sur without any problem. Installation is easy and the usage too. It handles very complex formulas and therefore I thank the developers very much.

As a teacher of English and history who somehow seems to end up teaching a maths class (Australian, so not "math", but not big deal), I find MathMagic a lifesaver. Equations in MS Word are not awful in my experience, but MM is the next step up. It's flexible and very powerful, and I have always managed to come up with the expressions or equations I've needed when writing information sheets, or setting class work or assessment tasks. Not the cheapest, but when you consider the cost of the fonts alone if you bought similar separately it suddenly seems to represent pretty good value indeed. Highly recommended.

Very nice math equation editor overall. No installer. Drag and drop install type app but their fonts should be installed separately so there is one more step. Does not come with the latest Mac OS X features such as QuickLook, Spotlight, Lion's auto save, .... but not a big deal. Does not run after the free trial period, while MathType still works in a simplified version.

This must be the best equation editor for the rest of us. Actually too much feature. Though I can still remember some TeX expressions for some commonly used symbols, I feel more comfortable with this kind of UI assisted equation editor when I need a few equations from time to time. Good thing is that I can just drag equations(mostly worked well but some equations needed some retouching) from wiki web pages on to math magic window. This saved me a lot of time. Text-to-speech for equation is an interesting try. Needs more work for this TTS - their math reading syntax is not like natural math notation, variables are read by char. Their default fonts are not my type but it lets me use my own fonts. Applying color was easy - equations look nice in Keynote. Overall, great app. Definitely worth a try, if you do not have a LaTeX package already installed.

One word: LaTeX. Free to install. Free to use. Comes with a great equation editor.
