Hello, Most of the symbols that you're looking for come from the Symbol font. The MathType application installs the fonts during the standard installation of the software. Since the fonts aren't properly working, let's take a look at the fonts in the MathType folder. Applications > MathType > Fonts > TrueType You can find Symbol and MT Extra, and double-click on each of them (one at a time) and install them manually from here. It usually will take you to a font validation window, and give you a warning. Proceed despite the standard warning to install them. After you have done so, you can test again. If it doesn't clear up the issue, you should try booting up the computer in safe mode. After doing so, you can re-boot in regular mode. This should also clear the font cache and clear the issue. To boot in safe mode, you can press and hold the "Shift" key when you hear the startup tone. You can release the "Shift" key after the Apple logo appears.
