Font Problem using MathType
I need to write some papers with mathematical symbols and have been trying to use MathType. I get an error when I start up the current version of MathType. A window pops up that says:
"MathType requires a newer version of the MT Extra font that is currently installed. Please reinstall MathType to get the current version or [instructions for disabling the Apple font]."
I tried deinstalling and reinstalling MathType and still get the same error. I tried disabling the Apple font and that didn't work. I called MatType support and they gave me instructions for installing the MT Extra font from the Applications>MathType 6>Fonts>TrueType folder. I did that and got a pop-up window which looked like a preview of the font: symbols such as universal quantification. After a few seconds a window appeared that was titled "Font Validation". It said:
"1 serious error was found do not use this font". There is a button at the bottom of the window that says "Install Checked" its greyed out but if I select MT Extra in the Window it still gives me the option to click the button.
I didn't go ahead and install the font though since that sounded like a serious error. I asked MathType support and they said not to worry about it and just go ahead and use the font. However, when I go ahead and click on the "Install" button in spite of the one serious red warning, I get ANOTHER warning saying something like:
"doing this could seriously harm your environment, including system crashes."
I'm asking the MathType people one more time but thought I would as here. Does anyone know why I'm getting these errors and more importantly is it really fine to use the font? Are there other ways besides MathType to get math formulas? I don't need many, mostly just for First Order Logic, Set Theory, and Summation.
I'm on an iMac running OS 10.11.5 (the info in my profile is out of date, will fix that) and using Apple's Pages product version 5.6.2
I would appreciate any suggestions here.
