I tried several options again to get this to work. In MathType preferences, as noted by an earlier post, there is an option for Evernote. When I select this, the copy an equation and paste it into a note, the app pauses, spins the rainbow wheel and launches a window saying Downloading content... And...nothing. I've tried setting the preferences to PICT and PDF but these come in at such a large size that it is impossible to use.
I've rebooted Evernote and MathType after changing settings and this behavior doesn't change.
Others have suggested modifying Evernote to accommodate Markdown. I don't really use Markdown directly, though I realize MathType uses this easily/natively. So, just fixing this "missing feature" would be very appreciated.
BTW, I'm using the mac desktop app to do this.
Any advice would be appreciated. This keeps me from using Evernote as my main research documenting tool.
