I use TexStudio v.2.5 on my personal machine with the latest MacOS. The spell checking feature says "no dictionary found" nor is there a thesaurus found. It is unclear to me where these dictionary files are located, if at all in the MacOS version of TexStudio. I also use TexStudio on my PC at my job at school, and the spell check feature is already set up and automated and works fine. Please help address this issue because I would like to use TexStudio on my mac.
