I installed MacTeX-2019 distribution and, as the title says, I don't have the Theme tab in the preferences panel of TeXShop which allows me to change the source page colours. Moreover, the "OK" button doesn't close the preferences panel once I click it.

  • What OS version are you using? Are you sure you’re using TeXShop 4.27 since the Preference Panel you Show is from an older version of TeXSop? Jul 16, 2019 at 15:52
  • The OS is 10.14 and the TeXShop version was indeed 4.27

I ended up downloading just TeXShop from the University of Oregon website and I replaced the application. This fixed the problem and now the preferences panel works correctly and has the Themes tab. I thought that maybe there was a problem in the TeXShop provided by MacTeX.

  • Do you have more than one version of TeXShop on your system? Jul 16, 2019 at 15:54
  • No, I had only the 4.27 version that I installed through the MacTeX 2019 distribution.
