I have both Tex-Live 2020 and 2019 installed (MacTeX 2020 and 2019). Tex-Live 2020 is the default.
Once in a while I need to use tex-live 2019 instead of 2020. For this I: i) open the Tex-Live graphical interface and switch the default distribution to 2019; ii) run (pdf)latex; and iii) switch distribution back to 2020.
Is there a way to either:
- Make “latexmk” use Tex-Live 2019 without switching the default?
- Switching the default from the command line?
