  • pdf-tools

    Emacs support library for PDF files. (by vedang)

  • I installed pdf-tools from the emacs interface itself, supposedly from https://github.com/vedang/pdf-tools/. And the pdfs are not being viewed in DocMode. My emacs is version 28.1, and I got it from homebrew iirc.

  • homebrew-emacs-plus

    Emacs Plus formulae for the Homebrew package manager

  • So, I dug into this issue a bit more. As per the tip by \u\HumanBrainMapper, I went to check which emacs mac port am I using. I was using the package emacs-plus from https://github.com/d12frosted/homebrew-emacs-plus. Looking at this package, I found an open issue which says this particular emacs port does not support high def scaling from pdf-tools : https://github.com/d12frosted/homebrew-emacs-plus/issues/334. Thus, I uninstalled this emacs version and installed emacs-mac from brew (https://github.com/railwaycat/homebrew-emacsmacport).
