how to install Okular viewer on macOS Big Sur, using M1/Apple Silicon/arm64

okular-appleSilicon.md

1. Install homebrew from https://brew.sh/ (follow the instructions there)
2. tap the https://invent.kde.org/packaging/homebrew-kde/ repo, brew tap kde-mac/kde https://invent.kde.org/packaging/homebrew-kde.git
3. brew edit okular, workaround now is to comment out or delete the line depends_on "chmlib" (won't compile on macos arm64 for now as of 2021-08-18), then save (if using vim you need to first press i to insert/type, when saving then <esc> then :wq then <enter>.
4. brew install okular, wait for stuff to compile and/or install
5. It may ask for keychain credentials (to sign the binaries? because of mac arm64 security policy https://eclecticlight.co/2021/01/26/when-you-dont-have-permission-to-run-an-app-on-an-m1-mac/)
6. $(brew --repo kde-mac/kde)/tools/do-caveats.sh
7. Now okular is in your $HOME/Applications/KDE folder, and will show up in Launchpad! You can view pdf, djvu, etc documents.

I’m probably going to make a nix derivation for it sometime. so I can install on mac too.

installs on macbook and works so far

But I cannot print PDF files...

I downgraded followings.

$ brew doctor

Then, I could install okular 23.08.2. But the print preview is too small and I cannot print PDF files...

Is there someone help me?
