@bjornregnell It is my belief the instructions for getting up and running on Mac are more cumbersome and thereby harmful for the learning experience than they have to be.

Apple har på grund av licensregler bestämt att inte längre inkludera senaste versionen terminalskalet bash i MacOS och har i stället gått över till zsh. Alla instruktioner i pgk och dod förutsätter bash. Följ instruktionerna om hur du får igång bash på MacOS här: https://www.howtogeek.com/444596/how-to-change-the-default-shell-to-bash-in-macos-catalina/ Det är bra om du installerar en nya version enligt instruktioner här, men det är inte strikt nödvändigt: https://www.shell-tips.com/mac/upgrade-bash/

This is true, but from my own anecdotal knowledge and experience, this does not matter what so ever, not for dod and not for pgk, asking or even giving a hint to students who, plenty of which are pretty new to the terminal, to change their default shell is more likely to be harmful for their learning experience than anything, it's also overloading students with information, which I personally don't believe makes any contribution towards the learning goals set out.

Installera OpenJDK för ditt system härifrån: https://adoptium.net/ Välj att ladda ner OpenJDK version 21 (LTS) HotSpot för ditt operativsystem. Dubbelklicka på filen som laddas ned för att starta installationen. Om du får en varning ska du köra ändå genom att klicka på "Mer information" eller liknande. Under installationen välj alla dessa åtgärder: Update PATH, Associate .jar, Set JAVA_HOME, JavaSoft registry key. Starta om din dator. Starta terminalfönster och kontrollera att javac --version ger rätt version. Om något krånglar: fråga någon som installerat JDK förr om hjälp.

This is not a very beginner friendly way of setting up Java. Homebrew is the clear winner, by every metric for getting setup. It provides a much simpler installation journey, setting up PATH's/os var's for the user, it manages updates for you automatically and it's much more of a hands-off approach for installing different development tools. With over 44.6k stars on Github, it is the defacto way of setting up CLI tools on macOS.

Installera Scala med tillhörande verktyg i MacOS

Homebrew is even able to help you setup scala correctly, with a simple one-liner.

thanks @trilleplay PR welcome for update on a well-tested and easier macos path. I'm not sure about homebrew vs sdkman - perhaps sdkman is easier for jvm versions etc and non-macos-specific

I guess we need to think about how bash relates to dod as that is the default there and bash is a mandatory part of dod. good to sync with @mnordahl
