If you need to have openjdk first in your PATH, run:Įcho 'export PATH='/opt/homebrew/opt/openjdk/bin:$PATH'' > ~/.zshrcįor compilers to find openjdk you may need to set:Įxport CPPFLAGS='-I/opt/homebrew/opt/openjdk/include'

Since I’m on an Apple M1, I’ll go ahead and download the macOS/AArch64 file. You can also check out the Apple Support article “Mac computers with Apple silicon” for additional details.

To determine this, choose the Apple menu -> About this Mac and then look at the Chip section:

Since Apple moved using their own ARM chips (“Apple Silicon”) starting with the M1 series, you’ll have to choose between “macOS / AArch64” (Apple M1 and above) and “macOS / 圆4” (older Intel chips). For the demo, we’ll just go with the latest version (OpenJDK 19 as of Nov 2022) and you’ll be taken to a page with links to platform specific downloads.
