Supported Platforms

4.0 beta 4 includes several updates to how different operating systems and hardware are handled. This allows us to add Apple Silicon (M1) support, and also better handles other devices like the Raspberry Pi.

The final decision is that a “variant” should consist of the OS name (windows, macos, or linux) followed by a the naming from the os.arch value returned by System.getProperty(). Because those names can vary across JDK implementations, we'll be using the name used by the JDK included with the Processing download, which is currently from Adoptium.

This new {os}-{arch} helps drastically simplify the code inside the PDE, and also gets us out of the business of deciding how to rename each platform. While the naming is sometimes awkward (i.e. macos-x86_64), the alternatives are inelegant as well, so we'll err on the side of simplicity by inheriting how the platform handles naming.

As a result of these changes, the subfolders used to identify native libraries for each platform are different. Old libraries will still work, but you're strongly encouraged to use these new names for clarity.

Hardware/OS	os.arch	bits	4.0 library folder name	old library folder name	download suffix
Apple Silicon (i.e. M1)	aarch64	64	macos-aarch64	—	macos-aarch64
Apple Intel	x86_64	64	macos-x86_64	macosx	macos-x64
Windows 10 (64-bit)	amd64	64	windows-amd64	windows64	windows-x64
Linux (Ubuntu 64-bit)	amd64	64	linux-amd64	linux64	linux-x64
Raspberry Pi OS	arm	32	linux-arm	linux-armv6hf	linux-arm32
Raspberry Pi OS (64-bit beta)	aarch64	64	linux-aarch64	linux-arm64	linux-arm64

(The “bits” column is equivalent to sun.arch.data.model)

You can also view the Supported Platforms from 3.x, though half that information will be out of date.
