Furthermore, the technical architecture of the installation has shifted significantly with the advent of Apple Silicon (M1, M2, and M3 chips). For nearly fifteen years, Macs ran on Intel x86 architecture, meaning a single "universal" Java installer was the norm. With the shift to ARM-based Apple Silicon, users must now ensure they are installing the correct architecture-specific version of the runtime. While Apple’s Rosetta 2 translation software allows Intel-based Java applications to run on Apple Silicon, performance is significantly better when a native ARM64 Java runtime is installed. The installation directory has also moved; while legacy versions may linger in /Library/Java/JavaVirtualMachines , managing multiple versions often requires using command-line tools or package managers like Homebrew to ensure the correct runtime is active. java runtime install mac

For the average end-user, this distinction is often blurred; they simply want the "Java" that makes their .jar file run. ProgrammingKnowledge 59s Fix "Unable to Locate a Java
