Oracle engineers will stop maintaining the macOS/x64 port of Java as of JDK 27. The decision is part of a larger effort to streamline Java development. This change affects users of Apple's older x64-based Macs.
The move is formalized in JEP 541, which deprecates the macOS/x64 port for removal. Oracle's decision is driven by the need to focus on more widely used platforms. The macOS/x64 port has been maintained alongside other ports, including macOS/AArch64.
The deprecation of the macOS/x64 port marks the end of an era for older Macs. Many developers have relied on this port to run Java applications on their x64-based Macs. With Apple's transition to AArch64-based processors, the need for x64 support has diminished.
Mikael Vidstedt, the owner of JEP 541, led the effort to deprecate the macOS/x64 port. The change is expected to simplify Java development and maintenance.
The impact of this change will be felt by users who still rely on older x64-based Macs. Those who have upgraded to newer AArch64-based Macs will not be affected.
As Java continues to evolve, users of older Macs may need to find alternative solutions or upgrade their hardware. The Java community will likely adapt to this change.
What happens to existing Java applications on macOS/x64? They will continue to work until JDK 27 is released, after which support will be discontinued. Will Oracle provide support for other macOS ports? Yes, Oracle will continue to maintain the macOS/AArch64 port. Can developers still use Java on older Macs? Yes, but they may need to stick with older versions of Java or find alternative solutions.
