An issue introduced by macOS 14.4, which causes Java process to terminate unexpectedly, is affecting all Java versions from Java 8 to the early access builds of JDK 22. There is no workaround available, and since there is no easy way to revert a macOS update, affected users might be unable to return to a stable configuration unless they have a complete backup of their systems prior to the OS update.
We will not be able to correct for this issue within AIJ, so please do not update to MacOS 14.4 if you depend on using AstroImageJ and use Apple silicon processors (M1, M2, and M3), until a java fix is released.
