I have tried 'ulimit -c unlimited' and couple of other things mentioned in various forums. I have checked that /cores folder has write permissions. Still I couldn't manage to generate the core dumps for the crash on macOS bigsur 11.5.2. @eskimo Can you please list the steps required to enable the core dump on macOS bigsur 11.5.2 ? more info from my machine kern.corefile: /cores/core.%P kern.coredump: 1 kern.sugid_coredump: 0 machdep.cpu.thermal.core_power_limits: 1 machdep.cpu.core_count: 8 machdep.cpu.cores_per_package: 8 launchctl limit cpu unlimited unlimited filesize unlimited unlimited data unlimited unlimited stack 8388608 67104768 core 0 unlimited rss unlimited unlimited memlock unlimited unlimited maxproc 5568 8352 drwxrwxrwx 2 root staff 64B Oct 20 19:21 cores
