Ensure install.log Is Retained for 365 or More Days and No Maximum Size

MediaNivel 1Automatizadamacos

Descripción

macOS writes information pertaining to system-related events to the file /var/log/install.log and has a configurable retention policy for this file. The default logging setting limits the file size of the logs and the maximum size for all logs. The default allows for an errant application to fill the log files and does not enforce sufficient log retention. Audit: Requires ttl >= 365 and no all_max= setting in /etc/asl/com.apple.install.
