How can I direct messages from mac console.app to a log file?
I'm trying to complete a bash script to capture if an external webcam is active in a video conference session. Some users will switch the camera to the built-in MAC camera. When this happens I want to trigger a set of events.
Things tried: reviewed the console.app to look for patterns on when the switch occurs in a user test & discovered messages indicating when the facetime camera changes state. I found this
I thought I could simply grep these message from the console.app but it seems to be easier said than done. I thought i could find the msgs in one of the console report files but When I look at the various reports on the console, i'm not finding a report that contains the messages above. How can I direct messages from console.app to a log file versus manually copying and pasting the info from the console?or point me to a direction? Am I missing something?

What is the best practice to allow a 3rd party health monitoring app to read the messages file. Since messages is a system file and is owned by root the app cannot read the file. I don't want to run the app as root so how should I allow the app to read the file. The read function is actually built... (2 Replies)

mac_seeotheruids
MAC_SEEOTHERUIDS(4) BSD Kernel Interfaces Manual MAC_SEEOTHERUIDS(4)NAME
mac_seeotheruids -- simple policy controlling whether users see other users
SYNOPSIS
To compile the policy into your kernel, place the following lines in your kernel configuration file:
options MAC
options MAC_SEEOTHERUIDS
Alternately, to load the module at boot time, place the following line in your kernel configuration file:
options MAC
and in loader.conf(5):
mac_seeotheruids_load="YES"
DESCRIPTION
The mac_seeotheruids policy module, when enabled, denies users to see processes or sockets owned by other users.
To enable mac_seeotheruids, set the sysctl OID security.mac.seeotheruids.enabled to 1. To permit superuser awareness of other credentials by
virtue of privilege, set the sysctl OID security.mac.seeotheruids.suser_privileged to 1.
To allow users to see processes and sockets owned by the same primary group, set the sysctl OID
security.mac.seeotheruids.primarygroup_enabled to 1.
To allow processes with a specific group ID to be exempt from the policy, set the sysctl OID security.mac.seeotheruids.specificgid_enabled to
1, and security.mac.seeotheruids.specificgid to the group ID to be exempted.
Label Format
No labels are defined for mac_seeotheruids.

mac(9)HISTORY
The mac_seeotheruids policy module first appeared in FreeBSD 5.0 and was developed by the TrustedBSD Project.

BUGS
See mac(9) concerning appropriateness for production use. The TrustedBSD MAC Framework is considered experimental in FreeBSD.
While the MAC Framework design is intended to support the containment of the root user, not all attack channels are currently protected by
entry point checks. As such, MAC Framework policies should not be relied on, in isolation, to protect against a malicious privileged user.
