2nd log file is missing data
general observations - old (6 generations), low-end ultra-low power CPU for real-time video encoding... with a bunch of audio filters... doable, but just as driving blindfolded is a bad idea, you need to be doing real-time hardware resource utilization monitoring (CPU, GPU, network, disk I/O, etc). The OBS log does NOT indicate what else is going on with the Operating System and other apps/processes.
it is your responsibility to keep an eye on/know what else is going on at the OS level.
Your comment of first time... would imply your setup is sufficient for your OBS settings... and something changed... if your Mac now over-whelmed, then most likely either:
- a background process running you weren't expecting/aware of (like a disk security scan?) and that impacted system performance
- an OS update changed something that is impacting hardware resource utilization
- Something you were running is now consuming more resources (CPU, GPU, disk i/o, etc) and that is impacting you
- you changed an OBS setting, and that is now consuming more resources (ex 1 of the audio filters)
