I ran through the following "How to protect Mac computers from cold boot attacks guide": https://sunknudsen.com/privacy-guides/how-to-protect-mac-computers-from-cold-boot-attacks
It appears to be working as described, but I have noticed what appears to be a side effect after "waking" my Mac two or more times. I start to have glitchy audio/video playback issues regardless of the tool I try to use (e.g.,
mpv
, Quicktime, a browser, etc). When this starts to happen, the only thing that seems to resolve it is to perform a full system restart.(I know "glitchy" is a rather nondescript way to describe how audio skips and video playback can jump ahead to seemly random spots quickly until the video is done. Suffice it to say, whatever video it is, it is unwatchable.)
Has anyone seen or experienced this type of issue after applying the
pmset
commands? And if so, do you have any resolution besides a full system restart? If there's a CLI command I can run to reset something, I'm fine with this, but I haven't found anything yet that seems to work. (e.g., I found some posts oncoreaudiod
, but the proposed fixes for that didn't seem to do anything for me here.)I'm running the latest macOS Ventura version at the moment.
