The actual worst part is that it is impossible to draw a meaningful conclusion from a problem report like this one:
> Mine also shines from the holes when closed. M1 Air. Noticed happens when browser is open and i closed the lid.
Yeah, it shines from the holes. Also develops a halo. Sometimes two. Maybe three, dunno. Sometimes the laptop can see stars.
Yes, it can be indeed an OS related problem as it is not bug free. Or, it could be a faulty laptop specimen, or – most likely – the user has installed something on their laptop that meddles with the sleep routine activation. For instance, OS X has a power nap feature that allows the OS to wake up briefly from the slumber, quickly do something (e.g. check mail, syncronise messages etc) and go back into slumbering again. Any application can register with the operating system to be awaken during a power nap.
And this is where the problem occurs. Users install tons of jackshite on their laptops, and that stuff tends to run a myriad of pre- and postinstallation scripts that crap all over the file system, the launch service database, and install user and system wide agents and all sorts of other unthinkable things. Including adding themselves into the power nap wakeup list without having a real need for it. At best, the app can drain the battery, and it usually does. At worst, the app bundles an system level extension that is buggy and crashes the system when invoked. But oftentimes, such nonsense does not yield its slot in the power nap run queue easily, which meddles with the laptop going back into the sleep and results in all sorts of bizarre problems.
Enterprise software is the worst offender. Nearly every. single. one. enterprise app installs (or runs) untold amounts of crap all over the file system, and nearly each app comes nowadays with its own software update daemon that is forcibly installed into the launchd database and runs 24x7, including at the power nap time. Is there a need to run a update daemon 24x7 to check for updates multiple times a day instead adding a crontab entry to wake it up once a day? No. Is there a need to install a «helper» daemon that does nothing but phones home non-stop sending undisclosed, non-consentual telemetry (likely PII too and more)? Absolutely no.
Microsoft Office is a prime example of such an invasive pest with Citrix Workspace being one of the worst offenders I have encountered in a while. Pick apart installation bundles for either and take a look at their respective pre- and postinstall scripts. Faeces that both slap onto a working OS install have to be thoroughly scrubbed off after, and they can only be scrubbed off with a hardened spatula. I really wish all downloadable app installs could be sandboxed by default and contained to their sandboxes without being able to ever break out of them. APFS supports COW snapshots, so perhaps the installer could create a sandbox and give each a private copy of system configuration files and databases that only the app could crap into into an oblivion without having an effect on a wider system installation.*
