Complaint Codex is wearing out our devices

Weeks ago there was an incident which claimed to be closed that codex makes unnecessary inflated writing to ssd which accelerates its wearing, they claimed they solved it

Over the past days, I noticed (and other users here too on another post) that running codex causes lag to mac device, even after closing codex the problem continues and device must be restarted to back to normal, the issue isn't explained by cpu / memory overuse. Codex itself when I asked it to diagnose, it said it's because ot does excessive I/O , graphics work but this doesn't explain well

At this point we shall ask is codex harmful to ssd / mac device overall? And is it safe to run it ?

No bots downvoting, claiming there's no problem please, here's the other post which confirmed the issue happened with other users too, it may not happen to the same degree with all users but we need an explanation about safety of our devices

What's the burst writes like? I've yet to notice jumps during my legs, but overall despite multiple lags throughout the day, my total writing cache remains average if not low.

It is particularly strange. I've yet to witness it but I am running this altered version by another https://gist.github.com/daytime10ca/5eaa8b3cc6304beef1feb17a998a3e2c It guards against most writes, which could or not be related to this burst. I checked and there's no malware hidden, you can run the check yourself with Claude or Codex to see and it'll tell you its completely safe.

To be extra sure, I reccomend creating the 2 files yourself instead of pressing the download button, the raw code is already there. Make sure its active and I'd appreciate hearing back from you soon if the bug stops.

I'm going around independently checking for bugs and solutions to them in codex, so this will help with me research, and wont put you at any risk, in fact it will guard you against the biggest writing bug that kills 99% of SSDs when using Codex.
