I am executing this on my M2 Air since codex has been causing overheating.

Will let you know how it goes

Thanks for trying it on your M2 Air. Yeah, it’s a bit odd that the issue hasn’t been fixed, but people have reported that this patch helps in practice. Looking forward to hearing how it works for you.

this isn't only affecting macbooks, I get massive CPU usage on every platform, even linux, it's just most visible with macbooks air because they overheat because of this, other platforms usually have weaker CPUs with better cooling so it's not so visible, still annoying though
