I upgrade to sonoma 14.8.1 both my m2 pro mbp and i9 intel mbp 2019.
m2 pro mbp seems to be same and running smoothly without any issue.
at 14.7.x, i9 intel mbp works smoothly without high cpu usage,
so I upgrade it confidentially to 14.8 since it has security fix.
but after mbp intel get upgraded, I feel spotlight, xprotect are using much more cpu than before.
I disable Siri and spotlight, reduce motion and reduce transparency.
but all processes are still try to use more cpu and mbp intel is making stronger fan noise which makes me can't work using it.
at 14.7.x, they almost 0% cpu without any noise.
