I have an M1 (2020 version) and an M2 (2022 version), I've updated the m2 (to Sonoma) first and the m1 the next day. It works just fine but charging was intermittent. The day after, both Macs stopped charging totally.
I've tried all possible solutions from the internet and Apple's support chat but nothing worked.
I've tried 4 chargers in total and my chargers would work on my brother's Macs which are still in Ventura. My chargers which would work on my Macs would work perfectly fine on my brother's Macs (Ventura).
I do not see any other threads/forums online of people having this issue so I wanted to check here if anybody else has the same issue as this?
P.S. I've sent both Macs to an authorized Apple service center for diagnostics but I'm wondering how this could happen since both Macs would work fine before I've upgraded. The issues started to appear only after the upgrade.
