Comment | I don't know any business in particular so I have no idea if my recommendation is a good one but if you walked past the applestore before lockdown, there's a guy usually holding a sign for simplyfixit.
However, given you said it occurred after an update... I googled it and it seems to be a common problem due to a software incompatibility. If that's true, then a hardware solution won't solve it for you. The advice I saw from a few threads was to [reset the SMC](https://support.apple.com/en-us/HT201295) and [NVRAM](https://support.apple.com/en-us/HT204063). |
