The reports rounded up by MacRumors mention multiple Intel Mac models, ranging from the 2015 model year all the way up to 2020, but don't mention Apple Silicon models-this makes some sense, since they update a bit differently than Intel Macs and may not be susceptible to the same problems. MacRumors has rounded up a representative swath of complaints from the Apple Support Communities forums and Twitter, mostly describing the same symptoms: unresponsive Macs that can't be revived using the typical SMC and NVRAM diagnostic catch-alls. Anecdotal reports from over the weekend indicate that the macOS Monterey update may be bricking some Macs during installation, leaving the machines unresponsive.
