1. The patch is required, atleast on intel macs, as without writing GPU and CPU
states to smc, the system gives PROCHOT signal under small load
, and heats up a lot.
2. the smc dosent expose keys of nature that can physically damage the system
it only exposes power/volt data, and the most you can poke is reboot
keys and gpu/cpu p-states.
3. If a person is randomly touching keys, Its their problem and not ours.
4. There are a lot of things that can mess the system way more and permanently
than smc (undervolting for example), but they are not safe guarded, why
should this be then?
