Sudden macOS crash causing malfunctioning of the keyboard backlit
Without any obvious reason, the computer freezes and shortly after shuts itself down (with a short intensive fan noise). After restart, the keyboard is not any more backlit. The only help till now is the SMC reset procedure. This has happened many times in the last 6 months and is coming more often since the upgrade to Monterey.
Has anybody got a similar problem and/or can point me to the possible solution?
