You might have read that Microsoft’s upcoming Windows 11 requires a Trusted Platform Module (TPM). More recent AMD CPUs support Firmware TPM (fTPM) which implements TPM in software on the CPU instead of requiring a dedicated (discrete) chip. This is how I enabled fTPM.
Last month, one morning, my MacBook (still running Catalina) started behaving strangely - though I was not running anything, it was sluggish as the CPU was too busy and the fans were on high. I traced it to the iOS Simulator service that comes with XCode.
