How does macOS manage virtual cores on Apple Silicon?
Summary: macOS manages virtual cores on Apple silicon by assigning Quality of Service (QoS) to apps, which is considered during scheduling. With the introduction of Game Mode in Sonoma, E (Efficiency) cores can be reserved for games. When running a macOS virtual machine (VM) with a set number of virtual cores, macOS Sonoma handles the situation by following its normal rules for thread scheduling and dispatch. VMs lack energy efficiency and background performance advantages of macOS running on an Apple silicon host.
