What is a normal CPU temperature for a Mac?
What temperatures Apple silicon and Intel Macs run at, why high readings under load are normal, and the signs that heat is really a problem.
What is a normal CPU temperature for a Mac?
Low at idle and high under sustained load; chips are designed to run near their limits briefly and are protected by throttling. A high number during an export is expected.
When is Mac heat a problem?
When performance drops during ordinary work, fans stay loud at idle, the case is too hot to touch, or thermal pressure is not Nominal: check thermal pressure.
What makes a Mac run hotter than usual?
A stuck process at high CPU, background tasks after an update, blocked vents and a hot room. Mac hot when idle covers the first two.
