QuietCPU is getting ready for Mac
CPU monitoring, Mira and Luna are free
A few things to know
Is the app free?
CPU monitoring and the two basic companions, Mira and Luna, are free. Extra character packs are optional one-time purchases. No subscription.
Why can CPU usage go above 100%?
Each CPU core can contribute up to 100%. Work spread across several cores can add up to more than 100%.
Does it close apps automatically?
By default, QuietCPU asks before closing a process. Automatic closing only applies to rules you explicitly enable. System processes and active apps are protected.
Can I change the size or start it at login?
Yes. App settings let you choose the character’s size, the menu bar percentage display and whether QuietCPU starts when you log in.
