Some Mac systems, including recent MacBook Pros, aren’t designed to adequately dissipate the heat they generate when under heavy load, so macOS drastically slows down the system in order to generate less heat. This is called thermal throttling. This behavior may affect the performance of your Vuo compositions.
You can monitor macOS’s thermal throttling by opening
Terminal.app and running this command:
pmset -g thermlog
. It will automatically
update when the status changes. When the
CPU_Speed_Limit
value is less than 100,
thermal throttling is active.
To mitigate this, consider trying some of the following options:
Reset your Mac’s SMC to recalibrate its thermal management profile, which may change when macOS decides to apply thermal throttling.
Improve your Mac’s heat dissipation:
Ensure your Mac is in a cool room and placed on a cool surface out of direct sunlight.
Ensure your Mac’s air inlets and egresses are unobstructed.
Hire a qualified technician to disassemble your Mac and clean the dust from its fans.
Use an external fan to draw hot air away from your Mac.
Install 3rd-party software to increase your Mac’s internal fan speeds.
Reduce the CPU and GPU usage of your composition:
Reduce the image and mesh resolutions.
Reduce the framerate.
Reduce the number or quality of image filters.
