High Power Mode on Mac: supported models and use

Which Macs support High Power Mode

The table reproduces the model groups in Apple's current Power Modes article, checked on 30 October 2026. These are Apple's groupings, rather than an expanded list inferred from chip names.

Identify your Mac with Apple menu › About This Mac; the model-identification guide helps if several generations share the same name. Read the full chip name, including Pro or Max where present.

Apple's list doesn't include a base M6 MacBook Pro, a MacBook Air or a MacBook Neo, so this guide doesn't either. If your exact model is outside the published groups, check its own documentation and available settings rather than trying to force a hidden mode.

Turn on High Power Mode for the right power source

For supported laptops on macOS 15 Sequoia, macOS 26 Tahoe and macOS 27, the route is System Settings › Battery › Energy Mode. Desktop Macs use System Settings › Energy. Apple's Battery settings guide distinguishes Low Power, Automatic and High Power.

1. Note the current mode so you can return to it after the comparison.
2. Under Energy Mode, choose High Power for On power adapter or On battery, as appropriate. The two sources keep separate choices on a laptop.
3. Use the battery or lightning-bolt menu to check the active mode. Return to Automatic through the same setting when you want the normal balance.

Apple also documents a Control Center shortcut from macOS 15.1 onward. The full Settings route is useful when you want to verify both power-source choices instead of changing only the situation you happen to be in.

A laptop can therefore be set to High Power on its adapter while retaining another choice when unplugged. Before comparing two runs, check which source is actually in use; otherwise an unplugged cable can change both the available input and the selected mode.

What High Power Mode changes

Apple describes extra fan speed and cooling capacity, which can help very intensive graphics work maintain performance. Its examples include demanding video and 3D workflows. Lighter apps and short tasks may not finish any sooner.

The Battery settings documentation describes High Power as increasing energy usage for sustained work. If you are away from a charger and care most about runtime, compare that priority with Low Power Mode instead.

Fan noise is a tradeoff you can assess directly. More audible cooling during a long export is not, by itself, evidence that the mode is malfunctioning. Conversely, hearing the fans does not prove that an export is faster. Judge the result you needed, such as completed output or useful playback, alongside the noise.

Compare the job you actually do

Use a repeatable task in your own app, with the same project and output settings. Save work first. These steps are a suggested comparison, not a benchmark we performed or a forecast of a particular speed gain.

1. Choose an outcome you can compare: time to finish the same export, or whether the same demanding playback section runs acceptably.
2. Keep the power adapter, connected displays, app version and project settings unchanged. Let optional downloads and other jobs finish.
3. Run in Automatic, record the outcome and note distracting fan noise. Switch to High Power and repeat the same job.
4. Repeat if a result was close or interrupted. Keep the setting that helps your work enough to justify its costs.

Do not compare the first run of a freshly opened project with a later cached run and assign every improvement to the mode. If a second attempt is quicker in either mode, preparation or caching may be part of the difference. Likewise, an unrelated cloud upload, update or render can change the comparison.

For light typing, a network-limited download or waiting on a remote service, first establish what you are waiting for. A performance mode cannot make a slow server return a response sooner. Use the slow-Mac diagnosis when the bottleneck is unclear.

Check the adapter and cooling before blaming the mode

Apple recommends a 96 W adapter for using High Power Mode while charging a 14-inch MacBook Pro with M4 Pro or M5 Pro. That recommendation is specific; it is not a universal adapter requirement for every Mac in the table.

If a battery falls during the comparison, keep that observation separate from task speed. The plugged-in battery-drain guide checks input against the workload, and the charger reference helps you choose an adapter and cable. A mode change is not a way to increase a dock's power output.

Keep the Mac on a stable, ventilated surface. If it runs unusually hot during light work, follow the overheating guide rather than treating a higher fan mode as a repair. A missing High Power option is also different from a cooling fault: check model support first.

How Tend helps

Tend's free app view shows estimated per-app watts and 24 hours of energy history, helping you see which work coincides with increased demand. Pro adds detailed temperature sensors, fan readings and longer history. Tend helps you look after your Mac; its optional companion shows how it's doing. To choose the power mode, use macOS's own settings.
