Use High Power Mode for more performance on your Mac

Why it happens

High Power Mode lets the fans run harder so the chip can keep working at full speed for longer. That helps with long renders, exports and heavy games. It's offered on some MacBook Pro models with Pro or Max chips and on some desktop Macs.

How to fix it

1. Open the Apple menu, choose System Settings and click Battery.

2. Find Energy Mode. If it isn't there, your Mac doesn't offer High Power Mode.

3. Choose High Power for when your Mac is on the power adapter. If your Mac offers it for battery too, you can pick it there, but the battery will drain faster.

4. On a desktop Mac, such as a Mac mini, click Energy instead of Battery and choose High Power from Energy Mode.

5. Expect the fans to get louder when the Mac is busy. That's normal in High Power Mode.

Still not fixed?

1. No Energy Mode at all? Install the latest update in General > Software Update. If it's still missing, your model doesn't support it.

2. Not feeling faster? High Power Mode helps with long, heavy jobs. Web browsing and short tasks feel the same. To see what's working the chip hardest, open Activity Monitor and click CPU.

3. Want longer battery life instead? Choose Low Power from the same Energy Mode menu.

4. If the fans roar all the time, even when the Mac is idle, or it shuts down under heavy work, contact Apple Support or an Apple Authorized Service Provider. That can be a cooling or hardware problem.
