Your Mac sits on the Apple Intelligence download screen for hours and the progress bar refuses to move, and the culprit is almost always one toggle: Low Power Mode. When that setting is on, macOS deliberately suspends background tasks to save battery, and the multi-gigabyte Apple Intelligence model download is exactly the kind of background task it pauses.

Quick Answer

Turn off Low Power Mode under System Settings > Battery, keep the Mac plugged in and on Wi-Fi, and the stalled download resumes. The full model download can run 4 to 5 hours, so leave the lid open and let it finish in the background.

Why Low Power Mode stalls the download

Apple Intelligence models are not bundled with the operating system. After you enable the feature, macOS fetches them in the background, and that download is large enough to take several hours on a typical home connection. Low Power Mode is built to extend battery life by throttling exactly these non-urgent background jobs. So the moment the setting kicks in, the download queues quietly with no error and no movement, which reads as a frozen stall even though nothing is broken.

This is also why the download often appears to stop on battery and resume on power. Many Macs are set to enable Low Power Mode automatically when running on battery, so unplugging silently pauses the fetch.

The fix, step by step

  1. Open System Settings and go to Battery.
  2. Set Low Power Mode to Never. If you see separate toggles for "On Battery" and "On Power", switch both off for now.
  3. Plug the Mac into power so it is not relying on the battery.
  4. Confirm you are on a stable Wi-Fi network and leave the lid open.
  5. Give it time. The download can take 4 to 5 hours, and progress may sit at one percentage for a while before jumping.

Once the models are fully downloaded, you can turn Low Power Mode back on. It only interferes during the initial fetch.

Other things that can hold it up

If the download still will not move with Low Power Mode off, the usual secondary causes are a sleeping Mac, a weak connection, or simply server demand right after a major macOS release. Stop the Mac from sleeping while plugged in, switch to a wired or stronger Wi-Fi signal if you can, and try again later if Apple's servers are clearly under load. A restart sometimes nudges a genuinely stuck download back to life.

Frequently Asked Questions

How long should the Apple Intelligence download take?

Plan for 4 to 5 hours on a typical connection. The progress bar can sit on one number for a while and then jump, so a paused-looking download is not necessarily stuck.

Will turning off Low Power Mode hurt my battery?

Only marginally, and only while the download runs. Once the models are installed you can switch Low Power Mode back on with no effect on Apple Intelligence.

Why does it pause when I unplug the charger?

Many Macs auto-enable Low Power Mode on battery, which suspends the background download. Keep the Mac plugged in until the model fetch completes.

It is still stuck after disabling Low Power Mode. Now what?

Stop the Mac from sleeping, confirm a strong Wi-Fi signal, restart, and try again later if Apple's servers are busy after a recent update. These three steps clear most remaining stalls.
