Prevent Mac from Sleeping on Sonoma: How to Turn off Sleep Mode on MacOS 14?

Keep Your Mac Awake: Preventing Sleep Mode in macOS Sonoma

Imagine this: you're engrossed in a task on your Sonoma-powered Mac, step away briefly, and return to a blank screen. This sleep mode interruption can be frustrating. Fortunately, disabling sleep mode is easy and can significantly boost productivity. This guide shows you how to keep your Mac active when you need it.

Understanding macOS Sonoma's Sleep Mode

Sleep mode in macOS Sonoma conserves power and extends battery life by dimming the display and pausing background processes. While your Mac isn't completely off, power consumption is minimal. This is great for short breaks, but disruptive during downloads, uploads, or video conferencing.

Why Disable Sleep Mode?

Consider these scenarios where sleep mode is more trouble than it's worth:

• Large file transfers: Downloads and uploads can fail if interrupted by sleep mode.
• Media processing: High-definition video or image processing requires uninterrupted operation to prevent data corruption.
• Video conferencing: Sleep mode can disconnect you from important meetings.
• Frequent short breaks: Constantly waking your Mac disrupts workflow.

Preventing Sleep Mode: Four Methods

Here are several ways to prevent your MacBook, iMac, or Mac mini from sleeping in macOS Sonoma:

1. Adjust Power Saving Settings:

   1. Access System Settings from the Apple menu.
   2. Navigate to Battery > Options.
   3. Enable Prevent automatic sleeping when the display is off.

   

2. Configure Lock Screen Settings:

   1. Open System Settings.
   2. Select Lock Screen.
   3. Set Start Screen Saver when inactive and Turn display off when inactive to Never.

   

3. Use the Terminal:

   1. Open Terminal (use Spotlight search).
   2. Enter caffeinate -d and press Enter to keep your Mac awake indefinitely (close the Terminal window to re-enable sleep). Alternatively, use caffeinate -t [seconds] (e.g., caffeinate -t 3600 for one hour).

   

4. Employ a Third-Party App (Amphetamine):

   1. Download and install Amphetamine from the App Store.
   2. Click the Amphetamine icon and select Indefinitely.

   

Maintaining Peak Mac Performance

While these methods prevent sleep mode, consider using a tool like MacKeeper's Find & Fix for overall system optimization, including improved startup times and app updates. This holistic approach ensures your Mac runs smoothly, regardless of your sleep mode settings.
