If you’re experiencing trouble with your Mac not entering deep sleep mode, this guide provides a practical solution to address the issue. The latest macOS Sonoma, while introducing several exciting features and performance enhancements, may still have some rough edges, one of which is related to its sleep cycle.
Previously, users could observe spaces between the green bars in the Battery Chart, indicating that the system entered sleep mode during inactive periods, at least up until Ventura. However, with the latest Sonoma build, users have reported that their Macs aren’t going into deep sleep when the laptop lid is closed.
This issue can lead to a slightly faster battery drain, making it crucial to find a resolution promptly. Let’s dive into the steps to rectify this problem without delay.
Solution 1: Disabling tcpkeepalive
- Navigate to Launchpad > Others > Terminal.
- Enter the following command: sudo pmset -b tcpkeepalive 0
- Press Enter to execute the command.
- Verify if macOS Sonoma now enters Deep Sleep as expected.
Solution 2: Disabling Power Nap
- Go to System Settings > Battery > Options.
- Click the pop-up menu next to “Enable Power Nap.”
- Select “Never” from the drop-down menu.
- If using an Intel iMac, access it from Energy Saver.
- Check if disabling Power Nap allows your Mac running Sonoma to go into Deep Sleep.
