Once done, your other users won’t be able to remotely wake up your Mac to use its shared resources. On a desktop Mac, you can change this with a toggle System settings > Power saving > Wake up for network access is turned off.
Shared services cause macOS Ventura not sleeping problems
There may also be times when other people using shared services on your Mac are preventing it from going to sleep. An example would be when someone accesses a printer connected to your Mac.

- Go systems settings
- Click on it general in the sidebar

Check the firmware or reset the SMC
Oftentimes, too, software updates can fix problems with macOS Ventura suddenly waking up or not sleeping. Always make sure your Mac is running the latest versions of macOS and all installed applications. You can also use Safe Mode to determine if the problem is caused by software loading when your Mac turns on.
Finally, you may need to reset your Mac’s System Management Controller (SMC) to fix the problem. This is especially true if the problem may be related to power management. If you have an Apple Silicon Mac, you just need to restart the computer.
