A range of features on Apple Inc. computers let you enhance network performance while also reducing energy consumption. On occasion, though, you'll need to keep a Mac service running even while it's in sleep mode.
In addition to the Power Nap feature that updates data on your Mac while the Mac is sleeping, wake for network access is another option used to customize the sleep settings on your Mac. Let's dive into more!
What is wake for network access on Mac
Apple allows you to share Mac resources while it's in sleep with the feature wake for network access, also known as wake on LAN. With this feature turned on, it wakes your Mac even while it's sleeping to provide you/others access to shared resources like shared printers or music playlists.
Mac sleep mode stops hard disk and background processes to conserve energy and prevent wear. But sometimes, incoming network access on your Mac needs it to be awake such as remotely logging into the computer from another location, or having outside tech support to handle system maintenance, etc. Taking that into consideration, wake for WiFi network access/wake for network access comes into being, available on Mac OS X and higher.

Wake for network access not working on Mac? Fixed!
I have an 27" iMac and I also have an M1 Macbook Air. I have "Wake For Network Access" checked on both computers, however if the iMac is in sleep mode, it does not appear in the Finder sidebar on the Macbook Air. I have to physically wake the iMac, and then it will appear in the sidebar of the Macbook Air, which defeats the purpose of the "Wake For Network Access" feature. Any advice? Thanks.
This is a seemingly common issue that wake for network access not working on Mac. Although the feature has already been enabled, the target Mac can not be accessed via the network while it is in sleep mode. To get this problem solved, you can try the methods below:
- Disable and re-enable wake for network access on Macs.
- Change a network such as WiFi and Ethernet for the feature.
- Restart your Mac.
- Stop Mac from sleeping to be always accessed.
