Big Sur - Disable Power Nap

Power Nap allows your Mac to perform actions while a Mac is asleep. This can interfere with USB power and may cause devices to stop functioning until a reboot and must therefore be disabled on all applicable systems.

The following Macs support Power Nap:

* MacBook (Early 2015 and later)
* MacBook Air (Late 2010 and later)
* MacBook Pro (all models with Retina display)
* Mac mini (Late 2012 and later)
* iMac (Late 2012 and later)
* Mac Pro (Late 2013 and later)

Solution
