Mac tricks - command line

Strange wake up of your Mac To disable Bonjour (mDNSResponder - NoMulticastAdvertisements):

sh
sudo defaults write /System/Library/LaunchDaemons/com.apple.mDNSResponder ProgramArguments -array-add "-NoMulticastAdvertisements"

To re-enable Bonjour:

sh
sudo defaults write /System/Library/LaunchDaemons/com.apple.mDNSResponder ProgramArguments -array "/usr/sbin/mDNSResponder" "-launchd"

Disable Creation of Metadata Files on Network Volumes

sh
defaults write com.apple.desktopservices DSDontWriteNetworkStores -bool true

Re-enable:

sh
defaults write com.apple.desktopservices DSDontWriteUSBStores -bool true

Save to Disk by Default and not on Cloud products

sh
defaults write NSGlobalDomain NSDocumentSaveNewDocumentsToCloud -bool false

Power off memory during standy hibernatemode supports values of 0, 3, or 25. Whether or not a hiberna- tion image gets written is also dependent on the values of standby and autopoweroff For example, on desktops that support standby a hibernation image will be written after the specified standbydelay time. To disable hibernation images completely, ensure hibernatemode standby and autopoweroff are all set to 0.

hibernatemode = 0 by default on desktops. The system will not back memory up to persistent storage. The system must wake from the contents of mem- ory; the system will lose context on power loss. This is, historically, plain old sleep. hibernatemode = 3 by default on portables. The system will store a copy of memory to persistent storage (the disk), and will power memory during sleep. The system will wake from memory, unless a power loss forces it to restore from hibernate image. hibernatemode = 25 is only settable via pmset. The system will store a copy of memory to persistent storage (the disk), and will remove power to memory. The system will restore from disk image. If you want "hiberna- tion" - slower sleeps, slower wakes, and better battery life, you should use this setting.

It is suggested to power off memory at stand-by with the following command:

sh
sudo pmset hibernatemode 25
