Mac tricks – command line

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

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

To re-enable Bonjour:

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

Disable Creation of Metadata Files on Network Volumes

defaults write com.apple.desktopservices DSDontWriteNetworkStores -bool true

Re-enable:

defaults write com.apple.desktopservices DSDontWriteUSBStores -bool true

Save to Disk by Default and not on Cloud products

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:

sudo pmset hibernatemode 25

Banana Pi Pro – WLAN configuration

Add ‘ap6210‘ to /etc/modules to enable WiFi, and use modprobe ap6210 to force load the module.

Check dmesg to see if all has been loaded correctly. If not, reboot and check again.

dmesg|grep WLAN

Install the required packages:

apt-get install wireless-tools iw wpasupplicant

Modify /etc/network/interfaces

# Dinamic IP:
auto wlan0
allow-hotplug wlan0
iface wlan0 inet dhcp
wpa-ap-scan 1
wpa-scan-ssid 1
wpa-ssid "WIFI_NETWORK_NAME"
wpa-psk "WLAN-KEY"

# Static IP:
auto wlan0
allow-hotplug wlan0
iface wlan0 inet static
address 192.168.xx.yy
netmask 255.255.255.0
gateway 192.168.0.1
wpa-ap-scan 1
wpa-scan-ssid 1
wpa-ssid "WIFI_NETWORK_NAME"
wpa-psk "WLAN-KEY"

Bring the interface up:

ifconfig wlan0 up
