Script of actions to run whenever a Mac wakes up from sleep
|
|
|
|
Currently this script just flushes the DNS cache to fix Chrome hitting ERR_NOT_FOUND errors when waking up on a VPN
|
|
|
|
To set this up, edit the path to this script in the plist xml file and then load it:
|
|
|
|
cp -fv $srcdir/com.harisekhon.wakeup_script.plist ~/Library/LaunchAgents/
|
|
launchctl load $srcdir/com.harisekhon.wakeup_script.plist
|
|
