Apple tricks

Time machine

  • enable network volumes:
defaults write TMShowUnsupportedNetworkVolumes 1
  • create file on shared directory
  • avaho notification for bonjour:

write a file named afpd.service in: /etc/avahi/services

<?xml version="1.0" standalone='no'?><!--*-nxml-*-->
<!DOCTYPE service-group SYSTEM "avahi-service.dtd">
<!-- Customize this to get a different name for your server in the Finder. -->
<name replace-wildcards="yes">%h server</name>
<!-- Customize this to get a different icon in the Finder. -->
<!-- <txt-record>model=RackMac</txt-record> -->


  • icons for bonjour, check in this file (better with xcode)
strings /System/Library/CoreServices/CoreTypes.bundle/Contents/Info.plist|less


  • list AFP hosts in network
dns-sd -B _afpovertcp._tcp .
  • list SSH available hosts
dns-sd -B _ssh._tcp .


  • ssh to a bonjour host
mac1:~ user$ dns-sd -B _ssh._tcp .
Browsing for _ssh._tcp
Timestamp     A/R Flags if Domain                    Service Type              Instance Name
10:21:16.447  Add     2  4 local.                    _ssh._tcp.                xsysadmin
10:21:16.452  Add     2  4 local.                    _ssh._tcp.                v2_ video edit
10:21:16.458  Add     2  4 local.                    _ssh._tcp.                x’s Mac Pro
  • remove spaces with '-' and add .local at the end
mac1:~ user$ ssh v2-video-edit.local


  1. create /etc/rsyncd.conf (file 1)
  2. create /etc/rsyncd.secrets (file 2)
  3. create /Library/LaunchDaemons/rsyncd.plist
  4. reboot
  • file 1 (rsyncd.conf)
path = /Users
comment = User files
auth users = backuppc
secrets file = /etc/rsyncd.secrets
hosts allow =     CHANGE THIS!
strict modes = false
read only = true
list = false
  • file 2 (rsyncd.secrets)
backuppc:chosenpassword         CHANGE THIS!
  • file 3 (rsyncd.plist)
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN" "">
<plist version="1.0">


  • scutil is a sort of console for configuration and status of the system (just found out this command, I'll do further documentation)

network behavior

  • prevent creating files (like .DS_store apple double atc.) in network mounted shares.
defaults write DSDontWriteNetworkStores true

name servers

  • Purge dns cache ( or empty dns history, clear dns cache)
dscacheutil -flushcache
lookupd -flushcache

un-hide Library folder

chflags nohidden ~/Library

  • show disk partitions
 sudo diskutil list

NFS on Mac

  • become root
sudo -s
  • example:
mkdir /mountpoint
mount_nfs -o resvport /mountpoint
