Os x boot sequence : what is launched at startup of your Mac can be easily discovered :
“System Preferences” -> “Users & Groups” -> “Login Items”
#1 MAC Boot sequence
busycrack$ ps aux | grep launchd
root 1 0.0 0.1…0:07.95 /sbin/launchd
| ~/Library/LaunchAgents | Per-user agents provided by the user |
| /Library/LaunchAgents | Per-user agents provided by the administrator |
| /Library/LaunchDaemons | System-wide daemons provided by the administrator |
| /System/Library/LaunchAgents | Per-user agents provided by Mac OS X |
| /System/Library/LaunchDaemons | System wide daemons provided by MAC OS X |
For example in my home directory I have:
busycrack$ ls -ltratotal 24-rw-r–r–@ 1 busycrack staff 806 Jul 11 20:59 com.google.keystone.agent.plist-rw-r–r– 1 busycrack staff 697 Jul 20 22:25 com.*****.XXXXX.YYYYYYY-1.0.plistdrwx——@ 55 busycrack staff 1870 Jul 28 18:06 ..-rw-r–r– 1 busycrack staff 606 Jul 28 18:40 de.metaquark.appfresh.plist
#a) list all with command “lauchctl list”
busycrack$ launchctl list…- 0 de.metaquark.appfresh581 – [0x0-0x4b04b].de.metaquark.appfresh- 0 com.apple.metadata.mdwrite…
Where :
| PID | Last Exit Status | Job Label |
| 581 | - | [0x0-0x4b04b].de.metaquark.appfres |
| - | 0 | de.metaquark.appfresh |
#b) get details : ”lauchctl list de.metaquark.appfresh”
busycrack$ launchctl list de.metaquark.appfresh{“Label” = “de.metaquark.appfresh”;“LimitLoadToSessionType” = “Aqua”;“OnDemand” = true;“LastExitStatus” = 0;“TimeOut” = 30;“ProgramArguments” = (“/Applications/AppFresh.app/Contents/Resources/AppFreshDaemon”;“/Applications/AppFresh.app”;);};
#c) list all which is not by apple : “launchctl list | grep -v com.apple”
busycrack$ launchctl list | grep -v com.applePID Status Label216 – com.MadCatz.SmartTechnology- 97 com.adobe.CS5ServiceManager- 0 com.google.keystone.user.agent…Note : try also “sudo launchctl bslist | grep -v apple”
#d) remove : “launchctl remove de.metaquark.appfresh”
#e) disable : “launchctl unload -w ~/Library/LaunchAgents/…”
How disable Deamon/Agent at startup?
launchctl unload -w ~/Library/LaunchAgents/com.google.keystone.agent.plist
less ~/Library/LaunchAgents/com.google.keystone.agent.plist<!DOCTYPE plist PUBLIC “-//Apple//DTD PLIST 1.0//EN” “http://www.apple.com/DTDs/PropertyList-1.0.dtd”>
<plist version=”1.0″>
