Hallo, I created an AppleScript for my Synology NAS and saved it as NAS.app. This starts the server and mounts the network drives. If the script is run again when the server is already online, it can shut down the Mac and server. That works very well. But the next time I start the Mac, this app is immediately active again and may have to be closed manually. I'm now looking for a way to prevent this. How can I kill the app after issuing the shutdown command? Here is the part with the Mac shutdown code. set ProcNm_ to name of every application process whose visible is true end tell repeat with i_ from 1 to count items of ProcNm_ set TarProc_ to item i_ of ProcNm_ --display dialog TarProc_ try if TarProc_ is not "Finder" then tell application TarProc_ to quit "without saving" end if end try end repeat try do shell script "sudo /sbin/shutdown -h +1" end try quit I hope somebody can help me. b. r.
