Automatically restart crashed user-launched app

The simplest trick is to also run an AppleScript that restarts Mail if it quits. To make the script, launch Script Editor.app and paste this code into it:

on run

doit()

end run

on idle

doit()

return 60 -- in seconds

end idle

on doit()

tell application "System Events"

set mailApps to every application process whose bundle identifier is "com.apple.mail"

if (count of mailApps) is 0 then

tell application "Finder"

launch application "Mail"

end tell

end if

end tell

end doit

Save it as an application, with the option "Stay open ..." checked. Then place this app somewhere you like, e.g. into your Applications folder, and start it. To make sure it starts even if your Mac is restarted, add it to your Login Items, e.g. by ctrl-clicking its icon in the Dock and choosing the option "Open at Login".

Another way is to use launchd (I tried that but wasn't happy with the results). The link you posted is rather outdated, for OSX 10.4. 10.5 added a new option to react to crashed apps, explained in this MacOSXHints article.

Hi, So glad I found this any way you can switch the script for Plex Media Server. This would be a huge help. Not sure what to change in your script to allow this. Truly appreciate any help you can offer!

Thanks

You'll have to replace "com.apple.mail" with the bundle identifier of the program you want to have restarted, and replace "Mail" with the name of the program.

I can't tell you the bundle identifier for Plex Media Server, though. It's something you'll have to google or ask for help on how to figure that out the bundle identifier of any Mac app.

Thanks for the speedy reply. Yes figured that would be the case. Forgot Google is my friend. Appreciate it!
