Este Applescript hará clic en el botón "Sync" en Finder en una ventana que ya tiene el dispositivo abierto:
tell application "System Events" to tell application process "Finder"
click button "Sync" of splitter group 1 of splitter group 1 of window "device name"
end tell
El siguiente Applescript navegará por la "ventana 1" del Finder hasta el dispositivo llamado "nombre del dispositivo", donde se encuentra el botón "Sync".
tell application "System Events" to tell outline 1 of scroll area 1 of splitter group 1 of window 1 of application process "Finder"

repeat with e in theElements
try
if name of e is "device name" then
tell e to perform action "AXOpen"
exit repeat
end if
end try
end repeat
end tell
