The AppleScript script below returns a -600 error (application not running) under STP Tahoe version 231 and macOS 26.1. It functioned flawlessly under previous STP versions under macOS 15.x and 14.x.
tell application "Safari Technology Preview" tell front window set _old_tab to current tab set _new_tab to make new tab at after _old_tab set current tab to _new_tab end tell end tell
The following version returns a syntax error.
Tell application "System Events" Tell process "Safari Technology Preview" tell front window set _old_tab to current tab set _new_tab to make new tab at after _old_tab set current tab to _new_tab end tell end tell end tell
How would these scripts need to be fixed for STP 231 for Tahoe?
