After updating from Safari 13 to Safari 14 (on macOS 10.15.6), I have noticed that all of my text-filtering Automator workflows no longer work correctly when invoked from the updated Safari.
For an example of such a workflow, see the screenshot below.
It shows a simple workflow that takes the current text selection,
pipes it through the fmt
command, and replaces the original
selection with that command’s output:
I have a few workflows of this construction, i.e., consisting of a single Run Shell Script action running a command that takes the text selection on its stdin and outputs the text to replace the selection with on its stdout. I have been using them without any issues for quite a long time (at least, for the last two major releases of macOS).
However, when a workflow like that is run from the newly updated Safari 14, it fails to replace the text selection with the output of the workflow. Instead, it simply deletes the selected text. The issue is clearly specific to Safari 14 only, because the same workflows still work correctly (i.e., replace the selection with the command’s output) in all other apps (e.g., TextEdit).
Is this caused by some security-related novelty in Safari 14 that can be disabled, or is it simply a regression bug that has been introduced in this update? Are there any known workarounds aside from simulating copying and pasting for the command output in Automator workflows?
