All,
I want to follow the following procedure to restore /opt/local to
previous date from time machine external drive,
but I get “Time Machine” can’t be modified or deleted because it’s
required by macOS." error message after I click "restore" button.
Do you know how to fix it?
Thanks,
Tao

Proceed as follows:
* Open a Finder window.
* Enter Time Machine.
* Press ShiftCommandG and enter |/| to display the root folder of your
drive.
* Press ShiftCommand. to display hidden folders. You should see |/opt|
now.
* Browse the timeline on the right-hand side and select the desired date.
* Select |/opt|.
* Press Restore. Note that Time Machine will probably ask whether you
want to keep a copy of your current files.
