Comment(by leif):
That's a matter of the current umask, but we could of course change the
file permission on updates to that file. On the other hand, opening an
existing file for writing shouldn't change the permissions in the first
place. If the file gets deleted inbetween, an ordinary user would also
need write permissions ''on the directory'' the file is located /
recreated in, i.e. `$SAGE_ROOT/local/lib/`.
It's not immediately clear to me why an ordinary user would have to move
Sage though, just to run the application. (But I don't use apples.)
Allowing the ''group'' to write to this file would certainly be better,
putting potential users (that move the installation) into that group. (But
they still won't be able to actually modify / fix hardcoded paths, which
is the whole purpose of `sage-current-location.txt`, so the installation
might actually break if it ''really'' moved. A better detection in the
code that attempts to update that file is another alternative.)
The whole issue might be related to #5852 (and previously #11707), such
that after this ticket is resolved, changing the permissions may no longer
be necessary.
