Hey Yvan,

Thanks. I'd forgotten that little gimmick.

Running in the Script Editor with the Log History window open I get:

-------------------------------------------------------------------------------------------

tell application "Finder"

get POSIX file "/System/Library/Fonts/Menlo.ttc"

--> error number -1728 from POSIX file "/System/Library/Fonts/Menlo.ttc"

end tell

Result:

alias "Mercury:System:Library:Fonts:Menlo.ttc"

-------------------------------------------------------------------------------------------

-1728 → The referenced object doesn’t exist. This is a run-time resolution error, such as when attempting to reference a third object when only two objects exist.

-------------------------------------------------------------------------------------------

The code works and yet produces an error.

I continue to prefer to keep the Finder and POSIX Paths widely separate.

The Finder likes aliases, HFS paths, and FURLs («class furl»). When I stick to those I rarely have any problems.

Since System Events is better behaved these days and understands $HOME-based POSIX Paths, I don't mind using it in an alias-from-path-string handler:

-------------------------------------------------------------------------------------------

set thePath to "~/Downloads" -- $HOME-based POSIX Path.

set myAlias1 to makeAliasFromPathString(thePath)

set thePath to "/Users/chris/Downloads" -- POSIX Path

set myAlias2 to makeAliasFromPathString(thePath)

set thePath to (path to downloads folder as text) -- HFS Path

set myAlias3 to makeAliasFromPathString(thePath)

on makeAliasFromPathString(thePath) -- Input: POSIX-Path, Tilde-Path, or HFS-Path

tell application "System Events" to set thePath to POSIX path of disk item thePath

return (POSIX file thePath) as alias

end makeAliasFromPathString

-------------------------------------------------------------------------------------------

Take Care,

Chris
