Why can’t I delete, rename, or edit certain files on the Mac?

Files that cannot be deleted, renamed, or edited on Mac.
Macs have the concept of “flags” which live alongside filesystem
permissions for a file.  In particular they have a “read only” flag that
trumps whatever the filesystem says a user’s or group’s access is
supposed to be.  If this flag is set on a file, you cannot rename,
delete, or edit that file even though you would be able to on a Windows
or Linux machine.  Other BSD based systems also respect this flag –
including the Isilon itself which is why it matters for DartFS.
The reason this should be a FAQ (or at least an OAQ) is that there are
Mac tools that set this flag.  RCS (version control) is one example and
there may be others.
On the Mac, you can see if this flag is set by using the -O option to
‘ls’.  It will show up as ‘uchg’.  To manually remove it, use
‘chflags nouchg file’

Does ArcGIS run on a Mac?

ArcGIS software does not currently run on the Mac OS. Mac users can install a “virtual machine” and run Windows inside their Mac OS, or they can use an open-source GIS software package such as QGIS.
