First I am impressed by the effort that is put into following up close ESO scisoft releases and its porting to Macs. Making it even more Apple-like by installing in the App. structure is a great idea. It allows a better management of the Mac files.

BUT: it seems this new versions has some teething issues:

1- this new version won't install properly on a *case sensitive formatted file system*. The App. folder structure includes folder's names with upper and lower cases, which are not mirrored in the installation/Setup scripts,
E.g. for midas and iraf, the path are given ALL in lower cases will the real path need to be set with upper cases.

2- Some symbolic links follow a path that is incorrect (irespective of Upper/Lower case issue).
