Hi Alberto,

1) I can not find your report concerning Macos anymore myself.
I will double check with the support system team.
And the report #19837 is clearly something else, and from another user.

> I can’t enter the account I used to ...
Can you give me more information about that account ?  username, email address ?

Did you change anything on that previous account ?
Try renaming the username, or change the email , or else ?

2) On the original issue related to macosx:

For manual installation on Mac,

export ISE_EIFFEL=/Users/alberto/Eiffel_X.Y
export ISE_PLATFORM=macosx-x86-64
export PATH=$PATH:$ISE_EIFFEL/studio/spec/$ISE_PLATFORM/bin

I guess "Eiffel_X.Y" is really Eiffel_21.11 .. or the directory name where you extracted the archive.

To launch EiffelStudio from the command line, either use
$ estudio
or
$ ec -gui

on specific Eiffel project:
$ estudio path-to-project.ecf
or
$ ec -config path-to-project.ecf -gui

Let me know if this is not working for you.

Best regards,
