Hi,

the instructions you are referring to, are these, right?

Open a "terminal" window (in Finder: Menu "Finder → Service → New terminal in folder"; or press "Control-Option-Command-T" while selecting the folder from its parent folder). Enter the following command there:
sudo xattr -r -d com.apple.quarantine ~/Downloads/jcryptool.app
(assuming you extracted JCrypTool directly in the folder "Downloads"; otherwise, adapt the command accordingly. The .app file ending should be kept.)

Could you please verify that your Downloads folder contains a file jcryptool.app after extracting the downloaded archive?

[bigray0x]

Yes that's it and the folder does contain the app after extraction

Precisely ( application folder)

Could you try replacing ~/Downloads/jcryptool.app in the command line with the full path to jcryptool.app? (and would you also share that path if you don't mind?)

Wish I could and I sorted it out
