MailMerge is improving each time ! However, since last time I used it with personnalized attachments, I moved to MacOS. I can't find the way to give the right path to the files and have it attached to the mails generated

ਇਹ ਸਮੀਖਿਆ ਐਡ-ਆਨ (9.1.0) ਦੇ ਪਿਛਲੇ ਵਰਜਨ ਲਈ ਹੈ। 

You must select the files manually in the field "Attachments -> File" in the Mail Merge Dialog. Then specify the filename in the field "Attachments -> Attachments". See:
