changement/oubli du chemin d'accès au dossier Dropbox (avant install)

Changement de mac, changement de nom d'utilisateur : gerald (effacement de l'ancien : aldje_1), malgré toutes les tentatives de purge des fichiers et dossiers Dropbox antérieurs, l'installateur continue de rechercher (dès la saisie du mdp admin pour "modifier les autorisations du dossier" un dossier dropbox chez l'utilisateur inexistant (/Users/aldje_1/.dropbox) et bloque l'installation en proposant le rapport d'erreur ci-après. 

J'ai tenté l'application de :  sudo mv ~/.dropbox ~/.Trash/dropbox.old dans le terminal (comme conseillé) : je n'ai pas les droits de sudo avec mon utilisateur courant et je me fais jeter, et il n'y a pas de dossier dropbox dans mon compte admin évidemment. 

D'avance merci pour votre aide, Gérald

P.S. j'ai vu passer une histoire de protection spécifique à Tahoe 26.2, mais je n'ai pas compris la solution s'il y en a une.
