Impossibile installare Inkscape su macOS High Sierra 10.13.6 (17G65) tramite DMG o Homebrew

Ho provato ad installare Inkscape 0.92.2 via DMG (Xquartz) e via Homebrew (Cask), avendo precedentemente installato Xquartz (2.7.11) senza problemi, sul mio Macbook Pro 13.

Una volta installato Inkscape, non si aprirà - dal DMG e dall'installazione di Homebrew viene visualizzato il seguente messaggio di errore:
