Inizia riproducendo il problema su macOS 11.7.10 con l’ambiente Intel indicato, quindi esegui q doctor e q restart come descritto. Traccia il modo in cui il binario bun di kiro-cli viene selezionato o distribuito e verifica che kiro-cli si avvii senza l’errore di simbolo dyld sulla versione di macOS interessata.
