Ogni volta che voglio cambiare lo stile del testo in iBooks, l'app non risponde. Lo uccido nel terminale ( killall iBooks ), quindi il sistema segnala che CoreText.FontDownloadHelper si è arrestato in modo anomalo. La mia teoria attuale è che se dovessi risolvere CoreText.FontDownloadHelper , allora il crash in iBooks non si verificherà più. Ho ragione?
Ecco il rapporto di arresto anomalo, con l'UUID rimosso.
