A menudo guardo todos mis archivos personales dentro de una imagen dispersa, y me doy cuenta de que la vista previa incorporada a menudo se congela al ver archivos jpeg / gif / png / pdf. Puedes ver los caramelos girando durante 30 segundos antes de que vuelva a funcionar.
Al mirar dentro de la consola, vería el siguiente mensaje de error
4/13/12 9:41:33.334 AM sandboxd: ([28519]) Preview(28519) deny file-issue-extension /Users/Antony/Documents/Secured.sparsebundle

La pregunta es: ¿hay formas de evitar los problemas de congelación aleatoria? ¿Hay algún permiso que pueda configurar para que la Vista previa pueda comportarse felizmente? Llegó al punto de que ya no uso la Vista previa para PDF (uso Skim).
