Intentando forzar update_dyld_shared_cache pero teniendo algunos errores

Lo que me solucionó fue

update_dyld_shared_cache -debug

Esto es lo que debería ver

update_dyld_shared_cache: adding root: /System/Library/...
...
...
update_dyld_shared_cache: /var/db/dyld/dyld_shared_cache_i386 is up-to-date
update_dyld_shared_cache: /var/db/dyld/dyld_shared_cache_x86_64 is up-to-date

para estar seguro de que funciona, ejecuto

update_dyld_shared_cache 

una segunda vez

Reinicie su mac en modo de recuperación ( https://support.apple.com/en-ca/HT201314 ), Abra allí la Terminal y escriba

rm -rf /Volumes/<your_system_volume>var/db/spindump/*

Después de eso reinicia tu mac y repite la operación

sudo update_dyld_shared_cache -root / -force

PS ver el comentario detallado de @CharlieMonroe

La bandera -debug en update_dyld_shared_cache no hace nada, excepto proporcionar más detalles sobre el trabajo que se está haciendo - que es hace el informe más verboso.

Yo usaría: sudo update_dyld_shared_cache -Root / -force

Todos los sistemas proporcionan "errores", aunque no son problemas, sino información sobre lo que no se puede hacer u omitir debido a la forma en que está implantado el módulo.

Estos son los "errores" típicos de un sistema saludable:
