macOS 26 Tahoe se actualiza a la versión 26.6 (25G72) para corregir unas cuantas vulnerabilidades, y de paso preparar el índice de Spotlight para la próxima versión de macOS 27 Golden Gate.
Actualizado sin problemas, tanto en mi MacBook Air M5 como en mi Sagar Hozkatua.
El único "pero" que me he encontrado ha sido LuLu, el firewall que utilizo para el control de conexiones salientes a Internet, que necesita ser actualizado a la nueva versión 4.4.3 que han publicado hace un rato.
objective-see.org
Tiene pinta de que el acceso a los nuevos modelos de IA como Fable de Anthropic les está permitiendo identificar vulnerabilidades a toda máquina, porque el número de CVEs que se corrigen es bastante alto.
Safari se actualiza a la versión 26.6 (21624.4.5.11.5), pero viendo las notas de la versión, aquí hay mucho más tomate.
