Hola Jose Luis. ¿Qué formato de disco es el disco duro externo? Lo más probable es que tenga formato NTFS, que es de solo lectura en macOS a menos que esté ejecutando un software especial. Cuando actualizaste tu sistema operativo, probablemente se rompió el software especial que estabas ejecutando anteriormente.
Adobe Lightroom 6 Dvd
Adobe has tested running the latest versions of Lightroom CC 2015/Lightroom 6 with macOS 10.12 (Sierra) and found no significant issues. Adobe recommends that customers update Lightroom to the current version prior to updating to macOS 10.12 (Sierra). Adobe Lightroom (officially Adobe Photoshop Lightroom) is a creative image organization and image manipulation software developed by Adobe Inc., as part of the Creative Cloud subscription family. It is supported on Windows, macOS, iOS, Android, and tvOS (Apple TV).Its primary uses include importing/saving, viewing, organizing, tagging, editing, and sharing large numbers of digital images. Fortunately, both are features that users have been waiting for the most since the initial release of Lightroom, a great move from Adobe indeed. This software supports the latest macOS Catalina perfectly. Not only Catalina can install this application, Mojave, and High Sierra can also add Lightroom 2020 without any problem.
