Adobe has released a version of Lightroom optimized for Macs with M1 CPUs. This is the “cloud” version (the multiplatform version based on online storage), and not yet Lightroom Classic, for which we will have to wait until next year.
The update (version 4.1) is available on the Mac App Store and via the Creative Cloud utility. The editors of the French Macg to have performed some tests, making a brief comparison on a MacBook Air M1 between Lightroom run through Rosetta 2 and Lightroom in the native version. Exporting 300 RAWs (stored locally) as full-size JPEGs at 100% quality took 7 minutes and 53 seconds via Rosetta compared to 5 minutes 11 seconds with the optimized version. Although optimized for the Apple Silicon architecture, Lightroom is demanding in terms of RAM. It is best to use this type of application with machines with 16GB of RAM.
Adobe explains that the December 2020 release of Lightroom (4.1) offers support for new cameras, lenses, and bug fixes. The Adobe website lists the models of supported cameras he targets supported (including iPhone 12 and iPad Air 4). The application now offers a widget to quickly open the camera, discover tutorials and guides. Version 4.1 of the software is also available as a native version for Windows ARM computers
