Apple this week released its new Big Sur operating system. (Read about it from CNN here.) In advance of this the Adobe Lightroom
team worked to make Lightroom Classic 10.0, cloud-based Lightroom 4.0 and Photoshop 22.0 compatible with Big Sur.
Lightroom Classic Compatibility with MacOS Big Sur
- As of Nov. 13, 2020 there are no known issues with Lightroom Classic 10.x.
- Compatibility of Lightroom Classic 9.x (and all earlier versions) was not tested and is not guaranteed.
- If you’re running Lightroom 6 or an even earlier version, you should never update to Big Sur (or Catalina). Read my Catalina article for why.
- Apple M1 processor support: Native compatibility for these new processors in new 13″ Mac Book Pros and Mac Minis will be added in a 2021 release. In the meantime Lightroom Classic can be run in Rosetta 2 emulation mode (though Adobe doesn’t officially support it, meaning they can’t take responsibility for emulator issues). There are no known issues with this. Do expect emulation mode performance to be slower.
- Adobe will keep this Lightroom Classic / Big Sur compatibility document up-to-date with known issues.
Cloud-Based Lightroom Compatibility with MacOS Big Sur
Photoshop Compatibility with MacOS Big Sur
- Photoshop 22.x is compatible with Big Sur. As of Nov. 13, 2020 there are some known issues – click through on the link below.
- Compatibility of Photoshop 21.x (and all earlier versions) was not tested and is not guaranteed.
- Apple M1 processors: native support will be added in a 2021 release. Photoshop 22.x can be run in Rosetta 2 emulation mode, but there are known issues – for these, click through on the link below. Do expect emulation mode performance to be slower.
- Adobe will keep this Photoshop / Big Sur compatibility document up-to-date with known issues.
Should I Update to MacOS Big Sur?
For most of you, I don’t recommend updating to Big Sur until its been out at least a few months (and possibly longer if Lightroom compatibility issues are identified and/or Photoshop issues aren’t yet resolved – waiting 6-9 months is not unreasonable).
Keep in mind also that Lightroom and Photoshop compatibility with Big Sur is not the only thing you should be concerned about – before updating you should research whether your printer and scanner drivers are compatible, tablets, and other peripherals, other apps you use, etc.. I hear that testing all your apps and peripherals while running Big Sur on a separate partition is an option, but this is way out of the scope of this blog.
