Try not to keep more than 4,000 files in a single folder.
Fujifilm has warned its customers that a firmware issue can prevent them from viewing images on macOS—but only if they have more than 4,000 files in a single folder on an SDXC card. The company says the flaw is found in a dozen X and GFX series cameras. Nine of them—the GFX100, GFX100S, GFX50S II, X-Pro3, X-T4, X-S10, X-E4, X-T30 II, and X100V—are affected regardless of their firmware version. The GFX50S, GFX50R, and X-T3 cameras are only affected by the problem if they’re running specific versions of their respective firmware. Fujifilm says the underlying issue results from the X and GFX series camera firmware allowing the devices to store up to 9,999 frames in a single folder. (Each frame, according to the company, can create up to three files depending on how the user is storing their photos.
