Lighting Issues When Transferring from PC to Mac
I'm currently working on a project on both a Mac and PC, transferring the project manually when necessary. The transfer goes smoothly, with all assets and materials generated properly, but I'm having an issue with lighting. I created the lighting on the PC, and it looks great. Then I transfer the whole project over to the Mac, and the lighting in many of the locations is significantly darker than it appears on the Windows version. I checked the light values, and they're consistent across the platforms.
Is this a known issue? I could certainly attempt to tweak the lights manually on the Mac to get the desired brightness, but this would cause issues when I transfer back the the Windows.
Any advice for getting consistent lighting?
See the images below for comparison.

This is the same room, same materials, and same lighting on the Mac.

My issues have cleared in the meanwhile. I'm thinking this related to various platforms working off a cloud and opening into different engines. Once we all got on the same page with the same engine, synced to the same project file, the problem went away. Can't be certain it's that simple, but possibly is.

Sorry for the late response.
To remedy this, I had to adjust the lighting intensities and values manually on the Mac version to match the appearance of the PC version. Unfortunately, I wasn't able to find anything that was more efficient than this.

Ok After digging around to answer this question for myself I found out the issue is caused by OpenGL and therefore Mac not supporting Eye Adaption. So on PC, if the lighting is too dark they camera adapts to bring up the exposure, on the Mac, it just stays dark.
So the solution is to adjust the lighting to be more intense, like has been posted here. If you want to disable this feature on the PC version so you can match the lighting between both builds, you need to disable it for each camera, including the player camera included in your blueprints. Once you select the camera, in the details window go to Camera Settings > Post Processing > Auto Exposure. Then disable all but the Min and Max Brightness and set these to 1. Now you lighting will stay the same. Of coarse if you like or need that feature you are out of luck as far as I can find. Hopefully when Unreal implements the Metal API support this feature will work, here's hoping.
