Hello, as the title says, I am having trouble getting my Mac version of Aseprite to open files saved on Windows 10. I receive the error of “Error reading header”.
The files are synced via Dropbox and I am able to always work on the file on Windows 10.
Welcome @matp! Could you please share one of those .aseprite file with us at support@aseprite.org?
We use Dropbox to share .aseprite files between Windows <-> macOS and didn’t notice this issue, but it might be a problem in some cases maybe.
Sure! Sending 
thanks!
