I've had similar experiences with MacOS. I uncheck that goddamn box all the time and still it relaunches previously opened applications half the time. If my application or computer crashes, I don't want the crashy application to open up at startup again. MacOS isn't perfect.

OSX is particularly lousy with remembering user preferences and configuration. I quit using it after I grew sick of raging at it forgetting what applications want different files to open with. I've never had this sort of problem on Linux.

In my experience, when filetype associations change under macOS it’s because some app I’ve used recently has made those changes without asking me.

I know some people are tired of all the prompts but I don’t think apps should be able to change those associations without first prompting the user.
