app bundle won't run on macos 10.14

[gmarinov]

• "m8c-20220830-macos.zip" download from https://github.com/laamaa/m8c/releases/tag/v1.3.0
• macOS 10.14.6 (Mojave)
• M8 connected via USB

expected: double-clicking downloaded app runs m8c.

actual:

• it displays incompatible app icon
  
• double-clicking the app shows a "This application requires macOS 10.13 or later" prompt.
  
• running from the console segfaults:

xattr -r -d com.apple.quarantine path/to/app.app doesn't fix it

but works from source

compiling from source, e.g. make and then ./m8c works fine:

Dang. Could someone else with a mac try the package too and see if it's broken for everyone? I probably won't have time to debug the build/packaging anytime soon as I don't have easy access to a mac :/

i tried to tweak the Info.plist file or the adjacent files but nothing worked, until I replaced the m8c binary itself with the one I compiled from source. The downloaded one is ~75kb, the compiled one I have is just over ~40kb.

otool on both looks very similar.

Seems like Github Actions has recently switched to a newer Mac OS version in the builds... I tried manually triggering a new build, could you please check if this works any better?
m8c-20221117-macos.zip

[gmarinov]

this is better. the wrapper app still won't open directly from the finder.
however, the binary no longer segfaults, so I'm able to "show package contents" and then use "open" from inside it.

I think someone with the proper skills (and a computer for testing...) should rewrite the OSX build thing :)

Schism Tracker for example nowadays seems to have a nice way to automatically cross-compile it directly to both Intel and ARM, but unfortunately I do not have the time to get too much into how it works...

[laamaa]

The build system was updated a little, could you please test if this build works?

• no luck as an app, i'm afraid.
• the binary inside opens without segfaulting, after I de-quarantine it manually.
• could this be relevant? https://stackoverflow.com/a/44692821

This should be fixed in the latest release, please check if it works better now and post here if the problems still persist.

Please note: When running the program for the first time on MacOS, it may not open as it is from an Unidentified Developer. You need to open it from the Applications Folder via Control+Click > Open then select Open from the popup menu.
