This seems to be what I need. Vector operations and such. https://developer.apple.com/library/archive/documentation/Performance/Conceptual/vDSP_Programming_Guide/Introduction/Introduction.html and https://developer.apple.com/documentation/accelerate/veclib The Neural Engine looks versatile.

Hi, PostScript is a stack based programming language. Might be you should try to solve it in PostScript level 3 itself. Search online for "Postscript Primer" or "Postscript Language Reference". PDF is a PostScript level 3 dialect. regards, Joël

I have got the same problem as using Xcode.

Hi, I was able to fix error message #01 but #02 still makes problems. Asset validation failed (90259) Bad Bundle Executable. You must include a valid CFBundleExecutable key in your bundle's information property list file. (ID: 20d29eb7-40a8-4a38-ac75-2a75452d04cf)

codesign did the job.

I think it is necessary to sign first the binary, because else App sandbox won't work. So first: codesign --entitlements /Applications/MyApp.app/Contents/MyApp.entitlements -s "Apple Distribution: ****" /Applications/MyAppapp I checked the installer package in a VM. It works with sandbox.

After this I validated the package successful. xcrun altool --validate-app -f ****-universal.pkg -t osx -u ****

And upload succeeds. xcrun altool --upload-app -f MyApp-universal.pkg -t osx -u ****

on macOS for App Store.

This was due to different location of config file within sandbox.

man dyld and check for debugging environment variables to turn on diagnostics. Check for failed initializers helped me. Actually 2 libraries the plugin was using were not found. problem fixed. by, Joël
