So, Linux gets a free pass for requiring chmod +x to run his tool, but needing to run xattr on MacOS is somehow worthy of an entire blog post to complain about it? Serious question - Is it really true that Windows 11 will run an untrusted .exe without a warning?
This is a Claude Code tool for developers. I'd assume that any potential user for this tool should be perfectly able to run that xattr command (and if they are not, they probably shouldn't be playing around with Claude Code either... yup, some additional "gatekeeping" from my side here).
You could probably even make some curl -sL https://github.com/myrepo/installme.sh | bash script for these users which takes care of the xattr command.
Your typical macOS enduser does not use command line tools. Or they use something like Homebrew.
Btw the proper way to distribute binary would probably be pkg installer.
