When running Julia in VSCode, I’ve seen this message a few times:

 ![Mac system Privacy and Security warning saying "Visual Studio Code" was prevented from modifying apps on your mac](https://global.discourse-cdn.com/julialang/original/3X/6/d/6d6e88ba47800f58912127f09cfd64d48d585042.jpeg)

Digging into the syslog a bit (using the `log show` command), I see this:

It appears that Julia is trying to write compiled code inside the Julia app bundle, as opposed to in .julia. Since Julia is running inside VSCode, the Mac sees this as VSCode trying to modify Julia and spits out this warning. Is it possible to have julia write .ji files in .julia instead of inside the app bundle?
