1. When I type clang hello.c, I run into the same issue of the terminal hanging.gcc --version produces the following output:Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/include/c++/4.2.1Apple clang version 11.0.0 (clang-1100.0.33.17)Target: x86_64-apple-darwin19.3.0Thread model: posixInstalledDir: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin2. Internet does not have anything to do with compiling the source code. I was just noting that this was a strange side effect that I do not know how to explain; when my terminal hangs, my google chrome windows say that I lost internet connection for some reason.Also, yes I am using the Terminal.app from /Applications/Utilities3. I'm not too sure what else to be trying at this point. I haven't found anyone/anything online with this similar issue. I've called two different Apple support people and have visited the Apple store in-person with no luck unfortunately. Thank you for trying to help though!
