Hi @sinshade
Regarding this message: Local is requesting administrative privileges to modify your /etc/hosts file
That is expected behavior since Local will need to access this to be able to update domains and so on. You may need to search on your machine to be able to find and allow Local in the settings. This might help: Help! I'm running into an EPERM error with the hosts file on Windows
As far as trusting we have another help article here that goes into more detail and extra troubleshooting steps, but once you resolve the first piece this might work more seamlessly.
