Operating System

macOS (Apple Silicon)

Describe the bug

When attempting to run a deployment script using forge script on macOS, I consistently encounter the following error:

nginx
copy code
Internal transport error: Socket operation on non-socket (os error 38)
This happens even on the latest version of Foundry, and despite using valid RPC and private key values.

Command:

bash
Copy code
forge script script/deploySimpleStorage.s.sol
--rpc-url $Sepolia_RPC_URL
--private-key $PRIVATE_KEY
--broadcast -vvvv
Expected behavior:
The script should execute and deploy the contract without error, assuming the provided RPC and private key are valid.

Actual behavior:
The command fails with:

nginx
Copy code
Internal transport error: Socket operation on non-socket (os error 38)
Environment:

Hardware: MacBook Air M1

RPC node Provider: any providor

Project location: Local drive (not cloud-synced)

System Integrity Protection: Enabled

Used sudo?: Only for testing — not needed when bug appears

Steps to Reproduce:

Create a Foundry project

Write a simple deploy script without any vm.createFork usage

Run with forge script using a valid --rpc-url and --private-key

Observe error output

Notes:

Bug disappears when running with sudo (likely a permissions/sockets issue)

No forking is being used

.env variables are correctly exported

Happens even when run from env -i bash --noprofile --norc (clean env)

Possibly related to how sockets or file descriptors are handled on macOS

@anas3182003 thanks for your report, this is likely related to your OS / user settings (could be SIP) as you mentioned it works as sudo, and nothing we could do in foundry. Please review your user settings, going to close for now.
