39## Getting started

40 

41Codex applies sandboxing automatically when you use the default permissions

42mode.

43 

44### Prerequisites

45 

46On **macOS**, sandboxing works out of the box using the built-in Seatbelt

47framework.

48 

49On **Windows**, Codex uses the native [Windows

50sandbox](https://developers.openai.com/codex/windows#windows-sandbox) when you run in PowerShell and the

51Linux sandbox implementation when you run in WSL2.

52 

53On **Linux and WSL2**, install `bubblewrap` with your package manager first:

54 

55```bash

56sudo apt install bubblewrap

57```

58 

59```bash

60sudo dnf install bubblewrap

61```

62 

63Codex uses the system `bwrap` at `/usr/bin/bwrap` when it is available. If it

64is missing, Codex falls back to a bundled helper, but that helper requires

65unprivileged user namespaces. Installing your distro’s `bubblewrap` package is

66the most reliable setup.

67 

68Codex surfaces a startup warning when `bwrap` is missing or cannot create user

69namespaces. On distributions that restrict them with AppArmor, you can enable

70them with:

71 

72```bash

73sudo sysctl -w kernel.apparmor_restrict_unprivileged_userns=0

74```
