However, seems sandbox feature is not very stable, and we cannot make it work on some platforms.\n\nOn Windows:\n\nFrom docs, it should work for version 26300.8553, however, one machine with this version works fine and other one show errors:\n`Experimental_CreateProcessInSandbox returned E_NOTIMPL. The following velocity keys are not enabled: 61389575, 61155944.`\n\nTwo machine has the same version as below:\n```\nEdition\tWindows 11 Enterprise Insider Preview\nVersion\t26H2\nInstalled on\t‎2026/‎7/‎6\nEvaluation expires on\t‎2026/‎8/‎12 2:09\nOS build\t26300.8758\nExperience\tWindows Feature Experience Pack 1000.26100.402.0\n```\n\nOn Linux:\n\nIt always show command failed after enable sandbox, maybe there is a version requirement?\n\n\u003cimg width=\"1595\" height=\"575\" alt=\"Image\" src=\"https://github.com/user-attachments/assets/fba7df51-523d-4321-b9aa-8de012fa053c\" /\u003e\n\n\u003cimg width=\"618\" height=\"480\" alt=\"Image\" src=\"https://github.com/user-attachments/assets/40dac985-9cf1-4d75-9e2a-c74b2be460ce\" /\u003e\n\nOn Mac:\nWhen a sandboxed command is launched on macOS Seatbelt with a process working directory that is not allowed by the sandbox policy, the child shell can print noisy getcwd warnings during startup.\n\nThe command itself may still succeed, especially when it uses an absolute path that is allowed by the policy. The issue is confusing stderr noise, not a command failure .\n\n\u003cimg width=\"576\" height=\"439\" alt=\"Image\" src=\"https://github.com/user-attachments/assets/914aae0e-684f-44f3-abb7-e61d086eec8d\" /\u003e\n\nI think this is related MXC and we already create an issue here: https://github.com/microsoft/mxc/issues/611\n\n\n\n### Affected version\n\n_No response_\n\n### Steps to reproduce the behavior\n\n_No response_\n\n### Expected behavior\n\n_No response_\n\n### Additional context\n\n_No response_","author":{"url":"https://github.com/SLdragon","@type":"Person","name":"SLdragon"},"datePublished":"2026-07-07T08:49:48.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":0},"url":"https://github.com/4046/copilot-cli/issues/4046"}
