Well, also in the same predicament, hopefully a solution or update emerge soon…
Topic summary
Safari Version 18.0 (20619.1.26.31.6) is causing an infinite loop when attempting to allow third-party cookies in Shopify’s theme editor, preventing users from accessing the editor.
Key Issues:
- The browser repeatedly prompts users to enable cookies despite settings already being configured correctly
- Users are experiencing constant logging in/out issues, particularly when using Safari’s developer tools
- This appears to be a recurring problem that previously occurred in 2020
Workarounds Mentioned:
- Disabling Safari developer tools may resolve the logging out issue
- Using Safari Technology Preview instead of the full Safari version can bypass the cookie loop problem
Current Status:
- One user reported the issue resolved itself after trying again the following day, though no actual Safari update was released
- The root cause appears to involve both Apple and Shopify, with users calling for an urgent fix as many store owners rely on Safari for theme editing
