It sounds like you need a reliable way to test your Webflow site in the latest version of Safari to troubleshoot a flickering issue. Since Safari is exclusive to macOS and iOS, here are options for emulating or accessing it:
1. Use a macOS Virtual Machine
- BrowserStack and Sauce Labs offer cloud-based macOS VMs with Safari.
- Download Apple’s Safari Technology Preview on a Mac for the latest version.
2. Enable Responsive Design Mode in Safari (Mac Required)
- Open Safari, then go to Develop > Enter Responsive Design Mode.
- This lets you simulate various devices while using Safari’s latest rendering engine.
3. Test on a Real macOS Device
- If you have access to a Mac, check the issue directly in the latest Safari version.
- Ask a colleague or use a Mac in a coworking space if needed.
4. Try Online Testing Services
- BrowserStack (paid) provides real Mac environments.
- LambdaTest has cloud-based macOS testing with modern Safari versions.
5. Install macOS on a Virtual Machine
- Set up macOS in VirtualBox or Parallels (Mac required for official macOS VMs).
- Install Safari and test Webflow directly.
Summary
The best options are BrowserStack, Safari on a real Mac, or Responsive Design Mode in Safari. If you need a free method, try borrowing a Mac or using Apple’s Safari Technology Preview on macOS.
