Our team is performing web automation using Playwright and I am doing testing on your macOS Catalina but I’m getting an error: browserType.connect: Running Playwright tests with webkit is not supported on MacOS Catalina. Please use the OS version Big sure or higher.

Hi Mark,

We had enabled webkit on macOS Catalina previously as they were working with the older versions of Playwright. However, the recent versions do not support it, and for this reason, we have removed it to prevent errors on your end.

Adding on to this, I’m afraid you won’t be able to install the older Playwright version to test webkit with Catalina, which are also the older macOS versions.

For your reference on the same, please click these links:

Put down a short code snippet that illustrates your bug and that we can run and debug locally. For example: ```javascript const {chromium, webkit, firefox} = require('playwright'); (async () => { const browser = await webkit.launch(); const context = await browser.newContext(); const page = await context.newPage(); await page.goto('https://example.com/') await page.locator(…); })(); ``` **Describe the bug** Running a test on MacOS Catalina with Webkit browser gives the error: ``` browser.newPage: Protocol error (Page.setForcedColors): 'Page.setForcedColors' was not found [{"code":-32601,"message":"'Page.setForcedColors' was not found"}] ``` This error occurs for Playwright version >= 1.25.0.
