Our team are also blocked by this and have no means of rolling back our MacOS systems to 26.3. MacOS is now at version 26.5 and CircleCI is using 26.3.1… As a result, we have to push changes and wait for CI to generate/update the goldens, which adds significant turnaround time to what should normally be a fast local workflow.
This is starting to have a noticeable impact on development velocity and confidence in our test pipeline.
Others are impacted by this too ~ Xcode 26.4.1 Released - #10 by OliverNarramore
Hopefully CircleCI can rapidly release a fix for this or even offer a preview image to unblock us.
