The Xcode 26.4.1 image has been released and can be selected as follows:
macos:
xcode: 26.4.1
Apple Silicon VM Image Info
Xcode 26.4.1 Build version 17E202 is installed at /Applications/Xcode-26.4.1.app
The full manifest of installed software can be found here
Does this release intentionally remove support for xcode:26.4.0? We began seeing this error correlating around the same time as your release of 26.4.1.
Job was rejected because resource class m4pro.medium, image xcode:26.4.0 is not a valid resource class
I found this in the docs:
Xcode 26
We retain the three latest major.minor versions at the latest patch version
I would just provide feedback that this is somewhat inconvenient and supporting all patch versions of the latest major.minor seems quite reasonable.
Thank you for the message. The release of Xcode 26.4.1 should not have intentionally remove support for Xcode 26.4.0. This should be fixed shortly.
Sorry for the inconvenience. I’ll take this feedback around Xcode support and retention policy to the team and see how we might be better able to support you.
Also with the release of Xcode 26.4.1, it should not have rejected your job requesting Xcode 26.4.0. Instead it should have redirected the job to use xcode 26.4.1. That fix have been made.
Please let us know if you run into any more issues
Hi @fritz-circleci,
Thank you for releasing 26.4.1 so promptly.
Would it also be possible to request macOS 26.4 support on your machine images? Without this upgrade our team are blocked from keeping CI in sync with our local machines.
We use Flutter golden tests in our CI pipeline. When two developers on our team upgraded to macOS 26.4 + Xcode 26.4 locally, the rendering engine produced different outputs than our CI environment. This means our golden tests fail on CI even though they pass locally, or vice versa.
We understand macOS image releases take time to validate, but given Xcode 26.4 is already available, we wanted to flag the demand from our team. Even a beta/preview image we could opt into would unblock us.
Please and thank you
We’re now seeing errors that the 26.4 simulator version is not supported.
xcodebuild: error: Unable to find a device matching the provided destination specifier:
{ platform:iOS Simulator, OS:26.4, name:iPhone 17 Pro }
The requested device could not be found because no available devices matched the request.
...
{ platform:iOS Simulator, arch:arm64, id:FCCA5B06-5EBB-45DB-8A49-F3EE1FE69B1A, OS:26.4.1, name:iPhone 17 Pro }
The software manifest you released for Xcode 26.4.1 (linked here) states that the supported version of simulator is still 26.4. Yet, our builds are saying it’s no longer supported.
Is this yet another forced upgrade? or a temporary issue?
Thanks for reaching out and providing this context about the Flutter golden test issue. I understand how this keep your local machine and CI environments out of sync.
I can confirm that we’re actively working on macOS 26.4 support and have this prioritized in our upcoming image releases. We want to validate that the images meet our stability and compatibility standards before making them available.
While we can’t commit to a specific timeline or guarantee which exact version will be in the next release, I can tell you that macOS 26.4 support is on our near term roadmap given the demand we’re seeing from teams like yours.
@nikhilvm-om That’s strange. Thanks for pointing this out. As you pointed out the 26.4 simulator is definitely present in the image according to the manifest. And the release notes shows its included. We’ll look into this.
