We have released an Xcode 11 Beta 6 image today. You can select the image by adding the following to a job in config.yml :

```auto
macos:
  xcode: 11.0.0

```

The main change in this image compared to the beta 5 image is the version of Xcode:

- Xcode is now version 11.0 **Beta 6** Version `11M392q`
- Since this is a beta image, we have a reduced set of simulators, all running iOS 13. We will add more simulators to the final image.

Minor changes:

- NodeJS was upgraded 12.6.0 -\> 12.8.1
- git upgraded from 2.22.0\_1 to 2.23.0

The full manifest of the installed software and SDKs is available [here](https://circle-macos-docs.s3.amazonaws.com/image-manifest/build-999/index.html).

## Known issues

- There is an issue where a dialog appears for the first 30 seconds after the image boots reporting that the OS did not shut down cleanly on the last boot. This might impact UI tests. We pre-boot VMs so that builds can start as quickly as possible, so in many cases our VMs have been booted more than 30 seconds prior before to build running, which will reduce the rate of occurrence of this bug.

## Upcoming deprecations / changes

- [Removing support for Xcode 10.2.0 on Monday, August 26th, 2019](https://discuss.circleci.com/t/removing-support-for-xcode-9-1-and-10-2-0/31542). This version has [bugs that we fixed](https://discuss.circleci.com/t/xcode-10-2-image-released/29761/5) in the Xcode 10.2.1 image. After August 26th all jobs using Xcode 10.2.0 will automatically use Xcode 10.2.1. There might be differences in the dependency versions between the Xcode 10.2.0 image and the Xcode 10.2.1 image. Please upgrade to **Xcode 10.2.1** or newer.
- [Python 2 will be no longer be maintained](https://www.python.org/dev/peps/pep-0373/) from January 2020. We plan on removing Python 2 from any images built after that date (Python 2 is being removed from `homebrew`).
