Update on Xcode for Mac 10.12.6 and Unity Editor Interoperability Issues

Are you experiencing issues with Xcode on Mac OS 10.12.6, particularly with Project View items disappearing? You're not alone. Our team has been working tirelessly to resolve this problem, which we believe is linked to APFS (Apple File System) and Unity editor interoperability.

To provide a workaround for the missing assets issue in Project View, we recommend disabling networking while opening your project. This should help alleviate the frustration caused by the problem. However, please note that this fix may not be effective for everyone, so we'll continue to monitor the situation and update this post as we learn more.

Additionally, we've identified a global cross-platform Unity Editor outage issue when opening projects on Mac OS 10.12.6. To address this, you can try disabling networking while opening your project.

While Xcode 9 works seamlessly with macOS 10.12.6, we advise developers in the final stages of game development to remain on the older operating system to avoid any potential issues. For those using Unity 5.4.x and earlier versions, it's recommended that you consider upgrading to Unity 5.5.x or later to ensure compatibility with the latest macOS version.

For those who need to continue using older Unity versions on HFS+ disk, we recommend considering it as a last resort workaround. Unfortunately, there will be no further support for Unity 5.4.x on High Sierra (macOS 10.13), and you'll need to either keep your machines on macOS 10.12 or upgrade your project to Unity 5.5.x or later.

For those encountering issues with Monodevelop on macOS 10.13, we recommend manually installing Visual Studio for Mac and using it for script editing. These versions include multiple fixes for disappearing assets on APFS, Unity Editor crashes, and Monodevelop crashes.

In summary, if you're experiencing issues with Xcode or Unity Editor on Mac OS 10.12.6 or macOS 10.13 (High Sierra), we recommend disabling networking while opening your project, upgrading to Unity 5.5.x or later, and considering the use of Visual Studio for Mac for script editing.

We'll continue to monitor the situation and provide updates as more information becomes available. Thank you for your patience and understanding.
