# 🚀 Ultralytics v8.4.163: Export Apple Core AI Models from Linux

**Quick overview:** Ultralytics YOLO can now export Apple Core AI `.aimodel` files on x86\_64 Linux, making cloud servers and CI workflows useful for preparing models for Apple devices. This release also improves export reliability and trims Docker images.

## 🍎 New Feature: Core AI Export on Linux

Export `.aimodel` files on x86\_64 Linux or on Apple silicon Macs running macOS 26 or later. The exported models target iOS 27 and macOS 27; **running them still requires Apple hardware**. Core ML remains a separate export option. See the [Linux Core AI export PR](https://github.com/ultralytics/ultralytics/pull/26333) by @glenn-jocher.

## 🔧 Improvements and Fixes

- **Updated compatibility:** Support for `coreai-torch` 0.4.3 brings conversion-time optimization and Python 3.11–3.14 support. [Compatibility PR](https://github.com/ultralytics/ultralytics/pull/26327) by @cdeil.
- **Clearer benchmarks:** Linux can report Core AI export results while correctly skipping inference, which requires macOS. [Export and Docker PR](https://github.com/ultralytics/ultralytics/pull/26326) by @glenn-jocher.
- **Safer failed exports:** PyTorch functions patched for certain ONNX exports are restored even if export fails, avoiding unexpected effects later in the same process. [Reliability PR](https://github.com/ultralytics/ultralytics/pull/26325) by @Nikhi00718.
- **Leaner Docker images:** Builds no longer retain package-install caches or bundled PyTorch test files, while keeping needed runtime tools. [Export and Docker PR](https://github.com/ultralytics/ultralytics/pull/26326) by @glenn-jocher.
