**Building for the M1 (ARM) processor:**
The build steps detailed above should in theory work identically on an M1 processor but possibly some of the dependencies will not build correctly and may need manual patching. Cross-compiling using an Intel processor has been attempted but failed due to multiple issues with depedencies refusing to build. Whenever we'll get access to an M1 Mac the build will be done on this architecture.

**Code signing:**
Due to the Apple notarization requirement implemented as of macOS 10.14.5 a build with simple code signing is needed for versions up to 10.13 and another build with both code signing and notarization is required for version 10.14 and higher.
macOS code signing is beyond the scope of this document, but the option MACOS_CODESIGN_IDENTITY is used to specify the code signing certificate identity, for example:

Assuming the code signing ceritificate is properly setup in Keychain Access, the process will be automatic and the resulting DMG package can be notarized as-is.
Assuming the code signing ceritificate is properly setup in Keychain Access, the process will be automatic and the resulting DMG package can be notarized as-is. For some reason code signing fails if run via an SSH session, so in order for the cpack command to succeed it needs to run from a terminal window started via the GUI.
**Legacy build:**
Normally ES-DE is meant to be built for macOS 10.14 and higher, but a legacy build for earlier operating system versions can be enabled. This has been tested with a minimum version of 10.11. It's unclear if it works with even older macOS versions.

To enable a legacy build, change the CMAKE_OSX_DEPLOYMENT_TARGET variable in CMakeLists.txt from 10.14 to whatever version you would like to build for. This will disable Hardened Runtime if signing is enabled and it will add 'legacy' to the DMG installer file name when running CPack.

You also need to modify es-app/assets/EmulationStation-DE_Info.plist and set the key SMinimumSystemVersion to the version you're building for. And finally CMAKE_OSX_DEPLOYMENT_TARGET needs to be updated in tools/macOS_dependencies_build.sh.

And finally CMAKE_OSX_DEPLOYMENT_TARGET needs to be updated in tools/macOS_dependencies_build.sh. This script then needs to be executed to rebuild all dependencies for the configured macOS version.
Due to issues with getting FFmpeg to compile on some older macOS versions, ES-DE v1.0.1 is the last version where a legacy build has been tested.
As some older macOS releases no longer have valid TLS/SSL certificates and Apple is not providing any updates, ES-DE should be built to use the bundled certificates:
```
cmake -DBUNDLED_CERTS=on .
```

Another issue on macOS 11 Big Sur (and possibly older OS versions) is that when connecting a Sony DualShock 4 controller either via Bluetooth or using a USB cable, two separate controller devices are registered in parallel. This is a bug in either macOS or the DualShock driver and it makes it seem as if ES-DE is registering double button presses when actually two separate controller devices are generating identical input. A workaround if using Bluetooth mode is to plug in the USB cable just after connecting the controller, wait a second or two and then remove the cable again. This will remove the cabled device, leaving only the Bluetooth device active. Another workaround is to enable the setting _Only accept input from first controller_ in the ES-DE input device settings. The reason why this bug may not be visible in some other games and applications is that ES-DE enables and auto-configures all connected controllers. The issue appears to be resolved in macOS Monterey.
In macOS 12 Monterey there has been a quite serious OpenGL driver bug introduced by Apple which disables VSync, making the operating system always try to render as many frames as it can. This slows down ES-DE quite a lot and consumes lots of machine resources. The issue is discussed [here](https://github.com/libsdl-org/SDL/issues/4918). There is a temporary workaround available which can be enabled via the _macOS Monterey VSync bug workaround_ setting in the _Other settings_ menu. This will add a short 10 millisecond delay after each frame if the last frame was swapped in less than 3 milliseconds. It's not a proper fix but it should at least make ES-DE usable on Monterey until Apple releases a patch for the bug.

**macOS Monterey VSync bug workaround** _(macOS only and hopefully only temporary)_
In macOS 12 Monterey an OpenGL driver bug was introduced that causes VSync to always be disabled. This makes the operating system try to render as many frames as it can which slows down ES-DE quite a lot as well as consuming lots of machine resources. By enabling this setting, a small 10 millisecond delay will be introduced after each frame if it took less than 3 milliseconds to swap the last one. This is not a proper solution, and it's not an accurate solution but it's at least something until Apple (hopefully) fixes the bug via an OS update. Earlier macOS versions are unaffected by this issue. To check if you have this problem, enable the _Display GPU statistics overlay_ setting and if your FPS counter shows really high numbers (like in the hundreds of frames per second) then enable this option and the FPS counter should decrease significantly.
