Question

Is there a way to build a universal pkg Intel + ARM64 for Mac That is needed to be able to upload it to the Apple AppStore

Alexander Kurasov[JB] · Answer

You can try to add both MacOS dependencies instead of ```implementation compose desktop currentOs ``` use ```implementation compose desktop macos arm64 implementation compose desktop macos x64 ``` In my undestanding it should include both platform binaries into the bundle

Thanks I gave it a try but when doing a right click and get info on the produced ` app` it still shows `Apple Silicon` instead of `Universal` I am building the project on an M1 Mac with an ARM64 JDK I am not sure what to do about the bundled JRE Would I need to include it twice for Intel and for ARM64 or so

That is a good question Could I ask you to create an issue on github since the topic seems to be an important one

Thomas · Answer

Sure Should I create a single issue for all Apple AppStore related issues and feature requests

Thomas · Answer

I noticed some stuff that is missing in the jpackage task etc

Let s start with a single issue We can always split it later

< Thomas> how far did you get with this it would be great to not have to switch between an M1 and an Intel mac just to build two different builds of our CfD applications I also noticed this issue which appears stale and I am wondering if there is some way we can contribute cc < Igor Demin>

Have not looked further into this yet For now I am just uploading an Intel only build I think the solution would be 1 build a universal intel arm64 jar 2 merge intel arm64 JREs into one JRE at build time

Thomas · Answer

For now I am quite busy with Windows but I plan to pick up the macOS issues in the coming months

Thomas · Answer

There is an open issue about universal Mac build here <https github com JetBrains compose jb issues 1599>

Thomas · Answer

Unfortunately it is not as easy as just building a universal jar as the jre is not universal

Thomas · Answer

< james> if you have any ideas please share them

Thomas · Answer

To build a universal JRE I think the way to go would be to use `jlink` twice One time with an Arm64 JDK second time with an Intel JDK Then you have two JREs Must be the exact same JDK version Then merge the JREs manually using the Apple tools for this into a universal JDK Then pass that universal JDK to `jpackage` At least that is what I am going to try when I look into it again
