I saw that there had been no movement on this issue ([Feature request: Support MacOS ARM · Issue #261 · openrndr/openrndr · GitHub](https://github.com/openrndr/openrndr/issues/261))about M1 support, but it looked like, since there does exist a LWJGL version that supports the M1, this could be an easy change to do my self. However, I was looking at the template project, and I am new to the Gradle build system and couldn’t find where the dependencies are listed. Is there an easy way to locally bump the LWJGL version to get OPENRNDR to run on an M1 mac?

Hi hi ! Welcome to the forum 🙂

Have you tried with the 0.4 branch?

To try you can do this:

```auto
# build latest openrndr and publish to local maven
git clone https://github.com/openrndr/openrndr
cd openrndr
./gradlew publishToMavenLocal -Prelease.version=0.5.1-SNAPSHOT
cd ..

# build latest orx and publish to local maven
git clone https://github.com/openrndr/orx
cd orx
./gradlew publishToMavenLocal -Prelease.version=0.5.1-SNAPSHOT
cd ..

# clone 0.4 branchn of the template, which uses local maven snapshots by default
git clone https://github.com/openrndr/openrndr-template.git
cd openrndr-template
git checkout openrndr-0.4

```

Thanks for the tip! Unfortunately this is the output I get from trying to build openrnder

it seems related to this issue in Kotlin Multiplatform, but again, I’m not sure how to go in and change the relevant configurations to update the reference to the node.js version - [https://youtrack.jetbrains.com/issue/KT-49109](https://youtrack.jetbrains.com/issue/KT-49109)

So until Kotlin 1.6.20 is released, a workaround seems to be adding

```auto
rootProject.plugins.withType<org.jetbrains.kotlin.gradle.targets.js.nodejs.NodeJsRootPlugin> {
    rootProject.the<org.jetbrains.kotlin.gradle.targets.js.nodejs.NodeJsRootExtension>().nodeVersion = "16.0.0"
}

```

into `settings.gradle` in `openrndr`. The issue is that the code above is written in Kotlin (kts) syntax, but `openrndr` so far uses Groovy. Do you know how to write the above in Groovy?

I can give it a try but unfortunately i’m not exactly sure what this code means syntactically in kotlin either (it’s my first time picking up both kotlin and gradle). I found this [Migrating build logic from Groovy to Kotlin](https://docs.gradle.org/current/userguide/migrating_from_groovy_to_kotlin_dsl.html) to help, but nothing yet to assist specifically in the kotlin =\> groovy direction

Maybe [this Chinese website](https://book.kotlincn.net/text/js-project-setup.html) shows how to do it?

```auto
// settings.gradle in openrndr
rootProject.plugins.withType(org.jetbrains.kotlin.gradle.targets.js.nodejs.NodeJsRootPlugin) {

```

Update: in the YouTrack link above they suggested this alternative:

```auto
rootProject.plugins.withType(Class.forName("org.jetbrains.kotlin.gradle.targets.js.nodejs.NodeJsRootPlugin")) {
    rootProject.extensions.getByType(org.jetbrains.kotlin.gradle.targets.js.nodejs.NodeJsRootExtension.class).nodeVersion = "16.0.0"

(I think i might just wait for Kotlin 1.6.20 to be release, which i think will have a built in update to the node.js version, just leaving the current state of things in case it’s helpful to anyone else)

Yup - initially had the `plugins` line at the end, and tried with the `plugins` statement after the first line, same issue

I managed to make it work !

A bit complicated but here are the steps :

First, following Abe’s comment clone the openrndr and orx projects.

* * *

In the openrndr project

- according to what was said on the slack, copy the changes made in the project : [https://github.com/openrndr/openrndr/compare/master...ink404:m1-support](https://github.com/openrndr/openrndr/compare/master...ink404:m1-support)

- in `openrndr`'s **build.gradle** (not settings) set the node version. _I added this after the plugin declaration but I’m not sure that matters._

```auto
rootProject.plugins.withType(org.jetbrains.kotlin.gradle.targets.js.nodejs.NodeJsRootPlugin) {
	rootProject.kotlinNodeJs.nodeVersion = "16.0.0"
}

```

- build it locally : `./gradlew -Prelease.version=0.5.1-SNAPSHOT publishToMavenLocal`

* * *

In the orx project

- in the **build.gradle** set node version

```auto
rootProject.plugins.withType(org.jetbrains.kotlin.gradle.targets.js.nodejs.NodeJsRootPlugin) {
    rootProject.kotlinNodeJs.nodeVersion = "16.0.0"
}

```

- Make sure `openrndrVersion` is set to `0.5.1-SNAPSHOT` and then build it like : `./gradlew -Prelease.version=0.5.1-SNAPSHOT publishToMavenLocal`

* * *

In the openrndr-template on the master branch:

- change the `openrndrVersion`, `orxVersion` and `ormlVersion` to the `0.5.1-SNAPSHOT`
- add `maven(url="https://oss.sonatype.org/content/repositories/snapshots/")` in repositories.
- On the command line run `./gradlew build` and then `./gradlew run` or use the main function’s green arrow and it works!

Hope this helps

Amazing! this did it! a couple notes:

For those reading later, for the `openrndr-template` changes, the maven repository needs to be done in `settings.gradle.kts`.

Also in that file, i had to set `openrndrUseSnapshot = true` and `orxUseSnapshot = true` - otherwise, the `openrndr-template` project would build, but the TemplateProgram would not run.

Thank you so much for the help!

Very nice that you made it work! I find it a bit odd to change `lwjglVersion` because master is already using 3.3.0, and `3.3.0-SNAPSHOT` was needed before 3.3.0 was released. Could you try keeping it at

```
lwjglVersion = '3.3.0'

```

and not adding

```
maven { url "https://oss.sonatype.org/content/repositories/snapshots/" }

```

? Maybe it works still? Just wondering what’s the minimum change required… 🙂

Yep it works well with keeping lwjglVersion at 3.3.0 and staying with mavenCentral.

But now the issue I have is when trying to use the camera this error is thrown :

```auto

It seems org.bytedeco haven’t released a Mac m1 version of ffmpeg yet…

</div>

That sounds more tricky to solve… Either waiting or building your own ffmpeg? No idea where to start with that…

Going back to the steps required to make it work: I wonder if the other two changes from [https://github.com/openrndr/openrndr/compare/master...ink404:m1-support](https://github.com/openrndr/openrndr/compare/master...ink404:m1-support) are required? because they are changing the plain macos version, not the macos-arm64… Could it be that the only thing needed was updating the nodejs version in two files? If that’s the case then we can post a solution (either here or updating the actual source, so it just works… except ffmpeg for now).

Those changes seem needed, if I leave `native-macos` instead of changing it to `native-macos-arm64`, running the simple template throws:

```auto

```

For ffmpeg in some articles they talk about adding `ffmpeg-platform` as dependency. I also saw that `org.bytedeco.javacpp:1.5.6` starts introducing jars for macOS-arm64. I’ll give it a try later.

</div>

Managed to make the camera work!  
To do so I needed to install ffmpeg on my Mac.

```bash
brew install ffmpeg

```

Then I had to bump ffmpeg in openrndr’s `build.gradle` to use the 5.0-1.5.7.

line 50-51:

```bash
    javacpp_version = '1.5.7'
    ffmpeg_version = "5.0-$javacpp_version"

```

Then change `openrndr-jvm/openrndr-ffmpeg-natives-macos/build.gradle` to use the arm64 version of the jars.

```nohighlight
dependencies {
    runtimeOnly "org.bytedeco:ffmpeg:$ffmpeg_version:macosx-arm64"
    runtimeOnly "org.bytedeco:javacpp:$javacpp_version:macosx-arm64"
}

```

Due to moving to version 5.0, in `openrndr-jvm/openrndr-ffmpeg/src/main/kotlin/org/openrndr/ffmpeg` some functions used In `AudioDecoder.kt` and `VideoDecoder.kt` became deprecated and needs to be changed.  
I didn’t actually try the audio functionalities, so I’m not sure the following changes are good, but at least it compiles :  
AudioDecoder.kt:123 :

```kotlin
// Replace the following line
// val size = avcodec_decode_audio4(audioCodecContext, audioFrame, frameFinished, packet)
// With the next one
var ret = avcodec.avcodec_send_packet(audioCodecContext, packet)

```

AudioDecoder.kt:183 :

```kotlin
// Change
// val buffer = av_buffer_alloc(audioFrameSize)!!
// To
val buffer = av_buffer_alloc(audioFrameSize.toLong())!!

```

VideoDecoder.kt:141

```kotlin
// Change
// val buffer = av_buffer_alloc(scaledFrameSize)!!
// To
val buffer = av_buffer_alloc(scaledFrameSize.toLong()())!!

```

Recompile the whole thing and it should work!

Also make make sure you run the program through IntelliJ and not command line. If you run gradle through command line the Mac is not going to ask for the camera permissions and if it doesn’t have this permission it will crash.
