[MC-224481] Game not optimized for Apple M1

Found no issue relating to this and as far as I know it's a pretty simple issue to fix. Minecraft (the game itself, not the launcher, that doesn't matter much) runs as an Intel app through Apple's translator on the M1 Macs, and this causes a huge performance hit. Using this launcher script (which doesn't modify the game, just allows it to launch without Apple's emulator) the game launches over 3x slower and has noticeably worse performance, from loading worlds slower to a way lower framerate than when playing the game with the native launcher script.

Sorry, please ignore the bot, it erroneously thought the GitHub Gist link contains sensitive information.
I will make this report public again.

Ah, thanks for fixing that

Bo Chang 2021-11-19T11:37:55Z

I look forward to supporting native arm one day

Leonov 2021-11-19T19:03:19Z

They don't really care about Mac in general so... I won't set my expectation too high.

I mean :
Confirmation Status: Plausible
What, it's only « plausible » that Apple switched to a different architecture?

Lucas 2021-11-20T11:06:58Z

I don't understand it either… Apple is switching to a different architecture and Rosetta 2 won't exist forever…

There's an ARM Java-version and the dependencies of the launcher are Apple Silicon-ready as well, as far as I know.

Additionally, the launcher won't even open on the newest macOS version (you need to run a terminal command to avoid the auto-update of the launcher), soooooo … I would say, this is a pretty terrible situation for any Mac user playing Minecraft.

Lucas 2021-11-20T11:59:54Z

An addition: This report should include all Minecraft versions (or at least the newest version 1.17.1 and not just a snapshot), because 1.17 is not M1/ Apple silicon native either.

Leonov 2021-11-20T12:12:37Z

I'm not exactly sure on how they do it, but since Mojang bundle their Java into the game, all versions should update at the same time.

Lucas 2021-11-20T19:15:06Z

That would be great! And that doesn't sound like too much work since there is already an ARM version of Java for Mac.

I hope Mojang does this soon…

Also, the confirmation status is now "Community Consensus". Hope this speeds things up…

To clarify, this is possible.

I had to download an Apple native version of LWJGL (and using an aarch64 build of Java, of course, which is available since Java 17 on all platforms) and launch it with:

-Dorg.lwjgl.librarypath=/Users/chew/Downloads/1.17-m1-multimc/lwjglnatives/ -Dfml.earlyprogresswindow=false

Once I did that, it ran through it fine:

So this is less of a library issue than actual Java code (running any java program with an aarch64 build of Java will automatically make it native)

Lucas 2021-11-22T08:37:45Z

I'm sure Mojang also knows that this is possible. If players can do this themselves with a little downloading and a terminal command, this shouldn't be too much work for them.

Maybe making the Minecraft Launcher Apple Silicon native is a little more work than just using an aarch64 version of Java, but this is also totally possible.

Nonetheless, I hope that there is an "official", out-of-the-box solution for this issue soon…

Bo Chang 2021-11-22T12:30:16Z

@Chew Can you elaborate on the installation steps? I don't understand the code at all.

Lucas 2021-12-18T09:41:09Z

I hope there is a "out of the box" solution soon… I don't want to install third party-launchers or mess with the code…

Please, Mojang!

Machiel van Dorst 2022-02-25T14:13:19Z

It would be so simple to fix this. A recompile of the very small launcher app and the inclusion of a Java runtime that's AS native. Please Mojang

Leonov 2022-02-26T08:10:37Z

So I gave a link to a open source project that is a simple launcher that does the job and the comment is removed? Mac Players : Google M1Craft.

Moesh 2022-03-02T08:09:05Z

Minecraft: Java Edition does not officially support Mac M1s.

Leonov 2022-03-02T09:31:59Z

That was an easy fix.

Neil Brewitt 2022-03-02T09:57:52Z

This has not been resolved, but at least we now know the correct title of the new defect report.

Raised as MC-248874

Leonov 2022-03-02T10:11:22Z

The worst part is, that in order to resolved this, Mojang has almost nothing to do.

Einfxch_Finn 2022-03-02T10:15:43Z

They just need to update lwjgl to version 3.3.1 and the Java-Objective-C-bridge to version 1.1 and then it would run completely native on M1.

Neil Brewitt 2022-03-02T11:43:12Z

It seems like the best way to encourage Mojang to address this might be to upvote this.

Joseph Bruni 2022-04-15T21:17:01Z

I've looked for other issues opened related to running natively on Apple Silicon and this issue seems to be the best written. How do we get this issue re-opened so that MC can run natively on ARM?

Leonov 2022-04-16T19:00:56Z

They don't want to support M1, apparently, so it's not a bug and it can't be reopened.

user-f2760 2022-04-16T19:14:13Z

Something not being supported is not a bug, whether they want to or not. Lack of feature is not a bug.

Joseph Bruni 2022-04-21T23:24:13Z

That other feedback "Native M1 build" is for bedrock. I'm just looking to get MC Java to run on the ARM version of the JRE so that I don't need to use Rosetta2 to emulate intel to run the JRE. The Java version of MC is fine.

Leonov 2022-04-22T07:05:30Z

Search for « M1craft ». I can't post a link, apparently. My comment about that project was deleted. It's a good solution while waiting for Mojang.
