Official Now Available - Native Apple Silicon Editor Preview Builds

The download link has been updated to use a direct link for downloading the Unity.pkg. This should help alleviate any pain experienced around that particular download.

 

Yes, but I can boot Unity back up quicker than a single compile used to take before, so I don't mind them a great amount! Mostly happening to me when a compile is kicked off for an invalid script, like having unfinished lines etc.

 

Firebase SDK not working with ARM Editor (look like firebase not include ARM dll in its sdk)
Anyone have tried using Firebase?

 

My entire 2D game projects works fine upon initial test.
I do have minor hiccups on migrating 2020.3 to 2021.2a19 but easily fixable.
I have few minor crashes/hang on my plugins if they are doing intense stuff.
I experienced a crash while importing a package, but just probably coz my chrome (with couple tabs) is open

 

tbh, the editor hasn't crashed even once for me

 

How is this handling loading native DLL's ?

 

Not sure if its this version's issue, but I'm using new input system and when I press WASD i get system's 'key was pressed, but application didn't know what to do with it or isn't responding' ding sound. On loop, as I hold the button. At same time character does move! I do click game view to make sure its focused.
UPD. Seem to be fine after restart, then it bugs out again after some time.

 

Just a question, why those - Apple Silicon - alpha binaries aren't included for distribution through the Hub? Just wondering...

 

I can locate the Unity 2021.2.0a20 (Alpha) in the Unity Hub... so that version isn't Apple Silicon supported?

 

No its not!

 

Right now native DLLs must be either Apple silicon-only or Universal binaries. We are working on UI for the plugin manager that will let you specify platform as you can for Windows.

 

Right now the only way to get Apple silicon Editor preview builds is through this thread.

That will change in the future. When the Hub does support it, the current plan is to have UI that lets Apple silicon users choose which version to download. I expect that is a few months out.

 

Thanks for your time and keeping us updated like you do, it really does help to plan our works

 

hello,
well many thx for the alpha…
just checked it on my M1 Mini 16GB ram…
new project works… but if i‘ll import my last it crashes when importing PNG‘s…
looks like a memory issues…
well with a new project and export to mobile…
it‘s really fast now… editor too…
way faster as on windows…
Apple ARM … it looks like this will be the killer platform in the future…
way faster as windows …
time for payback hehe
all this cheap cheap hardware user … it sucks…
thx
M.

 

Sprite Editor incredibly slow for no reason when docked.
EDIT:
See this warning spammed:
Internal: JobTempAlloc has allocations that are more than 4 frames old - this is not allowed and likely a leak
EDIT2: Looks like Audio Mixer also has this exact issue. Slow and spamming errors if docked and visible.

 

So with the release of 2021.2.0 beta1, what's the plan for this? Are we going to see further concurrent updates here, or will it be mainlined into a future beta release?

 

We will provide updates periodically. I expect we will have another one early next week. We'll definitely provide updates for any build that has fixes for the known issues linked in the release post above.

 

Thanks to you and your team for the effort.
It brings a lot of value, first time in years that I've seen Unity run this smoothly.

Maybe this was answered already, but do you guys know why compilation/reimport is still significantly slower both in rosetta version and native version?

 

Will this be merged in the regular releases before the beta ends?

 

Did some more testing. First, regular Unity workflow of saving a script, recompiling, building the project is insanely fast.

If you are familiar with UNET, Mirror (or MLAPI I suppose), we do IL Weaving where we modify assemblies after compilation.

Compared to my Macbook Pro 2015 with 2.2 Ghz Intel CPU, this is significantly slower in Apple Silicon Unity Editor:

Regular unit tests are 3.5x faster, which is crazy.
Benchmarks ingame are also 3-4x faster.

Weaving however is 2.5x slower compared to the 6 year old Intel CPU laptop.
We use Mono.Cecil for weaver, which is a managed C# DLL.
From the numbers, it sounds like somewhere in the process some old non-apple-silicon code is being run?

To reproduce, simply download Mirror https://github.com/vis2k/Mirror , open in Unity, run the Weaver tests:

Note that they all pass. It works as expected, it's just significantly slower.

Let me know if there's anything else I can provide.

 

Sure. I'll try to create a more simple repro and see if I notice anything myself too.

 

Is A19 the latest build for Apple Silicon, or is there a beta build available?

 

2021.2.0a19 is the latest Silicon version available. We should(?) be getting a beta version early next week, according to this post.
Now Available - Native Apple Silicon Editor Preview Builds

 

Is anyone else having issues opening existing projects in the native builds? When loading it, I always seem to get stuck on importing. Usually around the "com.unity.collab-proxy" package.

The last thing the Log lists when this happens is :

Code (CSharp):

1. Launching external process: /Applications/Unity/Unity.app/Contents/Tools/UnityShaderCompiler
2. Launched and connected shader compiler UnityShaderCompiler after 0.13 seconds

I'm running on the 2020 MBA Entry model (M1, 8GB RAM, 256GB SSD)

The only way I can get the native editor to load so far, is to use the `-noUpm` flag, which obviously causes compiler errors.

UPDATE: By copying the projects assets into a fresh project folder by folder, I was able to load my project. But after reloading the editor, I get stuck on "Importing (Iteration 2)"

UPDATE 2: This largely seems to be related to prefabs, when the editor gets stuck on reloading, I'm now seeing that its loading my prefabs, and removing the folders with my prefabs in allows the editor to load. Its weird that when the editor is open, Prefabs load correctly

 

We'll get a new build posted in the next few days.

 

Fingers crossed the new version comes out in time for the weekend!

Not sure if this is the known issue WRT lighting baking, but when I try to bake (URP) lightmaps it exponentially increases the ETA, ending up at 20+ minutes after 30 seconds or so. CPU, GPU lightmapper both have the same behaviour. Would be amazing if this was fixed!

 

The first time I tried the currently available a19 editor, I was a bit disappointed since it couldn't even render the URP template's default scene (but maybe I was holding it wrong), but I've now tried opening my current project in it (which also happens to use URP), and it mostly seems to work fine (some small bugs here and there, like certain Start actions not being invoked the first time I entered Play Mode.)

Having said that, the thing I was most eager to try was code compilation/reloading, which isn't great using 2021.2b1 for Intel (on M1), and... holy crap! It was superfast! What was taking around 10-15 seconds in the Intel editor took maybe 3-4 seconds in the native Silicon one. That's super super cool and promising, and I'm now looking forward to future alpha/betas of this (and, of course, the eventual release.)

Thank you & good job!

 

2021.2 beta 2 just released for Intel, awaiting for Apple Silicon

 

Does the page [0] not just include the Apple Silicon editor already, or are my eyes deceiving me? Does this mean we can install it using Hub now?

[0] https://unity3d.com/unity/beta/2021.2.0b2

EDIT: in contrast to below, Hub install fetches an Intel version.

 

Can confirm that the release available here is 2021.2.0b2 for Apple Silicon!


EDIT: It seems that URP requires the Burst Compiler now. Since Burst isn't Apple Silicon ready, URP projects will always have Burst errors

 

Thanks for the new beta! I downloaded the Apple Silicon build directly off the release page. Considering that Unity Hub is still an Intel app, I would not have expected it to be able to auto-detect that it should download and install the Silicon build of the new release.

Running the thing, I'm also seeing errors around Burst, but generally speaking, the beta appears to be working fine with my URP project. I'm mainly seeing errors like this:

Code (csharp):

1. InvalidOperationException: Burst failed to compile the function pointer `Int32 DoGetCSRTrampoline()`

Edit: was even able to generate a universal build for the project, but had to choose "Clean Build" from the dropdown to make it work.

 

2021.2.0b2 has been working great for me on my M1 Air - no more random crashes, super-fast compile times, makes developing fun again - thanks to everyone involved!

 

this beta 2 seems working great for me... no crashes at my side as well

 

Thanks for your patience everyone. I am putting 2021.2.0b2 through the wringer now before I post here with the corresponding list of issues. For those of you that are using the direct download page, please remember that only the builds posted here can be guaranteed to have been put through a minimal test suite as we get everything online. Just keep it in mind.

 

Apple silicon Editor preview 2021.2.0b2 is available to download!

This is a preview build and will have bugs. Please report new issues in the editor by clicking the “Help” menu and selecting “Report a Bug”.

Known Issues

The CPU lightmapper causes the Apple silicon mac editor to crash
Importing an .mp4 or .mov crashes the Apple silicon mac editor

• Workaround: Use universal binaries for native plugins

[iOS] Some files in WebGL and iOS support installers have changed permission from 2021.1.0a2

• Workaround for WebGL: sudo chmod +r /Applications/Unity/PlaybackEngines/WebGLSupport/BuildTools/lib/modules/* as well as sudo chmod +r /Applications/Unity/PlaybackEngines/WebGLSupport/BuildTools/lib/modules_development/*
  
  
• Workaround for iOS: sudo chmod +r /Applications/Unity/PlaybackEngines/iOSSupport/Trampoline/Libraries/*

Download the editor and components for 2021.2.0b2 here.

 

Any idea if/when we'll get updated app icons? It's getting tedious replacing them with every new install to match the rest of the system.

 

After Create New Project, Many errors how to solve that?

 

I see 2021.2b3 is now available. Does the M1 editor still require manual installation, or can we use the Unity Hub installer for it?

 

It still requires manual installation for now.

 

Burst does not yet work with the native Apple silicon editor. I will add it to the list of known issues.

 

Sounds good, thanks for the clarification.

 

All standard packages are missing when trying to create a new project. The only way is to use an older project or download the URP and HDRP demos as starting points. Documentation fails to install. Dollying is broken on ALT+RMB. Will check other stuff later.

Launch performance while better than before is still very poor (though not as poor as Unreal).

It's been a while so apologies if this is been in there for many versions but I'm not a huge fan of docking the "Tools" in the viewport by default. That you can do it isn't necessarily reason to do it unless there's some trailblazing going on, which isn't the case here. It creates the impression of clutter and piecemeal design and adds more content to obscure the UI region you need most clarity within and in which you may wish to develop your own UI.

 

the toolbar changes are new in 2021.2, i wish it was optional. I seriously dislike it.

 

Didn't want to derail this thread in case it wasn't AS specific, but just wanted to drop a link in here as well - is Collab borked in the AS 2021.2 beta, or is it broken in this version in general?

https://forum.unity.com/threads/is-collab-broken.1138417/

 

Is there any way to turn off the burst compiler to not seeing errors?

 

when I edit on player setting this is what happen i can not edit Player setting anymore even if i restart editor
