IL2CPP Mac OSX requires macOS 11 SDK

I want IL2CPP builds for Mac OSX and Windows (I know Windows is coming soon! And I hope "soon" is not too far away otherwise I'll have to switch to another CI provider).

However Mac IL2CPP is advertised as working and using Unity 2020.2.1f1 I'm currently getting this error:

ERROR: Error building Player: IL2CPP scripting backend requires macOS 11 SDK (Xcode 12.2) or newer to be installed when targeting Apple silicon devices. Currently installed macOS SDK version is 10.15.4.

Is there an ETA for when the macOS SDK will be upgraded?

Really happy with UCB, it fit my needs perfectly, you guys did a great job! But being blocked with no IL2CPP on desktop builds means I'll have to switch...

 

Argh. So the problem we have there is that we currently have two separate buildbot images - one on Mojave and one on Catalina. We're forcing all builds that want to use Xcode 11.7+ across to Catalina (since otherwise that doesn't work) and all 32-bit Unity versions across to Mojave (since Catalina drops support for 32bit executables). However we don't actually have a mechanism for determining that you're using IL2CPP and swapping on that basis.

I guess as a temporary workaround if you submit a support ticket we can force all your builds to land on Catalina builders but I'll have to discuss this issue with the team and try to figure out a more general approach.

 

I just talked to the Mac platform team and they indicated that this limitation comes from building for Apple silicon, which is currently only supported in 2020.2+. I'll add some code to limit OSX builds on those Unity versions to only run on Catalina.

 

That sounds great! Thank you very much!

 

Hy,

i have the exact same issue as Starbust999

"Error building Player: IL2CPP scripting backend requires macOS 11 SDK (Xcode 12.2) or newer to be installed when targeting Apple silicon devices. Currently installed macOS SDK version is 10.15.4."

"Error building Player: Currently selected scripting backend (IL2CPP) is not installed."

any eta when unity cloud build will be fixed for this? just started to use UCB but so far i am not able to build the most important clients for my project :/

Kind regards

 

Yeah the deploy for this fix got derailed a bit since we were prioritizing the Cocoapods issues, I'll try to get this out today.

 

Just deployed this, let me know if you're still running into issues.

 

Just tried and still getting

Code (CSharp):

1. [Unity] ERROR: Error building Player: IL2CPP scripting backend requires macOS 11 SDK (Xcode 12.2) or newer to be installed when targeting Apple silicon devices. Currently installed macOS SDK version is 10.15.4.
2. 80: [Unity] Error building Player: IL2CPP scripting backend requires macOS 11 SDK (Xcode 12.2) or newer to be installed when targeting Apple silicon devices. Currently installed macOS SDK version is 10.15.4.

Unity Version: Unity 2020.2.1f1

 

i have honestly dropped the subscription directly again and wrote my own build server system with 2 machines and the unity cli. More expensive as i had to buy the machines, but less trouble and not having to rely on vms.
as much as i like unity and love to work with it, but this cloud system is in a pretty bad state for a system which was introduced over 3 years ago.

my jenkins+agent system running on 2 intel nucs with windows and macos does the job just fine now.

 

Still getting:

Code (CSharp):

1. [Unity] ERROR: Error building Player: IL2CPP scripting backend requires macOS 11 SDK (Xcode 12.2) or newer to be installed when targeting Apple silicon devices. Currently installed macOS SDK version is 10.15.4.
2. [Unity] Error building Player: IL2CPP scripting backend requires macOS 11 SDK (Xcode 12.2) or newer to be installed when targeting Apple silicon devices. Currently installed macOS SDK version is 10.15.4.

 

I am also having this issue

 

you should consider setting up your own build system as i did. i do not expect a lot to happen here. if something is stagnating for over 2 years, it means the product is pretty low in priority and won't be supported as much as the community would like to see.

 

@victorw IL2CPP build compilation with 2020.2 are now working! Thank you!

However I seem to have notarization issue on my 2020 build but that's a separate issue (I think it has to do with application specific password being removed by apple since this February, any plan to support App Store Connect API Key?)

 

@victorw Hey I'm still unable to build IL2CPP for Mac and getting a different issue. I tried compiling with 2020.2.6 and 2020.2.7. I'm compiling from Big Sur 11.2.2, latest Xcode installed, but the compiler errors out with the message below. I have no issues using Mono but I've been unable to compile to IL2CPP for mac for nearly 18 months now, it'd be great to get this working.

Hey @victorw could we please get an update on this?

I myself have been having this issue for months. This topic seems to have had no response from you since January... its now near the end of April, 3 months later with no response on the matter.

Some screenshots showing the same issue (both with "intel + silicon" and "intel"):
(And yes, I have Xcode installed and up-to-date)

 

For anyone still with this issue, I got an email from Unity this morning which helped me solve this.

Here is the portion of the email which helps fix said issue:

""
It seems that Unity doesn't detect the Xcode SDK installation. Perhaps you could try running the following command in the Terminal window:
'sudo xcode-select --reset' or if that doesn't help 'sudo xcode-select --install'

You might also need to reboot your Mac afterward.
""

I tried this, and it worked. Happy once again

 

@ShaneBeee, that worked for me! Thanks you so much

 

Hello, it's the end of 2022 and this is still an issue as of 2021.3.5f1
Using MacOS 12.6
I have Xcode installed latest version and MacOS SDK as well...
This is getting frustrating

 

It asked for xcode 12 I believe
Although I have 14 installed

error is gone now and I haven’t touched a thing… can build with IL2CPP … so odd

 

Delete XCode and reinstall
it worked.

 

I am using Unity 2021.3.34 and Mac Os Sonoma 14.3 and XCode 15.2 and unity keeps sending me this message:

Code (CSharp):

1. Error building Player: IL2CPP scripting backend requires macOS 11 SDK (Xcode 12.2) or newer to be installed when targeting Apple silicon devices. Currently installed macOS SDK version is 10.15.6.

 

did you try the suggestion a few comments up to refresh the xcode pointer to the sdk installation?

 

This is still an error in 2022
