![]() I do not have earlier versions installed. We will continue to update this page as further information becomesĪs I recall (and I have been using Mathematica on Macs since version 1.1), this is the first time that there has ever been such a disconnect.Īfter installing the final release version of macOS 11 (Big Sur), I find no problems at all with Mathematica 12.1.1. To ensure that you will be able to use your Wolfram product, please We are committed to ensuring that Wolfram product versions releasedĪfter macOS 11 will be fully compatible with macOS 11. Previous versions of our products will be compatible with the released Wolfram Research cannot guarantee that any ![]() Wolfram software designed for earlier versions of macOS may notįunction on macOS 11. Will my Wolfram desktop product be compatible with macOS 11 Big Sur? There is a FAQ on the Wolfram site that Mathematica 12.1.1 and earlier are not supported on macOS 11. ![]() I am already getting Universal apps from third party developers. I see that the most recent beta I have is still Intel, and not universal, but that could change before 12.2 is released. I will probably wait to buy new hardware until there is a native version of Mathematica. My guess is that anything before 12.2 is going to run in emulation - not terrible, since benchmarks indicate that the emulator is still very fast. It seemed, to me at least, that we were to infer that older versions would not be supported - a bit negative, as things turned out.Īs for the Apple Silicon, it would be good for us to know what was going to run 'natively' and what was going to use Rosetta II. The previous FAQ, perhaps, could have been more explicit that you (Wolfram) just needed more testing. I see that the FAQ page has been updated to provide more information about macOS 11 and Mathematica with Intel processors. I'm sure I missed stuff in my beta testing. Mathematica is now so complex that it is really difficult to validate new versions, especially when there are major changes to the OS. Once we do, we'll release it to pre-release testers. We don't have anything ready to show the outside world. Because of the nature of the Rosetta technology, while we don't necessarily need to port every single piece at once, we do need to port some large pieces all together (for example, all LibraryLink paclets together with the Kernel). As you note, Mathematica is a large and complex application, so the porting process is not as simple as just checking a box in Xcode. We've been working on a native port for a while now. I'm cautiously optimistic that running under Rosetta will not be significantly different than running on Big Sur Intel, but until we have the final hardware and software in hand to do a validation test, we can't give any assurances at all. If there are additional issues in running on Apple Silicon, we will do our best provide workarounds. Again, we've not yet had the chance to run the full test suite with production hardware and software. Rosetta does not emulate certain newer instructions (AVX, AVX2, and AVX512), but it emulates a slightly older Intel CPU well enough that MKL can't tell the difference and gives good performance.Ĭertainly 12.0 and 12.1 will be using Rosetta. Workarounds include turning off antialiasing, as well as going into the options inspector changing 3DRenderingEngine to OpenGL instead of Metal.Īnd about MKL specifically, it runs quite will on the M1 Mac. If you use transparency in Graphics3D, bad things will happen. Thus far, the only issue we've found is with Metal. We are running the full QA validation suite on a real M1 Mac as I write this. As for when the native port will be available, I can't say definitively when, but this will not be like the Cocoa port that took years to finish. ![]() I'll leave that as a little Easter egg for folk to find. However, if you know where to look (very carefully), it does know whether it is running on Apple Silicon or an Intel CPU. There just wasn't enough bandwith the finish all the new cross-platform features and put together a polished ARM port. So now that 12.2 is out in the wild, I can be a bit more specific.
