Apple M1 support

Hello,

I'm the happy owner of an Original Prusa i3 MK3S and an Apple Mac mini with the M1 CPU. Yesterday I tried to slice a pretty complex 3D object created in Blender and used the latest PrusaSlicer 2.3.0. The slicing of the object was impossible, I could not rotate or zoom or do anything once I pressed the slice button in the Application. Big Sure identifies PrusaSlicer as Intel architecture and given the fact that my late 2009 iMac i7  could easily handle the object in Prusaslicer I understand that it is definitely a compatibility issue with the Apple CPU architecture.

My question, and excuse me if this is already mentioned somewhere if it is I couldn't find it, should we be expecting an Apple CPU compatible slicer and by when?

br,

https://github.com/prusa3d/PrusaSlicer/issues/5754   

There are a few more related ones on Github too.  So probably at some point but the date is unknown.  I suspect that no one at Prusa has a Mac with that hardware as yet either so official builds may take a bit longer to appear.

RE: Apple M1 support

Running a new Mac Mini M1 and installed Prusaslicer. I suppose it is now running via Rosetta 2. It works OK except for the fact that when adding modifiers or items I cannot resize these using exact measurements in the right table (Expert mode). Using the resize option from the left menu is not accurate enough. Did not notice this before the upgrade to the M1. Any suggestions?

RE: Apple M1 support

There’s an open issue regarding that on GitHub and it’s got nothing to do with the m1.

I'm also on an M1 with no issues...Or at least no unique issues related to just the M1.  It basically functions exactly as it did with my old intel i9.

For simple mechanical items i see no difference to my old i7. still when it comes to slice more complex items the difference in time is significant in favour of the i7 which makes no sense. I cross fingers for a native PrusaSliser version  (and some drawing apps like fusion and blender) in he next couple of months if not earlier... This tweet posted above made me hope again for PrusaSlicer 🙂

I switched from a 2011 MBP15 i7 to the M1 MBP and was pretty underwhelmed with PrusaSlicer. I mean I had some nasty issues with the latest 2.3 Version, probably also due to to defect ATI graphic which are now of course gone (not showing the finished sliced view of medium large/complex objects and completely crashing with large ones). but it isn't really a lot faster now. 

 

I really was hoping for a lot more improvements in slicing speed and still do for M1 Version to come. With a 30x30x40 Printer slicing of large prints just takes ages ...
