I still have issue with M1. It's almost unusable. Extremely slow and buggy. MacBook Pro 16 M1 Max - 64GB RAM
I can slice one object very very slow but if I have to do any changes after that I have to restart the Cura. sometimes I have to reinstall the Cura completely. Now, the Purse slicer works great with no issue and extremely fast, but I am using Cura for a while and got used to its great features. It has been over 8 months since they promised to come with new version to work with Apple Silicon M1 but nothing yet. Please release the M1 version soon.
