Hi, i'm planning on buying an m1 iMac with 256gb storage, 8gb ram and the 7 core gpu. Will this configuration be enough for Xcode development, Create ML and swift playgrounds? Thanks in advance :)

I have hundreds of thousands of image files that are cropped images grouped into class folders appropriately that I would like to use in Create ML to training an object detection model. I do not have .json annotation files for any of those cropped images. Q1: Am I required to create the .json annotation file for each individual image and just set the bounding box coordinates to the four corners of the images since the full image is the object already cropped? Or is there a way to leverage what I have directly without creating all those .json files? Q2: Anyone have a handy script to help automated the creation of those files? :-) Thanks everyone.
