I will admit all these multitasking will reflect inaccuracy BUT Windows &amp; Mac don't get file copy right no matter how straight forward.... and both can be out from saying minutes to hours and being wrong by each... eg: this will take 3 minutes, but actually takes 45, or this will take 5 hours... and one minute later it's done. wrong wrong wrong wrong wrong.... all my years since the beginning of the 90's. 😵😵‍💫😢🤬
