Progress bar window didn't appear when copying
Hello,
I copied a 500GB file from the internal HDD (Fusion Drive) to an external drive (Finder windows drag and drop). Surprizingly the small window which normally shows the copying progress didn't appear, but it seems the file got copied after some hours. Because of the missing progress bar, I couldn't cancel (x) the process. I never ever saw something like that! Why did this happen? Because of this irregularity, could it be that the copied file is defective? (it was meant to be a backup)
Thank you.
