Hi. I'm new to Mac OS with a retina MacBook Pro. I'm finding the OS to be incredibly crappy copy large quantities of files. I'm doing some photo management. Copying 3,000 or so files from an SD card to the local HD. Do some management (editing, renaming, etc). Then copying those same files to a Synology NAS. I do the copy with a command-A and then drag/drop. I find that the copy window pops up, it goes in to "prepare to copy" mode for an incredibly long time, never really gives a good indication of progress. It does always finish after what I think it way too long of a time. It just feels like the OS is kludgy when moving around large quantities of files. Is this normal? Windows was much more robust for these purposes, especially the new file copy dialogs and features in Windows 8. I hope Apple takes some initiative to improve this element of their OS.
