I have a lot of data and I often find myself copying massive amounts of data from one drive to another. Sometimes during this process, a copy will go bad and will stop. For whatever reason, after I get back to the Finder on my Mac the folder I was attempting to copy is grayed out and inaccessible. It’s very annoying, especially if I’ve copied 700GB of 1.1TB as I don’t want to start the copy process all over again.
What happened? Well, your Mac knows something went wrong so it sets the date the Macintosh was first introduced, January 24, 1984.
So how do you fix the problem?
Change the date of the folder to today or something more reasonable than 1984.
I found two ways to do this after a few searches online.
The first is to use XCode which I’ve found to be the most reliable but it does require you download XCode from the App Store. If you’ve already got it installed, even better.
Run this command, choose a date
SetFile -d 29/08/2014 /Path/to/grayed-out-folder/
Now the folder should be normal and accessible. (You may need to close the Finder window navigate back to it again.)
But if you don’t want to download and XCode you can do try a few other things.
I saw online, you could try change the date by
touch -t 201408291100 /Path/to/grayed-out-folder/
This should change the date, however when I tried to do this it didn’t change the folder as it was still grayed out and inaccessible.
Another approach without XCode is to make a new folder and then move the contents of the grayed out folder into it.
Using the Terminal, go to the root location of the grayed out folder. If the grayed out folder is at /Path/to/grayed-out-folder/, then the root would be /Path/to/
cd /Path/to/ mkdir newdirectory mv grayed-out-folder/* newdirectory/
Hopefully this saves you some time.
