Problem: The project xxx has been used by OS X and cannot be opened.
My computer is macOS. Recently I downloaded some jpg and png images to the hard disk (Seagate hard disk) and switched them to another computer, the results show that the jpg and png images are gray and cannot be opened.
Solution:
Because these files are added with extended attributes by the system, we only need to delete these attributes,
The specific usage is:
$ Cd your file directory
View the attributes of all files in the current directory
$ Ls-l
Note that the last character in the red box is @, so we need to delete it.
Deletes the extended attributes of all png files in the current directory.
$ Xattr-c *. png
Deletes the extended attributes of all jpg files in the current directory.
$ Xattr-c *. jpg
We have deleted all of them now,
Now you can go to your hard disk to view these images. They can all be turned on and there is no gray state.
If you are not using jpg or png files, or video or audio files, use the same method.
