find . | xargs -0 xattr -c

This will clear attributes for all files.

In Sierra, the rules on what can be in a signed bundle have been tightened, and resource forks are no longer allowed. AppleScript has been saving information in resource forks forever, although that information has been unused for a long time. With Sierra, when you save a script, this resource fork information will no longer be saved.

It means you cannot codesign a script that was last saved in a version before Sierra; you have to save in Sierra to be able to sign in Sierra.

The people likely to be affected by are who bundle other scripts within their scripts (cordova?). They will not be able to sign the container script until all the embedded scripts have been resaved under Sierra.

UPDATE:

Seems like this also works:

xattr -rc .

If you have any insufficient permissions error try to prepend sudo: sudo xattr -rc .

先在终端输入然后重启xcdoe

xattr -rc .

如果不行终端输入 ，然后重启电脑 ok

sudo xattr -rc .
