Wrapper Damaged on Mac OS X 10.9 Mavericks?

Short answer - they are not. - Here is how to fix it.
With Mac OS X 10.9 Mavericks, users have been complianing of errors after downloading a wrapper (or files).

The error states. that the .app or .dmg etc is damaged and you should drag it to the trash.

Basically, this a security feature* of Mac OS X 10.8+ (in later builds of Lion as well) - called Gatekeeper.

To Fix this issue:

-> If you turn "off" gatekeeper, the error will not occur. -> Open System Preferences > Security & Privacy > General, and choose “Anywhere" under “Allow applications downloaded from”.

-> Alternatively, (not sure if this works anymore) - another way of bypassing Gatekeeper is to open an .app while holding down the Control key and choosing Open

-> Last, you can run a terminal command. Open up Terminal and run:

sudo xattr -r -d com.apple.quarantine /path/to/Eclipse.app
- > Replace "Eclipse" with the name of the app you are trying to Open.

*Feature - actually means that Gatekeeper is the first step in Apple's plan to kill off all non-Mac App Store apps....


Holding control and choosing Open still works.

And you should get a notice that it can't open because it's from an unidentified developer, not because it's damaged.

If it says it's damaged, I'm inclined to believe it has been tampered with in an unusual way (thus actually damaged). See the apple support link you posted.
Zorg, people are complaining that it is damaged, and it is not. There are some posts in threads, in the port database claiming "damaged" when it is not.

I agree, that it this also holds true, for the "unidentifed developer" "error" too.
The damaged and unidentified error messages should logically trigger for different reasons. Well, at least on the latest OS to be safe.

Executing spctl --assess --type execute <binary> should either output nothing (it's code signed properly), rejected (not signed), or something else (damaged). Damaged could imply developers alter something after signing or users do (say, using some app-stripping utility, or their unzipping tool failed). Note that it is still possible to self-sign a binary and be an unidentified developer.

Downloading and opening Eclipse gave me an unidentified warning, though.

Yeah it is the unidentified developer error, You have to turn it off in the Security and Privacy settings: Allow apps downloaded from (anywhere).
i turned off the security settings and now the wineskin can't open on my mac
I have the same problem as bill.cosby. I turned off the security setting and the wineskin just won't open. It gives me a message stating that the file might be incomplete or damaged.
Hey guys,

I know im shooting off with a tangent...

I downloaded the game F.E.A.R (the first part) and it said that it requires CXZ Black Diamond, which I downloaded and installed but the game still doesnt come on!

Ive also downloaded wineskin winery and Xquartz...

Could somebody help on how to get this game to work on mac os x mavericks or is it just a dead end?
If you wanna bypass the problem with Unidentified Developer you can make a new folder and call it what you want.
Then right click the app and show contents. Copy all contents to your newly created folder, and add the extension .app to the folder name.
This basically makes you the developer of the app. Happy gaming folks
Strangely, just downloading in Chrome instead of Safari fixed this for me.
