mremap_encrypted: Cannot allocate memory

[michaeleisel]

When trying to decrypt the latest eBay.app/eBay executable from the app store, I get the following:

$ ./unfairplay Payload/eBay.app/eBay eBay-decrypted
mremap_encrypted: Cannot allocate memory
Please wait 1 second and try it again.
Succeeded in decrypting the binary.

Even after retrying several times, it still fails. Any ideas? Note that I'm trying to decrypt this iOS app from my arm mac.

You need to downgrade your mac to macOS 11.2.3 or below.

You need to downgrade your mac to macOS 11.2.3 or below.

What's the reason for macOS 11.2.3 requirement? Changes in the underlying mremap_encrypted implementation?

[subdiox]

Yes, that's right.

Just for a reminder, make sure you have logged in with the Apple ID you used to download the app. If you are not sure, install the ipa to your system and double click on it to make sure it launches.
