I know this is a duplicate, but the previous did not help much.

Trying to use this tool to decrypt a Youtube IPA (not thinned, downloaded using ipatool). Giving foulplay two IPA duplicates does not work, but giving it two identical YouTube "exec" (inside of the payload package of the IPA) seems to at least start foulplay.

Fouplay fails with the error "mremap_encrypted: Cannot allocate memory"

I'm not sure if I'm using it wrong or if I have some incorrect setting. Any help would be appreciated.

I found this project on Reddit and was hoping it could be used to side load iOS apps onto my M1 Macbook Air. I cloned the foulplay project and compiled it but all I have now is a Unix Executable File that doesn't seem to do anything when double clicked or ran through terminal. Not sure what to do from here.

Happens immediately after running the script

I am getting mremap_encrypted: Operation not permitted log
and mremap_encrypted: unable to create decrypter com.apple.unfree +
AppleFairplayTextCrypterSession::fairplayOpen() failed messages inside device console.

I'd tried to disable SIP and AMFID, but no any result.

I am launching program like this sudo ./decrypt binary binarydupe with All File Disk and Privacy privellegies.

mremap_encrypted fails with "Cannot allocate memory" when testing on M1 mac

Target binary is a universal app, thinned to arm64 with lipo.
