Mac OS .bundle files not supporting 64-bit - Flagged as "Disallowed Architechture" by iTunesConnect


We are currently making a build for Mac OS, and trying to upload to iTunesConnect.
Unity integration is using Version: 1.09.03

When trying to upload to iTunesConnect we get the following error:

1 package(s) were not uploaded because they had problems:

ERROR ITMS-90240: “Unsupported Architectures. Your executable contained the following disallowed architectures: ‘[i386 (in com.FantasticYes.Returner1Mac.pkg/Payload/Returner, com.FantasticYes.Returner1Mac.pkg/Payload/Returner]’. New apps submitted to the Mac App Store must support 64-bit starting January 2018, and Mac app updates and existing apps must support 64-bit starting June 2018.”

This is probably also a problem for gvraudio.bundle as deleting the two other bundles produces the same error on gvraudio.
We have tried flagging the architecture import settings in all 3 combinations, (x86 + x86_64 and only enabling each), and have also done this for the editor platform, but with no luck.

Is there a way we can resolve this issue without having to update to a newer version of FMOD?


The fmodstudio bundles do support 64 bit, they are a universal lib that also contains the 32 bit lib as well. This may be the problem, as seen in this case:
