My apologies for the trouble.
As per our engineer, for backwards-compatibility with older versions, we’re still 32-bit. But rest assured that we plan to eventually migrate to 64-bit, while dropping support for some very old versions of MacOS.
If you guys encounter any further issues, please send us an email at firstname.lastname@example.org with the link to this post. Kindly include all relevant details such as those found here. Thank you!
