That’s very strange. That’s seems like a 32bit app error but that shouldn’t be happening as the game is 64 bit now and other macOS gamers aren’t having this issue. There might be something else wrong here. Are you sure you’re using the new launcher? Do you have the launcher and the eso app added to the macOS system preferences security, accessibility? I suggest contacting ESO support through the support ticket system because it seems like these “Customer Support” Mac forums are being ignored by the ZOS Support team. Also, when you get the first ticket response by email, it’s generally some copy/paste knowledge base article that’s not even related to, or doesn’t solve the issue, then you have to respond to that for an actual person to see your query and hopefully assist you in resolving it. Keep in mind that the support team is also probably overwhelmed with the amount of tickets right now due to more people playing while in lockdown so you’ll probably have to wait a week or two for an actual human to get back to you.
