Apple today released a new version of the HomePod 15 beta software, following reports from users that the original HomePod 15 beta was causing heat issues and sudden failures that were rendering their HomePod inoperable.
The new beta version of the HomePod 15 software also appears to introduce Lossless Audio support for the HomePod and the HomePod mini.
HomPod beta software is distributed on an invite-only basis, so no update is available for download by developers or the general public. While there are ways to get the HomePod software if you’re not a part of the select testing group, it is not recommended that you install it in this way.
As noted by MacRumors, the release notes for the HomePod 15 update do not offer any information about whether the failure issue has been addressed.
