收到了邮件，大概的意思就是UA用户先不要更新 macOS 11 Big Sur，软件暂时不兼容，等以后 UA 发布更新支持 macOS 11 后再更新。
As you may know, Apple is releasing macOS 11 Big Sur on Thursday, November 12th.
Please note that UA software, including UAD, Apollo, and LUNA, is not currently compatible with macOS Big Sur.
To prevent macOS from updating automatically (and to keep your UAD/Apollo system rocking):
Please be sure to uncheck “Install macOS updates” in System Preferences > Software Update > Advanced options.
UA software compatibility with Big Sur is being thoroughly tested, and full qualification is coming in future software updates.
For more information and the latest macOS Big Sur news, please read the article posted in our Knowledge Base:

Thanks and stay tuned!
Sincerely,
The UA Support Team
