Mac系统太旧,根证书过期导致。

(参考:https://docs.buddybuild.com/troubleshooting/install_updated_wwdr_cert.html

解决方案1:

升级Mac系统到新版本(10.14以上)

解决方案2:

手工安装WWDR根证书

1.前往 https://www.apple.com/certificateauthority/ 并下载安装"WWDR Certificate (Expiring 02/07/23)"证书

2.打开「钥匙串」,菜单栏 => 视图 => 显示过期证书 (Menu => View => Show Expired Certificates)


3.寻找过期的「Apple Worldwide Developer Relations Certification Authority」并删除(红色字体)
