本站 2 月 25 日消息，科技媒体 MacRumors 昨日（2 月 24 日）发布博文，报道称由于导致存在“循环重启 / 变砖” BUG，苹果公司已暂停向部分 iPhone 和 iPad 机型验证 iOS 18.4 Beta 1 更新。
本站援引博文报道，iOS 18.4 首个测试版不再适用于 iPhone 12 mini、iPhone 12、iPhone 12 Pro 和 iPhone 12 Pro Max 等机型，以及部分旧款 iPad Air 和入门级 iPad。
根据用户反馈，上述机型安装 iOS / iPadOS 18.4 Beta 1 更新后，出现“启动循环”，致使设备无法使用。除启动循环问题外，部分蜂窝版 iPad Air 机型可能还存在其他问题。
苹果公司还暂停向 Apple Watch Series 6 推送 watchOS 11.4 首个测试版更新。
苹果公司后续将重新为受影响的设备提供 iOS / iPadOS 18.4 和 watchOS 11.4 测试版，但具体时间尚不清楚。
