标题中的“不支持的Mac上的夜班:在较旧的不支持的Mac上启用夜班”指的是Apple的MacOS操作系统中的一个特性——夜班模式(Night Shift),它旨在通过调整屏幕色温来减少蓝光对眼睛的影响,帮助用户在夜间更好地入睡。然而,这个功能并不是所有Mac型号都支持,特别是那些运行较旧版本系统的设备。 描述虽然简洁,但暗示了存在一种方法或技巧,可以在官方不支持的Mac上启用夜班模式。这通常涉及利用终端命令或者第三方工具,绕过系统限制。 标签中包含了一系列与MacOS相关的关键词,如"macos shell bash",这表明可能需要通过命令行界面,使用Bash脚本来实现。"mac preferences"意味着可能涉及到修改系统偏好设置。"apple hackers"可能指的是技术爱好者或开发者,他们寻找非官方的解决方案。"macos-sierra sierra"、"highsierra mojave"是MacOS的不同版本,表明这个问题跨越了多个操作系统迭代。"nightshift night-shift"是夜班模式的关键词,而"Pike"可能是指某个开发人员或工具。 在"Night-Shift-on-Unsupported-Macs-master"这个压缩包文件名中,"master"通常与Git仓库主分支相关,可能指示这是一个开源项目,提供了在不支持的Mac上启用夜班模式的完整解决方案。 为了在不支持夜班模式的老版Mac上启用它,用户可能需要执行以下步骤: 1. **开启Terminal**:打开Mac的“终端”应用程序,这是系统自带的一个命令行工具。 2. **运行Bash脚本**:找到并下载那个名为“Night-Shift-on-Unsupported-Macs-master”的压缩包,解压后,里面应该包含一个或多个Bash脚本。这些脚本可能包含了用于模拟夜班模式的自定义命令。 3. **赋予执行权限**:在终端中导航到脚本所在目录,并使用`chmod +x scriptname.sh`命令给予脚本执行权限。 4. **运行脚本**:使用`./scriptname.sh`命令运行脚本,根据脚本设计,它可能会自动调整屏幕色温和亮度,模拟夜班模式的效果。 5. **定时任务**:为了使夜班模式在特定时间自动启用和禁用,可以使用`launchd`或`cron`设置定时任务。`launchd`是MacOS的后台任务管理系统,而`cron`则是一个Unix/Linux的时间调度程序。 6. **注意事项**:这种方法可能不是官方支持的,有可能会导致系统不稳定或影响其他功能。使用前应备份重要数据,并了解可能的风险。 以上步骤是基于对给定信息的推断,具体操作还需要参考实际提供的脚本内容。对于不熟悉命令行操作的用户,建议寻求专业帮助或寻找更用户友好的第三方应用来实现类似功能。
