使用OpenCore-Patcher可以在老的Mac电脑上安装新操作系统。但是有点电脑太老了,安装最新的跑不动,可以安装次新的操作系统。这样老是会检测到新版本并小红点提示,很麻烦,可以禁用更新。
在系统设置-软件更新-自动更新,点右侧小图标,关闭相关更新即可。
关于小红点,可以使用以下代码禁止显示:
# 软件更新不扫描网上信息
softwareupdate -l --no-scan
# 清除系统设置角标
defaults write com.apple.systempreferences AttentionPrefBundleIDs 0
# 重启程序坞
killall Dock
# 其他人说的下面的方法,在新版本的MacOS已经不适用
# softwareupdate --ignore "macOS Catalina"
