Mac如何消除系统更新小红点?

忽略大版本提示:

sudo softwareupdate --ignore "macOS Catalina"
sudo softwareupdate --ignore "macOS Big Sur"

忽略小版本提示:

sudo softwareupdate --ignore "macOS Catalina 10.15.4 Update"

取消小红点:

defaults write com.apple.systempreferences AttentionPrefBundleIDs 0
killall Dock

恢复更新提示:

sudo softwareupdate --reset-ignored
defaults write com.apple.systempreferences AttentionPrefBundleIDs 0
