# Greypaint Greypaintは、Sparkle appcast、Homebrew、GitHub Releases、Mac App Storeを一つのリストで確認できるmacOSアプリ更新ツールです。利用可能な更新を確認し、適用時期を管理し、選択したアプリを一元管理できます。 - Findings24: - ウェブサイト: - 料金: Freemium - カテゴリー: Productivity Tools ## Greypaintとは？ Greypaint is a macOS utility that checks multiple update channels used by Mac software, including Sparkle appcasts, Homebrew, GitHub releases, and the Mac App Store. It consolidates available updates into one list so users can review apps from different distribution sources in one place. The app emphasizes user-controlled updating: it can check on a schedule or manually, flag major and incompatible releases, explain what will happen before an update, and let users choose which updates to apply. It also includes coverage for Homebrew formulae and npm packages, while keeping command-line tools from being updated without the user’s instruction. ## Greypaintでできること ### Multi-source update checking Checks Sparkle appcasts, Homebrew casks, GitHub releases, and Mac App Store data and presents the results in one list. ### Scheduled or manual checks Can check with the window closed on an hourly, six-hour, daily, or never-unless-requested schedule. ### Review before installing Shows what changed, what could break, and what the update will not do before touching an app. ### Release and compatibility controls Flags major-version jumps, lets users skip a version, and explains when an update requires a newer Mac or macOS. ### Rollback and app-status details Provides a rollback path to a previous version and calls out apps still using Rosetta or apps whose developers have discontinued them. ### Keyboard and package-tool support Offers configurable shortcuts and also checks Homebrew formulae and npm packages without updating command-line tools automatically. ## 利用シーン ### Maintaining apps from different sources Use one review list when a Mac contains a mixture of indie apps using Sparkle, Homebrew-installed software, GitHub-distributed releases, and Mac App Store apps. ### Controlling update timing Choose scheduled checks for routine visibility, or use manual checking when updates should only be reviewed on demand. ### Evaluating major or incompatible releases Review major-version flags, skipped releases, and macOS requirements before deciding whether an update is appropriate for the current Mac. ### Troubleshooting an update Use refresh controls, the App Store button, update logs, and permission guidance when a result is stale or macOS prevents an app replacement. ### Managing developer tools cautiously Monitor Homebrew formulae and npm packages from the same utility while retaining control over when command-line tools are changed. ## よくある質問 ### Which update sources does Greypaint check? It checks Sparkle appcasts, Homebrew casks and formulae, GitHub releases, and Mac App Store data. It also includes npm packages among the command-line tools it can check. ### Can Greypaint install updates automatically? The product describes user-controlled behavior: major versions never install on their own, command-line tools are never updated without the user, and other updates can wait for user action. It also states that security fixes can install quietly, so users should review the app’s settings and update prompts for the behavior that applies to each update. ### How often can Greypaint check for updates? The available schedules are hourly, every six hours, daily, or never unless you ask. Manual checking is also available. ### What happens if an update needs a newer Mac or macOS? Greypaint identifies the missing update and explains when a release requires a newer Mac or macOS. It can also flag major-version changes and let you skip a version. ### Does Greypaint offer a trial and refund policy? The site offers a 14-day trial with every feature included. It lists a $6.49 lifetime license with updates included and no subscription, and says a refund can be requested within 14 calendar days of purchasing the lifetime license, subject to the published policy. ## クイック情報 - **Category**: Mac app updater - **Platform**: macOS 26.2 or later - **Update sources**: Sparkle, Homebrew, GitHub, and Mac App Store - **Command-line packages**: Homebrew formulae and npm packages - **Trial**: 14 days with all features - **License**: $6.49 lifetime license; updates included; no subscription
