Frequently Asked Questions (FAQ)
The YucDu macOS app is still in development and is not yet available on the Mac App Store. This guide is based on the current development build; features and screens may change before release.
Can I download the macOS version yet?
Not yet. The macOS version is still in development and is not yet available on the Mac App Store. The macOS version is the same app as the iPhone and iPad versions.
Which version of macOS do I need?
macOS 15 or later.
Do I need to sign up or sign in?
No. Open the app and read every article; favorites, search and offline reading don't need an account either.
Why doesn't a second copy open when I launch the app again?
Only one copy of YucDu runs at a time. Opening the app while it's already running brings the existing window to the front. To read several articles at once, press ⌘N to open a new main window, or right-click an article and choose "Open in New Window". See Windows and Layout.
Why is the app still running after I close the window?
Following macOS conventions, closing the last window doesn't quit the app. Click the Dock icon or press ⌘N to open a window again; press ⌘Q to quit completely.
My favorites aren't syncing to my iPhone or iPad
Please check that:
- This Mac and your iPhone/iPad are signed in to iCloud with the same Apple Account.
- Settings > Data > "iCloud Sync" shows "Syncing". If it shows "Not signed in" or "This device only", your favorites are currently saved on this Mac only.
See Library for details.
Do reading history and progress sync to my other devices?
Not at the moment. Only favorites sync through iCloud; reading history, reading progress and search history are kept on this Mac only.
My offline articles have disappeared
Possible reasons:
- Offline articles expire 14 days after they're saved.
- "Clear All" was clicked in "Offline Reading".
- The article has been unpublished on the website, so the app no longer shows its full text.
Search shows no results or doesn't work
Search needs an internet connection and isn't available offline. If you're online but nothing is found, try different or shorter keywords.
How do I refresh the content?
The macOS version currently has no menu command or shortcut for a manual refresh. The app automatically fetches newer content from the website as pages are shown, so you normally don't need to do anything.
Why haven't I received any new-article notifications?
New-article notifications are being prepared and are not being sent yet. See Notifications.
Why are there no ad options in Settings?
Because the macOS version has no ads.
How do I change the interface language?
The interface language follows your macOS language settings. To choose a language just for YucDu, go to Settings > "Language" and click "Open" to adjust it in macOS System Settings > Language & Region. Supported languages are 日本語, 繁體中文, 简体中文, English and Tiếng Việt; if your system language isn't one of them, the app is shown in Japanese.
What keyboard shortcuts are there?
Common ones include ⌘F to search, ⌘D to favorite, ⌥⌘↓ / ⌥⌘↑ to move between headings, ⌘[ to go back, ⌘1 / ⌘2 / ⌘3 to switch to Home, Explore and Favorites, and ⌘+ / ⌘− / ⌘0 to change the font size. See Menus and Keyboard Shortcuts for the full list.
