A few questions.Straight answers.
Is Sum part of Yuzu Drag?
No. Yuzu Sum is a standalone Mac app. It has its own window, shortcut and updates.
Which exchange rate does it use?
VND pairs supported by Vietcombank use the bank’s transfer rate by default. You can choose buy or sell. Other pairs use ExchangeRate-API mid-market rates through USD. Converted results show the source and time.
Can I use it offline?
Yes. Sheets and calculations work on your Mac. Currency conversions use the last saved rate, or the bundled snapshot before the first update. Check the rate’s timestamp before using it.
Which Macs can run the beta?
Yuzu Sum requires macOS 14 or later. It runs on Apple silicon and Intel Macs. The download is a signed, notarized DMG with app updates through Sparkle.
Your next sum.One shortcut away.
Download the standalone Yuzu Sum beta for Mac. Open the DMG and move Yuzu Sum to Applications.
