⚠️ Fix for "App is damaged" error

Since Wansan is not notarized by Apple yet, macOS may falsely flag it as "Damaged".

Step 1: Drag the app to your Applications folder.
Step 2: Run this command in Terminal to remove the quarantine flag:
sudo xattr -r -d com.apple.quarantine /Applications/Wansan\ Studio.app Copy & Paste

*You will be asked to enter your Mac login password (typing will be invisible).

WANSAN

The Origin of the Name

Named after Shen Wansan, a legendary merchant and mathematician from the 14th century,
renowned for his ability to accumulate and manage immense wealth.

Just as Wansan was the master of commerce in his time,
we built Wansan Studio to help you master your data—privately, locally, and profitably.

Edward

Meet the Maker

Hi, I'm Edward.

I built Wansan Studio because I was fed up with over-engineered BI tools.

Product managers always make dashboards unnecessarily complex. But in reality, we just need simple answers to simple questions.
So I built the tool I wanted: Drag, Chat, Report. Done. No bloat, just speed.
