# IDA Pro 9.1 macOS Installation & Fix Guide
This guide helps you resolve the error: **“IDA Professional 9.1 is damaged and can’t be opened. You should move it to the Bin.”**
This error typically occurs on macOS when downloading software from unofficial sources or when the app's code signature is invalid. It is often caused by macOS Gatekeeper security features.

## 1. Remove Quarantine Attribute
macOS may set a quarantine flag (`com.apple.quarantine`) on downloaded apps, blocking them from running. To remove it:
1. Open **Terminal**
2. Run the following commands:
```bash
xattr -l "/Applications/IDA Professional 9.1.app"
sudo xattr -rd com.apple.quarantine "/Applications/IDA Professional 9.1.app"
xattr -l "/Applications/IDA Professional 9.1.app"
```
3. Try opening IDA Pro 9.1 again from the Applications folder, Spotlight, or Launchpad.

## 2. Allow App in Security & Privacy
If the app is still blocked:
1. Go to **System Settings** → **Privacy & Security**
2. Look for a message about IDA Pro being blocked
3. Click **"Allow Anyway"** next to IDA Professional 9.1

## 3. Open via Right-Click
1. Right-click on IDA Pro in Applications
2. Select **"Open"**
3. Click **"Open"** when prompted
---
## 4. Open via Terminal
If GUI methods fail, try:
```bash
open "/Applications/IDA Professional 9.1.app"
```

## Why This Happens
- Downloaded from the internet (e.g., via Brave browser)
- macOS automatically quarantines the app
- The quarantine flag prevents execution
---
## Result
If you follow these steps, IDA Pro 9.1 should open normally.
