Installing TT 2025 on Mac with error code -36

System:

Apple M2 Pro

16GB 

Tahoe 26.5

I purchased the app online and downloaded the dmg directly from https://shop.app.intuit.com/unified/downloads?route=myaccounts&cgcview=downloads

I rebooted and downloaded the app multiple times with no success. 

TurboTax Desktop 2025 is still Intel‑only code. On Apple Silicon Macs, it runs via Rosetta 2 translation. Rosetta 2 is still available under macOS Tahoe 26, so Intel‑built TurboTax will work on M‑series Macs, though performance may vary slightly depending on your hardware.

this is what I found on the web. hope it helps. as a last resort contact TurboTax support

Step-by-step fixes

1. Verify prerequisites

• Ensure your Mac meets TurboTax 2025’s minimum system requirements 

• Confirm you have administrator rights: Apple menu → System Settings → Users & Groups → your account → “Allow user to administer this computer” must be checked. 

• Turn off file sharing (Apple menu → System Settings → General → Sharing → uncheck all) 

2. Remove corrupted installer files

• Empty the Trash.

• Quit TurboTax and remove any old versions from Applications and ~/Library/Application Support/TurboTax. 

• Delete any .DS_Store files in the TurboTax app bundle and its cache folders. 

3. Reinstall cleanly

• Close all apps, then restart your Mac.

• Open the .dmg file, drag the .app into Applications, and right‑click → Open if Apple Security blocks it. 

• If you get the “can’t be opened” block, choose Open again in the second prompt 

4. Fix Finder error -36 directly

If the installer still fails with -36:

• Locate the file in the installer that’s causing the error (Finder will name it with a leading . and trailing _).

• Right‑click → Get Info → ensure Read & Write is allowed for your user 

• If the file is corrupted, delete it and let the installer recreate it.

• For persistent issues, use a Mac optimization tool lto clear junk and fix Finder issues 

5. Network and security checks

• Use a wired broadband connection during install 

• Temporarily disable firewall/antivirus during install, then re‑enable afterward .
