How to Fix Acrobat Color Format Not Supported Scanning Error on Mac
Question details
The user encounters a 'Selected Color Format Is Not Supported' error when attempting to scan a color document directly into Adobe Acrobat on macOS.
- Product
- Adobe Acrobat
- Device & OS
- macOS
- Scenario
- Trying to scan a document in color directly into Acrobat using an external multifunction scanner.
- Observed behavior
- Acrobat displays a format not supported error and fails to complete the color scan, even though black-and-white scanning works and the manufacturer's native scanning software functions normally.
Ensure your scanner is securely connected to your Mac and powered on. Verify if the scanner can successfully scan in black-and-white within Acrobat, as this confirms whether the issue is strictly related to color formatting compatibility.
Update macOS, Acrobat, and Scanner Drivers
Outdated scanner drivers or Acrobat versions often cause color formatting conflicts with macOS.
Scanner-driver compatibility is the most common cause of the 'Selected Color Format Is Not Supported' error. Ensuring all software layers are updated can restore normal communication between Acrobat and your scanner.
Open the Apple Menu, go to 'System Preferences' (or 'System Settings'), and click 'Software Update' to ensure your Mac is running the latest OS version and driver packages.
Launch Adobe Acrobat, click on the 'Help' menu at the top of the screen, and select 'Check for Updates'. Install any pending updates and restart the application.
Visit the official support website for your scanner's manufacturer (e.g., HP, Epson, or Brother). Download and install the latest macOS-compatible scanner drivers or TWAIN/ICA utilities for your specific printer model.
Use the Manufacturer's Scanning Utility as a Workaround
If Acrobat continues to block color scanning, use your scanner's native software to create the PDF, then optimize it in your PDF editor.
A Seamless, Lightweight PDF Alternative to Acrobat

Frequently Asked Questions
Why does my scanner work in black-and-white but not in color with Acrobat?
Black-and-white scanning uses a simpler data protocol that is universally supported by the operating system. Color scanning requires specific driver instructions for color depth and formatting. If the scanner's driver is outdated or incompatible with Acrobat's macOS integration, it will trigger a format error.
Does this scanning error only affect HP and Epson scanners on Mac?
While frequently reported with HP and Epson multifunction printers on macOS versions like High Sierra and Catalina, this error can occur with any scanner brand. It happens when the macOS TWAIN or ICA drivers fail to communicate properly with Acrobat's built-in scanning interface.
Can I use Apple's Image Capture instead of the manufacturer's software?
Yes, Apple's built-in Image Capture is an excellent and reliable alternative. It interfaces directly with macOS core scanning frameworks, often bypassing the third-party driver bugs that affect Acrobat. You can use it to scan in color and save the file as a PDF, which you can later open in any PDF software.
