Contact Adobe Customer Care for an OS Swap

Since serial numbers are OS-specific, you must contact official support to exchange your Windows license for a Mac license.

Adobe Acrobat perpetual licenses and certain serial numbers are platform-specific. A Windows serial number cannot activate a Mac installation. If purchased recently, Adobe support can usually review your order and swap it for the correct operating system version.

1
Log in to Adobe

Go to the official Adobe website and sign in with the Adobe ID associated with your recent purchase.

2
Access the Help Center

Navigate to the Adobe Help Center and select 'Contact Us' or look for the chat icon in the bottom corner of the screen.

3
Request an OS Version Exchange

Click the 'Still need help?' button to chat with a live agent. Explain that you purchased the Windows version by mistake instead of the Mac version.

4
Provide Order Details

Give the agent your order number and the incorrect serial number so they can verify the purchase and issue a replacement Mac serial number.
