When launching Acrobat on a Mac, you receive an error message that includes the words, "The serial number 1591[...] is already in use by the maximum allowed computers."

  1. Close all Creative Cloud and Adobe services using Activity Monitor.
  2. Download and unzip this file.
  3. In Finder, go to Go > Go to Folder... > Type in "~/Library/" > Preferences and insert the downloaded and unzipped file (com.adobe.acrobat.pro.DC.plist). Authenticate if necessary. If a file with the same name is already there, replace it with the downloaded file.
  4. Open Terminal, and run this command: sudo killall cfprefsd
  5. Restart the machine.
