Same. MacbookPro, latest OS, latest Acrobat DC update, crashes after 15 seconds... been like that for months.
Trying restarting, reinstalling, erasing preferences, used the stupid cleaner tool, removed AcrobatDC entirely, same issue. Works for 15 seconds then hangs permanently with a spinning beachball. Unresponsive, have to force-quit.
I use Acrobat every day for my publishing job, and no fix evident. I administer all Adobe products for my organisation. Come on Adobe, let's have some customer service.
