Re: Acrobat excessive RAM usage Reply #105 – March 01, 2018, 03:28:04 PM Quote from: sgrhill on November 21, 2017, 05:25:28 AMQuote from: Joe on October 04, 2017, 02:29:56 PMWhat version of Mac OS are you using? I am not seeing this with Acrobat DC on Mac OS Sierra 10.12.6.The problem occurs in Yosemite, Sierra and High Sierra.And El Capitan too.Was fine until about 1 1/2 weeks ago, then DC started grabbing up ram & VM. No updates to OS, Acro or the only third party plugin, FusionPro. There's also a second thread on Adobe's bug report pages. https://acrobat.uservoice.com/forums/590923-acrobat-for-windows-and-mac/suggestions/32123662-acrobat-pro-dc-acrocef-eating-up-21gb-of-memoryOnly workable solution I've found, as others on this forum, quit Agrobat when not using it and don't leave it launched for over 1/2 hour (monitoring memory use through Activity Monitor).
