Does update (15th May 2018) fix Memory Leak - batch processing just fills up all RAM until computer crashes. Partially solved by installing an earlier Adobe RAW version. Im using a MacPro 3,1 with 32gig ramSSD and Raid 0.
Alan, can you tell me what type of files you're using with ACR and how many you batch process? Can you also provide some more information as to what the batch process is doing? Or better yet, share an action that recreates your batch process so we can run and test it here.
