    This seems like an unusual request, but is there a way to force an application to use more RAM. I just got a new macbook pro 13'' with 8 gigs of RAM, a lot compared to my old macbook with 2 gigs. I use Screenflow for recording and editing video and it is crazy slow and laggy. When I check activity monitor it is only using around 100-200 megabytes or RAM, while I have a few gigabytes free. Does anyone know how to fix this? Thanks!

    I have never heard of anything that lets you do this. Sorry.

    The amount of RAM used is something decided by the application developer. I never heard of an app that let you decide how much ram to use.

    Adobe Photoshop Elements allows you to select the amount of memory it can use, up to the limit available for a 32 bit app. Of course, that ability is internal to PSE. I don't think there are any apps that allow you to directly set the amount of memory used internally by another application.
