@bnastic I’m guessing related to the system disk cache, since other heavy I/O also triggers problem. Not sure why it won’t use the free RAM.
@bnastic Retina MacBook Pro, so I think “no.â€
@bnastic So something is getting cleared or reset when I reboot, but I’m not sure what.
@bnastic I tried purge, and it increased the free RAM by 1 GB but didn’t help Aperture, which wasn’t only using about 2 GB.
I don’t understand why restarting the Mac speeds up Aperture so much when I have 4 GB of free RAM.
