I am a long time Mac and Logos user and have managed this problem for a while now, but the iMac that the church has provided is struggling and I am hoping someone can help. This mac has 8gigs of ram, which should be plenty, but, Logos seems to absolutely kill the ram on this. My Mac at home had a similar issue but since I upgraded the ram I no longer notice the drain. I can literally watch my available Ram go down moment after moment. And even with nothing running on this iMac, the absolute most ram it shows available is around 4 gigs. With a word doc, an internet browser and Logos going it can be really slow.
So, are there tricks, tips, or settings that I can adjust in Logos that limits the ram usage on the mac? Unfortunately, this iMac is not easily upgradable, and I would be very hesitant to try it myself.
