Hi, i have a mbp as discribed in my sig. Lately, whenever im working with 6-8 apps open my apps start crashing 1 by 1 an soon enough my mac needs to by rebooted by means of the power button. Then after a reboot my mac starts to reindex and the probleem reoccurs after 20 min. I noticed that my processor starts processing heavy before the crashes via istat pro 3. I already tried restoring disk permissions, are there any other standart or non-standart steps i can try? Thanks in advance, i really need a working mac for school.
