Hi,
It has stopped the problem, thanks - with the added bonus that my macbook air seems to be running faster too! However, I am still not convinced that there is not some sort of malware, because in the ASL messages there are some comments that appear very strange to me ; eg, 'you're not that important. Ignoring. The timeout key is no longer respected.It never did anything anyway. The Hopefullyexists last key no longer exists.Ignore it.Please switch away from OnDemand to KeepAlive. The HideUntilCheckin property is an architectural performance issue. Please transition away from it.Bug in libdispatch client....'etc etc Is this normal stuff to find in a Mac log??
