yes, you won't loose any work.

Same issue with the update so will have my mac crunch a different project.

It started lately but moved on to a different project. I have 8 real cores crunching one one project at a time. Am on HCMD2 now. Was getting long run times there too but would adjust its time within a few hours. I will be back crunching HCC after I get sapphire in the other project.

Shut down my mac while on vacation for 5 days. Came back and started on this project again. After downloading the wu's, it showed a little over 2 hrs to crunch. Got off work to see how it was going. My 2 hr wu's turned into 12 hr wu's. Am on 6.2.18. The message area does not reveal any problems. Will the boinc logs (can't remember the names) show any info about possible processor reduction? Might pull the plug on the mac until snow leopard 6.3 gets released and try again. Am using leopard 5.8 right now. Been looking for a program that monitors the processor and logs any change but not finding anything yet.

Find a tool that can monitor page file errors and kernel time under OS-X. Those are the source of performance losses that were omnipresent on all platforms early in HCC, then largely removed, dramatically improving performance, at least under Windows. They're flying under W7-64 bit, mostly in the quorums I see faster, sometimes full 2 to 3 times to the wingman.
