I have been running BOINC/CPDN on a Mac mini for a while without major problems. However, I have just purchased a new Intel Core Duo iMac and am finding it impossible to get a work unit processing.

I set up the new machine using the transfer facility from the Mac mini. This transfers applications as well as user files, so BOINC and CPDN were on the iMac when I started using it.

I assumed that it was working on the same work unit that was on the Mac mini (which I intend to continue using), so I disconnected the iMac from the CPDN project and then reconnected. This prompted it to download a new work unit, but it almost immediately crashed.

I wondered whether the problem might be that the required library had not transferred, so I deleted all of the BOINC folders I could find and re-installed from scratch, starting with the required library.

Installation appeared to be fine and I was able to connect to CPDN and download a work unit. However, this too crashed almost immediately after starting computations.

I left it overnight and it transferred another work unit first thing this morning and that too started calculating and then almost immediately crashed, showing a computation error.

Is there a problem with running BOINC/CPDN on the Intel Macs or has the transfer created a problem?

Any help getting up and running would be greatly appreciated.

Regards, Brian

I think the problem may be because no software has been created yet for the new Intel Macs.

Les - thanks for the reply.

I thought the Rosetta software was meant to enable \"old\" PowerPC applications to run on the Intel machines - is there a reason why would it not work for BOINC/CPDN?

This is where my ignorance shows itself, but is it the BOINC software or the CPDN model that will need to be updated to cope with the MacIntel platform? Whichever it is, do you have any idea when updated software might be available?

I tried detaching from the Climate Prediction poject and connecting to other projects. I have now succssfully processed several work units for predictor@home and am currently running a work unit for Einstein@home.

So it does look as though the problem really is an incompatability between the climateprediction.net model (or at least the sulphur variant) and the Intel Mac machines.

Hopefully this will be addressed at some point as I would like to get this machine working on the climateprediction.net project asap. Can anyone advise whether this is a known issue and whether / when a solution is planned?

Thanks, Brian

The science app will need to have a version for Intel Macs, and possibly BOINC will as well. I\'ve no idea what Rosetta is doing/has done.
There\'s no timetable yet for software release. Just sometime this year.

Thanks for the clarification Les - no criticism intended. I will endeavour to be patient while waiting for the Mactel version of CPDN to arrive. Regards, Brian
