I run one model under WinXP and Grid Republic Desktop (recently migrated from a WinXP PC to a Parallels WinXP virtual machine) and another model by the Tiger native BOINC app. I would rather run both models natively on the Mac, because (among other reasons) I don\'t run Parallels continuously.

To migrate the first model from the VM to the Mac, I tried copying the [modelname] directory from C:\\Program Files\\BOINC\\projects\\climateprediction.net\\ to /Library/Application Support/BOINC Data/projects/www.climateprediction.net/ --that is, I placed it side by side with the directory holding the model that was already running by the native Mac OS BOINC app.

My native Mac OS copy of the BOINC app did not recognize the model I copied. What am I not doing right?

You MUST copy ALL of the folders and files, starting with BOINC.
There are bits of information all through them that relate to each work unit, which project it\'s for, and where it\'s up to in the processing.

So, if you\'re already crunching something, you\'ll have to set the projects to No new tasks, in the projects tab, and then wait until all work units have been completed and uploaded.
THEN you can copy over the WUs from the OS, by replacing the current BOINC with the other BOINC.

PS
I\'m not a Mac person, so the only Tigers that I know about are the big cats, Panthera tigris.
If your Mac isn\'t an Intel type, then the climate models won\'t work anyway.

There are md5 checksums for the binaries and the WU files. If you change the binary from a not finished model, it would change the md5 sum and reset the model.
I think, the best solution is to finish your current modell it with Parallels, VmWare or CrossOver - or let them finish on your Windows system and download a new model on your Mac.
I have made a good expirance with running a CPDN model at crossover on MacOS Intel. CrossOver had the less overhead in crunchingtimes compared with Parallels. - But, I have tested it with a older Parallels Beta.
