Hello,

I need to share a macmini/notebook for multiple vesrions of Mac (10.3,10.4,10.5). Right now I format the disk and then reinstall the reuired Mac version. But it is very tedious job. Would somebody suggest some good method to do this?

I found that once you have upgraded the Mac, you can't downgrade it. To do it, you need to format and reinstall.

Any suggestion(ASAP) would be most welcome.

something like VM Fusion or Parallels?? I use them to run windows in my Mac. I've read that you could run Linux, etc on them too. Google them and do some research. It might solve your problem.

Cheap external drive, with the two other versions of the OS that you need to run.

Just partition an external into 2 partitions (or more) and format and install the require OS on each partition.

You should be able to hold the modifier key at restart, or simply just go to System Preferences > Startup Disk > and choose the version you need.
