Tiger installed, with slight bruises

Finally got around to installing Mac OS 10.4 Tiger. I chose a so-called "clean install" option, i.e. erasing the internal hard drive of my Mac mini and installing a fresh version of the OS on it.

Of course I took precautionary measures. First of all I prepared a backup volume on my second external firewire drive, aptly called "backup". Used CarbonCopy to make a clone of my "old" Mac Mini system. To make certain that everything went according to plan, I even ran it through the Apple Hardware Test (Quick). Everything OK. Booted from the clone volume, OK. Had some coffee.

Now that I had a working fallback position I deftly installed Tiger on my mini, went quicker than I thought. Left out all the superfluous languages and printer drivers (just Epson and Canon for me). And, voilá, there I was with a fresh system.

The trouble began when I decided to use the Migration Assistant, a new helper app to be found in the Utilities folder. For one of the reasons I often balked at upgrading to a new OS was because of moving all my apps and personal settings over to the new OS. Sure, Apple has the "Archive and install" option, but I was forewarned not to use this (see this article and I just like to have a clean slate when I start using a new OS.

Since I was not migrating from another computer I chose as migration methodFrom another volume on this Mac. After selecting the correct working volume mymacmini and some encouraging purring from the harddrive - it just hung. The daisywheel kept turning and turning and I was not able to continue the process of migration. In fact I had to force quit the app. Tried out many different things, to no avail. Then it occurred to me that maybe the it had to do something with screwed-up permissions on the clone volume. So I booted into this volume, repaired permissions, returned to my Tiger volume, ran the Migration Assistant again and then after a brief second of suspense - it worked.

So do your homework before migrating and repair your permissions.
