Use caution when upgrading to Snow Leopard

If you have an Intel Mac and might be thinking about upgrading to OS 10.6, use caution. While most people will probably have no issues with the upgrade, my first installation halted about halfway through, with the OS in a completely unusable state. The only thing that saved me was a Time Machine backup. If you are planning on upgrading, please back up your data first, just in case.

Also note that OS 10.5 (Leopard) was able to run software that was written for non-Intel Macs. 10.6 has that ability also, but you have to choose a custom install, and select that Rosetta be installed as well. This will enable some older software that might exist on your Mac to continue working.
