My long suffering non tech wife has the dubious delight of upgrading the iMac G3 600Mhz at home from Jaguar to Panther so we can iChat. I will be providing telephone support from here but I wanted to know from those who have done it before what is it like? Is it very easy? Anything I should know before she says "is it supposed to do that!"? When I did OS9 to Jaguar it was very simple.
