I am still on XP with service pack 2. I had to change my browser to fire fox because IE no longer supported my OS. Now I am having issues with firefox not support my XP. I never updated anything beyond service pack 2.
My imac at home is a 2006 G5 running Tiger 10.4 I can no longer update it beyond 10.5 Leopard since it is a non intel processor.
I think my updating phobea is because "back in the day" any updates usually meant software incompatibility and midi issues and I learned it it aint broke dont fix it.
