It just works. That used to be the reality for me when I used my iMac and have had an iMac (2 different ones for years). Now the QC of their OS is absolutely horrible. From bugs like not being able to scroll in Calendar (have to reboot to get it to work again) to the computer constantly asking for the yahoo password (for mail) even though it is correct, supposed to be autosaved, and has not changed. Even itunes is so dated and flawed to manage media on the ipad. I used to love photos and/or iphoto but now it is such a disaster and is constantly lagging. I will need to upgrade soon but am not sure if I should move away from Apple. My fear is that with a new OS coming out more and more bugs can be expected. Funny they release a new OS without fixing the old one.
