Another classic Mac OS feature that was added into Jaguar was the Simple Finder - a very stripped-down Finder with access to only what the administrator gives that user access to, no Finder window toolbars, and no access to hard disks or partitions. This was one of the features from the classic Mac OS that was sorely missed - when dragging something from one location to another, it was possible to hold the item over a folder, wait a few seconds, and the folder would open up, so users didn't have to find the destination location in advance.

The spring loaded folders feature was added into Mac OS X with Jaguar. Mac OS 10.2 - interestingly, it's often referred to by its code name of "Jaguar" more than it is by its version number - added a lot of new features.

All versions of Mac OS X 10.0 require Mac OS 9.1 or later for Classic. Mac OS X versions 10.0.1, 10.0.2, 10.0.3, and 10.0.4 all incorporated bug fixes and performance improvements. The Mac OS X interface looked so much like the Mac OS interface that users assumed everything was done the same, which it wasn't, so users had to unlearn old habits. The Classic environment in 10.0, although much better than in Public Beta, still had strange compatibility problems and quirky behavior. Like the original Mac OS, Mac OS X users' biggest complaint was speed - many felt the code name of "Cheetah" was wildly inaccurate. Mac OS X also provided Cocoa, the descendent of NeXT's very sophisticated OpenSTEP software development environment.

Mac OS X 10.0 also provided all the standard features of a modern operating system - protected memory so programs couldn't corrupt each others' data, preemptive multitasking so programs couldn't hog the processor or lock the entire computer up, device drivers that would be loaded or unloaded as needed, and so on. It incorporated a lot of the feedback provided by people that tried out Mac OS X Public Beta.
