New features, as we said, are fairly thin on the ground, but there are some goodies in there. Disk Utility has lost some features that we will miss, such as the ability to repair permissions and create RAID disks. Spotlight remains – in our subjective experience – sluggish, as does the Mac App Store. (Still, our optimism here points to another pleasing development: the speed and frequency of updates we’ve seen since El Cap first launched.)
El Capitan is certainly faster than Yosemite, but it’s dogged by reliability issues. We hoped that El Capitan would be a sort of modern Snow Leopard: an OS with relatively few new features but much faster and more reliable performance compared to its predecessor.
Some features remain buggy and unreliable four months on.
