It exists solely to define the look and feel of Apple products. Apple’s hidden access to it (Īnd will continue to hide it) because San Francisco simply wasn’t designed for print/DTP use. Incidentally, San Francisco is not available to use as a font in your documents – you won’t find it via the Font Book app or even in the system Fonts folder. We experienced nothing like this in El Capitan.

Compare that to Yosemite: Since its introduction many Mac users have been painfully aware of lags and slowdowns, such as stuttering animations and network connectivity issues. On a subjective level it felt like El Capitan ran like greased lightning on ourĢ015 MacBook Pro.

Our brief and very unscientific benchmark tests showed absolutely no performance difference between Yosemite and El Capitan, which is of course only a beta right now.

We’re also aware that El Capitan a beta, so our results are unscientific at best, and the benchmarking apps haven’t yet been optimised for El Capitan either. GeekBench produced identical results on both operating systems – but we strongly suspect Apple’s achieving the claimed speed-ups by disk cache optimisation, and benchmarking apps are specifically designed to avoid taking this into account. Despite this Apple says that apps in El Capitan will load apps up to 1.4 times faster and switching between apps will be twice as fast.
