Almost simultaneously with the 12.4 iOS 5 beta, Apple has released the first public beta version of iOS and macOS 13 Catalina. Judging by the first reviews, the public test build is almost identical to the second beta versions of iOS and macOS 10.15 13 for developers.

It is worth noting that the public test build of the new Apple operating systems weigh quite a lot: the way iOS 13 weighs about 2 GB, and macOS 10.15 – about 1.5 GB. While downloaded the public test build rather quickly, much delay or low speed at the moment is not observed.

On first impressions or the first public version 13 iOS nor macOS 10.15 are not suitable for everyday use. In the case of mobile operating system there are problems in many third-party applications. Some programs simply to fly, and some cease to operate individual functions or the application freezes completely. A public beta of macOS 10.15, for reviews, also not stable. In addition, at this stage, the OS is slow, and some programs refuse to load.
