When the giant of Apple announced the availability of iOS 13 (and most of the new versions of its operating systems), mentioned that the developer beta would be released that day, while the public beta would be during the month of July.
But it seems that Apple the desire that you can try the new versions of their operating systems yourself, because today has officially released the public betas of iOS 13, iPadOS and macOS Catalina So anyone can try them.
The installation method is really simple, but before taking the steps, we recommend that you make a backup of your personal data and files, either on iCloud, iTunes or through Time Machine, in addition to accepting and agreeing that These versions are trial and may not be compatible with your current applications, consume more battery, leave you incommunicado or give errors.
Once the above is accepted, only you must open Safari from your iPhone, iPad or Mac, and go to the page beta.apple.com. Once logged in, you just have to log in with your Apple ID and then select the operating system you want to test.
In the case of being iOS 13 or iPadOS, you will only have to download and install a profile, restart the computer and then go to the menu of configurationselect general and later Software update. There should appear the notice that it is available to download a new update.
In the case of macOS, after logging in with the Apple ID, you will proceed to download an application, which you must install. Once installed, you should see the notice that you have a new update available.
Personal data should not be deleted when updating, but we also recommend making a backup.
