If you wish to be one of the first to install iOS 10 or MacOS Sierra, this publication is for you. But before we start, you should know that beta products may present bugs. 
Έτσι για να μην συμβεί κανένα λάθος και δεν μπορείτε να "χαμηλώσετε" έκδοση λειτουργικού συστήματος αργότερα βεβαιωθείτε ότι:
1. You have created at least one backup copy of it devicethrough iTunes or your computer.
2. Do not use your main device
3. Wait a short battery life and battery performance
If after all that we mentioned above you still want her upgrade σε έκδοση beta, διαβάστε παρακάτω, αν όχι αλλάξτε σελίδα και... πάντα φίλοι.
For all consumers (upgrade will be available in July)
Κατ 'αρχάς, για να μπείτε στο Apple Software Beta Program you will need to use to connect your Apple ID.
You will then have to sign up for both iOS and MacOS Sierra to be selected by Apple. Follow the instructions carefully, and you will end up with a brilliant new beta profile for your phone and PC.
Then you have to wait, because unfortunately the public beta program for iOS 10 and MacOS Sierra starts in July.
If you are a developer (update is already available)
Είναι πολύ πιο εύκολο, αλλά και πιο ακριβό, γιατί θα πρέπει να εγγραφείτε στο Apple Developer Program which costs $99 per year. Probably not worth it if you just want the beta.
Just log in to Apple Developer Download Center and follow the instructions.
