I have a new MAC OS X, and Im trying to reinstall the whole system, but when its reach to the the Apple ID and password. An error shows saying This item is temporally unavailable , please try again later

Solutions I used:

1_ On reinstallation of OS X , The error "This item is Temporary Unvailable " is getting because the Apple ID you are using to login is not linked to the Apple OS on your computer . To solve this problem follow the steps :

Click on the choice GET HELP ONLINE on screen

Then safari opens up on clicking

Next Go to iCloud and sign in with Apple ID you were trying to login with

After sign in install the OS X , and Use the same Apple ID that was used signin on iCloud.

2_ The problem was that the old Mac did not have its date set correctly.

1. Hold Option (ALT) + Command + R at Mac startup to start internet recovery

2. Going into Utilities > Terminal starts the recovery terminal

3. Run date mmddHHMMyy - this solves the problem (date must be in PST!)

4. Run csrutil enable

5. Run csrutil clear

6. Exit the recovery terminal and continue OS X installation normally.

Number 4 & 5 shows error

Not of these solution was approval.
