I am trying to reset my MacBook Pro, and when I was re-installing the macOS I got this error:

An Error occurred while preparing the installation. Try running this application again.

When I searched the internet I found most of people met this issue when they just click the continue on Eligibility Verification window. The reason for this one is because the date is error, but I checked my date in terminal and it is correct.

I met this error on the About x minutes remaining step, and it was wait a few time when this error shown up.

Ps: It said After 5 minutes remaining when the installation started, but I wait a long time (half an hour) until the error popped up.

Anyone met this problem and has solution?


  • Welcome to Ask Different! :) Can I ask you to edit your question to clarify how it is you're trying to reset your MBP? For example, are you going into Recovery mode or doing something else? Also, it may be worth you adding the exact details of your MBP. – Monomeeth Sep 3 '17 at 12:12
  • Did you solve this? I have the exact same problem and all suggestions to set my date to today do not work. Iam at a loss how to fix this. – Georgi Petrov Mar 24 '18 at 3:38
