  1. I am running Mac OS X 10.6.8 I couldn't change the time and date in terminal so i just changed it in time and date preferences and it's now working!!! Thank You Friend!! Today is June 30 2018 .

  2. hi, i have a macbbok 12 inch and no have usb port, when im install macos high sierra "apple.com/support -3001f" error, what i have to do? sometime i have a error APFS.

  3. When I tried to update to high Sierra edition the same problem happened but the massage is ( the additional component needed to install OS X can’ t be found)
    So how can I fix this problem?
    Best regards.

  4. Very useful tip. Thanks a lot for sharing this trick. I was trying to install the OS in a 2011 Imac HD with windows installed. With disk utility I created a new fresh partition and was having lots of problems to install OS. With you tip the installation moved forward and now the Imac is running El Captain flawlessly. Thanks again.

  5. I already backup my files to my portable hard drive. Unfortunately, I forgot to adjust time/date and forgot to insert bootable USB. When I tried to use your methods step by step, the following numbers won't work (010100002016, 0328015315, 110110532016, etc.) . 2 years ago, I'm successfully done my IMAC reformat. Today, the 2nd time of reformatting seems that I forgot it. is it possible to bring it back alive? What should I do? I feel panic, struggling and heart tearing-apart. Is there any easy solution other than this? Would you please reply it to me step by step.

  6. can you please help me, it's still not working. I have a 2010 MacBook air which came with Snow leopard. On September 10 I updated it to El Capitan, then on September 11 I factory reset or erased everything on my hard drive using recovery mode. Now when I try to reinstall OS X it keeps on giving me that error. I tried all the dates. But nothing so far..

  7. I just want to thank you so much, not only for making this but also for leaving this up. I was able to fix out macbook air easily with your help. THANK YOU. I will be sharing easy steps with my friends and subscribing. You are very kind. Thank you.

  8. Help me ….please I have formatted my 250gb SSD and try installing mac os x lion but downloading paused in installer log and says chunk 22of 449 not found & " chunk validation failed and keeps retrying" but nothing happens

  9. Hi sir.. When i try to enter my email add, it keeps saying that " there was an error connecting to the apple id server".. Pls help, thanks..

  10. Wasted 3 hours going the wrong ways trying to sort this problem until I stumbled upon this solution. Worked a dream for me … along with Reggie Buggs tip of date entry (put in 010100002016, regardless of today's date 121416322018). El Capitan now up and running! Thank you so much to Easy Steps (and Ronnie Buggs).

  11. DO NOT USE THE CURRENT DATE: when i used the current date it did not work but when i changed the year to 2015 it worked like a charm, here's the date I changed it to BTW (1220122315)

  12. Thanks! I thought it was a date/ time issue! I just put in date and the numbers instead of putting a space in there. Thanks!

  13. Terminal command "Date 0101000016" worked for me on Yosemite on a Fusion VM even in 2019. It also worked on a El Capitan on a physical imac in 2018. Strange but happy to find the answer. Thank you for a simple to follow video.

  14. Thank you so much for this video! Was very helpful was not sure how I was going to fix the Macbook. Problem solved in 2019! Many thanks!

  15. Thanks heaps! I just wasted an hour trying everything I could think of before searching and finding this video. I would have wasted so much more time trying to sort it out by recreating bootable USBs that would have kept failing – thank you so much.

  16. Thank You for such a well explained tutorial. I spent 3 days with Apple Care Support from the Phillipines and he could not help me out with this error. We tried downloading high sierra, sierra, el capitan and what not thinking it was corrupt.

    He asked me to take it to apple store and repair but out of luck i found this video and you have helped me save time and money to take it to Apple.

    Thank You Again Sir!

  17. Super helpful. Thank you! I had to tweak the date to run with single digit month, day and add 0 for time. 0505085019 and it worked!

  18. Thanks a ton! I bought an old 2011 macbook pro without a battery, and I couldn't manage to install any copy, this fixed the issue.

  19. I was installing El Captain. My date was correct. I rolled the date back about a month after El Captain release date and then it would work. Wouldn’t have been able to do it without this video. Thank you!!!!!! Much love.

  20. Thank you, Thank you, Thank you !
    You're the only person who describes the problem & solution really clearly which really helped me fix my Macbook.
