Mac OS X – The recovery server could not be contacted.

I believe some of your guys may experience the following error when trying to reinstall Mac OS X in recovery mode.

There are two possible reason cause above error.

Reason 1:- Wi-Fi connection is not stable and keeps disconnecting.

Reason 2:- System time on your Mac is incorrect.
To fix system time issue in recovery mode

  1. Open up a Terminal from the utilities menu
  2. Enter the following command
ntpdate -u time.apple.com
  1. Try to install your Mac OS X again. It should work as expected.

Apps to Write NTFS Drives on a Mac OS X

I believe most of the Mac user know by default Mac OS only can read from Windows-formatted NTFS drives. To write NTFS disk, you need to have 3rd party software.

When you google it, first page of google sure will show you the two best paid version of NTFS app which is Paragon NTFS for Mac and Tuxera.

If you look for free version of NTFS app, i would recommend an application called Mounty for NTFS which available for free. You can get it here right now.  I have tested this apps, it is easy to use and the performance not bad.

If you have any others good free apps, please do not hesitate to share with me. 🙂
