Error reinstalling MacOS Sierra - iMac Need help with reinstalling MacOS Sierra I have an iMac (late 2015) which originally came installed with MacOS Sierra. I am trying to reinstall MacOS after accidently erasing Macintosh HD. I've restarted iMac in internet recovery mode and able to reach MacOS Utilities window. After this, i select disk utility. There is an internal disk with title Apple HDD HTS5... In here Macintosh HD is missing and hence I created Macintosh HD partition. I click on Erase and then entered Macintosh HD as Name; Mac OS Journaled as the format. Based on this Macintosh HD partition was created. After creating partition, I go back to MacOS utilities and select Reinstall MacOS. I select installation of MacOS Sierra on Macintosh HD. However, after a few minutes, I get the following error - "An error occurred while preparing the installation. Try running this application again". I tried a few time repeating some of the above steps but wasn't successful. Any guidance to resolve above issue would be great.

What I think has happened is that your file likely got corrupted during the download process and therefore will not install. Put the file into the Trash and empty it. Then do another download. If possible, do not use Wi-Fi as it is much slower. A wired Ethernet connection is much faster and more reliable for these very large downloads.
