X. Digging a bit, it turned out that the reason is that when the clock has been reset, this (DRM?) verification fails without specifying the reason.To fix, go into the Terminal and manually set the time to current.The format is date mmddHHMMyyyyThat is, day of month, day, hour, minute, year, e.g.date 040310182013for April 3rd, 2013 at 10:18Also, if this was helpful to you, consider paying it forward by making someone else's day better, making a blog post about something that you had to figure out for yourself, as well, participating in an online group to help others (like the Ask Different site for Apple questions) or flat out kissing someone who is short of kisses.

Tip: ‘An Error Occurred While Preparing the Installation’ Fix Monday, July 6th, 2015 | Author: OWC Robert J. Having worked in Technical Support here at OWC for https://www.youtube.com/watch?v=Cf4TzZt24-M some time now, I have helped customers handle many different types of errors and problems that they have come across. Some such as, “The disk you inserted is not readable by this computer,” might have simple solutions like formatting the disk, and some are more difficult such as “My Mac keeps freezing. Help!”One error that customers often come http://blog.macsales.com/31640-tech-tip-an-error-occurred-while-preparing-the-installation-fix across while upgrading their machines occurs during the re-installation of OS X, and it has a relatively simple fix.Once booted into the recovery partition and selecting “Reinstall OS X”, the “Eligibility Verification” window shows up. The error occurs as soon as you click “continue”. An unspecified error shows up which states "An Error occurred while preparing the installation. Try running this application again." Upon doing so, the same exact error pops up. Nothing has been done to have this occur, so what exactly is going on?While this can be frustrating, something quite simple is going on in the background that needs to be addressed. One of the checks that occur during “Eligibility Verification” is to see what time the machine thinks it is. If the computer is reporting the wrong time, an error will occur.While there is a simple fix, it does require using the Terminal to accomplish. Many users might be wary of the Terminal, feeling like something could break and that it’s something only hackers and System Admini
attempted installation of OS X El Capitan or OS X Yosemite are the "This copy of the Install OS X El Capitan application can’t be verified. It may have been corrupted or tampered with during downloading" error, or http://osxdaily.com/2015/01/19/fix-os-x-install-errors-cant-be-verified-error-occurred-preparing-mac/ a "This copy of the Install OS X Yosemite application can’t be verified. It may have http://diskmakerx.com/faq/ been corrupted or tampered with during downloading" message, or a more vague "An error occurred while preparing the installation. Try running again" error message. Sometimes these can be resolved by simply rebooting and trying to reinstall OS X again (or re-downloading the OS X installer if it was damaged), but if the error messages are persistent, then you may find that modifying the system os x date of the Mac can be the resolution. It's possible to encounter these errors during basically any type of installation attempt in OS X El Capitan or OS X Yosemite, ranging from the standard App Store update, using Internet Recovery, to clean installs, and using a bootable installer volume on a target Mac. If you run into either error message while trying to update or install OS X while from an active OS X boot (say, a standard upgrade os x mountain from the App Store), you can typically resolve the problem simply by setting the Date & Time on the Mac to be determined automatically. To do this, go to the Apple menu > System Preferences > Date & Time, and be sure the "Set date and time automatically" option is checked: That method requires the Mac to have active internet access, however. If you're on a computer without internet access, or if you encounter the problem during an alternative OS X installation method and thus can't access System Preferences, turning to the Terminal to set the date is the next option. To determine if the Terminal date trick can fix those error messages and help you to successfully install OS X, you'll need to turn to the command line while at the "Install OS X" boot menu. Pull down the "Utilities" menu option and choose "Terminal", then type the following command into the prompt: date Hit return, and if the reported date is anything other than the actual current date, then you've almost certainly found the cause of the problem. This may look something like: Mon Jan 19 09:55:15 PST 1984 The entire line matters, as the date must be correct in order to install OS X, specifically the year, because if the date set is prior to the release of OS X, the error will trigger. Pay special attention to the year as an o
could not be created because of an error: An error occured: -10006.” This happens sometimes when creating the install disk because a false mount is created as some point. Basically, a false mount is a folder created with the same name as your Install drive, and that makes the Install disk adopt the same name with "1" at the end, i.e. "Install Mac OS Sierra 1". If this error happens: in Finder, click on Go > Go to Folder menu ; Type /Volumes/ If a folder (not a disk !) is named "Install macOS Sierra", "Install OS X Yosemite", or "Install OS X El Capitan", delete the folder (you may need admin rights, thus type your admin name and password). Reboot your Mac Try again. That should do it. I will try to fix it in a future version (if I manage to get why this happens sometimes in some configurations… "This copy of the Install OS X [OS X Name] application can’t be verified.

Due to an expiration of OS X App Store certificates, installers of OS X downloaded prior to February 14th of 2016 can't be used to re-install OS X without encoutering this error.
