aren't able to back up and reformat, try the following steps to resize the partition where you want to install OS X: Restart your Mac from your usual startup disk. Open Disk Utility, located in /Applications/Utilities/ . Select the disk where the volume you intend to upgrade resides. This usually starts with a number representing the total size of the disk. Click the Partition tab. Click and drag the resize corner of your intended install partition to make the size slightly smaller. The blue portion represents used data space. The partition only needs to be approximately 128MB smaller than it was before resizing but it needs to be larger than the blue portion. Example Before: After: Click Apply. When the partition resizing is complete, quit Disk Utility and install OSX. After the OS X installation is complete, you can use Disk Utility to resize the partition back to its original size by dragging the resize corner to make the partition as large as it was before.

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 https://support.apple.com/en-us/HT203482 persistent, then you may find that modifying the system 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 http://osxdaily.com/2015/01/19/fix-os-x-install-errors-cant-be-verified-error-occurred-preparing-mac/ X while from an active OS X boot (say, a standard upgrade 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, becau

Tech 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 some time now, I os x 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 across while upgrading their machines occurs not be installed 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 Administrators use. While this can be true, the Terminal can be your f

In recovery mode I erased the main hard drive so I can have a clean install. Then I selected "Install OS X Maverics" and after asking my permission to "verify the installation with apple" I got this error: An error occurred while preparing the installation. Try running this application again. I restarted, and then it started the "Internet Recovery" mode, which now gives me the option to install OS X Mountain Lion instead of Mavericks, and gives me the same error every time. I've checked the date through the terminal, and it is correct, but I am not in "PDT", I'm in "IDT" time zone. mavericks error install share|improve this question edited Dec 29 '14 at 18:57 daniel Azuelos 5,1281658 asked Oct 2 '14 at 10:21 Shock E. 51115 add a comment| 3 Answers 3 active oldest votes up vote 1 down vote Only if you have a Recovery partition intact on the machine will it attempt to recover to the OS that was last installed, otherwise Internet Recovery will recover to the OS your machine shipped with - If you use Internet Recovery to reinstall OS X, it installs the version of OS X that originally came with your computer. After installation is finished, use the Mac App Store to install related updates or later versions of OS X that you have previously purchased. Ref: http://support.apple.co
