error, or a
“This re-create of the Install Bone X Yosemite awarding can’t exist verified. It may have been corrupted or tampered with during downloading”
message, or a more vague
“An error occurred while preparing the installation. Endeavour running again”
error message. Sometimes these tin be resolved past simply rebooting and trying to reinstall Os X once 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 date of the Mac tin can be the resolution.

It’southward possible to encounter these errors during basically any blazon of installation attempt in OS X El Capitan or Os X Yosemite, ranging from the standard App Shop update,
using Net 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 Bone X while from an active OS X boot (say, a standard upgrade from the App Store), you lot tin can typically resolve the problem simply by setting the Date & Time on the Mac to be determined automatically.

Set date and time automatically

That method requires the Mac to have agile cyberspace access, even so. If you’re on a computer without cyberspace access, or if you encounter the problem during an alternative OS X installation method and thus can’t access System Preferences,
turning to the Concluding to set the date
is the next option.

To determine if the Concluding date trick can fix those mistake messages and help you to successfully install OS X, you lot’ll need to turn to the control line while at the “Install Bone X” kick bill of fare.

Hitting render, and if the reported date is anything other than the bodily current date, then you’ve almost certainly found the cause of the problem. This may look something like:

Mon Jan nineteen 09:55:15 PST 1984

The unabridged line matters, every bit
the date must be correct in order to install OS 10, specifically the year, because if the engagement prepare is prior to the release of Os X, the error will trigger. Pay special attending to the year as an obvious indicator of something incorrect. If yous notice the date is completely wrong, you can set information technology the electric current date and fourth dimension using a variation of the same terminal command. Y’all now have 2 approaches, set the date via the internet, or set the appointment manually. Setting information technology via the internet is easier:

The transmission engagement format to utilize is a piddling weird, if you’re familiar with the control line you can retrieve it yourself past using date –help, which looks something like “[mm]dd]HH]MM[[cc]yy]”

In simpler terms, that is: Calendar month Date Hr Infinitesimal Year, and it’s entered every bit a solid line with no breaks or spaces betwixt the numbers. For example, to set the appointment as “September 20 2016 at 17:33” you would utilize the following syntax:

date 0920173316

Information technology may await like a random string of numbers but it’s really the month 09, appointment 20, fourth dimension 1733, and year 16, combined.

Set the date and time manually in OS X to circumvent error messages during Mac OS X install

Once you enter the proper engagement and hit return, you can go out out of Terminal and brainstorm the installation process over again as originally intended, and Os X should no longer throw the dodgy sounding mistake messages.

Do annotation that sometimes yous volition see the
“This copy of the Install Bone X Yosemite application can’t be verified. Information technology may accept been corrupted or tampered with during downloading”
error message because the bodily installer was modified or damaged during a download, to be certain that is not the case, always download the Os X installer applications directly from Apple and the App Store, and never from a third party site. As well, sometimes the
“An fault occurred while preparing the installation. Effort running again”
error bulletin will appear and resolve itself with a simple reboot. Nonetheless these two error messages also display when the organization date on the Mac is gear up incorrectly, which is obviously what we’re discussing here.
