the message, "Recovery system creation failed with error -69713 (The booter/recovery partition must be grown by a larger amount)." You may be presented with an option to select which disk is the target for installation. In some situations, the disk you want to upgrade may be labelled "This disk cannot be used to start up your computer." If possible, back up mac os x 10.4 updates and reformat the target disk before installing. If you 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.

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 updating mac os 9 with during downloading" error, or a "This copy of the Install OS X Yosemite how to software update mac application can’t be verified. It may have been corrupted or tampered with during downloading" message, or a more vague "An error occurred os x el capitan update could not be verified 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 https://support.apple.com/en-us/HT203482 error messages are 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 http://osxdaily.com/2015/01/19/fix-os-x-install-errors-cant-be-verified-error-occurred-preparing-mac/ to update or install OS 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

to install 16 Replies A few people who have attempted to install the latest OS X 10.10.3 update have found an issue where the update will take a while to install, and then restart only to stall at boot, followed by loading back to OS X 10.10.2. In some cases this may happen repeatedly, suggesting a fault with your Mac's current setup that is preventing the installation. If you are stuck in this situation, you can overcome the issue through a couple of quick troubleshooting steps. 1. General Troubleshooting First try some general troubleshooting steps such as booting your Mac into Safe Mode, and using Disk Utility to repair your Mac's hard drive and permissions. If there are any drive configuration errors, then these may prevent the update from being applied, and these approaches can reveal or even fix them. 2. Download the Combo updater The updater that is pushed to your system via the App Store is tailored for your Mac, and only includes the files necessary to update it. On the other hand the Combo updater includes all files to update any version of OS X Yosemite, and as such may replace more system files to ensure the update is complete. Download the 10.10.3 Combo updater from here, and then mount the disk image and run the installer package on it. 3. Reinstall OS X While reinstalling OS X may sound extreme, it in fact performs a similar routine as simply using the Combo updater, where it will just replace system files while keeping your personal data and third-party software intact. It will simply replace all Apple-provided system files and thereby overwrite any problematic ones that may be contributing to this error: Reboot your Mac and hold Command-R at the boot chimes to load Recovery Mode Choose the option to install OS X Follow the on-screen instructions to install OS X to your boot drive. This process will install a prior version of Yosemite to your Mac, but immediately after doing this, be sure you access Software Update and apply the OS X 10.10.3 update. 4. Format and restore from backup A final issue may be if severe formatting and drive setup problems are preventing the update from proceeding. If this is the case, then you may also be experiencing slowdowns and other faults w
