I've followed the steps to create a bootable USB with the OS X Mavericks installer and I hit the same error every time.
- Boot using the USB
- Select the Install option
- Accept the T&C
- Select the location for installation (a new blank SSD to replace my suspect old stss andard SATA drive)
- Begin the Installation
- Starts to run, then I get the same error telling me that the version of Mavericks has either been downloaded incorrectly or has been tampered with
- Press "OK" and the installation terminates.
I've downloaded it three times to my iMac, already running Mavericks.
What am I doing wrong?
MacBook
Pro, OS X Mavericks (10.9)
