So... I had to change out a failed HD of a 2009 MacBook Pro. The iFixIt site suggested disconnecting the battery leads as a precaution. The entire swap (to a shiny new SSD) took about 15 minutes - first screw out to last screw in. Woo Hoo!
Then it's time to install OS X. Insert my (untested) bootable OS X USB drive.
Boot from it. Check!
Run Disk Utility and erase (format) new SSD. Check!
Run "Install OS X" and choose new partition. Check!
Error! Something like "This OS X installation file cannot be verified. It may have been tampered with or corrupted." Damn!
I repeat a couple times with identical results.
I spend 45 minutes copying the original install file from my NAS to my iMac and recreate the USB drive. Fail - with the same message.
I spend 60 minutes re-downloading the install file from Apple and recreate the USB drive. Fail - with the same message.
30 seconds with Google (which I obviously should have done first) reveals that this error is common when the date on the Mac is way off - which happens when you disconnect the battery!
Thankfully after setting the date via terminal the rest of the install and recovery from TimeMachine went smoothly.
