"The installer payload failed signature check?"

Question

"The installer payload failed signature check?"

Product: MacBook Pro 13-inch, mid 2012
Specs:

- Processor: 2.5 GHz Intel Core i5

- Memory: 4 GB 1600 MHz DDR3

- Graphics: Intel HD Graphics 4000 384 MB

- Software: Mac OS X Lion 10.7.5 (11G63)

I keep getting the error message "The installer payload failed signature check" whenever I try updating to macOS Sierra. The message pops up a minute or so after initiating the install. I recently had my MacBook Pro repaired at a local repair shop and so my OS was reverted back to what was originally installed. Before having it repaired I was running Sierra just fine. I've tried using the ntpdate -u time.apple.com Terminal prompt but whenever I enter it I get the error "Can't adjust the time of day: Operation not permitted." I've also tried reinstalling OS X Lion but nothing changed. Still get the same error message. Any help would be appreciated!

MacBook Pro (13-inch Mid 2012), Mac OS X (10.7.5)

Hi,

Try using Terminal in Recovery Mode to fix the date.

Do you have access to the "regular" recovery partition? (The one you access by pressing cmd+R during boot)

Yes, but in that I got the "ntpdate: command not found" from Terminal after trying to update the date/time.

Another approach is to set the date manually from the command line by using the “date” command string, where date is in the [mm][dd]HH]MM[yy] format, which is Month Date Hour Minute Year without any separation. This looks something like:

date 0712122318

For that example, it would set the date as “July 12 2018 at 12:23”.

Just tried that and got this in Terminal:

date: bind: Permission denied

date: settimeofday (timeval): Operation not permitted

The error you are encountering is due to the fact your Mac cannot contact Apple's servers.

I recently had my MacBook Pro repaired at a local repair shop

Bring it back to them and tell them to fix it. Hopefully that "local repair shop" was an Authorized Apple repair facility. If it was not, Contact Support to find one. Never let anyone other than Apple repair an Apple product.
