iLife11 won't install

Wow that was the answer. i tried everything to install ilife 11 and it would not install. i changed the date to 2010 and it installed. Thanks for posting this answer. i can't believe that a company would play a game like this. Instead of tricking people into going and buying a new laptop, they make people like me want to NEVER buy another apple laptop.

It is one of Apple's ways to make software safe. Any installer has to be signed by a valid developer certificate, and the certificates expire after three years. This way you will not install software by developers whose certificate has been revoked. That is no problem for software purchased from the AppStore, because the certificates are updated, but you will have the same problem with all older software on CDs, or DVDs, because the certificate will no longer be valid. But you rarely should need to reinstall from the original media anyway, unless you wipe the drive. Usually reinstalling by migrating from a Time Machine backup or bootable clone is much faster.

Update to 10.6.8 and then give it a shot.

I have the same problem as Lori. I get the same error message. I am running 10.6.8.

What did you do to fix the problem?

I should clarify - I am running Snow Leopard 10.6.8

There should be an update called "Apple Installer" or something along those lines. This update will allow you to install iLife 2011 on 10.6.8 or later.

I just came across this error while performing a fresh install of snow leopard on a 2010 iMac. For me it was the application DVD, but this error may also show up for xCode from what I understand. After some research, I discovered the error stems from an expired cyrtography certification. Was rather annoyed that my restoration disc shipped with a $1700 computer has an expiration date, but this is not the proper time for that rant.

The "fix" is rather easy. Just go into your system preferences and set the date back to before the cert expires. I used some random date in 2010 to be safe. The installer should work correctly now. After installation, just reset your date to the current date.

Thanks

it worked for me... I just did a fresh install of a snow Leopard in my 4 years old MBP and after I set the date as 08/13/2011, I could install, iLife 11... before it gave an error

Just had this occur with iLife 11 and changing the clock solved the problem.

Thanks - it worked for me too.

Changed the year back to 2010 and it installed fine.

iLife 11 on clean install of 10.6.3 on older Macbook Pro

It worked on my Macbook white! I'm using snow leopard. Thanks a lot!

Hey, Mike:

First off, thanks for the tip! Same problem here; wiping a Snow Leopard machine down and re-installing. Reset the date to when I bought the machine in Oct 2010, now everything's hunky dory. How the heck did you discover this anyway?

Second: seriously, Apple, ***???

Third: when I tried to sign in to this page to comment using Safari, I got a warning saying the certificate for this page couldn't be trusted. Major lulz, there.

Thanks again for the help.

It's not a game. Given that you're the first person to add to this thread in five years, it's not like it would be a very profitable game either. it's a minor glitch.
