Macbook pro help
So I have 2009 pro and it was running the latest OS and tonight I got a the update from the app store, i downloaded it and waited for it to install and restart. But it didn't install, a message popped up saying "there was a error installing the update click "restart" so about a half hour passes and my battery dies. So now it boots up to the back up from Time Machine, download new OS (i started too but it said 7 hours remained)
But I have a 2011 iMac running the updated OS and I last backed it up today, Can I take the iMac backup and use it on the Pro?
