Apple Finally Updates OS X Lion on Mac App Store to 10.7.1

[Yuusharo]

I've already installed 10.7 and the update 10.7.1 but I want to have a bootable DVD with 10.7.1 like others here.

So I tried re-downloading from the App-Store purchases section by holding down "option" key and it started to download 3.75 GB but when it finished it said it couldn't install as 10.7.1 was already installed and now i can't find the downloaded file anywhere....

bummer....Is there anyway to save this file to make a bootable USB or DVD with the full 10.7.1 ?

The installer *should* be in your /Applications/ folder called "Install Mac OS X Lion" or something like that. If not, it's possible the installer already deleted itself thinking you were already up to date.

If it's gone, you'll have to redownload it again (you can do so as many times as you want, provided your ISP doesn't cap you). Once it's saved, you can right click and select "Show Package Contents." Somewhere in the resources you'll find the "InstallESD.dmg" file. Copy that to your desktop. Then, use Disk Utility to "restore" that dmg file to a USB key or burn it to a DVD.

This trick only works on machines prior to the Macbook Air and Mac mini 2011 models for now.

There are different build trains within Apple that are strictly for the new hardware at the moment. This happens all the time and you have to get used to it.
...
It's just early days just now. Apple will consolidate the trains in a future release, most likely when iCloud is ready for public consumption.

I agree. Usually divergent build paths caused by new hardware support are rolled back together at the next point update. But 10.7.1 has the appearance of a quick release meant to fix only a few high priority issues; I'd expect 10.7.2 to offer a lot more, including reconciling the divergent build paths.

Thanks

Thank you both for doing this! My first download from the MAS was corrupted, and this was one of the top results when I searched for the md5 for 10.7.1 to make sure that another 4GB of downloading was not wasted.

Mac OS X 10.7.1 (Build 11B26) from the MAS contains iTunes v10.4.0 (says the Info.plist). Apple updated also the "BaseSystem.dmg" and the "/System/" folder on the InstallESD.dmg to Build 11B26.

I got the following checksums for my InstallESD.dmg:
SHA-1: 7680f93a44f72dfdb0e3c15e683a8fc506758e42
MD5: 2530e25b669104dad9476653be461297

...in a Terminal window.

Please publish your checksums, if possible! Thank you!

Btw, yes it is Mac OS X (not OS X), because Apple called the Lion installer "Install Mac OS X Lion.app".

Edit: Thank you "blackburn" for the checksums!
