I'm getting the error "Before installing OS X Mavericks, this system requires MacBook Air Flash Storage Firmware Update 1.1. Click on the Updates button in the Mac App Store to install the update." even though I've applied the firmware update and there aren't any updates (besides Mavericks) in the Mac App Store. Any help?
Lots of people have reported having to install that thing more than once.
When you installed it, after reboot, did you absolutely get a window saying it was successful? (for me, the window took 45-60 seconds to pop up, and it failed twice before it worked (didn't want to install on battery)).
Try reloading the updates section of the Mac App Store again, and again.
Happened to me, too. With the exception I have FileVault enabled. Contacted Apple Support and looking forward to resolve this issue. Otherwise I'm stuck with Mountain Lion. Can anybody confirm this has something to do with FileVault, actually?
It happened to me too. Apple -> Software update and the patch was still there. So I installed it again. Great success; now waiting on the Maverick download.
