I accidentally removed the Mac App from my Mac Mini while removing the iTunes 10.5 Beta. How can I reinstall the Mac App Store?
oh, good question. Maybe install a basic Lion system onto an external HD and copy the app from there? Or you don't have a backup like Time Machine or anything similar, do you?
Maybe someone with an identical version of the OS can zip the file and send it to you.
I think that whatever way you wanna do it, copying the app from one Mac to another should work. As long as the OS versions match of course...
