The software could not be verified. It may have been corrupted or tampered with during downloading.

I'm having the same problems, i downgraded from lion to snow leopard then wanted to switch back again, after finishing the download the message " the software could not be verified. It may have been corrupted or tampered with during downloading". I tried to delete the install lion icon and when I opened mac store it doesn't have the download or the install button, but the price is indicated so it means i have to buy it again. Also, I deleted the lion in my purchases so when i click on my purchases it says no items purchased.

Please help me. thank you.

I had the same problems as you discribe above. In my opinion there is a problem at the official donload / file. I tried to install an installation package I found via torrent and it worked perfect. If you have already paid the new software you will have no problems at all. Updates work perfect. Thank you.

Hello Camilo,

Don't worry, you can download it as many times as you like. I had to download mine a few times before I got a non corrupt version. If you read the posts above, you'll notice that one solution has been to pause (not stop) the download from time to time (it worked for me at least).

Regarding the other issue regarding the ownership of the software, "unfortunately" it's not really yours, you just have the right to use it. Legally, Apple is the owner of the operating system and by paying and downloading, you are allowed to use it, hence the license of use as opposed to the ownership...

Hope this helps. Regards.

OMG, thank you Peter, i´m sorry i was very upset when i wrote that post.

I understood about the ownership and the licence, thank you again.

but, i don´t understand why there´s a corrupt version, or does anybody knows why?

Regards, and thank you again.

Using secondry click choose "Show Package Contents" open "Contents" folder and then go to "Shared support" and open "Install ESD.dmg" double click on Install Mac OS X Lion and thats it, its will not shows you that error again. It really works.

Thank you, this helped! trying to install mac os x lion on snow leopard via USB 2016

same issue here!

If you bring your Mac to the local Apple Store, they will guide you on Lion installation. Infact Apple Store has local Server where you can download Lion within seconds free of charge!

Strange!

Changing permissions worked for me after multiple downloads. It wasn't enough to use the info panel on the downloaded program but I had to use "sudo chmod -R a+rw ...". Thanks for the tip.

Changing permission did not solve my problem...I'll wait a couple of months before I try again.

what the heck? after waiting so many hours, got a corrupted file? Such a pain to download this thing!

same problem here. I tried to download it several times as you describe above. I tried also with the DVD. nothing happened.. please help

thanks! i already installed a new lion from my friend, so i didnt bother checking on the old one anymore. i just hope i wont be needing to reinstall lion again after this.

it is available on a USB stick but it costs more, this is the cheaper hardware free always accessible option
