Maybe everyone already knows this. I wanted to install OS Lion and I had made a thumb drive installer months ago, but it would not work. "The installer could not be verified and maybe corrupt." Rather than download the image all over again, I went to the internet archive and download an ISO of the retail Lion installer. But of course I was out of dual layer DVDs to burn it to.

In a long shot I used Raspberry Imager to write the Lion ISO I had downloaded to a thumb drive. Low and behold, it booted and it is installing. I do not know for how long Apple made DVD media to install OS X, but if you can find an ISO of an OS X installer, Raspberry Pi Imager will create a bootable thumb drive from it.

Excellent, that's a good tip for everybody with a more modern Mac and the wish to install later OSes (i think Snow Leopard was the last released on DVD?)

From what I could pickup, Lion was the last version of OS X that Apple distributed a retail DVD installer. I do not remember Lion as being a standout release. What I appreciate about Lion is that it is the oldest OS X that works with iCloud. I have used dotMac/MobileMe/iCloud for 25 years now and it is a very ingrained part of my workflow.

Really? Has there been a retail version of Lion? I can't remember one, I thought Snow Leo was the last. But then I'm not too familiar with later OS X stuff :-)

The iCloud support in Lion certainly is nice, though it's likely to get axed at one point, right? One has no control over that process. :-(
