I have a new 15" MacBook Pro Retina Display with a factory 750GB SSD. I thought it might be of value to post my experience in setting the machine up. I generally set up my laptop Macs with the internal drive partitioned into a boot partition and a data partition. This possibly stems from my unix background, but I've been configuring Mac laptops that way since the early PowerBook days and it works well. It really speeds backups and, more importantly, recovery. I use TimeMachine over my home WiFi to a local SAN and also do periodic clones of both partitions with Carbon Copy Cloner (thank you Mike Bombich). The first thing I did on the new MBPr was to clone the virgin OS partition from the MBPr onto a clean external drive. I was at the Apple Store yesterday buying a Thunderbolt cable so I could do a target-disk-mode migration from my 17" MBP. While there I had a conversation with a "Genius" who told me that, on an SSD machine, the recovery partition is actually a completely separate volume from the main 750GB SSD. Meaning I could reformat the SSD and not lose the recovery partition. WRONG! Reformatting the drive into my two partitions destroyed the recovery partition. OK. No big deal. I'll just re-download the Lion installer from the App store, re-install the OS, thereby re-creating the recovery partition and start again. Great plan. Didn't work. I downloaded the Lion installer from the App store on the 17" MBP (which is running 10.7.4), built a USB key with it and proceeded to boot the MBPr with it. No joy. The MBPr wouldn't boot from the USB OS Install drive. It turns out it wouldn't boot from the working boot disk on the 17" connected in target disk mode either. The result is an "X" with no other dialog on screen. This is the most recent, fully-updated version of Lion, mind you. I do still have an external HD with a clone of the virgin MBPr boot volume on it so I boot from that. No problem. But when I try to download Lion from the App Store on the MBPr, I get an error dialog saying that the version of Mac OS X (10.7) I'm trying to download is not supported on the computer I'm using. Terrific. I now appear to be hosed. I tried several intervening steps, including a very cool script that downloads and installs a new recovery partition. That works great, except that the MBPr won't boot from that recovery partition either. So I was right. I really am hosed. So I wipe the MBPr hard drive and restart with Command-R. Since there's no recovery partition, I eventually get directed to Apple's Internet Recovery. This is really quite magical. It takes several hours but when I wake this morning, the MBPr now has a factory-fresh Lion install on it, complete with recovery partition. Yay. I use Drive Genius to adjust the size of the boot partition and add a new data partition. And I'm back in business with two visible partitions and an invisible recovery partition which the MBPr will actually boot from. More yay. This morning I had a long conversation with Apple Support. After several rounds of support techs making ludicrous suggestions (like "the new MBPr may not be able to boot from USB") I finally got a supervisor who believes that the version of Lion currently available for download on the App Store is 10.7.2. Typically one downloads that version and then runs an update to 10.7.4. Trouble is, the MBPr will not boot from 10.7.2. I like to carry an OS installer on a thumb drive, since I travel a lot for work and sometimes connectivity is terrible in other countries. Hell sometimes connectivity is terrible in this country. At this point that can't happen. At least for now, there's no distributed version of Lion that can be used to install an OS on a new MBPr. You CAN download the recovery partition tool and then use that to do an OS install. And you can use Internet Recovery. We'll see how long it takes Apple to update the version of Lion in the App Store.
