Create recovery partition for 10.10.3 on new hardware

[roiegat]

So we have new Macbook Pros (Mid-2015) and I'm having a hard time getting a recovery partition to work for them. When they first came in I grabbed an OS image and a Recovery Partition. The OS image worked great but the recovery partition doesn't work. When booting up into it with the new systems you get the circle crossed out.

Normally I used auto-dmg and create an OS image that has the recovery partition. I figured the app store yosemite would be updated since the new macs are up. I downloaded the latest version (1.6.18) and tried it. But it won't boot on the new macbook pro (gets that crossed circle again). The OS package I created with this does work on all our hardware very well, but just need something to work with the new equipment.

So any suggestion for creating a 10.10.3 recovery partition that will work on the new macbook pro?

Did you make the OS image with the build they came with or only from the autoDMG/Yosemite installer?

You'll have to make it from the OS it ships with as it's build number is higher than the current retail release of 10.10.3. You can get a fresh image on there by booting to cmd+R and letting it do an internet recovery. Once you do that, you can target disk mode the Mac to pull images off of it.

You might need to mount the recovery partition manually through terminal using the diskutil mount command but once it's mounted you can get an image of that as well. Then in Casper Admin, you can set it to add the recovery partition manually (using the partition tab in the configuration settings) and it will go on. Hope this makes sense and is what you're asking for.

Did both. So first I tried that autoDMG/Yosemite route and that didn't work. That would have been ideal since we use it for all the other hardware.

I used diskutil to capture the OS and the recovery partition from the fresh build on the new machine. But when we deploy that recovery partition to the same machine (or another new machine) it comes up with the circle crossed out. More importatly, it doesn't recognize it as a recovery partition and doesn't allow us to start file vault.

So any suggestions?

@roiegat User "Composer 9.7+" to capture the OS.dmg & recovery partition from the new Mac connected via Target Disk Mode to another, the capture DMG's can then be deployed via Casper Imaging.
