Kernel panic and HDD format questions

Hmm, thank you Dan. If that SSHD drive had Mojave on it, then it is no surprise that it crashed in my 2010 15” MBP, I suppose. Unless I am misinformed, the 820-2850 board in the 2010 can only go up as high as High Sierra, right?

The SSHD came out of a 2011 machine, which packed it in due to the GPU. Do the 2011 MBPs support Mojave? And is that the reason the SSHD was formatted as a Logical volume group?

@jurgenkoppen - Sorry I jumped to a higher version on you. I don't use High Sierra I either stick with Sierra or jump to Mojave.

Frankly, I would go with Sierra here but as you updated to High Sierra you are caught on a rough version ;-{ Mojave is better but not so good for SATA based systems.

Then you have the Apple supported issue: Technically Apple won't support issues under Mojave with the older Mac's, but you can install it on the older Mac systems using DosDude1. Even still I would stick with Sierra unless you are playing around and don't have a newer system to run it on.

As for your 'Logical Volume group' I think you're just seeing Disc Warrior's jargon for the volume type. I would just stick with Apples Disk Utility. Unless You have an updated version of Disc Warrior I would recommend you throw it into a dusty drawer and just stick with the Apple tools. There is just too much canes over the last few years to trust any 3rd party tools, more so on older ones.

Thank you Dan for shedding some light and your take on Sierra, High Sierra and Mojave.

I’m not that interested in Mojave, because I like the " older" 2010 MBP’s since they do not shed keyboards and fry GPUs as the post 2010 machines do.

Well, I must check and see what OS is actually on the original SSHD which came in my buddy's fried 2011. But what ever OS is on there, since I am putting him onto a 2010 MBP, I will transfer his data then to a Sierra OS SSD. Does that sound right to you? Also, the info : " Type: Logical Volume Group" and "Format: Logical Partition" I read on the Disc Utility which I used to prep SSDs , and this Disc Utility is just the standard Yosemite program came with the OS.

I just did not know what to make of it....Before that I had put my friends original SSHD on Disc Utility in a Snow Leopard machine, it just said " unsupported format".

So I checked the SSHD OS which I am trying to transfer to a2010 machine, and it is El Capitan. So all should be well, as I am migrating its data now onto a fresh install El Capitan SSD, to keep his sytem the same, only on a more reliable 2010 machine.

OK I think I'm getting it ;-} You have three different file systems at play! The oldest being what Leopard supported the older HFS, the newer HFS+ and now we have APFS! My brain is hurting going so far back. The unsupported file system was because you had HFS on the drive not HFS+

It been awhile since I've installed a SSHD so I'm rusty on how it looks I think you're just seeing the logical partition as the onboard SSD is involved.

The best thing here is to make a backup and reformat the drive with HFS+ and then install Sierra or older OS onto the drive.

Don't go with High Sierra it has too many issues!

As far as your reasons the 2011 models do have an issue with the GPU's, but the 2012 are very sable and don't have the same sensitivity with their GPU's. It still comes downs to what you run on the system. It's not a gamers box or one that can handle heavy graphical stuff. So you do need to be mindful of that.

The late 2013 retinas to 2015 are all OK, but the 2016 onward (2018) are just not reliable! Between the keyboard and the display cables.
