I recently installed Ubuntu 16.04 on a partition of my Macbook Pro (c. 2016) hard drive and corrupted the boot loader for OSX. I don't use Terminal much, so I am not familiar with all of the commands.
I can boot cleanly in Ubuntu, but can't manage to get a backup of the files on my Apple HFS/HFS+ hard drive partition made through Ubuntu Terminal I've also tried doing this by booting my laptop in Target Disk Mode, connecting it to another Macbook via Thunderbolt 2.0, and using Terminal there.
On the other Mac, I tried dd, cp -av, asr restore, and rsync -av to try to move the files over to an external hard drive with /dev/diskN as my target. For dd I got a permission denied response. For cp it told me that /dev/diskN is not a directory. For asr it told me that file copy is not supported anymore. For rsync it told me that /dev/diskN is not a directory.
In Ubuntu, I've tried sudo -s dd if=/dev/sdaX of=/dev/sdcX which initiates alright, but ends up only copying over 650MB of a 650GB partition.
I've also tried using TestDisk, but haven't figured out how to use it to repair a partition table. It found one error, but didn't give me a clear way to repair it after doing a quick scan of my full 1TB drive.
Please accept my apologies if I am posting this in the wrong place or not describing these issues correctly. My assumption is that there is some combination of a broken partition table and a security or permissions issue with the HFS partition of the drive (though I definitely did not have FileVault turned on). Any help would be greatly appreciated.
