A friend recently gave me his old MacBook Pro with Ubuntu 16.04 on it. I really want to install Mac OS on it so I downloaded an installer and ran it on a USB. I got the installer up and running but it would not recognize the internal hard drive because it was formatted to ext4. How can I change the hard disk back to Mac OS Extended??

Head over to ubuntu.com and download Ubuntu. Then follow these instructions to burn the downloaded ISO image to a flash drive. Once that's done reboot the computer and boot to the USB, clicking "try ubuntu" when the option presents itself.
You will need a few packages to add HFS support, so connect the machine to the network, then open a terminal and run:
sudo apt-get install hfsutils hfsprogs
Once the installation process has finished, open gparted and find the ext4 partitions you want to reformat. Right click on them and select Format to -> hfs+.
Follow through on any prompts, and then let the program do its thing. Once it is finished, you're done!

I ended up just erasing the drive because Parted would not let me change the partitions. May 31, 2016 at 2:15
