I installed Ubuntu on my 13-inch retina macbook pro (late 2013) and decided to erase OS X and replace with Ubuntu. I regret doing this since now my wifi isn't working (pretty sure it's a driver issue), and it's really slow to boot and there are some other quirks as well.

My question is how can I wipe Ubuntu and reinstall OS X. I rebooted my machine and held Command-R to reinstall Mavericks, but when it came time to choose a disk, there were none to choose from. I guess this makes sense since I assigned the entire hard disk to Ubuntu, but I would really like to reverse this.

Any feedback would be greatly appreciated, and if you have any idea what I could do about the wifi that would be helpful as well, since I really do want to switch to Ubuntu I've just been experiencing so many weird hiccups and bugs.

Thanks in advance!

Your Mac is new enough that it should be able to install the OS from the Internet, with no recovery partition needed on the hard disk. So you should be able to proceed with the recovery without choosing a disk to boot from.

  • I don't think it makes me choose a disk to boot "from", but a disk to download OSX "onto".

  • OK, you may need to use Disk Utility to wipe the existing partition on the disk and create a new one, if you can get that far in the process.

  • Ya that's probably right but I'm not sure how to partition the hard disk properly on Ubuntu.

  • I wouldn't try to use Ubuntu to do it, I'd run the OS X Disk Utility from the installation screen and use that to remove all partitions and then create a new one.
