I'm trying to dual boot Lubuntu with macOS Sierra.

I boot using a USB flash drive, select "Try without installing", and when I launch GParted, see about 50GB unallocated space.

However, GParted extended partition option is grayed out.

I'm not a Linux admin by any means, not even close, so not sure what's going on here. See screenshot here


This is a GPT disk. There are no extended partitions on GPT. You can create almost unlimited number of primary partitions.

So create as many primary partitions as you need.

  • I'd like to create an exFAT partition for sharing data between Mac and Lubuntu but that option is disabled as well. – Abhijit Sarkar Aug 9 '17 at 7:48
  • @AbhijitSarkar Create a NTFS partition. – user692175 Aug 9 '17 at 7:49
  • gparted doesn't support exfat. You can format a partition to exfat in CLI. You can easily find a solution at AU. – Pilot6 Aug 9 '17 at 7:49
  • Well, the partitioning worked, but exfat failed miserably. I've opened another question for that, will accept your answer for this one. – Abhijit Sarkar Aug 9 '17 at 11:13
  • @MichaelBay There are no free macOS drivers that support NTFS. – Abhijit Sarkar Aug 9 '17 at 11:14
