How do I mount my OSX partition from Ubuntu?

Question

I'm currently dual booting OSX 10.13.3 and ubuntu 16.04. But today i think i messsed up my kernel cache and i could no longer boot OSX. I need to mount my OSX partition from ubuntu and manually delete the kernel cache. So I installed hfslus and i tried to mount, but it failed.

➜ sudo fdisk -l

My mount attempt

 ➜ sudo mount -t hfsplus /dev/nvme0n1p3 /mnt/macdrive
[sudo] password for seun: 
mount: wrong fs type, bad option, bad superblock on /dev/nvme0n1p3,
   missing codepage or helper program, or other error

   In some cases useful info is found in syslog - try
   dmesg | tail or so.

I checked syslog and found:

➜ dmesg -wH | grep "hfsplus"
[Feb10 11:00] hfsplus: unable to find HFS+ superblock
[Feb10 11:11] hfsplus: unable to find HFS+ superblock
