I'm currently trying to dual boot Arch alongside MacOS (Sierra 10.12.2) on my mid 2012 MacBook Pro using rEFInd. It's possible for me to boot into my Mac partition via rEFInd if I don't add a menuentry for arch but when I do the menu doesn't show up. I kept testing and it turns out if I comment out the volume specification in the "Arch Linux" stanza the menu will show and I can boot into my mac but when trying to boot into Arch I get told vmlinuz-linux couldn't be found. I can get the exact output if that would help.
Here is some additional info that you guys might find helpful.

Same problem happened to me months ago.
The Wired thing was it showed partition like /dev/sdc1 when I booted with USB stick, but after installed, it showed error like /dev/sda1.
So after installed, I checked the partition and corrected the /etc/fstab file. More specifically, I changed all of the labels from /dev/sdc* to /dev/sda*.
It's MBP 2015 Mid, which is also dual boot and works perfectly.

Thanks for the response. I don't think I have that issue. Here's my fstab.

@keltek
Using UUID instead of label like /dev/sda* is a better way, so I guess nothing wrong with it.
FYI, I'm using systemd-boot as the bootloader, which is also the way ArchWiki recommended.

So I should install and set up systemd-boot for my bootloader? I don't remember ever explicitly setting up a bootloader so maybe that's my problem. Not sure how it fixes the issue of the weird behavior when volume is defined.

The wiki doesn't recommend using any specific bootloader.

Refind is a good bootloader, you don't really need to install another one.

initrd /initramfs-linux.imgMake sure that you configure Refind correctly. Your menuentry doesn't work since the kernel and initrd (loader and initrd lines) are on a different partition, not on the ESP.
You have /boot and the ESP as two seperate partitions, take that into account. It would be easier if you used the ESP as /boot.
Read this article to learn more.

@teateawhy to use ESP as my boot would I just add the kernel into a directory in the ESP and point to it from my menuentry?
Also, while doing some more experimenting I decided to try re-running refind-install from my mac. This has yielded an interesting result. Refind seems to have now auto-detected my Arch setup and has given me an option for it in the menu. I know this isn't my doing since currently my menuentry for arch is disabled. The problem now though is when I try to boot into this arch menu option given to me, it fails with the error
ERROR: device '' not found. Skipping fsck.
ERROR: Unable to find root device ''.Either way though I'm ultimately going to want my arch install to be booted from a custom menu entry anyway but if I can get it even just working for now that would be very helpful. I'll try moving my kernel to the esp though.

So while I doubt this was the source of all my troubles, through playing around enough I came across one glaring error. The PARTUUID I specified in my options "root=PARTUUID=XXXX" was missing one block of characters. Fixing that I now have a working system. Since it's working for me I'll call this resolved but it's an odd issue either way.
