I have a 2013 MacBook Pro with both Mavericks and El Capitan installed (each on their own partition).

I now want to use Mavericks and High Sierra, each on their own partition.

Since High Sierra uses the APFS file system, will this prove to be a problem? Will it conflict with the HFS format use in Mavericks?

If there would be a conflict, how could I use both High Sierra and Mavericks on the one MacBook?

  • Is your internal drive a HDD or SSD? Are you using encryption? Could you edit your answer and include the output from diskutil list.

You do not have to use APFS to run High Sierra. Although, I believe if your internal drive is a SSD, then the High Sierra installer will try to convert the existing El Capitan partition and El Capitan Recovery partition to a APFS container partition.

Upgrading El Capitan to High Sierra should not effect Mavericks.

Note: Mojava (macOS 10.14) will be released on September 24, 2018

    There's at least one possible complication: since Mavericks doesn't support APFS, if the High Sierra partition does get converted, Mavericks won't be able to mount that volume or select it in the Startup Disk preferences. That means that to switch from Mavericks to High Sierra will require holding the Option key at startup.

  • @Gordon Davission: Another work around would be install rEFInd. You could select rEFInd from Mavericks and configure rEFInd to silently boot High Sierra.
