Setting up cvmfs on MacOS.

[terjekv]

1. mkdir -p /Users/Shared/cvmfs/{cvmfs-config,pilot}.eessi-hpc.org
2. Install https://github.com/osxfuse/osxfuse/releases/download/osxfuse-3.11.2/osxfuse-3.11.2.dmg. Nothing newer.
3. curl -o ~/Downloads/cvmfs-2.7.5.pkg https://ecsft.cern.ch/dist/cvmfs/cvmfs-2.7.5/cvmfs-2.7.5.pkg ; installer -pkg ~/Downloads/cvmfs-2.7.5.pkg -target /

Note, installing the CVMFS package creates /cvmfs as a symlink to /Users/Shared/cvmfs by utilising /etc/synthetic.conf. If you want to have a MacOS build node and don't want to install CVMFS, you can do this yourself: https://derflounder.wordpress.com/2020/01/18/creating-root-level-directories-and-symbolic-links-on-macos-catalina/

But, please note that after editing /etc/synthetic.conf you have to restart for the changes to take effect, so...

4. Reboot
5. curl -o ~/Downloads/config-eessi-0.2.3.pkg https://github.com/EESSI/filesystem-layer/releases/download/v0.2.3/cvmfs-config-eessi-0.2.3.pkg ; installer -pkg ~/Downloads/cvmfs-config-eessi-0.2.3.pkg -target /
6. sudo mount -t cvmfs cvmfs-config.eessi-hpc.org /Users/Shared/cvmfs/cvmfs-config.eessi-hpc.org
7. sudo mount -t cvmfs pilot.eessi-hpc.org /Users/Shared/cvmfs/pilot.eessi-hpc.org

Note that one has to enable kernel extensions on Big Sur (11.0/10.16) for MacFuse to work. This requires a boot to recovery mode. This normally means booting with Command-R, but on M1s, you do shutdown and then hold the power button during boot until you get a message about Loading system options. See https://support.apple.com/guide/mac-help/change-startup-disk-security-settings-a-mac-mchl768f7291/mac for more information.

Updated for Big Sur. Also works on Macs with Apple Silicon, and should also work on older Macs, except the effort to enable system extensions varies a bit.

6. Reboot again so /cvmfs is created.
