hi folks, i am glad to announce that with the help of Sven and Chris, ceph-client homebrew for MacOS was updated with a recent master commit. this homebrew provides some essential client side tools and libraries which allow us to talk to a ceph cluster from MacOS machine, like: ceph ceph-conf ceph-fuse rados rbd in addition to the executables and libraries, the brew also packages the header files. so, if you are up to do some development with librados, librbd and libcephfs, you can also have the necessary bits from the brew. see https://github.com/mulbc/homebrew-ceph-client it comes with a pre-bottled brew for BigSur on amd64. the last release[0] of the brew was packaged 3 years ago with mimic-13.2.2 . please note, this is not official - do not expect frequent updates or support from Ceph. cheers, -- [0] https://ceph-users.ceph.narkive.com/bnyGalkH/ceph-client-libraries-for-osx -- Regards Kefu Chai
