I take advantage of a large number of exterior drives, most of them with multiple partition. Many of those drives are regularly re-partitioned and re-formatted for various makes use of.

Sometimes, after I join such a drive, I’m solely excited about one of many partitions, however the Mac’s OSX tries to mount all partitions it will possibly make sense of. I can, in fact, then unmount the partitions I don’t want mounted, however I’d quite positively select the partition(s) I would like mounted, and that the system leaves alone all different partitions. Aside from comfort, avoiding automount must also hold the unmounted file techniques unchanged (for instance hold the SHA fingerprint intact) and cut back the chance of knowledge loss by mistake.

I do know that I can disable automount for particular person UUIDs (see e.g. Methods to Disable USB Auto-mount). However since I join numerous exterior drives and their UUIDs change, I would favor to not name vifs after every media repartition and initialisation and ultimately muddle /and so on/fstab with plenty of noauto entries most of that are out of date after some time.

So I’m searching for a system choice to disable automount upon join alltogether as soon as and for all storage media and not using a have to individually disable. I’d then use finder or diskutil to mount simply the file system cases I select within the explicit state of affairs.

(Simply to say, the plain exception to my “no-automount” coverage ought to be the Mac’s startup disk, which is required for the system to operate.)
