I can't begin to imagine they wouldn't work. You can use [tar] from the command line with a destination to the tape device just like any Unix. You can set flags and options to control block size and several issues dealing with tape backups.

Of note:
The default device for [tar] in Darwin, is /dev/sa0 which should be a tape drive. With the environmental variable of 'TAPE' you can select a different device.
You can specify an argument for the `--file=ARCHIVE-NAME' (`-f ARCHIVE-NAME') option whenever you use `tar'; this option determines the name of the archive file that `tar' will work on.
If you don't specify this argument, then `tar' will use a default, usually some physical tape drive attached to your machine. If there is no tape drive attached, or the default is not meaningful, then `tar' will print an error message. The error message might look roughly like one of the following:
tar: can't open /dev/rmt8 : No such device or address
tar: can't open /dev/rsmt0 : I/O error
Options
--atime-preserve Restore the access times on files which are writ-
ten to tape (note that this will change the
inode-change time!).
-L number
--tape-length number Change tapes after writing number * 1024 bytes.
-[0-7][lmh] Specify tape drive and density.
Environment
TAPE Changes gnutar's default tape drive (which is still
overridden by the -f flag).
Files
/dev/sa0 The default tape drive.

Lto Tape Drive Mac Os X

Lto 5 Tapes

The new StorageLoader, with its LTO-3 half-height drive, is the industry's first 1U, LTO-3 tape autoloader compatible and Apple certified with the Mac OS X platform. The new StorageLoader LTO-3 is now available through the Apple Store with a five-client license version of Dantz Retrospect Workgroup backup and recovery software, providing Apple. Using LTFS on Mac OS X for the Terminal interface illiterate.Changes the lto5 directory inside mnt folder on System drive to represent the LTO-5 tape drive -If you created the lto5 folder on your desktop you would use this command; ltfs /users/(current username)/desktop/lto5. When you look at the lto5 directory you will notice the lto5. SCSI Tape Encryption Manager - Manages encryption on LTO 4 and LTO 5 tape drives with hardware-based encryption. Program should work on any other SSP capable tape drives. Built specifically for Linux and AIX. Now supports key change auditing and key descriptors (uKAD). Check the Project News under the Develop section for more information. Dec 07, 2017 At the present time, there is no chance for a resolution with the ARECA or generic LSI SAS HBAs since they don't provide proper tape support under OS X. If you are using an mLogic mTape LTO-6 or LTO-7 Thunderbolt drive, be sure that it is a revision 2 drive (uses the HighPoint HBA internally instead of the ARECA) and that you get the latest firmware and drivers from mLogic for OS X.
