    hi everybody

    i already filled a support request for the following, but i just wanted to share it here as it migth be an obstacle for others as well:

    ExtFS for OSX only condiders partition of the GPT type [0700 / EBD0A0A2-B9E5-4433-87C0-68B6B72699C7 / "Microsoft Basic Data"], while the linux partitions [8300 / 0FC63DAF-8483-4772-8E79-3D69D8477DE4 / "Linux native partition"] are ignored.

    best regards,
    martin.

    hi mephist

    thank you for your quick fix!

    i've installed the release from the link indicated above and can confirm that now i can see the linux partitions as well.

    i have not checked if the descovery rely on the shorthand (8300) or GUID (0FC63DAF-8483-4772-8E79-3D69D8477DE4) syntax, as i guess the will never differ.

    OFF-TOPIC: unfortunately i still have serious problems with ExtFS as my 691.3GiB-partition is showing up well but i can't even navigate through the files. i will open an different topic as soon as i have more info about the number of files i have.

    thank you and best regards,
    martin.
