    Many thanks again, Don. I just tried your workaround exactly as you said--sorry, I know more about astronomy than about MacOS. It wouldn't accept that command in Terminal--here's a copy of my session (I hid the name of my HD below):

    (HD Name):~ sf$ sudo mount -uw /
    mount_apfs: volume could not be mounted: Operation not permitted
    mount: / failed with 77
    (HD Name):~ sf$

    Any advice?? Running Catalina 10.15.1.

    Thanks,
    stan in Brooklyn

    I haven't had this experience, but I'm guessing it's because System Integrity Protection (SIP) is enabled. To determine if it is enabled:

    1. Open Terminal and at the prompt type: csrutil status
    2. Press return and if it comes back with the status as: System Integrity Protection status: enabled. You'll need to disable it.

    Here's how...

    1. Boot to Recovery OS by restarting your machine and holding down the Command and R keys at startup.
    2. Launch Terminal from the Utilities menu.
    3. Enter the following command: csrutil disable
    4. Close Terminal and Restart the computer.

    Note that it can take a little while to boot into the recovery OS. I am assuming this is the problem, but having never seen that in my testing, it's the only potential difference between our computers that quickly comes to mind.

    Hope this is it.
    Don

    Yup. That was it. SIP. But it's late now and I'll disable it and try again in the morning. Will report back.

    Thanks so much, Don.

    Good. I just tested it by enabling SIP on my desktop computer and got the same error message you reported when attempting to make the system volume writable. I'll update the instructions in my previous post. You should be good to go once you disable SIP.

    Do not re-enable SIP once you have the drivers installed. The drivers are not signed and the system will not allow them to be functional with SIP enabled. This is a correction to a previous statement I made and have since deleted.

    Have a good night. - Don

    Hi Don,

    Just tested kStars with my STF-8300 after following your instructions. Worked like a charm! Thank you so much on behalf of all of us

    Thanks, Don, for posting the workaround, that's very helpful. One quick question - I'm a bit worried about disabling SIP since it is a security feature, but I'm not a computer person and don't really understand it's significance. Should I stop using my desktop for banking, etc., if it's disabled?
    Thanks, Kit

    One more thing...I just tried the workaround, but unfortunately I was still prevented from installing the SBIG driver installer due to it being "incompatible with this OS". I checked and confirmed that SIP was off, but it still wouldn't allow the installation.

    Hi Kit. If you still have questions about SIP, you can find answers here:
    https://support.apple.com/en-us/HT204899

    I have not had the message you received and have installed this workaround on a number of different Macs running Catalina. Since the latest SBIG drivers are 64 bit, there shouldn't be any reason for the message. Regardless, if you've followed the instructions given here exactly, let me know your macOS version number i.e.(10.15.x) and I'll see if I can repeat the error.

    Hi, Don, thanks for your reply. I was eventually able to install the drivers, the problem was operator error on this end. When typing in terminal to make the system volume writable, I didn't put in the / at the end. I thought it meant return. Anyway, I redid everything and then was able to install the drivers and reboot. Unfortunately The Sky still said the driver was missing. Am planning on using Parallels or boot camp at this point, so I've cleared the SIP configuration so that it's back on, and I think you mentioned that the system drive becomes readable only again when the computer reboots, right? The one thing I'm not sure about is when I originally tried to make the drive writable, but didn't end the command with /, but used a space instead. I got asked for my password after that, and when I entered it Terminal replied with a few lines that didn't make any sense to me. Unfortunately I didn't think to copy it. Is it possible that I did something seriously wrong? Thanks, Kit

    If you didn't include the '/', you would have been presented with a list of the current disks attached to the computer. This is because the '-u' flag was used, which signified that the status of attached disks should be changed. In short, nothing would have happened; so, you did nothing wrong. Once rebooted, all disks would have returned to their normal state anyway.
