  • Unrecoverable Error: something something TeamViewer

    Posted by Jim Curtis on November 6, 2020 at 12:58 am

    This was an error message I got after rebooting after using TeamViewer to let a Tech Supporter at one of my plug-in developers trouble-shoot my computer. Needless to say, I nearly had a heart attack. I’m forced to use Catalina on my MacPro7,1 (10.15.7). I rebooted several times and could not get past this error screen, until I attached my boot disk clone, booted off of it, and then erased the boot disk, and restored my boot disk to its state three days prior, when I last cloned it.

    What was horrifying about this is that I initially suspected my internal boot SSD was borked. I’ve read those are not user replaceable. Had it been borked, I would have been many hours or days without the computer I use in my business until I could either get an Apple “genius” or an authorized service tech to fix it.

    Now, I would like to know for certain whether the boot SSD that ships with the new MacPros are indeed not user replaceable. Does anybody know?

    This apple support page suggests that the SSD modules are replaceable but it’s tricky business because of the T2 security chip.

    Install or replace SSD modules in your Mac Pro (2019)

    Thanks for that link, John. I suppose I need to be ready in case the worst happens.

    BTW, I’ve also read elsewhere that you can’t mount a new MacPro with an external drive. That’s not true. There are some “security” features one has to address, but if this wasn’t possible, I would have been in deep doo doo. I suggest other readers take precautions.

    I’ve had reinstall Catalina at least a dozen times since December, including after this scary error business. My computer wasn’t visible on my network, and reinstalling Catalina fixed that (again).

    Yes, there are some settings that disable booting from external media and you need to boot into recovery mode to change them.

    I don’t know what has gotten into Apple lately. They seem to want to make their computers harder and harder to use. I get security and all that, but being able to boot from external media is critical for not only recovering from crashes, but booting multiple versions of macOS. Since Apple has made them less and less backward compatible the need to run older versions increases.
