At this point we can pretty much guarantee that the operating system on the drive is dead. Repeated attempts by fsck all failing points to that conclusion. If you don't want the data then I'd attempt a reformat and re-install of the OS. If you do want the data then I'd see if it could start up in Thunderbolt mode and attach it to another Mac and use "...

I've seen this issue quite a few times before. For me, I booted into Single Boot Mode by holding Cmd + S on startup and typing fsck -fy. Let that process run and keep repeating it over and over until it says the volume is ok.

There may have been a time when Google Chrome was compliant with AppleScript commands e.g. run or launch, which would keep it in the background, as it does with e.g. Safari and other applications. Or compliant with with the shell open command using either the -g or -j options along with the -a option. In testing under macOS Catalina I could not get Google ...

Yes it does. If you set System Preference > Notifications > Calendar to Allow Notifications you should get a notification if you set the alert style to Banners or Alerts even if the app has been quit:

is there any official or reliable source that says this? (e.g. official documentation) Not explictly, but one can imply it from support document called If you don’t receive calendar alerts on Mac. There is is list of possible causes of not receiving alerts and none of them is 'because Calendar app is not running'.

-128 is a catch-all shutdown cause in SMC. It’s unfortunately not specific enough to suggest a particular line of investigation. From experience, a couple of things to look for would be: Poor battery health can cause voltage sag under high workload and leads to a brownout. Given that you’ve mentioned in chat that this happens under AC power, this is ...

Your filesystem is corrupted. That may not be the ultimate root cause of all this, but you won’t get any further in your debugging until you can repair your drive. Only then can we determine if there is a deeper issue that caused the corruption in the first place (e.g., a hardware failure in your DRAM). Since fsck has failed but you’re booting off an HFS ...

After almost 8 years of wondering why Mac computers (e.g. 2013 and 2020 Macbook Pro for my part) were overheating so much (reaching 100°C on both models when fully stressed) with Windows (installed with or without bootcamp), I finally discovered why thanks to your hint @Techno: My guess is that Mac motherboards do not handle the turbo boost mode of modern ...

Regarding @jwalker's answer above, the GitHub project has 0 commits since 2018, and Kernsafe's product has not seen an update since 11/2019. So both can effectively be considered abandonware at this point. Neither are working on Big Sur. Is there any way in 2021 and with macOS 11 to use network based block storage? I have some specific apps that require a &...
