Plugged in HDMI Cable - Gave Power Issues and Consent Alert Sounds

John Gault Said:

"I think we're discussing different things. You have to boot Recovery mode to restore a Local Snapshot, so Safe Mode isn't a factor."

-------

This Stands as: "Working as intended".

Used Safe Mode to Create a New Administrator. Used the New Administrator to stop getting the "beep". Elsewise, I wouldn't have been able to log in.

1. Booted: into Safe Mode
2. Created: the New Administrator
3. Logged Out: of Safe Mode
4. Used: the New Administrator to boot into Recovery Mode (elsewise, I'd keep on getting the beep).
5. Restored: through Recovery Mode

Works fine for the last day.

Hope that explains this clearly.

"HDMI cables suffer from a lack anything resembling a cohesive standard. The cable may be inappropriate or defective, so try another one."

Thanks.

I let the Mac sit for a bit. Can't get into the login screen. Pressing the buttons, I keep getting the Glass "alert sound". So, maybe it isn't the HDMI cable.

"Maybe it isn't. You can't even get to the login screen now?"

-------

No. I get to the screen and all there is is the background - without pressing a key, or being able to use the Touch Bar, I cannot, therefore, proceed to the login screen. Tried Safe Mode - that works. I am wondering if a TMB Recovery, or if a reinstall (not reformat) would fix this?

John Gault Said:

"You can try a quick fix, which is to restore a Time Machine "local snapshot" which takes all of two or three minutes from start to finish. I'm concerned something about that HDMI cable may have caused some other problem to arise. It doesn't seem very likely though."

-------

Fixed (Maybe For Now):

Tried the "Local Snapshot". Somehow can't do it in Safe Mode (I'm not certain that not being able to do it in Safe Mode is normal). So, I created a new Administrator User, performed the "Local Snapshot" on that user - and it is fixed! I will be using it for a bit, and see how it keeps working out.

Note on HDMI Cable:

It's not Top-End (Monster brand), but rather a low-end cable that came with the projector I've been using with my Mac.

John Gault Said:

"Perhaps I'm just lucky but I literally use the cheapest HDMI cables I can find (Monoprice). This after a home theater installation company quoted me over $500 for cables alone. Forget that. Monster is a waste of money. Unless you're talking about Monster Beverage of course."

-------

I'll get back to this tomorrow (or if it pops up sooner). Let's wait and see how it all works out. Look forward for an update. But what about not being able to perform the "Local Snapshot" in Safe Mode: Is that normal?

I'll never know about Monster Beverage (for my own reasons) - but does it get you more enthused about using Macs.
