Anyone else do the recent 10.15.4 update and have their machine completely bricked?
Mine will not turn on...not after resetting the SMB...not at all. Apple's update appears to have completely killed my macbook. It's now completely unresponsive.
I understand your Mac won't turn on. Please read If your Mac doesn't turn on - Apple Support.
That's all you can do. Of course there is no harm in repeating Reset the System Management Controller in what's likely to be an exercise in futility.
That brings you to the conclusion "If you still need help, please contact Apple Support."
Just contact Apple Support over the phone. They will set you up for a repair and you can mail it in for service.
There’s more to the conversation
Read all repliesBoot into Recovery (Command R) and from the dropdown menu: Utilities> Disk Utility> run the First Aid on your Macintosh HD (and the "Macintosh HD-Data" volume as well if Catalina) If errors are found and repaired, run again until no errors reported.

Hi, thanks for the suggestion. This, however, is impossible...because no key combination enables the computer to even begin to power up. It is a brick. Completely.
Hi and thanks for trying to help!
Booting...much less booting into recovery mode...is what doesn't happen. I have tried everything (resetting SMC)...all known key combinations.
Computer is connected to power...and nothing in either of the articles suggested here in this thread have helped to get the thing to even power up.
Thank you again for trying to help!

Thanks John.
One last question...is there any potential value in disconnecting the battery and connecting it again? Understanding that it's a bit annoying to get to...I'm trying to exhaust all options (as Apple stores are not open anywhere close to where I live).

Going down that road is likely to get this Discussion abruptly removed. Personally I doubt it, but... desperate times, desperate measures.
Just so you know what could happen, every once in a while someone comes to this site describing what happened when they tried to replace a battery on their own. Sparks, smoke, dead Mac, then they come here asking what now. So, proceed on the basis of that knowledge.
Got it. You've all been quite helpful. Somehow, I have the feeling that that Catalina patch is going to unearth a number of other bricked machines. Hopefully I'm the only one.
Nope. According to Apple you're the only one.

"I have the feeling that that Catalina patch is going to unearth a number of other bricked machines. Hopefully I'm the only one."
Oh no don't feel that way. Catalina actually has been a very successful upgrade. There are always small bugs but I had a 2018 MBP I upgraded to Catalina flawlessly. My 16" MBP runs Catalina without issue. Your issue is a rare occurrence. It's Apple's OS being installed on Apple's computers. "Bricking" generally is caused by corrupt files already installed on the user's computer that caused an install failure or it's a hardware problem. Other issues with failed installs come from temporary loss of wifi during install (if done through internet recovery) or temporary loss of power during the install, which could be a possibility of hardware failure. But OS's generally don't brick computers. Many thousands of people have upgraded to Catalina and there's no known reported issues of bricking.
Just to be clear, when you said "Catalina Patch", is this some unauthorized patch used to install Catalina or is this a genuine OS upgrade directly from Apple with NO hacks used to install it? Is your Mac a Catalina-supported model?
I've had Catalina installed and functioning well for quite some time now. The "supplemental update to10.15.4" that was released 2 days ago is what caused the dramatic fail.
It is, most certainly, a genuine OS update from apple...with no hacks used whatsoever.
Thank you for bringing this to the forum's attention. I didn't know of any supplemental update. I just installed it on my 16" MBP and everything went 100% smoothly. I just press the UPDATE button and left alone. Took 8-10 minutes to complete and I was back on the desktop. This is not a widespread issue.
I installed the newly released 10.15.4 Combo on all eligible Macs in our home on Wednesday night with no issues.
Thursday evening my wife's Air still showed the update in System Prefs and clicked to install it. She said the dialog box said it was normal for the screen to go black, but it didn't say it'd never come back!!!
Her less than 18 month old Air is now officially bricked. Unresponsive to all attempts to remind it of its mission on earth. A stellar machine until that fateful click.
It is funny how the "my Mac is unresponsive" support document says to listen for fans, drive noise, boot chime, other normal computer sounds- this Air never had any of those sounds! ::grin:: It needs some lights for battery charge level, MagSafe adapter light, something to let us know anything about what's going on with it.
Sad to find out we'd not gotten Apple Care. I was traveling a lot the several months after she got it and don't remember what happened, but we apparently each thought the other would have taken care of that. Curious to see how that all works out when we can eventually take it in when we can go to an actual Apple Store again.

The Caps Lock key LED is about all there is.
