Kernel panic during Sequoia 15.4 installation on Apple M1 2021 MacBook Pro with Sonoma 14.7.5

Have tried upgrading w 400GB disk space, no apps running.

Make it through Sequoia download, preparing and installation, but always KERNEL PANIC on restart.

/Library/Logs/DiagnosticReports shows 5x panic-full... reports for 5x times I have tried to upgrade to Sequoia.

1st time all apps on Sonoma 14.7.5 up to date.

2nd time restarted 3x times to clear any updates/locked files and safe mode on last boot, then normal boot and install... failed

3rd time ... tried Recovery Mode, installed Sonoma on top of existing,

Weird, noticed updated for Safari update available from 17.6 to 18.4, so installed it... then tried Sequoia upgrade... failed.

4th time... entered Diagnostics Mode, submitted report to Apple Support... no hardware issues....upgraded Parallels v19 to v20.2.2 because their web site now shows "*" by v19 support and forums show restart issues and kernel panic ... better to be on v20 for tested/supported use... maybe ARM drivers causing issue... then installed Sequoia update... failed.

Not sure where the 5th was... used a new TEST user... all the same failures.... reported to Apple... and Support...

PANIC - latest

"panicString" : "panic(cpu 0 caller 0x0): t6000dart 0xfffffdf03b568d70 (dart-dispext0): Can't ignore lock validation @t6000dart.c:437\nDebugger message: panic\nMemory ID: 0x6\nOS release type: Not set yet\nOS version: Not set yet ...

Kernel Extensions in backtrace:

com.apple.driver.AppleT6000DART(1.0)

com.apple.driver.AppleARMPlatform(1.0.2)

com.apple.driver.IODARTFamily(1)

SEE ATTACHED TEXTLOG FILE.

Just noticed SHUTDOWN_STALL(s) and RESET COUNTER with these Panic Reports. SPINDUMP?

Looking at web/apple forums... this appears to be kernel issue w M1 processor and in past, seems to be resolved by coding fix by Apple.... som refer to FIRMWARE updates for?

Thoughts?/Fixes? I'm scheduled to see Apple tech at Apple Store... Thursday.

PS. I thought maybe install Sequoia v15.0/1 and see if install based and then upgrade... avoid major "leap" of if M1 problems brought into play w later Sequoia release (regression). But I was told Apple hasn't made Sequoia individual downloads available?! I just spent $100 for Parallels update to work with Sequoia...

I would suggest a DFU Firmware Revive or better yet a DFU Firmware Restore. Both of these will reset the secure enclave chip & system firmware. The latter will also reset the internal SSD & push a clean copy of macOS onto the internal SSD. Unfortunately this process requires access to another Mac currently running macOS 15.x Sequoia.

How to revive or restore Mac firmware - Apple Support

FYI, "dart" I believe is Device Address Resolution Table used to delineate hardware and memory on an M-series Mac (internal & external). I'm not certain on the exact name since I'm unable to locate the information with a quick search, but this is what I recall from investigating a year or so ago to assist another user.

If you are seeing this crash with a clean install with no external devices connected and without any third party apps & restore from backup, then you have a hardware issue most likely with the Logic Board.

Edit: Please keep us updated with the results and whatever happens with Apple.

It is unacceptable for technicians to give a solution where you need to reinstall completely and still do a wipe

I have the same issue. I have 15.3.2 but cannot upgrade to 15.4 without setting off a Kernal Panic. USB install failed and I do not have another mac to do a DFU. Not a good look

100% agree .. Apple needs to explain itself when their software damage our expensive Macs also.
