@litemint09 If you want to contribute and help others, it would be a good idea for you to post your latest "working" EFI in the other thread.  Nice work!

 

EDIT: Just to be sure I wasn't misleading you, I re-tested sleep/wake on an HP EliteDesk 800 G4 Mini with my EFI posted here.  Through multiple sleep / wake cycles with Tahoe 26.6 Beta 1 there are no issues.  As I said before, I've never seen sleep / wake working properly on the HP EliteDesk 800 G3 Mini (Kaby Lake Desktop), so if you have it working on the 400 G3 ProDesk and it is Kaby Lake, you might be the first.  Sleep works on Kaby Lake laptops, so that might offer a clue.

Alright cool, thanks for the info, i gone into installing 26.6 and 26.5.1 both of them broke the sleep wake, i switch back to 26.5 alone and the sleep wake functions again. Seems going above that version, it totally broke the sleep wakes.

I was running very low on free disk space for macOS (< 5GB), so I swapped my hackbook's 500GB NVMe SSD for a 1TB WD Black SN770 (my laptop won't benefit from anything faster).  I knew that the increased space would lower swap activity, but I didn't appreciate just how much better the performance would be.  Tahoe 26.5.1 and 26.6 are both even better with the added space.  My disk partitioning is as follows:

  • 350GB Windows 11
  • 400GB Ubuntu Linux
  • 250GB macOS (multiple APFS volumes)

I'm multi-booting with Grub on the single NVMe SSD using a methodology similar to this.  With grub, I'm using OC only to boot macOS - not Windows or Linux.

 

EDIT: I added a thermal pad to the NVMe SSD that lets the SSD use the laptop's aluminum case as a heat sink.  NVMe SSD temp dropped from 38 to 32 degrees C.

Fast, and painless sequential OTA update (3.7 GB) from macOS 26.6 beta 1 to macOS 26.6 beta 2 (25G5043d).

So far, Apple has not released a Kernel Debug Kit for macOS 26.6 beta 2 (25G5043d).

 

Unfortunately, Apple’s inconsistent KDK naming scheme causes OCLP to currently select Kernel Debug Kit 26.5.4 build 25F5068a from macOS 26.5 beta 4 as the closest match for macOS 26.6 beta 2 instead of Kernel Debug Kit 26.5.1 build 25F80 from the final macOS 26.5.1 release.

 

However, my BCM943602CDP continues to perform amazingly with OCLP. Modern Audio, modern Wi-Fi, AirDrop, AirPlay, Screen Mirroring, Personal Hotspot, Continuity Camera and sleep/wake are all working flawlessly under macOS 26.6 beta 2.

Customised Icons and the Tahoe Drive Icons Pack continue working flawlessly, too.

Same boot system on laptop since more than year. On desktop I use Refind instead grub.

For those who are not seeing the "Beta Updates" option in "System Settings > General > Software Update" -OR- the only "Beta Updates" option is "Off," I have posted a fix here that may work for you.

 

-----------------------------------------------------------------

 

The incremental update from macOS Tahoe 26.6 Beta 1 -> Beta 2 proceeded without issues.

Spoiler

My system configuration is as follows:

  • Open Core 1.0.7
  • Audio: VoodooHDA.kext 4.0
  • SIP: csr-active-config = <01000000>
  • No Wi-Fi / no root patches

 

This hack had a clean installation of macOS Tahoe 26.6 Beta 1 (installed from USB installer, not an update).  Beta Updates were not available on this hack, despite running a Beta version of macOS Tahoe 26.6!  I used the fix documented here to enroll my hack in Apple's Beta Update program and then the Beta update went smoothly.
