[Release] macOS Tahoe 26.5

[Ludox]

[kgp]

Fast and painless sequential OTA update (3.97 GB) from macOS 26.4.1 (25E253) to macOS 26.5 (25F71). Same build as macOS 26.5 RC.

 

 

 

OCLP correctly selects Kernel Debug Kit 26.5 build 25F71 as the perfect match. 

 

 

Modern Audio, modern Wi-Fi and AWDL continue working flawlessly. 👍

My productive system continues working perfectly - including sleep/wake - like Swiss clockwork 🇨🇭🙂

If you're not seeing this update, it may be because you already have it.  It's just the 26.5 RC (which is still working perfectly with VoodooHDA.kext 3.3.4 for audio and itlwm for Intel Wi-Fi - no root patches, SIP csr-active-config = <01000000>).

 

 

For those who haven't been able to get external HDMI working on their HP Comet Lake laptops, here's a thread that may help you.  Happy hacking!

I have updated with no issue. Very easy. 
OC 1.0.7. MacPro7,1. Intel wifi + itlwm. 
I can’t say anymore because all is working as expected.

The installation was simple with no issue.
OCLP-Plus patched the new macOS 26.5 as usual in automatic mode.

Wi-Fi FENVI FV-HB1200, Clover Release-5172g.

Incremental update on the desktop. No operation made on the Acer laptop you know why.

Smooth update 🫠 As usual using Full Installer to avoid : stuck at login screen after entering user password.

Soooo.  I tried the update to the release version of Tahoe.  You may remember I dropped out of the beta program because of too many issues.  
Again the initial install went as expected until the final reboot was finished.  Then AGAIN I got the you have been updated to Tahoe screen which leads to the Apple account login which goes nowhere.  
I rebooted and went into recovery blew away my SSD and reinstalled.  This way I was able to restore my settings via Time Machine and I am back in with the updated OS.  But what a rigmarole.  I guess any further upgrades may result in the same method of updating.

i noted in the previous post that a full installer was used.  I may try that next time.

 

Cheers, Howard

I didn't see anything to click on at the Apple account screen.  You either sign in or not.  Both end up stalling and not moving ahead.  But really I shouldn't get these screens at all.  For all of the initial Tahoe betas things went fine and after the final boot I got to the desktop or was prompted for my login password.  Lately I've sometimes gotten to my desktop and can navigate fine but on reboot I get presented with the....you have been upgraded to Tahoe....blah blah.

 

If this happens again I will look for something at the left bottom.

Since I updated to version 26.5, my system has slowed down quite a bit, especially since while I'm working with Final Cut, my SSD is working harder than before. My timeline has slowed down and isn't as smooth as it used to be.

I was wondering if you've noticed this slowdown and how you fixed it.

Thanks.

 

I partially solved it by uninstalling FCPX and reinstalling it and it improved the speed a bit.

On hacks, I usually tend to use NVMe drives after that hardware was introduced. SSDs always gave me a bit of trouble because they were quite slow in comparison. An important tip I always use is to run GParted Live from a USB flash drive to format the SSD (if needed) using the slowest mode, since it cleans and adjusts the clusters.

If you don’t have Windows, you can use Fedora Media Writer to “burn” the USB flash drive.

The strange thing Max, I never had problems of this kind until version 26.4.1, I updated to 26.5 and the problem appeared, I'll see how it behaves in the next few days.

Sometimes it may be a separate issue related to missing “drivers” (kexts) in the beta version. It’s interesting how Apple has been abandoning “older” hardware (on purpose?) to avoid continuing support — at least in my opinion.  

 

It would also be interesting to check whether the USB kext you’re using happens to match the proper SMBIOS or not. I used to face this freezing issue both when using SSDs and even with NVMe drives.

 

 

This is my Mac Mini NVme speed.

If you're using a SATA SSD, do you have Kernel > Quirks > ThirdPartyDrives = True?

I'm sure that Ludox feels much better about his SATA SSD drive performance now.  

 

 

EDIT: @Ludox Confim that TRIM is enabled for your SATA SSD drive.  I don't have access to a SATA SSD in macOS at the moment, but you should be able to run this in terminal:

system_profiler SPSerialATADataType | grep -i "TRIM"

@Ludox Boot windows and run the manufacturer's utility for your SATA SSD to check its health and performance.

Hello everyone. I've been long-time member of this site, but I'm finally making a return after a long hiatus. It's been quite a while since I've put together a fully functional Hackintosh and the last one I got working is stuck on 10.13.6 High Sierra. I started my own YouTube channel not too long ago and I'm wanting to turn a PC that I recently built into a Hackintosh and have it running macOS 26 (Tahoe) or macOS 15 (Sequoia). My desire would be to document the process and I would appreciate whatever pointers any kind soul is willing to share w/ me in preparation for that process. I speak more a/b it in the following thread which I have linked below:

I have a problem; I've been using ITLWM and Heliport for a long time. When I try to use Ethernet, It  randomized restarts. I've tried many things but haven't found a solution. My motherboard is an Asus Tuf Gaming Z790 Wi-Fi D4. I'm attaching the EFI folder here. Does anyone know the solution? @MaLd0n

Hi @taranta babu Could you put details of your hardware in your signature, please. Actually, users who can help doesn't know what are your CPU, mobo, wireless, ethernet, graphic card, etc...
