Don't tell anyone, but the techniques used to extend the life of real Macs are hackintosh techniques.
@StefanAM I am old, but very unworthy of any bows. 🤣
Very OT - I modified OCLP 2.4.0 and was able to use it to complete the post-install patch application process in Tahoe Beta. No surprise, but UniversalBinaries.dmg needs to be updated for Tahoe, so my patched Tahoe would not boot. No harm done. I reverted post-install patches in Tahoe Recovery with
to restore a "working" Tahoe Beta volume which now boots and logs in completely without non-metal graphics acceleration.
Please let me apologize to those who would have preferred that I wait patiently for the release of the next OCLP before experimenting with Tahoe Beta. It's just not my nature to wait without trying. I couldn't help myself and quite honestly, I thoroughly enjoyed the adventure.

I have compiled myself, bypassing "Unsupported Host OS", "TeamID" and "No certificates" with my rudimentary skills and I had the same result.......
My good friend, how did you manage that? Your solution is simply brilliant.
Would this also work on my Late 2013 iMac (27-inch)?
Did you run these terminal commands under Sequoia or Tahoe?
When I run the above terminal command in Sequoia 15.5, I get an error message.
And how did you update the UniversalBinaries.dmg?
Thanks for the info and tips so that my Late 2013 iMac also works with Tahoe via USB and LAN.
Currently, it booted without graphics support and without Ethernet or USB.
USB is only possible with a keyboard and mouse connected to an OWC Thunderbolt Dock 2
connected to TB2 on the iMac. A USB stick doesn't work.
@Oxygen-X1 I only confirmed that we need to wait for the updated OCLP from the Devs. My experiment ended with non-working Tahoe that required me to revert the patches. The good thing is that Tahoe fully boots and I can log-in, but I have unaccelerated non-metal graphics and no wi-fi. I'll only need to apply the post-install patches when OCLP is updated. I don't want to get ahead of or speak for anyone, but what I observed gives me a lot of confidence that OCLP will support Tahoe.
While I was exploring OCLP to make the required changes for Tahoe, my admiration for the Devs increased significantly. OCLP is a technological marvel and a work of art.

Great effort! Thank you!
On the iMac 2011 27" computer, I decided to install from a clean install to a blank disk. The installation starts with a panic. I deleted the lilubetaall command. The installation went smoothly. I can't log in to the welcome system, it restarts. Added the lilubetaall command. Logged into the welcome system. The keyboard and mouse work without a patch. The welcome window freezes. He doesn't want to go any further. The system knows the WX7100 graphics card. There is metal. OpenCore 1.0.4.I upgraded to 1.0.5. The welcome window also freezes. The keyboard and mouse are working.
Here is the official word from Dortania on Tahoe support - No ETAs for Tahoe support. Don't ask, don't try installing it. If you try installing it, we won't help you. And this from the boss

Thank you so much for all your work that kept my machines running great!
Wish you the best in your new endeavors!

Starting next week, I'll be joining Apple's Bug Bounty team in Seattle.
Yeah, that says it all... with money, Apple can fix anything.
That's why he's letting the OCLP team down.
First, he was a big Apple opponent who, as he himself writes, didn't even work on the OCLP with Apple devices at first, and now he's working at Apple (for his former enemy).
This has absolute parallels to the time when a well-known iOS jailbreaker (I can't remember the name right now) also went to work for Apple.
It's good for Apple to eliminate unwanted competition like OCLP. After all, Apple has zero interest in supporting old Apple devices, even those that are more than 7 years old. Apple wants people to buy new APPLE devices!!!
Hopefully this defector won't hurt the rest of the OCLP team too much.

This assessment should reflect that the wrongfully described "defector", has been responsible for many old macs still having fun on new OS"s. We should be grateful. I know I am.
It's all true that he worked well at OCLP, but now he's switching to Apple and is therefore really a defector.
Shocker! It also turns out that I am running into more software that won't run on my OCLP'd machine because of it's old CPU. I guess the devs working on those projects are complicit in this madness!
It turns out that old stuff doesn't pay bills and things are getting more and more expensive. It takes a lot of money to support yourself and taking on extra work for no extra money just doesn't make a lot of sense to people.
Just keep in mind that life is not a zero sum game. When more people do well it helps even more people to do well. Let's celebrate the success of others and be grateful for the good they do. Building people up creates a virtuous cycle that we really need for society to flourish. 🖖
I'm sorry but as a contributor to the project, this just sounds hateful for no reason. Mykola is a great guy and very laid back, he's been always willing to help. Nobody in the team is feeling "let down".
It was his project in great part, which he created because he loved working with macOS and did it for free for everyone to use, while supporting it for 5+ years. He didn't have to do any of this, yet he did. It's perfectly fine for people to move on and seek for new endeavors after doing the same thing year after year. Especially with the knowledge he has of macOS, going to Apple seems pretty no-brainer and he has also helped Apple on the side already by reporting vulnerabilities.
Intel is gone next year anyway, so after Tahoe there isn't really much to be done after that other than keeping the project in maintenance mode for supporting Tahoe updates. As he said in the blog post, not much will change as there are other people in the team who are doing the research and development.
weird experience trying to install on my 4,1 flashed to 5,1.
With my vega 56 or either of my rx580s installed the system would hang while still loading in verbose mode every single time. Since I have my mac firmware flashed for GOP injection I threw my old gtx 1060 3gb in and it went straight through into the installer. I haven't had any issues with any of my amd gpu's before and had never tried an nvidia card in this system. Kind of confused as to why it worked but none of the amd cards would.

As I understand, the only T2 chip Macs able to run Tahoe natively are the MacPro 2019 and the MBP 2019, right? Being far from an expert or a developper, any ways we could « trick » our T2 Intel Macs to be spoofed as compatible Intel T2 Macs without OCLP obviously?

What better way to update OCLP than to work on the inside
. Seriously tho congrats when something that starts out as “just a few macs “ onto the giant OCLP has become I feel this could have a separate topic just to say Thanks .It is embarrassing to feel the need to defend the devs of such a great project that has been so useful to so many.
I read Mykolas statement and like many on this thread was there from the get go.
All Legacy Mac users with working brains are extremely grateful for the OCLP project. I know I am.
Probably the most useful and valuable open source project I have ever used and the utility from Big Sur to EOL Tahoe might approach or even surpass 10 years by the look of it so the utility is pretty substantial even if it ends with Tahoe in some way.
We all knew that this would end when Apple dropped Intel support and it is good to now have a date to think about what to do next and plan ahead. Heartfelt thanks to Mykola and the OCLP devs. Exceptional work. Ignore the noise.
I still cannot work out why Apple will NOT support earlier machines: after all, I, for one, running a 2018 Mac Mini do simply NOT have the money to buy something newer, and unlikely to in the next 2-3 years. By then I might be so effed-off with Apple I'll default to my "second love": Xubuntu, on one of several perfectly capable, far cheaper machines I have lying around the place winking at me. Now, were Apple to let me bung "Tahoe', "Vegas', and "Whatever-that-funny-area-in-America-where-the-aliens-land" I might feel more PRO investing in a newere Mac when I have the money rather than a nice wodd-turning lathes and/or a set of semi-decent golf clubs.
