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!

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 .
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.
Your answer is in your question. Many people with old computers that work ok don't want to be forced to upgrade or can not afford it. It is a combo of the Apple bottom line and their own standards for acceptable snappy performance, the usual US vulture capitalism and market research. The apple silicon Macs are very nice and quiet and do hard processes with passive cooling that are unthinkable on Intel. Ah well. Not hard to figure out their switch from Intel when you have heard the singing of the fans from your old Macs for long enough
Ubuntu works too.

Good news. You don’t have to buy a new computer. Your 2018 mini will work just fine this year. And next year. And the next. In late 2027, you probably won’t get new security updates.
If you can save up $20/month between now and then, you’ll have enough for a great/new computer by late ‘27.
Thank you, @khronokernel, for this ride, and wish you the best in whatever you decide to do! Respect!
For me, the financial part exists, but in addition to that, for me it's also the direction Apple has taken as a company which has made me question if I want a new Mac. Let me explain:
As a Child, Apple was recommended to me as I have low vision, and back in the 80's 90's Apple was a very good platform for people with special needs, they were way ahead of the other options back then.
As I learned to use a computer and found more, and more I enjoyed using them for, I stayed with Apple computers.
Fast forward until today. I went through the 68K to PPC transition, and then PPC to Intel. The Intel migration was my favorite because it combined Apple and Intel, meaning owning an Intel Mac typically meant, you only needed one computer that could do, or run anything, unless you wanted to custom build a compute (of course.) Because of this, I've built up quite a few niche things I like to do with my Mac, or at least have the options available to me.
Switching to an Apple Silicon Mac will in fact, keep the Apple specific features, but then I'll lose the Intel related stuff like retro gaming, or legacy software that still works today, but may not translate well, or at all to the new platform, and there may, or may not be a suitable replacement, especially if the software isn't currently actively developed / maintained anymore. The other problem is finding an exact Apple Silicon replacement for this 27" iMac, it's the perfect size and form factor, in terms of physical size / space needed, and comfortable screen size visually, that's not too big, or too small.
So, that's why I used the analogy on the Sequoia thread of wanting a solution that's stable, current, and compatible, but includes Microsoft's ideology of backward compatible, Apple's cutting edge, and the flexibility of Linux.
The other thing is, I've found Linux to work well for running windows based games, where macOS can, but it doesn't work as well for certain titles. Someone mentioned a while back about the Apple Silicon Macs improving on this, but what about all the old 32-bit Intel based titles, that were either DOS, or older Windows games?
The main thing, holding me back from just switching to Linux, and calling it a day is mainly text message forwarding. This is more of an accessibility feature for me, as it's much easier to type on a touch screen, even with voice dictation options.
One thing people need to remember about me is, I prefer retro computing, but also like to be current enough for reasonable security, and compatibility, but I don't requite the latest, usually.

This T2 chip is not needed!!! Without the T2 chip, the system can work fine on older computers. What kind of system security are they talking about??? I still don't understand it. I bought a computer and this computer is mine, I can do anything with it, for example, change the graphics card and install a driver. That's my right. And don't let them touch me! Our people are poor. Apple is too rich. There are a lot of us people. Everyone can buy a cheap computer. APPLE has a lot of money. Apple also wants us to buy a new computer every year because of some unnecessary chip or block or something... I consider it violence on his part. People can't afford to buy expensive computers every year. I believe that Apple should stop introducing tricky prohibitions with some unnecessary chips... The OCLP programmer left us and went to apple. I think he did the wrong thing!An intel computer performs better than apple Silicon computers in all respects. That's my word! The graphics card should not be embedded inside the processor. The graphics card must be discrete. That's the only way! My word is that apple did the wrong thing.
I don't understand this animosity towards the OLCP developer. It's a strange reaction to say the least. These people give a lot of their time and energy to keep our unsupported Macs alive with the latest macOS releases. They don't HAVE to do it. We should all be grateful instead and thank them for their amazing efforts. Meanwhile OCLP isn't going anywhere, and while I'm looking forward to having Tahoe on my 2013 Mac Pro, at the end of the day there is no urgency, Sequoia runs flawlessly thanks to the team's outstanding work.
Heartfelt thank you for his work and I wish him nothing but the best for the future and his new endeavours.

There is also the option to show support by donating, which I will do again when the Tahoe support comes out, probably should do it anyway.
