Is it because it is connected with Firewire? In that case you could move the disk over to a USB enclosure.

macOS Tahoe 26 on Unsupported Macs Discussion

My expectations are low since the battery is old and I don't plan to replace it - I only maintain the laptop for fun (no serious use cases). I won't be testing anything beyond the ability to login and capture an "About This Mac" screenshot until OCLP post-install patches are available for Tahoe.
Also, my "patiently waiting" comments are truly well-intended. I don't want new visitors to this thread to think that my successful macOS updates imply that OCLP is available and supported for Tahoe. And since I don't expect new readers to start reading this thread from the beginning, I'll continue to post my 'patiently waiting' status with each new update until the wait is over.
And while you don't need me to say it, Devs - take as much time as you need. My 'patiently waiting' comments are not intended to mean anything else.
It is my understanding that Tahoe does not support mechanical HD's. Sequoia does. Also Tahoe does not support vintage bluetooth Keyboards like the Apple A1016, which in my opinion is the most substantial bluetooth keyboard Apple made. However, I think, support actually left with Monterey. Doesn't make sense.
Mechanical HDs work in Tahoe. "Fusion" drives (HDD+SSD combo) do not.
I have several "mechanical HD's" that works via USB on Tahoe.
Great news! Keeping my 2012 up to date is something I have been enjoying more than I thought I would
I even let someone borrow it last week to get their work accounts fixed while traveling.
Which one? 9,1 or 10,1? Both?Great news! Keeping my 2012 up to date is something I have been enjoying more than I thought I would
Sorry, it is a 9,1. Love it as a piece of "old tech" that is fully loaded (2.7 GHz, matte screen, updated BT/Wifi, blu-ray player, 4TB 860 Pro), still okay to use despite being blown away in performance from newer models. The only problem I noticed, had it connected to a 34 inch ultrawide 3440x1440, and while the MBP could drive the display, the fans were ALWAYS on. It works much better just as a laptop
That is my machine. Unfortunately this "very promising initial patch" announce was published in june, and nothing happened since.Sorry, it is a 9,1.

Tahoe 26.1 RC (Build 25B77) out.

Because the devs aren't going to release anything until there's a final release, unless you're in the actual test farm. And as with every release of the patcher, they're not going to release it piecemeal. When they're confident they have a comprehensive list of computers supported, that's comprised of all the models they realistically hope to support, that's when we'll see a patcher.
Easy update to Tahoe 26.1 RC via OTA. Still waiting patiently for OCLP Tahoe post-install patches.
With each release of the final version, like 26.0 or now the upcoming 26.1 after the first RC version, it will take longer and longer until an OCLP version for macOS 26 is released. As I suspected from the beginning, it won't happen until next year, when they are sure they have a comprehensive list of supported computers that includes all the models they realistically want to support.
We can wait, for Tahoe (it’s probably a little more important to optimise Sequoia support, for now)…

As has been mentioned elsewhere on this thread, the devs who have been doing the majority of the technical work on OCLP for the past couple of years are still active. There is no need to worry, support will be released when it is ready.
While we have faith in the Devs, hearing that is always reassuring.
"Easy update to Tahoe 26.1 RC via OTA."
Excuse my ignorance, but:
1. What is OTA?
2. How did you do that?

OTA: Over-the-air. A web-search like Google returns lots of explanations and examples.
Assuming you are familiar with OCLP:
- Generate OC EFI with OCLP 2.4.1. If your Mac is not yet supported by OCLP 2.4.1, wait for OCLP 3.0.0 and stop here.
- Manually update the OC EFI generated by OCLP 2.4.1 with Open Core 1.0.5
- Manually update Acidanthera kexts to latest release versions
- Modify USB port map as described in this thread for Tahoe compatibility
- Boot with your new OC EFI and install or upgrade to Tahoe
- You can't install Tahoe post-install patches at this time, so wait patiently for OCLP 3.0.0

and do it on a test volume you can delete if you don't wait for 3.0.0
Edit: 26.1 OTW/OTA
On the "deletable" test volume--no problems.

Smooth OTA (full installer) update from Tahoe 26.1 RC to Tahoe 26.1 Release. Prior to update, turned off Beta Updates in order to detect Release. Still patiently waiting for OCLP post-install patches.
Recently had a private exchange with one of the remaining devs. He mentioned that there is some good progress (especially cMP relevant) but until a first release of a (3.0.0 ?) OCLP for Tahoe still a lot of issues have to be solved.
For me that´s a good sign and also a reminder to be patient...
Progress has been shown earlier in this very thread too, me first by permission of Edu and later Edu themself.
There's a lot to be done like for example you can reach full acceleration as a proof of concept to show and this milestone was reached but it still doesn't end there, if many apps or UI elements are still glitching then it's not gonna be very usable even if you have a shiny translucency in your Dock. It's the minor details that take a lot of time.
