Because it's the last macOS supported version for rMBP10,1 which lives on an external SSD. Actually it's the old 512 GB OEM drive in an OWC Envoy enclosure that I bought when I installed the OWC 1 TB drive.
Got a tip for us?

macOS 15 Sequoia on Unsupported Macs Thread

Consider following approach:
Edit: added some information, and work flow clarifications.
Install Catalina, download latest Sequoia installer onto Catalina -> install latest OCLP 1.6n ->create a new *Volume* (not partition) with disk utility and name said volume whatever you wish, e.g., Sequoia ->open downloaded installer package and launch it. It will place Apple installer application in Catalina's application folder. -> Launch the Apple installer located in Application folder. It will go through standard installation process and you should be able to install the Sequoia without problems. I was able to install Sequoia on iMac 13,2 when USB thumb Drive installation caused "... this mac is not compatible ..."; method worked for me on several occasions with different iteration sof Mac OS X Sequoia installed on internal fusion HDD and external USB.
Hope this may help.

That is very interesting to hear. I think maybe @houser got it working without problems on the same SSD, separate partition, because it would naturally share the same EFI, and both are recent versions. Maybe, but I really don't know.
Thanks everybody, great feedback. Now I've got Catalina back on the main drive I've got a few options to consider.
Just downloaded the latest nightly OCLP dated today. It's been relabeled "version 2.0.0 (Nightly)". Sequoia beta is appearing for downloading, and Sonoma 14.7 is not.
I updated 13.2/3802 OTA to 15.0, when the patcher starts it downloads "metal lib" before patching begins. I am now in the trees again.
The changelog has many interesting updates and now says 2.0.0. Thanks again to the Devs for early 3802 support.

Downloaded it too and metal support for 3802 is now in the main nightly.
Patched a rMBP 10,1 and it works for Sonoma as well as Sequoia b8 and updates for Sonoma and Sequoia appear as they should, including 14.7.
It is still a little hard to believe that we have been lucky to see this degree of legacy support for our old Macs.
Sincere thanks as always to the fabulous Devs!

With oclp 2.00ns Additionally Continuity Camera now works on my MBA 7,2 and b8. Thanx to the developers for their hard work.
Latest Nightly is 2.0.0 - adding a few more. Great work of the Developers.
But seems no chance for my 2009 iMac as he is 21.5" - non Metal GPU 🥲 (NVIDIA GeForce 9400 .. no easy replacement in sight)

confirmed on my MacBook Pro 10,2
The CHANGELOG for OCLP 2.0.0 is very expanded from previous nightlies:
https://github.com/dortania/OpenCore-Legacy-Patcher/blob/main/CHANGELOG.md
https://github.com/dortania/OpenCore-Legacy-Patcher/blob/main/CHANGELOG.md
I am able to play free episodes on AppleTV+, Youtube. With Netflix, I get error S7006.
After removing all data and log in again, it still does not play. I can play it on Firefox...
The Widgets created on Sonoma were blank when I updated to Sequoia. They remain blank after a couple of reboots, therefore I removed them booting in SafeMode.

rMBP10,1 2012 updated from Catalina to Sequoia 15.0 b8 + OCLP 2.0.0 nightly successfully.
Many auto reboots, took a while. Had one glitch regarding unable to find install-to drive which was a tad concerning. Only option presented was to start in target disk mode, no thanks!
So I did a forced power-off and restarted. Install process continued without further errors.
Looking very good at this point.

Random all widgets working fine that I left on from Sonoma with no issues but I can’t play anything unless it’s in Firefox, chrome, but photos, messages home secure video play without any graphical errors I was reading a discussion on the green screen where alot of people got green screen glitches from Big Sur beta 3 onwards and think mines related to that tried two MacBook Pros 2014 both experience same error but both ok with widgets but again they are the same specs maybe I was lucky I didn’t experience these errors in Big Sur.

Glad to hear it fellow 10,1 user
So far also less fans compared to Sonoma, but early days and don't want to jinx it
But agree, looking good...

I can create widgets and play ATV+ DRM content on both devices: MM7,1 and MBA 7,2 without any problem or did I missunderstand something?

I'm having issues with my Haswell machines, including the MM7,1. The MacBookAir7,2 is my wife's and I don't dare touch it until the developers bless us with the OCLP 2.0.0 release. 😂
What kind of issue do you have with your MM7,1? I canˋt realize any difference to Sonoma 14,6,1 with Sequoia b8.
Update: Continuity camera is working again with the 2.0.0 nightly build.
Not sure if iPhone Mirroring could be made to work on Intel Macs.
I know it is needed now, and according to what I have read, the T2 chip (and the moving target it is, T3, T4 etc) will probably never be emulated in a useful way on Intel. !t's "too complex and too performant." to quote a good post on Reddit. But if anybody could do it, I would not bet against the OCLP devs
The Apple ARM chips are currently the best there is, and when Apple closes the door on anything but their own silicon, the hackintosh and OCLP crowds will have to think again. I am sure Dortania will have some interesting thoughts on this at some point.
Regardless, we will probably need to be ready to buy a new Mac or transition to Linux on our old Intel Macs in 5 years
if we want security updates. Which considering it all, is not bad going for Macs that will be close to 20 years at the time. Unless someone comes up with a way for security and webkit updates etc. for the last Intel version of MacOS which maybe appears more likely than T2 support. ... and to close the loop probably not likely either.

Fully agree… in the meantime I am happy to run my 2009 iMac 10,1 21.5“ on Sonoma and my MacBook Pro 10,2 on Sequoia (no T2).I know it is needed now, and according to what I have read, the T2 chip (and the moving target it is, T3, T4 etc) will probably never be emulated in a useful way on Intel. !t's "too complex and too performant." to quote a good post on Reddit.

Thinking the iMac is already getting pretty old that’s not too bad 😇
Very thankful what the patcher team was/is/will be able to do
OTA Updated 12" MacBook 9,1 (not Air or MBP) from 14.7 to Sequoia 15.0 (24A5331b). Preinstalled 2.0.0.0n to EFI before starting. Final stage required NVRAM reset (space bar at OCLP start) followed by reboot and then Safe boot (Shift key) to get to desktop andf run root patch to correct display resolution and enable Wi-Fi. Seems to be OK but not tested all functions. Good job devs.
