Haswell is intel, not AMD. Just discussed the issue with an OCLP developer who wrote that AMD GPUs are free of the intel Ivy Bridge and Haswell issues. Your iMac confirms that fact.
Roll on Beta 3 lol (just been released)

Roll on Beta 3 lol (just been released)
Ok, so after install of Sonoma 14.1.1 via OCLP 1.2.1 USB stick, on iMac 15,1 5k late 2104 4Ghz Quad-Core i7 AMD Radeon R9 M290X ... it boots into Sonoma, but WiFi is disabled (and I cannot enable it). I'm currently taking a time machine backup and have set up internet sharing through my laptop & hardwire ethernet (basically using my laptop as a wifi to ethernet).
Not sure if the lack of WiFi is due to some issue with the OCLP root patches or not, I'll try installing those once time machine is finished (which could take a very long time with ~1m files changed post Sonoma install. The last time around, I was on OCLP 1.2.0 and Sonoma booted but after root patches, would hang 50% through the boot process. Wish me luck this time around...
Of course, I knew that Haswell refers to the Intel CPU, look at my post above, i.e., "Haswell CPU".Haswell is intel, not AMD. Just discussed the issue with an OCLP developer who wrote that AMD GPUs are free of the intel Ivy Bridge and Haswell issues. Your iMac confirms that fact.
In regard to the other iMac 15,1 user with Wi-Fi issues, I have a POS router (optical fiber internet ONO) that is far too old and only has older/poor security for the Wi-Fi, but it does work. The router part of that ONO is OK, as is the internet speed. That iMac 15,1 is still quite usable, thanks to OCLP.
Sonoma 14.2 b3 installed on M2 MBA and iMac 15,1, (OCLP 1.2.1) no apparent issues so far.
There are significant differences between AMD and intel GPUs irrespective of the CPU. But you know that? 🤷♂️
@Ktwo I have been using Macs for more than 30 years, probably close to 40. I am now 77 years old and there is still a lot I don't know about computer science, especially programming, networking and command line language, but simple things like the fact that most Intel based systems have an integrated GPU and a dedicated or discrete GPU is something I have known for years, especially after struggling with an older 2011 MBP! That MBP had a Sandy Bridge CPU with an integrated HD3000 GPU and an older AMD discrete GPU (can't recall the model name/number off-hand). The term "Haswell" is only one of Intel's in-house reference terms and generally it indicates the CPU. Granted each successive version of the i series have had an associated integrated GPU, the term "Haswell" or "Koby Lake", for example, refers to the CPU and integrated GPU as one unit. Satisfied?
Sonoma 14.2 Beta 3 (23C5047e) upgrade from Beta 2 installed without any issues via OTA on MBP6,2 patched with OCLP 1.2.1 (Release). AMFI, Library Validation fully enabled. FeatureUnlock = Partial.
EDIT: Recovery mode boots without issues.

I don't really understand your comment "Hmmm?? Nice iMac, tho" What does that "Hmmm??" mean?Is this the same iMac from your Ventura post #7,535??
View attachment 2312142 Hmmm?? Nice iMac, tho.
I am not attached to that machine at all, so I don't take that as an insult, as it could be, just curious.
While that iMac does have its good points, it also has some serious issues. If you connect another monitor to it, it rapidly generates some serious graphic issues, display distortion that makes it barely usable. This is a well-known issue that has been discussed on the Apple forums and other places to no end. Replacing the graphics parts doesn't fix it either, as it will reappear. As long as you don't connect another monitor, it works fine. Still, it is almost 10 years old and that shows in various ways.
The update to Sonoma 14.2 b3, for example, took at least 4 times the time my M2 MBA took.
Login loop still present with 14.2 beta 3 on my iMac 13,2 with OCLP 1.2.1 release. WindowServer error 692.
Login loop still present in 14.2b3 as was in b2 with MBP 9,1 with OCLP 1.2.1 and 1.3n
I also experienced the login loop after installing 14.2 Developer Beta 3 (23C5047e) on MBPr 10,1 with OCLP 1.2.1.
How do I access the 14.2 b3 release? My iMac 15,1 OCLP 1.2.1 attempts are hanging 50% through the boot, though I'm not sure if the root patches installed correctly this time around because the root patcher did NOT restart the machine it just disappeared while running, and I had to manually reboot. This was after a very long time machine backup run. The machine spontaneously rebooted while simply scrolling in iMessage too.
So I guess I'm going to install 14.1.1 one more time and try the root patch one more time, unless I can find 14.2 b3 somewheree
I have been getting the login loop with 14.2, b2 and b3 so I have stayed with 14.1.1 which has been working with OCLP 1.2.1
Puzzled by the apparent lack of distinction between a CPU and GPU during the discussion. Didn't mean to challenge someone of experience and seniority like youself, sir. Live long and prosper. Hard stop....
Apology accepted, soft stop.Puzzled by the apparent lack of distinction between a CPU and GPU during the discussion. Didn't mean to challenge someone of experience and seniority like youself, sir. Live long and prosper. Hard stop....
That "apparent lack of distinction between a CPU and GPU" was entirely on your part alone. Look at my posts, and you will not find anywhere where I said "Haswell" was a GPU. I always referred to it as a CPU (granted all of the iCore series have integrated GPUs), but the terms "Haswell," "Sandy Bridge," etc, all refer to their respective Intel CPU line. In the future, please take care using language like "Hmm..." that can be taken several ways. Your posts and experience in this field are too valuable to waste through needless misinterpretations.
In general, Apple does not release RC versions as full installers. Even the Mr. Macintosh site has noted that fact several times. It seems like it is best to wait for a while in any case, so the OCLP developers can find the reasons for those Boot-loop issues and produce a fix. If anyone can do it, they will.
Ok so, I see "lots" of people saying iMac 15,1 OCLP 1.2.1 Sonoma 14.1.1 is working fine for them. It's not for me. It hangs about 50% through the boot. However, Sonoma 14.1.1 boots fine IF the root patches are not installed. I then just don't have wifi and desktop image and the system runs crappy ... dunno if there's something funky going on ... but it boots. My system is not a stock iMac 15,1 ... I replaced the fusion drive with a 4T NVMe SSD Could that be what's hanging whatever the root patches are putting into place? I guess the next thing I'm going to try is all of the above but with Sonoma 14.2 beta.
Is there any way for me to get the OCLP devs details as to what's hanging the boot? Does it leave logs that I can retrieve by booting from an installer or something?

I think the apple menu about on iMac 15,1 machhines states Haswell, so it's natural to quote that content.Apology accepted, soft stop.
Sounds like you could safe boot into your system using Shift (hold during bootprocess) + Enter after bringing up and selecting the bootvolume screen using Alt. Then unpatch the system and boot normally without patches.
14.2 b3 is available through SystemSettings/SoftwareUpdate once you are signed up for the developer beta programm.

I have an iMac 17,1 with Fusion Drive setup.
It's the small SSD Fusion Drive (24Gb) on NVME.
I have added a SATA SSD to replace the builtin HDD.
One supported Monterey (and also OCLP Ventura) this SSD appeared in the NVME section of the system properties:
Now, on Sonoma, it's not there (but I continue to use it in myself custom Fusion Drive of 2 SSD):
Apparently, there is no problem, but I wanted to be sure there is no regression in NVME settings ...

I take the freedom to recommend this new video from Jessie which might show the solution for most people with update problems...
