I have 32 GB on this iMac 17,1, it could unofficially do 64 but i never needed that much. So I don't think I'll ever encounter running out of RAM for the remainder of macOS on intel.
Got a tip for us?

macOS 14 Sonoma on Unsupported Macs Thread

Still 8. Incredible that Apple can be so parsimonious, and memory so cheap...
for basic use, browsing the internet and the Office package, the 4GB is fine, but if you open a lot of tabs in Chrome (more than 6 for example), it may start to choke (I haven't seen this on any of the systems I've tested, all did very well: Catalina, Big Sur, Monterey, Ventura and Sonoma)
As mentioned, I have 32 GB of ram in this iMac 17,1. What keeps me with this Intel Mac vs just skipping OCLP and getting a new machine is, not really knowing how mature the ARM platform is when it comes to backward compatibility. There are people on this thread who have supported M series macs as well as their patched older macs. For what I understand though is, if I were to buy a new M Series Mac is: I would be good, going forward with macOS and keeping in the Apple ecosystem, or if I ran a VM, it would have to be ARM, and not x86, or X86_64. I know for backward compatibility, I have Mojave , or windows 10, or Linux for this iMac. I don't know what I'd have on a new Mac, and really I would like at least a 95% set it and forget it solution for current use and backward compatibility. One I wouldn't have to reboot too much for either.
Yes, perhaps it's a cMP thing. I tried SMC reset and NVRAM reset to no avail. We'll see what happens when OCLP 1.4.0 is released.
Odd one: BT on unmodified mid-2011 iMac, see this post on EIM

What have you done with an early Intel recently?
Well, here's an odd one. Bumped the 2011 iMac to Sonoma. As expected, Bluetooth is lost. Idly plugged in a generic CSR 4.0 dongle. Everything lit up perfectly. Here's the odd bit: I have an Orico USB3 4-port hub plugged into one of the usual IMac ports and taped onto the front edge. Plainly I...

@cmedina90 I also have the same model and for me the update went flawlessly (without using safe mode). I however never do the OTA update but download the installer. Only issue I still have, like with previous versions, are grafic glitches after lockscreen and password entry after putting display to sleep for a while manually with active corner (missing icons in upper right task bar, missing window shadows in light mode).
Update:
I found this nice and detailed tutorial (German) and enabled "Hibernation Work-around" in the settings to see if it makes my sleep mode wakeup problems disappear... https://macsofa.net/viewtopic.php?t=1325
Update 2:
The graphic glitches after sleep mode still occur
That might be caused by the fact that the activation of "Hibernation Work-around" is not saved/applied by my OCLP 1.3.0. When I close the app and open it again the checkbox is again unchecked.

The first is a poor translation which should actually read "use Safari, if download does not work with another browser". And regarding the beta versions, it's probably a matter of interpretation. That OCLP often works even with beta versions does not necessarily mean that they are officially supported. Just see the glitches with MacOS 14.4 now....
I just loooove the 'Unsupported Macs' thread. Come here to be corrected ever so gently, or not so gently occasionally, but almost always civil. Never a dull page.
An odd issue which I have searched for but not found anything similar reported.
2019 Intel iMac model 18.2, OCLP 1.3 worked perfectly in 14.3 all through the beta versions and now running the release version with no issues.
Updated to 14.4 beta 1, and even after running the post-install root patches, there is no network. And by no network, the mac denies that it has an Ethernet port entirely! No WiFi, the system preference pane for WiFi just doesn’t open. Even tried connecting a thunderbolt to Ethernet adapter, no dice. The switch port that the iMac is connected to lights up so the hardware is working, but, it appears, no drivers. Everything else seems to be fine BT, etc.
Tried the NVRAM and SMC reset, still no luck.
This was an update from 14.3 to 14.1b1 via Apple Updates. Next tried clean building a new OCLP installer with a new the downloaded 14.4b1 installation file. Wiped the iMac’s disk and clean installed. Exactly the same, no network at all!
Reverted the thing back to an install of 14.3, restored from a TM backup and all working again.
Just in case it was just some odd quirk, I have repeated this process again with exactly the same result. The only thing I haven’t tried is an install to 14.4b1, not restore my data, applications etc. from backup, set it up as if from new and see if the same thing happens. Before investing the time trying this and seeing if it works and then restoring applications and settings etc. gradually and trying to find out what makes it fall over; I thought I’d ask on here if anyone has encountered anything similar and or any suggestions.
I do appreciate that this is all beta software and oddness ‘should’ expected, plus 14.4 does seem a little problematic with OCLP 1.3, and if the suggestion is to just wait until a new beta or the next OCLP update then fine.
Many thanks in advance for any assistance.

Now have both my 2011s, iMac and MacBook Pro, running Sonoma with no apparent problems as yet.
Why are you even using OCLP with a 2019 iMac? you should be natively supported.
I tried and the screen still remains black. I also tried NVRAM and the screen is still black. thank you for your answer what to do video card or motherboard .Hold the on-off switch down for 10 seconds.
Don't play with beta without reading OCLP developers information.
It's announced that 14.4 beta doesn't work (yet) with OCLP.
Please be patient and don't expect support.
I still don't understand why OCLP is being used with a 2019 iMac at all. That should run Sonoma natively. As far as I remember, the specs says 2018 or later, so a 2019 / 2020 iMac should be supported directly by apple.
My bad, the model number is correct (18.2), typo, it’s a 2017 model iMac.
And I am fully aware that beta, is beta - odd stuff happens and breaks, (I’ve been tying out beta software on MacOS and iOS secondary devices for years), also I have read already that OLCP 1.3 is somewhat flakey to say the least with 14.4b1. As I said, if the advice is just wait until OCLP gets updated or Apple release the next beta, and try that then so be it.
I’m not really expecting ‘support’ as such, more reporting what I have found and could repeat and wondered if I hadn’t seen this reported anywhere also, if it something not yet discovered, something particular to my iMac or something which has been encountered before and can be fixed by something as simple as trashing a few plist files and rebooting - very unlikely but you never know!

It has been discussed here, and it's announced on OCLP discord.
14.4 breaks almost every OCLP patch
14.4 breaks almost every OCLP patch
OK, that makes more sense. I was just a bit confused as to why someone with a supported mac would even be here.
Anyway thanks for the correction

I tried to check mark "Hibernation Work-around" in OCLP settings (advanced) but it does not persist when closing the app. Does anybody know if this terminal command achieves the same: sudo pmset -a hibernatemode 0
There is a detailed page from Dortania regarding the sleep mode issues but I'm not experienced enough to understand it: https://dortania.github.io/OpenCore-Post-Install/universal/sleep.html#preparations
Any help is highly appreciated...

Everyone, without exception, has demonstrated that upgrading to 14.4b1, Breaks most everything in OCLP.
It has been stipulated, repeatedly, over the last few pages in this thread, and on the OCLP Discord,
to NOT upgrade to 14.4b1.
Stay on 14.3, until a new announcement is made.
What I don't understand is why 1.4.0 of open core was never officially released. It's supposed to fix the recovery partition issue from what I understand and everyone could benefit from that fix.
I would guess because they have pushed on past that feature and are working on the issues raised by 14.4b1. It would be nice to get a point release, say 1.3.1, containing the recovery fix though.
