macOS 13 Ventura on Unsupported Macs Thread

Status
The first post of this thread is a WikiPost and can be edited by anyone with the appropiate permissions. Your edits will be public.
A little advice needed, if possible, please.

I upgraded to Sonoma on my 2013 iMac, but now can't use my GoPro as a webcam due to Apple changing security settings. It's also been less stable in general than when I was using Ventura.

Therefore, I'd like to 'downgrade' to Ventura.

Has anyone done similar, and did you have to do a complete reinstallation to do so?

Just like to highlight that Ventura 13.6.5 (22G621) with iMac12,2 (K3100M) OCLP 1.2.1/1.3/1.4 is having trouble with Ethernet and WiFi (stock) via OTA update. The Ethernet works without the post-install patch. However both Ethernet and WiFi don't work after the post-install patch even though the System Info showed correct setting for WiFi (can see all the activated channels but can't detect any SSID).
I am yet to try the USB install option. Will keep you posted soon.
Also noticed the OCLP 1.3/1.4 "Create macOS Installer" has a bug whereby the prompt always show Ventura version 13.6.2 (instead of 13.6.4 / 13.6.5) and 22Gxxx shows the value of xxx-1 .

Has the NVRAM been reset? You may have to rejoin your network. In the OCLP CHANGELOG for v.1.4.0 released today🤷‍♂️

Yes, I did. This issue also occurred few days back when 13.6.5 was in RC with OCLP 1.2.1 / 1.3 / 1.4n. In the end, I had to wipe the disk and reinstall 13.6.4 with an OCLP 1.3.0 USB Installer. Today I tried again via OTA and the result is the same. Not sure if it’s the issue of Ventura 13.6.5 or the OCLP.

Likely neither. Read the OCLP v.1.4.0 release CHANGELOG. 🧐

Tried OCLP 1.4.0 USB Installer on top of the existing Ventura 13.6.5, the network issue is still there. I‘ve now wiped the disk and reinstall with the same installer. Will keep you posted shortly.
update: still no good. I’ve wiped the disk again and reinstalling 13.6.4 with 1.3.0 OCLP USB Installer.

And OCLP is updated to the release version?
 
update: The network for Ventura 13.6.4 with OCLP 1.3.0 worked again on my iMac12,2 (K3100M). I really don't know what I can make out of this. I am going to update OCLP to 1.4.0 to see if it breaks the network again.
update: OCLP 1.4.0 works the same as 1.3.0 for my iMac12.2 (K3100M) running Ventura 13.6.4.

The network issue for 13.6.5 is that both Ethernet & WiFi are de-activated (red dot) after applying the post-install patch which contains a legacy wifi patch (and a graphics patch). Interestingly, the Thunderbolt Bridge status changed from "not connected" to "connected" after the patch.

13.6.5 works fine on my iMac13,2 with OCLP 1.4.0, which does not need legacy wifi patch.

update_2: tried OCLP 1.4.1 which did not make any difference.

Hello, I'm new to OCLP and I have several questions please.

1. Has anyone updated to Ventura 13.6.5 yet and how did it work (and your Mac model)?
2. Did you install it natively via Software Update in Settings?
3. Did you update OCLP along with root patches before installing 13.6.5 and/or after?
4. In general, what is the best practice for Mac OS updates in the OCLP world? I've never done it.

Upgraded my MBP6,2 from Ventura 13.6.4 -> 13.6.5 via OTA with no issues. Booting with Open Core EFI generated with OCLP 1.4.0, post install patches applied with OCLP 0.6.8. There are no legacy Wi-Fi patches needed for Ventura.

Excuse me, so can I download the update, then I boot normally and have to do the "Post-Installation Root Patch"?
Coretto?
 
@vincenzo79 If you are installing macOS using OCLP for the first time, make sure you have a backup of your current "production" macOS volume and make sure you have a way to recover if your macOS upgrade fails.

When I test new versions of macOS with OCLP, I prefer to add an APFS volume and perform a clean macOS install in the new volume. This strategy preserves my original "production" volume while I experiment with the new macOS/OCLP. See my strategy here. I only perform OTA updates of existing macOS when I am certain that I have a backup and a way to recover if the update fails.

I completely agree with the backup plan that deeveedee recommends. You are using OCLP, which makes your Mac have a non-standard setup. That can sometimes fail more easily, and some of the updates WILL occasionally have a bad result, and you would need to back out of that update. Having a current full backup is (always) a good plan while you are using OpenCore. My main home Mac is a 2012 Mac mini, running Ventura 13.6.5, and have not had any recent problems with OCLP, and I usually will do an OTA update when that is offered. I have a less-used Mac, also running OCLP Ventura, which I use as a "victim" for OTA updates. When that other mini seems to update OK, I do the same update on my main Mac. So far, so good--I have only completely screwed up the system once on that mini. It try to avoid that, if I can...

When you install a system update on an OCLP Mac, the Apple update always removes the patches, so the first thing you do after the update, is to open the OCLP app, and reinstall those patches (the Post-Install Root Patch process). That patch reinstall will need a restart when complete. After that restart, then run the Build and Install OpenCore, which will redo the EFI partition for the most current OpenCore build. You will get to restart after that EFI build is installed. You will hold the Option key when you do this restart, so you can manually choose the EFI partition, press Enter to accept that, then click on your actual boot partition, and enter to accept THAT. After your system boots, be sure to check in your System Settings/General/Startup Disk -- to make sure that your boot system is selected in that Startup Disk window.

Let's see if I understood correctly.
I need to make a backup of everything and at this point I'm thinking of doing it with Timemachine. Any problems ?
For the steps for the updates, let's see if I understood correctly.
1. I start the Mac's Software Update system. This downloads the Mac update and then it should reboot. Correct ?
2. After it reboots I immediately open Open Core and run the "Post-Install Root Patch process" command. Right ?
3. If everything went well I shouldn't have any problems and the system should work properly. If this doesn't work, I have to install everything from scratch again. Correct ?
4. If the update doesn't work, can I start with the USB, delete the entire Mac partition and proceed with a clean installation of the operating system?
Thank you

Can you please advise.
What I've done just now on my MBP 2015:
1. No backups
2. Installed the Ventura 13.6.5 via Software Update in Settings
3. Done "Post-Install Root Patch" in OCLP
The system seems to work really well, even if I randomly restart, do I still need to "Build and Install OpenCore" now?
If yes, why? The only reason I see is to apply the setting not to show the boot loader when booting.

You only need to Build and Install OpenCore if changing versions of OCLP. A macOS upgrade does not touch the Open Core EFI, so if you don't change OCLP versions, then you only need to apply OCLP post-install patches when upgrading macOS.

I updated OpenCore, so do I have to install it again? I did not understand

I don't understand your question. Did you upgrade to a newer version of OCLP (which is different from Open Core)? If so, then you need to use your new version of OCLP to "Build and Install Open Core" and to apply post-install patches.

I would strongly advise you to read the Open Core Legacy Patcher manual, even if just to learn the basic terms and the basic methodology. See here.

Thanks for your warning! My iMac14,3 + Ventura 13.6.5 + OCLP 1.4.1 updated fine with no casualties. So I guess so long as the WiFi is not root-patched it is safe.

Hello, I have a late 2012 Mac mini (i5, HD4000) with 16GB of RAM and a 500GB SSD. I'm using Monterey and it's working very well, but I'm thinking about switching to Ventura. Do you know if it's slower than Monterey? I've read that Ventura is not very optimized for Intel computers, is that true?

On a 2014 Mini7,1 which supports the current Monterey, the performance difference running Ventura macOS 13.6.5 and OCLP v.1.4.1 is virtually identical. Have no fear. :cool: See #7990 above.

It does appear that OCLP 1.4.1 post-install patches break Legacy Wi-Fi for Monterey 12.7.4 and Ventura 13.6.5. Interesting, since Monterey and Ventura do not require Legacy Wi-Fi post-install patches. Yet another reason that I continue to apply post-install patches to Big Sur, Monterey and Ventura with OCLP 0.6.8.

EDIT: I'm not sure if the supposed "breakage" is in OCLP post-install patches or in macOS. Legacy Wi-Fi continues to work fine for me in both Monterey 12.7.4 and Ventura 13.6.5 with OCLP 0.6.8 post-install patches.

Certainly, you have seen this from Dortania -

"WARNING 3: Upgrading to 14.4 may break Auto Joining WiFi Networks​


To restore Auto-Join support, forget the network and re-add it.


WARNING 4: Do not install macOS 12.7.4 or 13.6.5 if you have a Mac with Legacy Wireless patches​


A recent change has broken the legacy wireless patches on macOS Monterey 12.7.4 and Ventura 13.6.5. A fix will arrive in the next version of OCLP. " 🤷‍♂️
