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.
I am on a MBP 15” Late 2013. Installed the new 13.3 beta and it wouldn’t boot. Now it does boot into safe mode with acceleration and graphics issues. Trying to install OCLP nightly build on the existing EFI, I get this error:

An error occurred:
0:188 execution error: Volume on disk0s1 failed to mount
If you think the volume is supported but damages, try the “readOnly” system
(1)

Would appreciate any clues as to why this may be happening and how to resolve the issue.

- Radeon R9 280X (metal 1)
- BRCM 94360 on internal USB 1.1 hub (BT) and Wifi (PCIe)
- USB 3.0 PCIe card
- Thunderbolt Titan Ridge

All systems go!

When you say, "BRCM 94360 on internal USB 1.1 hub (BT)," I presume this does not use the internal USB bus?

because you can’t install OCLP in safe mode….
Wipe the drive and reinstall 13.2.1 or wait and hope a patch becomes available are your options.

Temperature is not your problem, but I think you have to replace or reconnect that temperature sensor or your CPU will remain as slow as it currently runs.
You could try Intel Power Gadget in order to monitor your actual CPU clock speed - although I don't know whether that will still work in Ventura. In case that tool always shows the same low CPU frequency for all cores, you know that the missing temperature sensor might be the reason.

i installed Intel power gadget that doesn't work as a single app but only through iStat Menus... attached the results during a test with cinebench... the cores work at maximum... i fixed the fan control a bit using that of the optical drive, above all, for the Heatsink GPU (before it was always practically inactive) and while before this setting the Heatsink GPU also rose around 45°, now with this fan control it is around 34-37°

it is necessary to run this setting of the fans at a speed slightly higher than the minimum due to the GPU that consumes little more and therefore heats up a little faster than the Radeon HD 6770m 512 GB I had (35W) against the current 45W of the Quadro K1000m 2GB

BTW, as for OCLP 0.6.2, it has been stationary for two weeks, now (while previously there were continuous, almost daily updates):

Woo, I may have to drop back to Monterey. Ventura on my 2012 Mini with 8GB of memory and an internal SSD, is like slogging thru mud. Anyone else having this experience?

Does the same apply to Monterey? Metal apps won't work on it too?

That has been the case for awhile (not specifically new in Ventura), since Apple officially dropped OpenGL acceleration.
Some 3rd party well-written apps can detect and switch between OpenGL and metal API, but especially the formerly "marzipan" ported-from-iOS stuff (afaik news, maps, find my, stocks, weather) does not work with OpenGL any more and mostly shows blank window contents or even crashes.

Hello everyone!!
I installed Ventura in my mac mini 5.1 and all works EXCEPT the "Settings". When I open the "OS Settings" all is "black-blinded". I applied patch succesfullly 3 times or more and I've tried some different options and the result is the same. All working and fast EXCEPT os setting, so, I can't manage my system properly. :(. Thechipset is INTEL SANDY BRIDGE HD3000 (and with OpenCore 6.1, theorically is supported)

Everything works that I can tell. There is just a lag with everything else.

Then there is no need to force it. Catalina still seems like the best solution for such an old iMac. Thanks again.

Unfortunately you cannot see the current CPU clock that way, you can only see how busy it is using the current (probably reduced) frequency. During a CPU benchmark your CPU will always be 100% busy, no matter how fast it is currently clocked.
 
Hi all. I have a particular question with running Ventura on a 2015 iMac 27, iMac 17,1
I have successfully installed Ventura 13.2.1 on the aforementioned iMac using OCLP 0.6.1. MacOS Ventura, OCLP and all apps were "freshly" downloaded directly from the developers' websites and freshly installed. No other applications other than Chrome, Brave and Opera were installed.The installation was uneventful and everything is running well except for Google Chrome and its "derivative" browsers. (By derivative browsers I mean those that seem to have been derived from Chrome... specifically, I mean Brave and Opera. All three of these browsers are extremely slow to launch. When I launch either of these browsers, a white window opens up with no menu bar. The window remains white for pretty well exactly 50 seconds. After this prolonged wait, the browsers function and all is well. Other browsers (I have tried Firefox and Safari) run fine. My iMac is the 3.3GHz version running the Intel i5-6600 and the AMD R9 M395 GPU with 2GB VRAM. The computer is running 16GB of RAM (4x4GB). I have divided the 2.12GB Fusion Drive into its component drives (128GB Apple SSD and 2TB Hard Drive). I have tried installing the OS separately on the SSD and on the HD. Both installations result in the same lag time. It is interesting to note that I have installed the same OS with the same version of OCLP on a 2013 iMac 27 and the problem has not occurred there. Does anyone have any insights or solutions?

I am running OCLP 0.6.2n and Ventura 13.2.1 on a iMac15,1 late 2014, which is very similar to your setup.
The OS and especially the OCLP should only be installed to the SSD. On my iMac, ungoogled Chromium downloaded from https://softaro.net/ungoogled-chromium/ runs fine with no lag at the start up on the 128 Gb SSD.
I would recommend using AppCleaner to uninstall Chrome, just to remove the tracking stuff. As the ungooled version cannot access the web store to install extensions, you may have to install a sync version first, install ad blocker etc, and then install the ungooled version. Sync version, older, available here (top, 1st item):
chromium.woolyss.com

Download latest stable Chromium binaries (64-bit and 32-bit)

Download latest stable Chromium binaries for Windows, Mac, Linux, BSD and Android (64-bit and 32-bit)
chromium.woolyss.com chromium.woolyss.com
Does that version also have the lag?

Yup, I reinstalled the root patch. I will try it a 2nd time to see if that helps.

I reinstalled the root patch a second time and the Mini seems a little bit more responsive. Now when I close a window it doesn't take 2-3 seconds for the click to close command. Now it is almost instantaneous. It's not like the current M2 Mini but it is tolerable.

yes it is, even if istat menus specifically asked me for the Intel add-on to monitor frequency or some other cpu data, but I don't see the frequency

In order to "Roll back to 13.2.1", use CCC to make a data only copy of your internal SSD to an external SSD connected via USB 3.0 or even better yet Thunderbolt, and also make a 13.2.1 USB install memory stick. Boot up from the USB memory, wipe the internal SSD with the Disk Utility app and then install 13.2.1. At the end of that process you can use that CCC backup on the external SSD connected by USB 3, to migrate you data, and you will be "rolled". Depending on your hardware you may need a USB 2 hub to get a wired mouse and keyboard working. On my iMac 15,1 the wireless keyboard and one of several wireless mice usually work well enough until you can run the post install patches with OCLP 0.6.2n (it's rather fickle as to which mouse it likes that particular day). In my experience, CCC is much better than Time Machine for this.

I appreciate the help but this is not true.
If you only copy your user data it won't be the same as before, there is other data that affects your account which does not reside in your home user folder, for instance in /Library or even in /Applications you installed.


I can wait for the real fix, not going to reinstall, I never ever reinstalled my OS from the very first OS X 10.0b, so for over 2 decades, I migrated...as in copied (DD or CCC)... my disk from the old Mac to the new mac, yes, that worked for a long time.
