macOS 13 Ventura on Unsupported Macs Thread

Can’t upgrade from Monterey to Ventura: "The volume cannot be downgraded"

I have a multi volume setup on my internal SSD, original Monterey (afaik I always upgraded the OS from version to version), macOS Sonoma and macOS Ventura. EFI is 1.5n.

Now after heavy testing Ventura seems to be stable enough, therefore I’d like to upgrade to Ventura. But it seems I am out of luck and can’t follow this path anymore. No matter what I try (Recovery / OCLP bootable USB stick), I cannot install Ventura on the Monterey based Volume.

Any clues, how to circumvent a complete wipe of the Harddisk?

Thanks,
Joachim

You can install Delta updates but first revert root batches and restart then you will see the smaller delta update, once finished apply root patches again.

This does not work for every legacy Mac (e.g., I can't do this on my MBP6,2). If in doubt, don't revert root patches and allow OTA to download the full installer.

On a MacPro 5.1.

Before I give up and buy I new computer just so I can run QBD 2024 in the house office where I also use it for an extra backup I thought I would give Opencore one last try. OC 1.4.3 and 13.6.7 is working great on a clean install except for one big problem.

I can see everything on the wired network, access the internet and print. But I can not login into other computers and other computers can not log into the OC 1.4.3 and 13.6.7 box. Is OC the problem here? All the other computers in the office and shop can login to each other and the OC 1.4.3 and 13.6.7 box has the same settings.

I have searched and can not find anything relating specifically to this problem. What are find in regards to connecting to other computers?

@dymac My MBP6,2 running 13.6.7 is able to login to other computers (Windows and macOS) and is able to accept incoming connections from other computers. Do you have any firewalls configured on your Mac? Do you have a router that is blocking connections to your Mac?

EDIT: Prior to your Mac's upgrade to Ventura with OCLP (when it was running a previous, fully supported version of macOS without OCLP), was it able to communicate freely with your other office devices when connected to the same port on the same network?

EDIT2: One other thing... does your Mac have a single network connection or is it possible that it has two network connections (e.g., does your Mac have only Ethernet, or does it have active Wi-Fi and Ethernet)?

No firewall, Checked Router, not blocking connection. No problem connecting with previous version of macOS without OCLP. Ethernet only WiFi turned off.

Crazy thing I can log into two different Windows computers on the network. Tried connecting to the OC box from one of the windows computers and it will not accept the user name or password just like the other Macs.

I might just try to update it to Sonoma cause I figure I have nothing to lose at this point other than time. I have a 10.14 drive I can boot from for connecting for the backups. I just won't be able to run the software I need to.
 
@dymac If Wi-Fi is turned off, then your successful Sonoma test virtually eliminates OCLP as the culprit. Without disturbing your working Sonoma volume, are you able to add an APFS volume for a new clean install of Ventura? I'm not sure how, but maybe your first Ventura install was borked.
 
As many threads and posts as I came across about networking problems in Ventura made me think it was not OCLP. And since I could log into Windows machines I was convinced it was not OCLP. I really don't care about trying Ventura again.

How kewl, I have the oldest Mac here running the newest OS. Baring any problem I am going to get some serious life out of that old box now.

Stuck in login after OCLP upgrade to 1.4.3 in my Macbook Pro mid 2012. It was working so good with Sonoma... To make my day even worst, the CCC clone (babkup) won´t appears in boot menu. I am now typing in the same Macbook in a Linux Mint, but have no access to Mac partitions.

Any suggestions to solve this?a

Try safeboot with shift+enter on macOS partition and repatch in safe mode and may nvram reset. Good luck!

The version of OCLP 1.5.0 has now been released. However, I have discovered a bug.

When I try to install the root patches on macOS Ventura, the installation aborts with the message “Please ensure that you do not have any updates pending”

This refers to the update to macOS Sonoma which is pending. But users of macOS Ventura deliberately do not want to install this. It is therefore no longer possible to install the root patches on macOS Ventura because the update to Sonoma is pending.

Can other macOS Ventura users reproduce this bug?

I can't: 1.5.0/13.6.7/MBP10,2 works flawlessly.

Maybe an update is lurking on your mac.
Is there a folder here?:
/System/Library/AssetsV2/com_apple_MobileAsset_MacSoftwareUpdate/
Are this files present?
/System/Volumes/Update/Update.plist
/System/Volumes/Update/Preflight.plist

Please state your mac Model Identifier.

Yes I have this folder and the update.plist but not the preflight.plist. Should I delete them ? I have an iMac 14.2 Ventura 13.6.7

Important! Do not try to delete the "com_apple_MobileAsset_MacSoftwareUpdate" If there is a folder inside it you have a downloaded installer and you should delete it. The Preflight.plist as well.

Edit: So this is just a hunch. I do not know if it will help. But there is no harm done by deleting them. I have done it on several macs in the past.

Updated my 2016 base MacBook Pro to 13.5 without any problems.
Unfortunately I still have problems with streaming videos - HBO Max is literally not working 90% of the time and videos on YouTube and Disney+ stutter for few seconds (on Disney+ there are times the video stops but audio plays).
I'll probably downgrade to Catalina and update to Sonoma when it's available.

Anyone find a fix for HBO MAX stuttering on OCLP Ventura Safari? For me it happens about 15% of the time so mildly inconvenient but still annoying. Firefox takes up way too many resources compared to Safari, and Chrome is lol.

I'm wondering if maybe a certain version of OCLP solves this.
