Updated to Ventura using opencore legacy patcher. I need help!!

[AlyssaR]

So I have a 27" late 2015 iMac that was running the latest version of monterey. I needed to update to Ventura because my adobe lightroom, photoshop, and camera raw were no longer supported. I followed Mr. Macintosh YouTube video on how to install Ventura on an unsupported mac. I followed everything correctly. I partitioned a usb flash drive and put ventura and my old monterey on it just incase things went wrong. Everything went semi smoothly. I have everything up and going, but I can't connect my icloud. I'm logged into my apple ID. I can login to my icloud online. It says that I don't have permission and it says the same thing when i try to get into my Google drive folder. I also tried to restore my backups from time machine. I tried to add it to my Macintosh HD and it gives me this error an unexpected error has occurred error code -8062. Somehow some of my files got deleted off of my first time machine backup I did of my whole system before I started anything and a bunch of stuff got deleted from my Dropbox. I logged into Dropbox online and on my phone and everything but like 3 files are on there. I looked in the restore deleted stuff and nothing is there. I made sure everything was synced amd backed up. I'm not sure what I did wrong. Can anyone help? I also put my time machine backup on a external 2TB SSD. I've ran first aid in disk utility and everything came out good. And everything in opencore is good. I just can't get into some of my stuff. I also noticed i had lost some files in my time machine backup so I'm running diskDrill to hopefully get them back. I attended some of the pictures of the codes and problems I've been having.

So sorry to hear you're having troubles.

I've been using OCLP for about a year now. I've installed it twice on my 2015 MacBook Pro and two more times onto other people's machines. Out of all the 4 times, all 3 people were able to successfully login into their iCloud. I'm running Mac OS Sequoia now and it's all good.

I'm not a Mac OS expert, hopefully more experienced people will see your post and will comment. My immediate thought is something happened with the file system, or wrong file system was used, or you installed the Mac OS or the OCLP onto the wrong volume.

What I'd do if I were in your place:
1. Make sure you have everything backed up
2. Perform a clean install of Mac OS Sonoma via OCLP (below is how I do it):
A. When booting from the flash drive, open Disk Utility
B. Format all volumes on your SSD/HDD
C. Delete all the volumes on your SSD/HDD
D. Create a new APFS volume called "Macintosh HD"
E. Install the Mac OS onto this volume
3. Be very careful of where you're installing OCLP and Mac OS - that these are correct volumes.

I suggest also posting your question in Mac Basics, Help and Buying Advice. Happy to help more via comments here or direct messages.
