^Older Macs tend to slow down for several minutes or even a few hours immediately after installing a new OS, precisely because of Spotlight indexing. Are you sure you let Spotlight finish its initial indexing task?
No, i’m not sure… but it doesn’t slow down it doesn’t responsabile at all.—
Anyway thanks for your suggestion, i’ll try to wait
 
That pic came from the instructions on the OCLP website. I was using 0.5.1 and that's what happened. I then downloaded 0.5.0 just to see if it would make a difference and I saw the same but yeah I downloaded 0.5.1
You might want to post screenshots of what you're seeing on your m/c rather than grabbing a graphic from the OCLP docs. It really helps us folks out here help you to diagnose the problem (and fix) accurately.

Running OCLP 0.5.1 on my 2012 Mini allowed me to proceed. I was then able to build my USB drive with OCLP and Ventura installed. However I now have another problem i’ve run into. After a couple of reboots installing Ventura I get a popup window that says: "An error occurred preparing the software update".

When I click OK the popup goes away and there’s another popup window that says updating but nothing happens. I thought it had to do with a lack of an internet connection so I connected the Mini via ethernet and I ran the install again and I get the same popup message.

Do you need a screenshot of that? Let me know.

Dis you install from Usb device to a clean partition or an upgrade of Monterey?

Please follow the guide closely.

If you are creating the USB installer on another mac, you must choose carefully the right model of your target mac. The boot EFI created is specific to that target mac model.

Edit - with that error message, re-start the installer again and again. It will get through eventually. See guide underlined text.

I have a 2012 and a 2018 mini. The mistake I did was try and build OCLP on the 2018 mini. That is why the Build OCLP message was grayed out.

I was able to successfully create OCLP 0.5.1 on my 2012 mini but I now get the popup message after Ventura reboots during the install process. It says there is a problem updating the software.

I created the OCLP 0.5.1 installer on my 2012 mini with a fresh install of Catalina. Once I got the message that the verification and installation of OCLP 0.5.1 with Ventura was successful I rebooted the Mini from the OCLP USB 16GB drive.

I then went into Disk Utility and erase the SSD partition that Catalina was on and used APFS format. I then proceeded to install Ventura on the 250GB SSD partition (APFS). The Ventura installation started and the second reboot I got the white Apple logo with black screen and progress bar. After about 30 mins into the process I get the popup message that it can’t update the software.

No, no please re read my updated comments. I was able to create the OCLP 0.5.1 USB flash drive using my 2012 mini with a fresh copy of Catalina. :)

The reason I had trouble in the beginning creating the installation drive was because I did that initially on my 2018 mini.

Rebuild the USB installer with verbose marked so you can see error messages during Ventura installation.
 
Am now on 13.1 Beta 2 & OCLP 0.5.1. Have to realize that the problems with the widgets crash have been gone since 13.1 beta 1. Weather can also be opened under 13.1 Beta 2 and does not crash.

I can't confirm the problems with betas that supposedly use TextEdit with CMD+C, CMD+V or the arrow keys.

Yesterday I updated my MacBookPro11,4 to Ventura 13.0.1, and once the installation finished it was all a matter of re-installing the post root patches in OCLP and I was all good!

Hello Everybody. I installed ventura 13.0 on my IMAC27 late 2015 (amd graphic) using OCLP 0.5.1. Perfectly working. After I installed the upgrade to ventura 13.0.1. Unfortunately, now I cannot run the root patches anymore. The error is the following: Kernel Debug Kit, could not connect to the apple download server. Thank you in advance for help.

You clearly have not read the OCLP guide.

All these times, stumbling like a drunk man asking for help here.

Read and re-read the guide... sigh.
But my friend I have asked questions and the response at times have been incorrect only because several commenters didn't read my updated comments. I always appreciate the help from the community but not reading things correctly can happen to all of us.

From your suggestion I take it the very first post in this thread. If so I did check the documentation page yesterday which is here and as I read thru it, it didn't seem to answer my question especially when I looked in the troubleshooting section. Now if that's not what you were referring to then please direct me to where I need to go.
 
Not sure if this graphical glitch has been reported before (couldn't pick up anything in a search) but certain websites on Safari (Youtube being one of them when trying to play a video) creates a weird broken screen type of effect (see screenshots). Apart from that, everything running smoothly on an iMac late 2012 13,1. Great job to all the developers involved. To think that just 6 months ago there was no hope of running Ventura on this machine.
Just an update. I hadn't updated to the very latest version of Catalina (EFI firmware was one version behind). After updating on Friday, the above major glitches haven't appeared again only very minor glitches like file icons not displaying properly. Also YouTube on Safari now works (but I did experience a playback error once or twice). Also no windowserver crashes (yet) but I did experience 3 prior to the update.
