macOS 12 Monterey on Unsupported Macs Thread

A question: Can/should I reverse a pixlas mod, or should I just unplug the Vega and let the cables lay in there disconnected? I purchased a modded 5,1 about a year ago, but am now having debilitating watchdog/windowserver crashes and have switched back to a different machine while I troubleshoot my Monterey system. I want to try it without the card and with a different one, to see if it is the issue. GPU is not important to me as I work in audio.

I wouldn't Worry about the pixlas. All it is, is just wiring, does not effect the heat. Just slap back in another card in it.
 
Hi all trying to install Monterey on an iMac 8,1 with SSD. Metal with oclp goes with no issues until the timer completes on the 2nd part of the install with the apple logo. The mac rboots into the installer again. I have tried pram rest 3 times and selecting the internal disc but it keeps going back to the installer.

Anyone any ideas? Thanks
 
Wait it out. It will reboot perhaps four times. DO NOT TOUCH ANYTHING.

You will know it's on the last boot, it shows a % bar.
 
I have an iMac8,1 that I test on OCLP. It's a challenge to reinstall, or update. It will often miss the OCLP EFI during a system intstall or update. I often will not allow it to restart on its own, but will shut down, then boot, specifically holding Option, to make sure that it first picks up the EFI boot partition, then goes on to boot from the actual installer, or the boot drive (depends on where it is in a system install. I am currently booting to Sequoia 15.3. I think it helped a lot when I upgraded the RAM to the max 6GB. I also use an external macOS installer when updating (less "troublesome" compared to letting the system update itself through System Settings/ General/ Software Update)

No matter how long I wait or how long I don’t touch it it keeps booting back into the installer and not from the internal HDD
 
I guess you mean that it boots into the Recovery system, with the menu giving you the choice to continue on with the installer.
What happens if you watch for that reboot, and hold the Option key, then choose the EFI partition, press return, then choose the installer (which should appear to already be selected (in bold), and press return again to go ahead with that choice (?)

Thanks mate it worked, did a pram reset as well
 
I would like to update - totally new method for me - to Safari 17.6 and macOS 12.7.6 using Terminal:

Last login: Fri Feb 14 14:18:33 on ttys000

❯ sw_vers
ProductName: macOS
ProductVersion: 12.7.5
BuildVersion: 21H1222

❯ sudo softwareupdate -l

Software Update Tool

Finding available software
Software Update found the following new or updated software:
* Label: Safari17.6MontereyAuto-17.6
Title: Safari, Version: 17.6, Size: 152370KiB, Recommended: YES,
* Label: macOS Monterey 12.7.6-21H1320
Title: macOS Monterey 12.7.6, Version: 12.7.6, Size: 11226114K, Recommended: YES, Action: restart,
* Label: macOS Sequoia 15.3.1-24D70
Title: macOS Sequoia 15.3.1, Version: 15.3.1, Size: 14867195K, Recommended: YES, Action: restart,

Are the two CLI commands below correct to be used on macOS with OCLP 2.2.0 installed?


"sudo softwareupdate -i Safari17.6MontereyAuto-17.6"

"sudo softwareupdate -i 'macOS Monterey 12.7.6-21H1320' -R'" <-- the use of 'label'

Any heads up much appreciated.

I am running OCLP Monterey on my Mac Pro 3,1. Bluetooth doesn't work and I am probably not getting an updated bluetooth card but I got a $5 Asus BT400 usb bluetooth dongle that was supposedly usable for this machine and am finding it doesn’t work. Wondering if there is some special way to get this dongle to work or if there is another known bluetooth dongle that will work? I'd like to get Bluetooth working again on this machine and then upgrade to the next OS up if possible.

Go to the Mac Pro section and use the search function to filter Mac Pro 3.1 only content. You should be able to find those threads with the Bluetooth upgrade options. There have been numerous options out there that you can use. Also search on YouTube for Mac Pro 3.1 Mod content. Also use Reddit on your Phone to find Mac Pro 3.1 discussions & Mod groups for further information. Also e-Bay has sometimes mod kits for that MP 3.1 of yours. Good hunting!
 
Okay so after a long time have decided I should upgrade my MacPro 3.1 from macOS Mojave to macOS Monteray..
Downloaded Open Core 2.4.0.
Managed to create the bootable installer.
Trying to boot to the installer was not a success, after about 5 minutes get black screen with white apple,
progress bar gets about a third of the way across, then stops and get a no entry sign with some text about apple
support.
On booting back to my Mojave install I am now finding that all USB no longer work.
How do I get this functionality back.

You have to make sure you are patient!

It's take long, and multiple re-boots.

AFTER about four reboots, you'll see a % progress bar.

BE PATIENT
 
Ahh patience resulted in getting Monteray up and running on my old slugger (MacPro 3.1).
I did know by installing Monteray on this MacPro that I would lose the functionality of all
8 CPU cores and only left with 4, fair enough, I thought I'd try Monteray out anyway and install.
Now this old Mac of mine runs other OS's on internal disks, such as El Capitan, Sierra and Mojave.
What I did not realise was that having installed OCLP and then Monteray that the older OS's would
not be able to run with the full 8 cores when booted up.
The question is, is there any way to get the Mac functioning with 8 cores when it is booted to the older OS's,
but when I boot to Monterey it will only use the 4 cores.

Any advice gratefully received.

I suggest to remove Opencore enirely, and reset Vram.

Would I do is keep my older Mac OS on a separate drive.

That way, when I needed to access older sessions, etc. I would just pop it on and work on that drive.

When I'm do I would remove my older Mac OS and pop in my newer Mac OS with OC installed.

Just do a deep NVRAM reset and you are good. You should see the cores come back.

Also a dual CPU trays are cheap nowadays. I wouldn't hesitate on upgrading the tray.

Did a NVRAM reset and still only 4 cores on this MacPro 3.1.
Removed drive with Monterey on.
Inserted, new SSD and installed Mojave, still only 4 cores.
