macOS 12 Monterey on Unsupported Macs Thread

[sinbad21]

I just successfully installed macOS 12.5.1 (Build 21G83) DIRECTLY from System Preferences.
Upon reboot, the Opencore Legacy Patcher 0.4.10 warning appeared which suggested that I install the "Post Install Patch" and in the end it seems to me that the System is working much better than before.
Attention please
I am also creating a USB stick with the macOS 12.5.1 installer, just downloaded using "gibMacOS" and it is evident, from my second screenshot attached, that Apple has released a new installation file of the same Build 21G83, after a few hours from the first file. The new 21G83 file was released at 21:23:50
I point it out for those of you who in the meantime had used the file at 17:22:45 to create USB Key.
But don't ask me what changes between the two files, because I don't know...

Now there is a 12.5.1 added 2022-08-24. What does that mean ?

I’ve seen it asked a few times but no full answer on if it’s possible and if so, how to make it happen. I’m also trying to RAID0 my 2011 iMac with two 1TB SSD’s while using OCLP on Monterey.

I’ve been using OCLP for several months on one single SSD and have been very happy. On an everlasting effort to keep my ancient mac running as fast as possible, I dropped in a second identical SSD in place of my 2.5TB spinning disk (extra storage) and planned to configure them as a striped boot drive. Got all the hardware setup last night and went to install a fresh copy of OCLP only to get shutdown after selecting my array. “You may not install to this volume because it is part of an AppleRAID”.

I could have sworn I’ve even seen benchmarks of people showing blackmagic screenshots of systems in this configuration running well and almost double the throughput.

Sorry if the answer is deep in this thread and I missed it though I did search but didn’t find a conclusive post and/or a how-to.

I did some research almost a year ago, with the conclusion that, out of AppleRAID, APFS and boot, pick at most 2, but not all 3. https://forums.macrumors.com/threads/nvme-sata-raid0-late-2013-mid-2015.2318970/

So yesterday I was trying to upgrade my mid-2010 iMac to Monterey and attempted this again by copying a fresh, working OCLP Monterey install to RAID0 using CCC6. CCC6 now has the Legacy Bootable Copy Assistant because it is no longer able to make bootable clones without going through Apple's APFS replicator (https://bombich.com/kb/ccc6/cloning-macos-system-volumes-apple-software-restore), and sure enough the OS rejected AppleRAID as the destination.

What I didn't try was to disable SIP and get Catalina running on AppleRAID first and then try to upgrade that to Monterey. That however will be very unlikely to succeed unless Apple "forgets" to check if the boot drive is AppleRAID.

So before we can even test if it works at all we have to get AppleRAID to boot, but that seems pretty tight all around and there is no way to get in, because every venue involves the OS and the OS blocks all such attempts.

If I am too pessimistic, I would be super happy to stand corrected!

I'm not an Apple mystery expert
But maybe this screenshot of OCLP 0.4.11 Night's “CHANGELOG.md” file can help our curiosity.

OK - just getting started trying to use OCLP to update my late 2012 Macmini (Macmini6,1, Intel i5 with 8GB memory and updated to SSD) from 10.15.7 Catalina to Monterey. As implied in my id, I am a relative novice to the world of macOS and MAC hardware, so I am not exactly knowledgeable with the hardware side of things. So I have created both a 16GB USB drive and a 500GB drive system with Monterey using OCLP 4.5, 4.7 and 4.10, and that process seems pretty straight forward. I have a USB attached mouse and Windows keyboard attached to my Macmini, and no matter how many times I have rebooted and hit the Option (left or right Alt key) right after the boot sound I can not bring up the boot selection screen. I have checked the drives on a Windows machine (don't know how to easily do this on a Mac) and I can definitely see the 200MB EFI partition. I have searched wherever I can online and can't figure what I'm doing wrong. So two questions: 1) How and where is the appropriate place to ask for help (do I create a new thread or what is appropriate on this forum), and 2) what am I missing/failing to do? Thanks.

Hm. Just checked. Pane and entry (3rd from top) are there with my 12.5.1 on Mac Pro 5,1. Patched also with 0.4.10.

It gets weirder. Several restarts later the pane is now back, and Media sharing works fine. ???

You are in the right forum, and I expect that someone will answer your question soon.
Personally, I have no experience with Windows keyboards.
Your "using OCLP 4.5, 4.7 and 4.10" is a question mark! You should have only one version of OCLP installed (0.4.10 is best). Did you install OCLP to the USB disk?
If you did not, and have the USB installer disk inserted on boot That could be the reason you are not seeing the boot selection screen. Not sure about that.
If you only installed OCLP to the "500GB drive system with Monterey" (SSD?) disconnect the USB drive and try booting up again holding down the left Alt key. Report back.

Try with the windows or control key. I think they are mapped differently in windows keyboards

Hi, don't be discouraged. First, you don't say if you're using a wired or wireless keyboard. A wired keyboard, in these situations, would rule out the hypothesis that the Firmware does not recognize the "low level" wireless keyboard and that it is not compatible with that Mac.

But oh well... Assuming that your MacMini recognizes the Keyboard at Boot:
1) first you have to try to understand if in your case you have to press the CTRL key or the Win key or another, ALWAYS to the left of the Space Bar.
2) Furthermore, the key should not be pressed "after" the Gong, but it is better to press it a moment before the Gong or during the Gong and it is necessary to continue to HOLD IT DOWN until the icon of the disc or discs with which it is possible to start the Mac appears.

Once you have determined that your keyboard works, regardless of whether OCLP is present or not, you must still be able to see the disk on which a supported macOS system is present.
So start by letting us know if you can overcome this difficulty and if you can always see the System disk.

Having solved this first, it will be possible to help you on the other points.
I assure you that the procedures you have requested will then be very easy to explain as long as your Hardware is working (Keyboard, Mouse and SSD formatted as APFS) which is the first thing you need to understand.

Let us know as soon as you manage to do what I have described. Hello and don't be discouraged.

In my experience, a non-Apple keyboard won't be discovered on low level and useful to call OCLP boot picker. Even my favorite Satechi Compact Bluetooth So my advice is to connect native Apple one for the time of OCLP setting.

First, as in O'Connel's post, the SSD must be formatted as APFS using the GUID Partition Map. I know my Apple wireless keyboard will not call up the OCLP boot picker (probably no wireless keyboard will). So I have 2 keyboards connected (1 wirelss, 1 USB wired, and no issues there).
It should be possible to find a used wired Apple keyboard for a very reasonable price. I don't know where you are located but here in Japan, all of the big stores that have Apple products have bins of used stuff - Apple USB keyboards too - at very low prices. Ask around at the local stores!

OK - let me try to address most of the questions. As I noted before, I am relatively to the MAC environment, but not new to computers. I have been working on PC's since 1981 and been doing Windows support for over 20 years. I am not very good but I have had apps (iOS) published in the Apple Store, so a little familiarity with using macOS.

I am not trying to sound ungrateful, just trying to level set my experience. I appreciate all the help I can get. So let me try to clear up some of the information I may have left out previously - I just didn't want to post a lot of information if this wasn't the right place to do so.

First, both my mouse and keyboard are attached via USB cables, although when operating normally I use Bluetooth for my mouse and keyboard.

Second, I am pretty sure the keyboard is working and recognized by the hardware. I can hit Command (Windows key)-R and bring up the system in Recovery mode. Also, when booting Catalina normally, if I go into Pages and edit a document I can use Option (left Alt) Shift-down arrow to highlight text to the end of the current paragraph.

The documentation I have seen is telling me that the equivalent of the MAC Option key is the left Alt on a Windows keyboard - is that correct?

I have tried with the timing of the boot tone to hold it down through restart, powering off then holding it down through power up and everything else that I can think of/physically do.

I don't have both the USB Memory stick and USB attached SSD attached at the same time - just one or the other.

When I said that I have tried OCLP 4.5, 4.7, and 4.10, I tried them each once. All three times I wrote them to the new media I was trying to boot from. I also have written OCLP to my current Catalina boot disk, but I don't believe that I have actually activated any of them since I can't seem to bring up the boot selection screen to select the EFI partition.

If I go into System Preferences and select Startup disk, I can't see the Install macOS Monterey (right now on my USB attached SSD), only the current boot system - Catalina.

I don't have easy access to a MAC keyboard as most everyone I know uses Windows exclusively. I can probably order one on ebay but I was hoping this would just be me doing something stupid and not needing to wait a week. I am just trying to get Monterey running on my Mac mini so I can update my apps with the current version of Xcode and create a new one that I need to generate passwords according to the security standards of the company I do some part time work for.

Thank you in advance

Kevin

Sorry - Command-R brings up the MAC in recovery mode, not safe mode (already edited in the original message).

 

[NoviceMacUser68]

Sorry - Command-R brings up the MAC in recovery mode, not safe mode (already edited in the original message).

Ok - sorry for the bother - I knew it was something stupid I was overlooking. After looking around for a different wired keyboard I found a brand new Dell (Windows) keyboard and tried that one. Voila! Boot selection screen. After tracing the previously “wired” keyboard, I found that it was a very old wired PC keyboard (purple 6 pin male connector) plugged into an old-style-PC purple 6 pin female-to-USB connector, and that must have been blocking at least the Alt key from registering correctly (as I reported, the Windows-key (Commandj-R did successfully bring up recovery mode.

I am now seemingly installing Monterey on my Mac-mini.

Thanks again for listening and giving me useful hints.

Great you're on the way! Did you use the USB drive to start up? You need to be booted up and start up the OCLP app to run the Post Install Patches. While you are using the USB drive, you can install OCLP on the internal (or external drive, you didn't mention which!) and after running OCLP to build and install OCLP on the internal disk, so you can boot up normally without the USB install disk attached. Of course, you will need to run the Post Install Patches again. With older machines that require post install patches, OCLP will leave an alias in the /Applications folder and move the actual OCLP app to the /Library/Application Support/Dortania folder. If you upgrade OCLP in the future, install the new version in the Dortania folder and run it.
You should be explicit about your install disk, so our comments, based on the info we have from this LONG thread and our experience is appropriate. Is it an internal or external SSD? Internal disks will have the benefits of TRIM but external SSD in a USB case will not. Thunderbolt enclosures do have trim support, but that old Mac Mini has Thunderbolt 1 (up to 10 Gbps) and it is very hard to find an external enclosure that has Thunderbolt 1 (or Thunderbolt 2 which will also work). Sounds like you are in the States and you may be able to find an older OWC external dock with a Thunderbolt 1 connection on E-bay.

 

[NoviceMacUser68]

Thanks for the help. The USB SSD was just being used as a different USB Flash drive to use to store the installation media, and won’t be used after the install. And OCLP was then installed to that drive. Fortunately, my system doesn’t need any post-install patches. The install and subsequent reboots and upgrade (I originally only installed 12.4) to 12.5.1 went flawlessly, and everything appears to be working. So, when using a properly working keyboard everything works as it should.

Thanks again.

[BeatCrazy]

12.5.1 works on iMac11,3+RX480 and iMac12,2+WX4170 as usual...

Who is going to test if the new Kepler patches broke, again? We need volunteers...

Still need testing help? I haven't been following this thread closely, but I had been holding on 12.4 with my iMac 11,1 with a Kepler K2100M.

Thanks, we had already some users running ahead. Everything seems to be fine (unless one has really old vBIOS versions) on Kepler modded iMacs…

If you are not sure about it and need another confirmation create a second APFS container and install 12.5.1 into it. Check the new post install patches there. If everything is fine update your working 12.4 installation.

First update OCLP, than upgrade macOS. Revert the old patches there, update macOS, apply new patches.

Didn't see your post until after I started the update for 12.4 ->12.5.1.

Fortunately everything worked well! Great job guys, I had already resigned myself to thinking 12.4 was the end of the road. Nice to get a few more updates.

Currently writing macOS installer 12.5 (21G82) to a USB flash drive; this is interesting because:
- I downloaded macOS 12.5 (21G82) via OCLP legacy patcher a few times via OCLP
- OCLPP reports downloading macOS 12.5.1 (21G83) but the resulting file is 12.5 (21G82)
- downloading from both the 12.5.1 files available causes the above
- am using OCLP freshly downloaded from dortania Github.

The file is also 12.43GB!

- OpenCore lists macOS 12.5 (21G72) as an option
- Opencore lists macos 12.5.1 (21G83) as two options
- both macOS 12.5.1 downloads proceed correctly (and report 'downloading macOS 12.5.1 (21G83)')
- the actual download is 12.5 (21G82) 12.43GB (so the version number is a hybrid, the filesize is larger, and the 'software version' of the installer is 17.5.02, which suggests it is the macOS 12.5.1 installer)

Will see what happens during an attempted install!

What method did you use to create the installer? I haven't had any problems using OCLP for that. In that case there should be an installer in the Apps folder, where OCLP would find it...

mac OS 12.5.1 + CLP 0.4.10 bluetooth mouse and keyboard become active only after a click ... tell me where to look for the reason!

 

[OKonnel]

mac OS 12.5.1 + CLP 0.4.10 bluetooth mouse and keyboard become active only after a click ... tell me where to look for the reason!

But perhaps is it an Apple choice for supported Macs too?
I assume this because this has happened, for some time, also with my Apple TV 4K and before I can scroll with the remote control trakpad I am forced to click with a button... This always creates a moment of discomfort and I really do not understand why they did this stupid choice. Maybe to save batteries?...
But this only happens with the Mac or Apple TV just turned on.
And thank goodness..
