macOS 12 Monterey on Unsupported Macs Thread

[unclemiltie]

OK, an update. I finally got this system working but it was a serious challenge

Things I did:

• initial install was a High Sierra install, migration from el Capitan mini, OCLP install of Monterey 12.1, Wifi card did not work
• erased SSD and installed Monterey from same USB on a clean disk, wifi card did not work
• re-installed HighSierra, Wifi card worked fine
• built a new USB with 12.7.5, erased SSD and installed using OCLP. WiFi worked
• Tried to use migration assistant from El Capitan system direct to Monterey. I've had issues with this before that the system starts to boot, gets about half way done and then restarts. Rinse, repeat. Yup, happened again
• Went back and re-installed High Sierra, did the migration from El Capitan and then used the same USB to install Monterey 12.7.5. Success

This is not the first time I've had issues with the migration assistant on Monterey not liking older versions of MacOS BTW, there's another thread in here about it (or is it in the MacOS generic thread?)

But in the end the system is up and running with all of the software migrated and installed. Gotta re-enter some keys but it's all there.

Thanks for the suggestions to those who gave them. And in case someone comes across this thread, it was something to do with the early versions of Monterey and the WiFi card on the iMac 12,2 that caused it to not work

MacBook Pro 13" Mid 2012 - Monterey 12.7.5 - OCLP 0.4.11 - Everything works.

On a different note still trying to figure out how to make Bluetooth an WiFi patches a more permanent "on the disk" root patches. It seems that the first developers beta had easily patch-able Bluetooth and WiFi but then the amount of dependencies grew exponentially.

I have a MacPro 4,1 that has High Sierra installed in it. It been a long time but I think I accomplished that with dosdude patch. This system has always worked great, no missing functionality that I can find.

Wanting to upgrade to the newest but most reliable macos. Need the sleep function to operate properly as we use this a lot to cut down on power bill (makes big different as the cheese graters use 250w+ if they are not sleeping).

What macos should I upgrade to for a mostly problem free experience ?

MacPro4,1 x2 3.46ghz 6 core
64GB RAM
evga 980ti video
OWC Accelsior S PCI 2TB SSD

Thanks for any info.

The information you provided doesn't match, if its still a 4,1 there is no way you could have high sierra installed as el capitan is the last stop unless its flashed to a 5,1. (maybe there's a way that i don't know about)

 

[RumorChaser]

As Monterey is marching towards the end of support, there is some good news. At least Sequoia supports Intels Macs, which means it is highly likely OCLP will support at least the Metal based Intel Macs (2012 on).

 

[xxcfdrr]

Sorry for the confusion, it's a 4,1 but was flashed to a 5,1.

I've been trying to install Sonoma on it and presently it's skipping over the boot selection screen when you hold down the 'option' key. It did give me that boot menu a few times after a few power off, restart but the latest message was that ' This copy of macos Sonoma is corrupt and usable' when it started to finally install. No harm done to the system as I am trying to install it on an extra hard drive in the mac. I may try the same process today but try Monterey instead of Sonoma.

 

[xxcfdrr]

Tried to install Sonoma again this morning and get this message. Screenshot below.
Just to be clear, I created the OCLP install media on a USB twice, just to make sure it wasn't corrupted the first time it was downloaded. Both times I got this error message. Speaking of the USB, I used a 32GB micro SD card in a USB adapter. Wonder if that's a problem ?

Help, I tried to upgrade my Big Sur installation to Monterey and now it's stuck in a recovery mode boot loop. I tried removing the OC EFI, resetting PRAM, reinstalling OC, reinstalling Monterey like the troubleshooting docs say. Also tried clean installing Monterey, and Ventura, to a separate volume and got same problem.

Weirdly I was able to install Monterey to an external USB drive and I can boot from it and it works perfectly. Why doesn't my internal drive work, but my external does?

I also have a Bootcamp partition if that makes any difference. Is there something I need to do to make OCLP and Monterey play well with my internal drive? I didn't have any problems with Big Sur.

 

[eablokker]

I finally got Monterey to boot on my internal drive. Posting here in case anyone is looking for the solution.

First I thought maybe it was because I have a UEFI Windows installation, so I followed the UEFI Windows instructions and moved my OC EFI to its own separate 200MB FAT partition and removed the OC EFI from the APFS partition using the MountEFI tool. Well, that didn't help at all, even tried reinstalling Monterey again but no luck.

Finally I erased the entire APFS partition and did a full clean install of Monterey. Bam, that worked! Now it boots into Monterey. No idea why, but hey it works. Proceeding to restore everything from my Time Machine backup.

UPDATE: Nevermind, after restoring from Time Machine using Recovery Assistant it went into a boot loop. Not booting into Recovery this time, just rebooting over and over during the loading screen.

UPDATE 2: Reset PRAM and SMC, it finally booted, but into the Migration Complete screen. It did get stuck at halfway for a long time, but just wait, it eventually brought me to the Migration Complete screen. It asked me to reboot again and went into another boot loop bringing me back to the Migration Complete screen. Tried resetting PRAM and SMC again, but now stuck in this migration complete boot loop.

UPDATE 3: Hidden in the OCLP installation instructions it says you cannot use migration assistant when root patches are applied. So this time I installed Ventura instead and when I got to the setup assistant I restored from time machine. After complete, I boot into Ventura, and none of my files have migrated. Where did they all go? What was all that copying for? They're just not there. Instructions say to "avoid restoring from inside Setup Assistant". Damn, I did it from setup assistant. Maybe I try again after removing root patches and using Migration Assistant again.

Just to follow up about my screenshot error in my last post. I was trying to install Sonoma using a 32GB micro SD card in a USB adapter. I tried again with a real 32GB USB stick and it worked fine. Now the only problem is Sonoma is completely unusable as the evga GTX 980 has no drivers and it's so slow the computer is impossible to use. I think I'll just buy a newer MacPro and be done.

AFAIK compatible video card is cheaper.

I have a WX7100 out of a Dell. Will this one work? It's a bit confusing regarding the video cards.

Hi

I am backing up some data from a mac mini server 2010. Its OCLP 1.5/Monterey 12.7.5. The backup drive is connected to a dock via firewire 800 or USB (2.0).

I have two 3TB drives that are marked as 'failing' (driveDX) but they still basically work and are usually fine for the immediate backup task even if they might die during the copy/restore. But curiously when mounted they read in diskutil as 801.6GB in size, but after terminal notes there is 3.0TB free space?

Same with USB connection to the dock - although obviously I would prefer FW800 for speed.

Is this an OCLP related issue? Two 1TB drives I have in the same 'failing' pile all work fine and correctly read as their 1000GB size.

Other differences: neither of the two 3GB drives will mount by themselves. DiskWarrior and Disk Utility mount them as 800GB drives. They erase fine, rebuild directory fine. Just only 800GB worth.

Also I cannot 'hot swop' the 3TB drives in the dock but I can with the 1TB. Inserting a 3TB will freeze the mac, and it will do the same when powering up the dock with the HD inserted while mini is running. The drive *must* be in the dock and switched on when the mac mini boots to prevent this.

Any ideas about what's happening here?

AFAIK compatible video card is cheaper.

Is there a list of compatible video cards? It sounds like I need to buy a very specific video card (with boot screen) or buy a new Mac, please let me know. Thanks for your help.

 

[tennisproha]

Is there a way to get Apple Watch to unlock my non-Apple Silicon Mac, using a 3rd party app perhaps?

I can use the Watch to for password prompts once I'm logged in but it won't work to unlock the Mac from the Lock Screen

BGood evening, I have a Mac Pro 5.1, I bought an RX 6600 I did the ROM modification process on a PC then installed it on the Mac, when I turn it on it doesn't recognize the card or the acceleration

 

[Rico Muerte]

Hello friends, I have a 2012 (non retina) MBP as my daily laptop on Mojave, & was interested in updating to Monterey which is not natively supported - curious is anyone else has installed OCLP & Monterey on their 2012 MBP, & what general day-to-day performance is like...?

Thanks

1. Keep Mojave. (In fact, create a new MacOS extended (journaled) partitiom (AKA HFS+) on the same or other drive using Disk Utility, then use Carbon Copy CLoner 4 or 5 to duplicate the boot drive into the HFS+ partition. Reboot into it via Option at boot to verify it works, then erase and recreate (as HFS+) the original partition, and move it back. Much faster than APFS default.)

2. You will lose access to a TON of software, some that you're probably using right now, as it's 32bit, and Mojave is the last version of the MacOS to support it.

3. If you need a "modern" browser, get Chromium-legacy and install uBlock Origin and Adblocker Ultimate browser extensions into it.

 

[Bigwaff]

@Minghold points 2 and 3 are good ones, especially about 32 bit software. What software do you use on Mojave?

Regarding @Minghold point 1… some clarification is needed… at least to me. It’s not clear to me why making a duplicate of your “boot drive” to “the same” drive is helpful and what that has to do with being “much faster” than APFS… unless your MPB has HDD instead of SSD for internal storage?

 

[MBAir2010]

My same MBP (16gb i7, 2.9 GHz) ran OCLP Monterey great for 4 days,
then crashed every reboot and start up in 2022 were i had to erase the drive.
i did have issues with small thing i forgot since that was a while ago and reverted to Mojave then boxed the MBP until 2 weeks ago.

I would obviously time machine what ever you have now then try the OCLP.
the process is time consuming but the weather is perhaps too hot or too rainy where you live,
so why not try that project?

i hope this helped!

As for me and my MPB2012, i am using Mt Lion with SeaLion as my web browser and will use this MBP all july.
as far as Catalina, that was too hot even with "macfans" blaring while mojave (a great OSX) is on a separate drive resting now. Since is stopped all icloud and air services, i don't need a modern OS.

 

[Minghold]

@Minghold points 2 and 3 are good ones, especially about 32 bit software. What software do you use on Mojave?

Damn near everything. Got over 200 apps on a 165gb worth of boot drive space. All the great old stuff, before features were chopped on in the "new" versions. By number (not drive-footprint), about 80% of them are 32bit, including oodles of utilities that are under 100k in size. (Apple has done its utmost to erase from collective memory the fact that you could once download Mac software from all over the place, and the community was thriving. In their future, there will only be the AppStore, and they exact a toll.)

Regarding @Minghold point 1… some clarification is needed… at least to me. It’s not clear to me why making a duplicate of your “boot drive” to “the same” drive is helpful and what that has to do with being “much faster” than APFS… unless your MPB has HDD instead of SSD for internal storage?

Mojave runs considerably faster in HFS+ than APFS, where is just kinda pokes along, and it doesn't matter whether you're on a hdd or ssd. Also, in HFS+, everything is in one volume (i.e., same as High Sierra before it). It really is the last "real" versions of the MacOS, with all successors bastard imposters. The sad truth is that new Macs are really a whole separate thing stuck in their own gatekept subscription-model romperroom. People bring their computers to me to solve issues, and they'll have like four things on it that aren't built-in Apple iWidget ecosystem (and one of those is Google Chrome and one of the others is student-edition MS Word, and a third is a Steam portal), and I'm like why did you buy a new computer to do nothing on it?

We are in the dark days of Mac: every month, another 'net repository of old software goes offline, and what your parents did for free on their computers costs you $19.99/mo on yours.

SnowLeo or even Leopard.

I always liked Tiger. (Snow Leopard definitely had the best cat desktop pic.)
