macOS 12 Monterey on Unsupported Macs Thread

[MacRumors3590]

I had to remove OS12 from the 9,1 iMac as it started to go into a standby loop where it kept going to add password Lock Screen then major lag then lock screen again. I've now dropped it back to Big Sur which works perfectly.

This happened to me as well and I simply re-installed B8 over the top and now all is well ?

After a couple of days with 21A5534d on MBP9,2 16GB Ram:

Up until now pretty much each build was snappy, easy to use. This one a different story: It become literally unusable.

Bluetooth audio stuttering, mouse comes on goes away literally 10 times a minute, copy rates between internal sdds became horribly slow. Safari is a nightmare. Takes up huge amounts of RAM without having even a page open. Sometimes the whole system seems to freeze up for minutes.

This build is definitely not ready for prime time.

There are still some bugs with beta 8 running in my iMac 2010 with Metal AMD GPU and OCLP 0.3.0n.
Sometimes, the dock is not responding completely on clicking, but applications can be launched in the Applications folder.
Sometimes, the volume icon on menubar is crossed out despite the internal speakers are working.
So, still not stable enough for daily use.

Thank you @trifero!
Maybe my error was erasing the SSD as APFS volume before installing? I would format as macOS Extended (HFS+) with a GUID partition map...? Or maybe SIP was enabled? Or both... Idk... I will try to install Big Sur 11.6 in a couple weeks or wait for Monterey final release when it comes.

Not at all. Even if you formatted as HFS+, it will convert to APFS.

I've rolled back to beta 4 using the original installer USB stick so I can at least boot Monterey to grab the next showstopper-free update. I'll let somebody else test it first.

The Monterey Betas installed from USB createinstallmedia seem to be more reliable than OTA installs? ?

 

[Mac_tech]

all i know is with my MBP 9,2, Monterey Beta 7 was SIGNIFICANTLY slower than Big Sur 11.6.1. I'd rather just wait for the full release of Monterey and do an OTA update to that with the proper kext patching if necessary

Apple released beta 9 to developers today. I wonder if it helps with performance at all

 

[Ausdauersportler]

Beta9 OTA succeeded using the VMM flags manually added to OCLP 0.2.5

 

[Tockman]

Update is found at my System Preferences, but it's full 11 Gb, not Delta one. It happened for the first time since Monterey on OCLP. Yes, I remember that it's normal on patched system volume but... during update to Beta 8 I was offered with Delta, though volume was already patched.

UPD.: Oh no, I may be wrong because last time I didn't see download process, but polite proposal to restart for update. May be, that time it was full installer, too.

I don't know for sure, it's the first time I've rolled back by reinstalling with a USB stick I'd used previously. What I can tell you is the reinstall went flawlessly. Even better, bluetooth was still working; when I first installed beta 4 it was not.

edit, later: I see beta 9 has just been released. OTA is still offering me beta 8 so I'll wait. Looking good so far, see the Monterey external monitor thread

Just over-installed Beta 8 createinstallmedia USB on top of a flawed Beta 7 OTA install. Two hours and no cascading app crashes, so far. ?

Interesting point you raise about the possible lesser reliability of OTA versus createinstallmedia. I wouldn't be surprised if you were right, given the inherent additional complexity of OTA

Saw this in beta 8. Doing an OTA upgrade to beta 9 didn't help.

From beta 8 installation: MBP10,1, macOS Monterey Dev beta 8, full install, OCLP 2.5-TI app (and 3.0, too, run from command line), default settings ==> bootable Monterey, but:

• white Apple logo & thermometer pop to shrunken size at last stage of boot,
• internal Retina display is running at "full" resolution, I.e., 2880x1920 (IIRC), with all Finder icons, menu items, etc. at tiny, shrunken size,
• Sys. Prefs. Displays for Retina display doesn't respond to Scaled mode, no other resolutions shown.
• Externally-connected display, on HDMI port, doesn't light up and is not shown in Sys. Prefs. Displays either.
• Haven't seen this with earlier betas.

Anyone else see this? Recommendations? Non-default OCLP settings to use?

TIA,

Mike

All of us on beta 8 are seeing that. Welcome to the club. Beta 9 is what we're all waiting on.

 

[Jordillav22]

Beta 9 installed on iMac late 2012. Software Update. Everything seems to work well. No problems.
OpenCore 0.3.0

 

[0134168]

I´m gonna try Beta 9 in my Mac Pro 5,1. Beta 8 was imposible to install, video problems.

 

[KennyW]

Successful incremental update to beta9 with no issue.

 

[0134168]

Beta 9 is a disaster. No trackpad clicks in a supported mac.

Reinstall post-install patches and adjust resolution

Updated MacBookPro6,2 correctly using OCLP VMM edition (hence without spoofing firmware and smc versions) from beta 8 to beta 9 , since it's a non metal acceleration Mac the panel prompted the full OTA 11,01 GB , here are the phases I encountered (downloading time excluded):

- Preparing OTA update (directly from desktop) estimated time 35 minutes but took instead twice
- Auto reboot OTA stage1 SU x86_64 ramdisk took about 15 minutes
- OTA stage2 not shown minutes remaining but took about 30 minutes
stuck on stage2 with full loading bar then forced power off and reboot with CMD+V this showed that stage2 correctly proceeded with mainly these verbose:

patchd Checkpoint begin macos_install_recovery
Ramrod_display_set_granular_progress_forced : from 23.000000 a 100.000000

- auto reboot weirdly to the Recovery BaseSystem which completed a loading bar showing only the apple logo and mouse cursor
- auto reboot outside to the BaseSystem with direct boot to desktop
- first login after update took about 10 minutes

anyway everything worked as expected, so I guess the new OCLP VMM is a reliable and advisable method to update and install Monterey.

I add that apple recompiled all core system files on first October and as some already reported with this beta 9 (build 21A5543b) they also added 8 dynamic wallpaper pictures for the vectorial Monterey (attached with reduced quality as example), so maybe this time they might not add a dynamic landscape photo as default desktop.

Beta 9 is a disaster. No trackpad clicks in a supported mac.

Which one did you try it on?
On my M1 it works flawlessly ;-)

 

[Tockman]

"macOS 12 Monterey on Unsupported Macs" if the name of the thread.

Now, come on. Original poster started with "does not work on a supported Mac". I asked on which one, politely. Gave my info that it works on the (supported) M1.

 

[Tockman]

You started with "does not work on a supported Mac".

I, personally, didn't start anything.

Right, I corrected it. But what is your message then?
