macOS 12 Monterey on Unsupported Macs Thread

[internetzel]

Nope, finally it failed…
Anyone any ideas, what I could change?

Seems strange that is fails to find "ARM base system patches" - OCLP people should take a look at this, if it repeats to fail like this while installing onto a formatted disk.

For what its worth. Monterey still runs fine on a test disk. Still haven't upgraded from 11.6.3 yet. When I do decide to upgrade is it best via OTA software update or bootable installer? Monterey was a fresh wipe/install on the test disk with 12.0.

When using APFS on rotational disks I think it's normal. Keep waiting at least as long as you can hear the hard disk working.

APFS on non SSD drives is a terrible idea.

Anyone on 12.3b1 on a 4,1 or 5,1 cMP lately?
I only noticed some 3,1 owner reporting trouble and then success with the PM fix in 0.4.2N.

I sussessfully updated from macOS 12.2 (final) to 12.3 Beta on my CMP 5.1 (flashed 2009), using config that compiled by OCLP 0.4.2NB (now released)

Spoiler: MacPro 3.1 - macOS 12.3 Beta1 -Benchmarks

Spoiler: MacPro 5.1 - update OC config and macOS to 12.3 Beta1

Out of curiosity, could someone post an SSD performance test (Aja or blackmagicspeedtest) of their mbr 13" mid 2012 system please. I wonder if an SSD upgrade could be worthwhile apart from gaining some more space.

This number tells you NOTHING about the speedup when using an SSD. It is all about access time and not about streaming performance, which comes only into play if you want it store terabytes of data onto the disk. But tell me how to feed that amount of data into the disk faster than 300mbyte/s

Not always.

I use APFS on an external disk that has multiple volumes for time machine backup for my macs connected and over the network.

Works fine, especially appreciate the volumes all sharing one big disk.

Now happened for the third time, that it failed with „12 minutes remaining“.
After that there are 12,09 GB written to the harddisk :/

Any ideas apart from HDD is a bad idea? I have only one SSD here and there is my productive Catalina on it

It Suppose to be work ! I have many Installation on External Mechanical HD
Make sur formating the HD like this on your mac before booting and installing from USB Install Media

Dear All,

I have an iMac13,1 with OCLP 0.4.2, Monterey 12.2 and everytime I boot up, I run into the following issue: "Waiting for remote debugger connection" and the system freezes. (See screenshot). I tried re-patching, but no success. Any solution for that?

Thank you!

Honestly that seems kinda low, my 2TB in mine hits 450/500's. Mines running 11.6.3 perfectly.

Wow, thanks for the effort of making this video!
However, I already formatted the whole drive using APFS with Guid partition table So, nothing I can improve at this aspect.

OK so try to format Like this

then Installer macOS will be convert in APFS during the process installation

here's my 13" Mid 2012 with single SSD (500GB) vs RAID0 (256GB x2 ) setup performance.

Absolutely right, and the seek/access times will make a huge difference, even on SATA-1 interfaces. If you once booted your system and ran apps from SSD and you go back to spinning drives, you really think your computer is defective in some way. Had that experience a lot of times when reverting back for test purposes or installation experiments with "unsupported" builds on old Macs.

Even a Macbook pro 17" 2008 it´s a huge improment with a ssd.

I always wanted to do R0 in mine, but I had misadventure with APFS and R0's on a MB 7,1 so I never tried with the 9,2

Indefinitely so! I put 6GM of RAM, a compatible WiFi-Card, and an SSD into my MBP4,1 Early 2008, 17-inch. The machine is running Monterey like it is built for it. 13-yrs of age and no wear or tear. Exceptionally good hardware.

If I were to use OCLP to install Monterey on my iMac 15,1 (27 inch late 2014), will I get Mission Control (once it's out of beta) or is there an additional hardware requirement that won't be met?

(I only care about Mission Control so I won't bother otherwise.)

 

[TimothyR734]

yes mission control works in macOS Monterey

Well
What should I say…
So, first of all, that indeed was a superb trick! The installation was again on „12 minutes remaining“ for a very long time but then it jumped to 18minutes, then 1h 18min, then it went on, the MBP restarted.
Then the progress bar with the Apple logo appeared.
There it ended with „Less than a minute remaining“…
However, after 4 hours it still showed this
I cancelled the installation now.

Any ideas, what is wrong, if „Less than a minute remaining“ never goes away?

Check anyway if all macOS Monterey is Install and complet installation?

There was no bootable OS after my „forced shutdown“.
Just the EFI Installer from my bootable stick.

Disk utility showed 2 APFS volumes: HDD and HDD Data. HDD Data had 12Gb on it

Do you mean ”universal control” ?

 

[the.burn]

And again, install failed at 12 minutes remaining Now it’s this error:
