macOS 11 Big Sur on Unsupported Macs Thread

Does Sidecar require spoofing?

Can't see sidecar on my my mid-2014 rMBP running Big Sur via OCLP v0.4.2

Sidecar support is based on FeatureUnlock. This might be disabled by OCLP in some cases.
Check you config.plist and boot-args.

I have successfully installed Big Sur using OCLP on an early 2011 MacBook Pro 15" and I am very impressed with how well it runs. Like most 2011 15"s my AMD GPU no longer works and I have special grub parameters for when I need to boot Ubuntu but now holding down the alt key at boot and selecting "EFI Boot" causes Ubuntu to boot withou these parameters and so it crashes. Is there a way to fix this, I used to use Refind but it looks like it doesn't play well with OCLP. Has anyone else managed to do this?

May be this version of refind plus does the job? You may try reset the PRAM before booting into Ubuntu using grub.

I checked my config.plist and it was enabled. I guess I’ll need to figure out checking the boot-args.

You can use OpenLinuxBoot.efi driver released with OpenCore to boot Linux via OpenCore. Should be as capable as rEFInd at booting Linux directly.

Add autoopts="....." to Arguments for the driver if you need to replace the auto-detected kernel options, or autoopts+="...." if there's a specific additional parameter which you need to add, to defaults which are otherwise okay.

Thanks to all that replied to my question. I eventually used the OCLP instructions to add the ext4 drivers to opencore and then edited the bless_override parameter in config.plist to allow grub to boot from opencore. Because of the broken AMD dgpu, I also had to edit the boot parameters to stop activating the radeon driver. For good measure I also blacklisted radeon to stop it being loaded on boot. So far dual boot using opencore is working fine.

Glad it is working. OpenLinuxBoot is the slightly recommended option - at least by the OC team. 😉 But chainloading to GRUB should also be fine. However, in a normal setup, you do not need the ext4 drivers if you are chainloading to GRUB, it should work without them.

I tried OpenLinuxBoot first but it didn't see Ubuntu so I just kept fiddling until it worked. 🙂

Maybe it is something in your ScanPolicy? Or possibly you have a standalone (i.e. separate mount point) /boot partition, although that is not standard in Ubuntu. Would need to see debug log to understand more - but perhaps not worth it if you're happy already. 🙂

Tried it last week with a dual boot in dual disk (Monterey and Ubuntu) and had to add the ext3/4 driver to OC (OCLP) to get it working.

Did not know there would be another more easy way.

OpenLinuxBoot.efi should be the easy way, though it does require loading the ext4 EFI driver as well (because OLB.efi can only work with file systems which OC can 'see').

Chainloading to GRUB is the less easy way (often more manual setup, won't look or work as nice within OC once it is set up), it does not require the ext4 driver (for all normal distros; since the initial GRUB loader is normally on ESP) (and just to be clear, it does not require the OpenLinuxBoot driver at all).

11.6.5 by OTA Update from 11.6.4 (OCLP 0.4.2 spoofless) on Mac Pro 5.1

(just a machine in progress, most untouched, stock wifi, stock bluetooth)

 

[Earl Urley]

I updated my MP 5,1 to 11.6.5 as well OTA. For some weird reason I didn't see the 'Macintosh HD' psuedo dissolving update volume on reboot, and I had to do a PRAM reset in order to get the update thermometer to progress; two cold boots seemed to kick some sense into the updater and eventually I booted to 11.6.5 successfully.

Don't know why it was glitchy this time around, the update to 11.6.4 didn't give me any trouble.

Also running OCLP 0.4.2 but with minimal spoofing; 11.6.5 also seemed to fix some issues I was having with WiFi Sharing.

Hi all
cMP4,1>5,1 successfully updated from 11.6.3 to 11.6.5 with OCLP 0.4.1 via full installer on USB stick.

 

[ivankuraev]

Updated iMac14,1 from 11.6.4 to 11.6.5 (20G527) OTA. OCLP 0.4.3.

MBP5,2 17“ mid 2009: Updated OTA from 11.6.4 to 11.6.5, and from 12.2.1 to 12.3 on two partitions of the internal SSD. Using OCLP 0.4.3 release in both cases. Went smooth and automatic (and showing the Macintosh HD in the OCLP boot picker on 1st reboot).

I had exercised the release candidates for a while on external SSDs before.

The books.app of 12.3 does not run well without Metal. Replaced it with the BS version 3.2.

I can go back and forth between BS and MR relatively easily by using a set of scripts with rsyncs to keep important user data in sync. BS is perfectly stable und MR is getting better and better.

It is great to have OCLP. Many thanks!

MBP8,1/11.6.5/OCLP 0.4.3: Everything o.k.!

 

[mwidjaya]

OTA to 11.6.5 and all is well. Currently still on 0.4.2.

Hi all

A bit off topic but I created some themes for OCLP and openCore

3D_Squared-OC-Themes



3D_Rounded-OC-Themes

 

[Bmju]

@alphascorp Nice themes! There is an InsanelyMac thread for OpenCanopy icons. (I believe there is not one on MacRumors.)

Hi @Bmju
Thank you
Yes, you are right, there is no such thing on MacRumors, but I am following this InsanelyMac thread with great attention

Hi all

3D_Squared-OC-Themes
3D_Rounded-OC-Themes

Thanks @alphascorp! And could you please tell where to find the instructions to do it? Or maybe you could publish the two themes in one or two ZIP files attached? Thank you. PS: the background with the apple is very nice...

Hi, I have installed big sur with the latest version of OC but the performance of my imac 27 mid 2010 i7 is low
I noticed that the GPU sensor cable has broken
Could this be it?

Useful information to install macOS Monterey on Catalina 10.15.7, obtaining an excellent result, without wasting time with USB sticks... I specify that I have an iMac 14,2 (27-inch late 2013 with CPU i7, 24 GB of RAM, nVidia GeForce GTX 780M with 4GB VRAM)
So yesterday, in my main 2TB SSD, I wanted to try switching to Monterey straight from Catalina to see what would happen. If there was any problem, I was ready to reset the Mac using Time Machine.
Is it worth it?... I anticipate the result: the answer is absolutely yes

Obviously it is necessary to have already installed OCLP on the EFI partition of the internal disk and, for this purpose, I used OCLP 0.4.3. But be careful because it is essential, in creating EFI Build with OCLP, first select Settings -> SMBIOS Settings -> SMBIOS Spoofing Level and set -> Minimum Spoofing. Or the Apple's Installer app doesn't recognise the Mac as "supported" and so refuse to install Monterey.

At this point, after downloading the original Apple macOS Monterey installer package (thanks to https://github.com/corpnewt/gibMacOS), I created the riginal app to install Monterey which the Installer places in the Applications folder .
That's it, then:
- I started "Install macOS Monterey.app" from /Applications/
- I waited for the Mac to restart after the installation was finished
- I ran OCLP again
- I have selected and started the OCLP "Post Patch Installation" option.
- I restarted a last time the Mac and...
...now I have a feeling that Monterey, installed with this "original" and natural for Apple method, it seems to run smoother than Monterey copy I was using, until now, with the other 128GB internal Apple SSD in mine iMac. [Note: this is the SSD Apple of the "Fusion Drive". Fusion Drive that I had abolished some time ago, separating the two disks and inserting a fast 2TB SSD in place of the mechanical HD].

I add that now, in the usual uses (Finder, Photoshop, Office applications, etc.), my Mac looks as snappy as a new Mac and I think that even the new Mac Studios cannot go faster than that, since the System is already at the physiological speed limit of the Finder and other apps.
Surely the difference with the new Macs we would see well for example working with video files and Final Cut X or in other things, for example in 3D ... But this is obvious ... I'm not naive or stupid ...

Basically, after installing Monterey on Catalina I found everything in its place! Two only examples.
- The tens of thousands of e-mails, which I keep in Mail, did not need to be imported again, as it happened in the past when changing Operating Systems; Monterey, in fact, just renamed the V7 folder to V9 in the My_Home / Library / Mail / folder.
- Time Machine also continues to run in JHFS+ format and keeps full backup of the old system with Catalina. [Note: With Monterey, in fact, when you create a new Time Machine, macOS automatically applies "APFS File System case-sensitive" and also no longer backs up System files as it uses a different recovery mode].
Of course, as soon as I'm sure I don't need to go back to Catalina anymore, I'll let macOS Monterey create a new Time Machine in case-sensitive APFS format that is better and better of JHFS+ even using a mechanical disc. I have tested this option, in fact, for a long time using Monterey installed in the other internal SSD and I have no doubts about it.

That said, I hope I was helpful.
For the nerds, I add that wanting to be picky I will now install an OCLP EFI build created without Spoof. The Spoof, in fact, even if "minimal", makes use of many Kext and redundant settings that are not present, however, in the Buid created with the default OCLP setting; Build to which I always manually remove what concerns the Airport Boadcom module fix since in my iMac this is not needed.

Yes, a single missing temp sensor throttles the CPU (and GPU) down. You need to reconnect the plug or get another heat sink. Has been described a thousand times on the GPU thread, too.
