macOS 11 Big Sur on Unsupported Macs Thread

[0134168]

Just inherited a broken Macbook Pro 2010 17". Repaired it and installed Big Sur 11.4 by accident, as I replaced the Hard Drive with an SSD with a backup of 11.4 and Opencore. Worked perfectly. Confused, but elated. Wiped it and reinstalled 11.2.3 instead and used OCLP after the install. Again works perfectly, except backlight. Weirdly before OCLP, backlight was working but screen brightness was not. After OCLP, it's the other way round. Not bothered really as I'm still amazed Big Sur works on it at all.
This will be my daughters machine when I have installed Windows 10 bootcamp. Thanks to everyone who created the OCLP.

From what mac was the backup of 11.4 and OC?

"intel® be gone" - Apple®. To be clear - Messages, News, Stocks, FindMy and VoiceMemos apps will no longer run in macOS 11.5 on a true Legacy Mac lacking a Metal GPU.💩

My Bluetooth dongle (this: http://www.logilink.org/Products_Lo.../Bluetooth_40-Adapter_USB_20_Micro_BT0037.htm) that has been working fine on my MacPro5,1 with Big Sur is not recognized anymore since going from Big Sur 11.4 to 11.5.

Any ideas?

The computer don't think there's any Bluetooth hardware connected when in Big Sur 11.5 (Bluetooth in menu bar has a line over it). If I start up in Windows 10 it works fine, so it's not a hardware problem.

BEWARE!! macOS 11.5 breaks stuff!

What changed? Do you know? 👀

As of macOS 11.5 , rename OCLP to OCMP to be correct. No longer a "Legacy Patcher" if Metal is required. FWIW

Apple most likely changed some frameworks and internals which break the Message app on non metal systems and you complain about the naming scheme of the single patcher working with legacy systems? This is not a patcher problem and the tools has not caused this. BTW: All 2012 to 2014 systems are legacy systems, too.

My Mac Pro 5,1 carbon copy cloned (version 5) backup disk. It was a Martin Lo Opencore 0.6.7 Version with Innie embedded into Lilu for the NVME to be seen as internal.

 

[macrumorsnumpty]

I know it's probably a pain but has anyone got backlight to work with OCLP?

The machine is a 17 Inch mid 2010, 2.53ghz Dual Core Intel i5, nvidia GT330m

So, you don't know what changed? And is the question here and not the snark. macOS 11.5 wounds lots of old Macs and is met with a shoulder-shrug? Seriously? If this had the equivalent effect on cMPs, hackintosh or iHacks this would already be fixed. 🙈

I have decided to stick to 11.4 on my old imac mid 2011. I believe unless the update is surely required then proceed or else just enjoy your old mac. Most of the apple updates just has few changes so its always good to read what apple is changing before updating your unsupported system. Sometimes the updates only breaks things. All the best.

Apparently Messages needs a metal GPU on 11.5, see issue #405.

Looks like the most current 0.2.4 build of OCLP has fixed Messages.app crashing in Big Sur 11.5.
(Don’t know if this is especially a fix for non-metal graphics or a more general one, though.)

Confirmed - latest OCLP TUI Nightly returns the apps 10.5 killed since Beta 1 to normal operation. Looks good, so far. Big thanks to @khronokernel and @ASentientBot for implementation. 🥳

macOS 11.5.1 just dropped. Not a beta.

The July26 midnightly OCLP 024 TUI holds up nicely on macOS 11.5.1. Everything intact from OTA update over 11.5. Brilliant. 😎

OTA updated my MP3,1 running OCLP Big Sur 11.5 to 11.5.1 with no problems although required two manual restarts during the process.

macOS 11.5.1 is working great so far on an iMac 12,1. Amazing to be able to run this on a machine that's about ten years old.

Smooth incremental update via Software Update from 11.5 to 11.5.1 in my iMac 11.5 RX480 booting from OCLP 0.2.4.

I´m having problem with some apps. its a 1/10 that the app actually displays anything in the window. I have to restart the app over and over again to eventually get anything else than a empty gray or white window.

Anyone else with the same problem?

After like 10 tries it eventually shows the app.

Im back from the "dead" if youd say. Its been forever but this time im back for something different. Iv been researching for a while now and had the nerves to purchase a gt 710 2 gb from pny. Do you guys have any idea if 1, Will Mojave be supported without having to use ways around, 2. Boot screen possible? 3. How will the performance be in Big sur and if I ever do decide to update to the newest. Im running a 8 core MP5,1 (Mac Pro 2010) Im focasing on big sur tho. Thanks in advance!

I personally have a GT710 in my MacPro3,1, though I do not daily drive it (RX470 instead). macOS Monterey supports Nvidia's Kepler series just fine however boot screen support null. OpenCore Legacy Patcher can partially get around this by restoring boot screen support once you load it in UEFI. This will provide a boot picker which you can select OSes easily

My process is boot OpenCore with a boot screen GPU, this will install itself as the default boot option and so I can shut down. Afterwards I can swap my PC Card in and get output once OpenCore loads

Would there be any issues running big sur? Or is it fine?

Question: I'm currently running Big Sur 11.4 courtesy of OCLP 0.1.6

##################################
# OpenCore Legacy Patcher v0.1.6 #
# Selected Model: MacBookPro10,1 #
#     Target OS: macOS 11.0      #
##################################

Now I'm wondering whether I should update OCLP to the latest version before attempting an OTA update to BS 11.5.1

Any comments much appreciated.

I'm running 11.0.1 after using one of the patchers very early on.. One that patched the BIOS... I've backed up, and I'm tempted to try OpenCore Patcher now, despite probably having to start somewhat from scratch..

Now, umm.. how likely is everything to break and is there a huge difference between 11.0.1 and 11.5.1 ? Got to admit the idea of OTA updates is pretty nice! I haven't known how to safely update at all since the initial 11.0.1 install.

I'm on an iMac 14,3 ..

I also have one very specific hardware issue that might wreck the install process. I have a half broken fusion drive, the SSD part i use as a 128GB scratch disk but I've found that if the system tells the the drive to sleep it freezes/reboots.. So during an OSX install i often get some extra reboots. (they've always ultimately worked great though) Once I'm into MacOS I can just tell it to never power down the half broken drive.

I can't decide if I should risk this as getting it to boot again afterwards considering my 11.0.1 install is hacky.. If I break it i might not be easily able to get it running again? 😕

After those fix1 and fix2, could you try also to replace these to check which works better :

prelinkedkernel MacBook4,1 all kext without LegacyUSBInjector

prelinkedkernel MacBook4,1 all kext with LegacyUSBInjector

sorry for super late reply, i tried like some weeks ago and with usbinjector worked

 

[HexagonWin]

maybe can you tell the way to get a booting ordinary bs install in here with a patch or something? In current state the prelinkedkernel keep needs to be remade by you when doing kext things, which isnt really comfortable for testing
