macOS 11 Big Sur on Unsupported Macs Thread

[eminemmm]

Look at @eminemmm's previous posts. It's a 13" 2011 MacBook Pro. It's HD 3000 only. It's not a dual GPU machine.

Somehow it's having trouble removing the kexts that are left over from the dosdude Catalina patcher's Legacy GPU Patch, and that's why kmutil is failing.

@eminemmm I have another set of instructions to try. I'm having trouble figuring out how my previous instructions would not have worked, but try this before I suggest anything more drastic.

First, make sure you've done a Time Machine backup, as I've mentioned in a few previous posts.

Next, try doing the following:

Boot from the patched installer USB. Open Terminal. Then run the following commands:

cd /Volumes
mount -uw "Volume Name" (such as "MY KINGSTON SSD" or "Macintosh HD" or whatever your Big Sur volume is)
cd "Volume Name"
cd System/Library
rm -rf Extensions
rm -rf Extensions.old

Then quit Terminal, start the Installer, and reinstall Big Sur. See if you're able to make WiFi and Ethernet work afterward.

After doing those commands and installing Big Sur , will I try again to apply patch.kexts from USB ?

I tried your commands but ended with same error I guess.

Im so glad alot of you guys already got it up and running smooth with wifi....Its just to many steps to follow for me and my computer skills right now...I cant wait for dosdude to post.....os big sur on an unsupported mac...It should be out any day now i would think?..He lately waits for it come out from apple to the public before creating his utube video on how to install it with a 16gb stick or larger..cant wait for that...

Sorry to break it to you, kid, but dosdude1 most likely isn't making a patcher this year

 

[Alex-Microsmeta]

@Barry K. Nathan If possible, could you add the USB mouse and keyboard support also in the USB BS installer modified with micropatcher, on next releases?

Why wouldnt he?...he always does?..how do you know this?

I don´t think this is a forum for this question. We all are happy to get help from Barry and others. You should take what you can get.If there are questions belonging dosdude you should try to contact himself. As I know he very early told us that it is not his intention to make an approach to a patcher.

Slightly off topic:

Does anyone experience new (inet) connection problems with Safari on BS Beta 10 (and possibly other internal service like spotlight) ?

While Firefox and ping on terminal shows me that there is a working connection to my router and from there to the internet Safari constantly refuses to work. DNS is working, too (nslookup). Disabled WIFI and cable Ethernet one by one and no changes.

Created a new different user account with the same behaviour.

Writing this message from the Big Sur Beta 10 using Firefox. Problem came up after startup this morning (changed router firmware lats night and selected WPA2/WPA3). No changes within Big Sur, not experimental kexts - I promise

EDIT - this is a local problem on this particular machine

if you made any changes to the router, it is no longer the same. Delete all existing wifi connections saved in the system and add them again, I recommend even resetting your router and clearing DNS caches on macOS.

Thanks, I started to look into this. Since I have two running connections (cable and WIFI) and other software like Firefox remains unaffected I ask myself how a (possibly) non working secondary and sometimes even disabled WIFI connection could block the Safari from connecting. Even using the IP of the connected router does not work (while in Firefox).

Even in a newly created account the behaviour remain the same, so it cannot be the account. Just swicthed on another iMac (not used for three days) and this one runs fine with Big Sur B10 and the same router and WIFI and Safari....

don't forget the NVRAM, it loads information from the wifi.

He doesn't have the time anymore. And besides, Big Sur is way different, so he'd have to re-code everything

 

[TimothyR734]

And i read the same on discord with his busy college schedule he doesn't have the time need to work on the patcher as it does need to be built from scratch it would be possible with metal capable GPU's . And getting graphic acceleration on non-metal gpu's might not even be possible for the older Mac's

If we agree all that there will be no @dosdude1 patcher in near future @Barry K. Nathan and/or @jackluke should add some info about the current state of the development to the first post (not that I expect every new user to find it and read it). But we could at least add the GitHub link and something similar to a "support list"? I just added a * to the iMac 12,x which can be upgraded with a Metal GPU and a WiFi/BT4.x ac card, too.

 

[Barry K. Nathan]

I tried your commands but ended with same error I guess.

I'm stumped at how that error could still be happening, but hopefully later this week or sometime this weekend I'll have something else for you to try.

Hello, what is that? Can't install Big Sur with the micropatcher 0.4.4. iMac at the end of 2012.

To properly troubleshoot it, I will need to see the installer log. (I guess I should add instructions to the README about how to save the installer log.)

The quick-and-dirty approach is to just try again with a different USB stick. If a different stick works, then your first stick is broken.

This is the same usb stick with which I already patched the iMac 9.1 of 2009. The mistake is new to me.

It's been known to happen that USB sticks break. Do try another USB stick.

 

[jackluke]

probably Hopper Disassembler can't deal with the ARM instruction set anyway, it may ignore ARM code already while reading the exec file.

I made some searching and noticed that Disassembler can understand till ARMv7 and ARM64 (that is ARMv8) while any recent iOS hardware device and Apple Silicon Mac should use ARMv8.4-A .

Hello. Okey, thank you. I created a new USB stick. But I also exchanged the memory, because I also had problems with Catalina. ( Insallation program data error) Now it worked. Thank you

don't forget the NVRAM, it loads information from the wifi.

At the very end I had to reinstall the Big Sur Beta 10 over this existing installation - this solved this particular Safari problem.

Bright side of all this: I could check the latest micro patcher 0.4.4 with some enhancements I made for the iMac12,x family (but still no H.264 HD3000 iGPU).

EDIT:

Installing the 19H2 patched CoreBrightness.framework breaks Safari on my iMac. While the NightShift is working nicely with the Framework installed I cannot use the Safari to browse any longer This is a really nice one.
This machine is using the iMacPro1,1 ID....
