I used gibMacOS to get the release build of 11.1 and used the Micropatcher to update my 9,2. Worked perfectly. Patched Sur is just a UI for the micropatcher which is super easy anyways.
I am illiterate about coding etc. How did you do that? Can you explain it step by step?

You created USB installer again to install 11.1. Am I right?
Yes, use gibMacOS to get the 11.1, use terminal command to make a USB and then run Barrys tool and then boot from it choosing EFI, then boot from the stick. Install over the top of 11.0.1. and then enjoy all the snappy Safari a person can handle on a Monday. I wouldn't recommend the OCLP route just yet..
Fresh install went perfectly here on mid 2012 rMBP. No glitches at all
I always wanted one of those. That was my dream machine for a long time. I got a unibody later instead.
It's been a good one for 8 years now (if you ignore the new screen and the new logic board
)It'll be my playing around machine once I get an M1.
Oh, but is it even possible to mix and match like that, i.e use OCLP on top of micropatcher-ed 11.0.1 ???
I'm not sure. I know I didn't have very good luck with it on my MBP9,2 and on my MBA5,2 it installed perfectly but borked on OTA to 11.1. I am going to leave Open Core alone for a few versions. I need my machines for the rest of the year to work normal.
Hi! Barry's micropatcher is not needed in this case, you need create install media and perform patch by jackluke USB fixes to get full functional bootable install media. After installation procedures and error sreen, you need apply bigmac's postinstall.sh patch and jackluke's legacy USB fix (need to boot from install media, that you patched early).
Yes, but it requires clearing NVRAM, and using an OC formatted usb drive to boot... if you're not comfortable mounting EFI's I wouldn't recommend it just yet. I did just that however, and installed OC on top of 11.01
so micropatcher does not need to be updated to patch 11.1 properly? You just download the new image, patch it and repeat the initial steps to install? I hope the WiFi fix still works also 😬
That's what I did (but I don't need the wifi patch because I upgraded the wifi/BT card).
Thanks.
That sounds to me like - Don't cross the streams! It would be bad.
Ok, will stick to micropatcher, for now at least.
Come to think of it, I am in no hurry to get to 11.1. Nothing is broken or annoying me at 11.0.1. Will hold off and see how it goes for others.
I did everything you just described and am running 11.1 on a 9,2
thanks sounds good! I will try it again on my external SSD first to see if everything goes as planned before doing it internally. ✊
Y'all talked me into it. 11.1 on my MBA 5,2 using Micropatcher and the latest 11.1 from gibMacos.
the full installer for the RC20C69 is online
Can be downloaded with the MDS tool
Can be downloaded with the MDS tool
Also have a MBP 2012 Retina - still feels extremely powerful to me! Still on Mojave and had no intentions of going to Catalina.
Was a little scared off installing patched Big Sur as there were some reports of graphical glitches - would love to hear more reports of how things are going on a 2012 Retina MBP!
Are the updates 'safe' like an officially support machine, or do we have to stick to patched updates?
Main work machine (Logic Pro - also some Capture One and FCPX) is a 5,1 Mac Pro on Mojave and that won't be getting any updates any time soon.
My rMBP mid-2012, 10,1, i7 quad-core, upgraded 802.11ac is almost identical to Quackers device. The install to 11.1 (20C69) was quick (less than an hour) to my internal SSD. I've been using 11.0.1 for my production now and I can say that everything about Big Sur is impressive. The 11.1 version is even better so far. I have had over 100 tabs in Brave Browser and Safari open at the same time. In addition Photoshop was running with more than a dozen 2-5MB files open, plus GraphicConverter running with several 50-75-file folders open in it's browser windows. Plus put Mail on top of all this.
There are a few qualifiers. Install and use gfxCardStatus; stop displaypolicyd to enable Dynamic Switching and your rMBP will run a lot cooler. Also during prep for installation (I'd recommend using the BarryKN micropatcher v0.5.1 manually) at the install-setvars step employ the -e option for these rMBP with dual GPU's. This is well described in his ReadMe file and I have described the process in earlier posts (search this thread for
sudo install-setvars.sh -e.Lastly, regarding updating. You won't be able to use OTA, but that is not a restriction. It takes only a little more time to download the full installassistant.pkg and make the USB installer for each new update. The new install takes less than an hour. Plus you now own a patched USB installer that you can re-run on top of your existing installation to "freshen" it if you find or note something glitchy. This "repair" is much like we used to do with the combo updaters in MacOS X early days.
As always, put BS on an external disk (I use a super-fast Crucial X8 500GB Portable SSD that comes with a dual USB-C and USB-A plug) first to test it out; and make regular TimeMachine backups.
