Has anyone tried to install Monterery or Big Sur on a 2012 MacBook Pro non-retina ?

Yep. First Big Sur for a couple of months, now Monterey. Flawless. N.B.: Monterey needs post-install patches on your MBP.

Does anyone know how to uninstall the SIP Disabler Patch ? I booted from a Catalina install USB stick, reinstalled all the usual patches except the SIP Disabler Patch, forced rebuild of caches and rebooted. After reboot, "Patch Updater" said the SIP Disabler Patch was still installed?

Is there a way to remove the SIP Disabler Patch (without reinstalling maCOS) ?

You cannot enable SIP and using a patched unsupported macOS at the same time.

But you may upgrade your GPU to a metal one (iMac11,1) and using OCLP you can have Catalina running with SIP enabled (because no patches are applied to the files system).

Look at the plist for the list of installed patches. Maybe it's not actually installed anymore? Maybe try to find how it was installed. Then you can see if it's installed.
#17,966
#19,687
But I think you need SIP Disabler Patch unless your Mac is now supported? Or you want to switch to OpenCore?

I'm leaving mine on 11.6.1 for now. Works so much better than Catalina.

OK, thanks. That makes sense – I was worried that enabling SIP would cause problems.

My main problem is that I can't add AppleScript applets to Automation permissions. I've read elsewhere that SIP needs to be enabled to enable updates to Automation permissions. I'm only having this problem in the Catalina patched iMac. The Mojave patched MacBook is fine.

Cheers.

Hi all,
I'm trying to make installer on a USB (on mac mini 2011, to install it on the same).
I got strange error when installer starts "An error occurred while restoring BaseSystem.dmg. Ensure that your target installer volume is formatted as "macOS Extended (Journaled)" (HFS+), then try running the tool again." but mu USB (brend new) was just forrmatted on macOS Extended (Journaled)?!

Log file says:
Validating target...done;
Validating source...done;
Could not unmount volume "/Volumes/cat" (Operation timed out)

Can anyone have similar experience and hot how to solve it?

Just a guess: GUID Partition Table instead of MBR?

Operation timed out usually means you have a slow flash drive and it simply didn't complete in time. What model Flash Drive are you using?

Thanks a lot to all of you.

Re: Impossible install security updates after clean Install Catalina (19H2).

Hello all,
After clean Catalina install, impossible to install successfully security updates using as per instructions with CatalinaOTAfix as has been possible in prior install of Catalina (I had Big Sur but decided to revert back to Catalina). I get a continuous "loop" of what seems a successful install process of 005, 007, 008 security updates but when checking OS version update still remains 19H2. In System Report/Software/Installations I see the series of security installions I have executed. I have also tried installs in Safe Mode, wiping out the old system security database, cache clearing through terminal mode and reindexing spotlight and relaunching dock (both through terminal ) but no luck. Does any one have suggestions?

 

[haralds]

I just switched from DosDude patched on MacBook Air 4,1 to trying OpenCore. I do not see the security update.
Is there a flag change required?
I also tried the updater, but it indicated an ineligible system.

A couple of quick delta updates courtesy of CatalinaOTAswufix, OC, @dosdude1 Catalina Patcher v.1.4.4 both in less than 30 minutes incl. post install patches and Force Cache Rebuild. Both also required MRT and Validation Patch updates. Build 19H1615 is now the release version and runs as expected without issues.

Not impssible. Go to Library/Updates ƒ and delete everything in the folder and run CatalinaOTAfix, again. Make certain the OTA update fix button is applied early in the D/L. Install SU-008 as it contains all previous updates and is the release version.

A REMINDER - from the Scriptures according to Dortania: https://github.com/dortania/OpenCore-Legacy-Patcher See Note 2: Currently OpenCore Legacy Patcher officially supports patching to run macOS Big Sur and Monterey installs. For older OSes, OpenCore may function however support is currently not provided from Dortania.

For macOS Mojave and Catalina support, we recommend the use of dosdude1's patchers 👀

I have not been able to get CatalinaOTAswufix to work. Which instructions did you follow?
--> Moving it to the desktop and persisting a few times seems to have fixed it.
--> Rebooting first failed after reapplying patches. Tried directly with boot-args and sip disabled, then with OC. Same issues, it stalled for many hours on 80% progress.
--> Booted back into USB Recovery and did a second patch without SIP manager and WIFI patch (I have an updated card.
--> Now it works. I applied an additional patch for my WiFi card to enable continuity and am running without OC.
--> nvram boot-args="-no_compat_check" (likely not needed, since plist is patched, might enable Recovery, not yet tested)
--> csrutil enable --without kext

Looks solid.

--> Some apps like Parallels and Xcode appear to need SIP totally disabled.

I used to have an application that patched and updated the Recovery Partition so you could use it with a DosDude patched Installation. When rejiggering all my servers to a single Synology NAS I must have deleted it.
Could somebody provide a pointer?

The instructions are built-in and very succinct, follow them closely. There appears to be a learning curve involved? See #14,965 if previouly failed.

every time.

Hi K two,
Thanks for the tip. However that did not resolve the problem as it still shows 008 security update available after executing the OTAswfix aprox. 3-10% download as recommended. Strange... Tried reinstall a second time but result remains the same. What would you suggest?

just updated my MacBook Pro 8,2 to 008. did you select the 'rebuild caches' option after performing the post-installation patches?

Hi Icubed
Once the update 008 installed I reboot to Catalina and patcher (1.44) never pops -up to ask reinstall of library validation, night shift, backlight as it usually does after update. That is , in my opinion because the system remains at 19H2 as if the 008 never happened.

 

[Demontager]

Got MBP 17 late 2011(8.3) with amd 6750m+Intel hd 3000 gpus. I plan to install Catalina. Few questions:
1. After disabling amd gpu in nvram is it possible to get it back? In case i wish to playgames/revert to highsierra etc.
2. Does full acceleration work in Catalina on intel hd 3000 ?

Reboot into the patcher USB not Catalina. Leave the Software Update CP untouched during the installation, does the macOS progress screen appear during the upgrade? Has NVRAM been reset? BootROM version?

my sequence
1) OTAswfix ==> select OTA option
2) start the 008 install
3) let it reboot
4) OTAswfix ==> select OTA option
5) start the 008 install
6) when it reboots, hold option key and select the USB built using the dosdude1 patcher
7) install the post install patches with Legacy Platform Compatibility Patch added
8) near the end, the 'force cache rebuild' checkbox becomes available. select that , then click reboot.

there's probably some extra steps in here, but worked for me.
