Seems excessive for no gain. Why not just drop a clean 15.7 on it? You can always try to uninstall safari and reinstall it. Mr Macintosh has a guideyesterday I reinstalled Snow leopard, then El Capitan then Catalina (safari15) on my MacBook Air 2010
im getting this and the ad blOckers don't Blok ads: everything else seem very good, expect my typing sucks.

I deleted everything in /Library/Updates, but the only difference was that SilentKnight needed more time to say I need to reboot (I guess because it downloaded newly entry update). But reboot was fas as usually, with iMac that come up with 19H15 again.... :-(See #14,644. Make sure the OTAupdateFix button is applied immediately after the D/L starts. Since the iMac BootROM is unpatched, some form of OpenCore will be needed to see the macOSInstaller. Attached is a tool to do that. Follow the built-in instructions, closely. ?
This error 71 is most likely due to no EFI partition. You need a USB stick with at least 4GB for macOS to create a EFI partition through erasing command or Disk Utility with GUID enabled. I've mentioned this issue a few pages back.I tried first to install without erasing USB drive, and in second erasing it with OpenCoreAPFSloader (Install on external USB empty device), and at last erasing the drive with DiskUtility.
It's a 16GB Trashend USB stick, and I'm pretty sure it's partitioned with GUID scheme and the EFI partition is there (I used it to install Catalina 19H15 with DosDude1's patcher). EFI partition is not 256MB large, but I'm not aware how to resize it. This is the diskutil output:This error 71 is most likely due to no EFI partition. You need a USB stick with at least 4GB for macOS to create a EFI partition through erasing command or Disk Utility with GUID enabled. I've mentioned this issue a few pages back.
You can use "diskutil list" to check if a EFI partition was successfully created.
/dev/disk2 (external, physical):
#: TYPE NAME SIZE IDENTIFIER
0: GUID_partition_scheme *16.1 GB disk2
1: EFI EFI 209.7 MB disk2s1
2: Apple_HFS OpenCoreAPFSloader3 15.7 GB disk2s2
Can you explain or send a link about this?You can also use OpenCore to disable the AMD GPU.
You might try it the hackintosh way, like this - but that's going to fail if the Intel GPU is disabled by the EFI firmware:Can you explain or send a link about this?
Take a look hereYou might try it the hackintosh way, like this:
https://dortania.github.io/OpenCore-Install-Guide/extras/spoof.html
Or you could apply dosdude1's trick via OpenCore - that would then survive an NVRAM reset, as long as you boot into OpenCore first:
http://dosdude1.com/gpudisable/
I'd recommend the second approach.
Edit:
There already seems to be an OCLP issue that touches your problem:

Edit 2:
But it doesn't explain how to add the dosdude patch using OpenCore.

So you unfortunately can't do it using OC.Can you explain or send a link about this?
Thanks to both. If I can't sell the 2011 MacBook Pro as a replacement parts, sooner or later I'll try it. In past I had already disabled the GPU with DosDude's software method, but then I had to reset the PRAM, and I couldn't disable the GPU again because the display got worse.So you unfortunately can't do it using OC.

I'd suggest you follow K two's suggestion first. Failing that, you can try OCLP to boot your mac. Make sure you use the latest nightly built TUI version. You will need to set SMBIOS to moderate and enable Catalina (in item 5 ->3&7) before building the OCLP (item 1) and write to EFI (item 2, select your USB stick -> EFI). Once you have a working OCLP USB, boot your mac holding the option key and select OCLP EFI (hold down the control key before clicking), then boot to dosdude1 Catalina. You should see OTA update in Software Update. Make sure the OCLP EFI is selected during rebooting for update installation.It's a 16GB Trashend USB stick, and I'm pretty sure it's partitioned with GUID scheme and the EFI partition is there (I used it to install Catalina 19H15 with DosDude1's patcher).

OK, thanks in advice. I guess my fault was to try to install OpenCoreAPFSloader3 using my MacBook Pro. Using iMac it installed on first try (to USB stick with DosDudes patched Catalina Installer). Let's go on...? The @jackluke tools are intended for use with unpatched ROM, non-Metal actual Macs. Let's get back on track. ?
OK, done, done, done... but:The So, once the USB booter is built, correctly. . . . . Do this - Delete everything in the /Library/Updates ƒ, one more time. Open the Software Update C/P, then run CatalinaOTAswufix app by double-clicking on the folder icon (the app runs best from inside the home ƒ e.g. Desktop or Downloads ƒ), The app will open to two(2) options - select the Software Update fix, the D/L will start in the C/P - immediately apply the OTA update fix button, it may ask for p/w, the D/L will complete and the progress bar will run to about 15% and reboot, hold the option key and select the USB drive furthest to the right, the iMac will boot into a menu,
OK, far all the rest, I think I need the above lacking step... Thanks again in any case.MacOS installer will be one of the entries, once selected the installation will complete and restart <option> into Catalina Patcher v.1.4.4 (if accidentally booting into USB boot picker menu, the Catalina Patcher will be one of the selections, it will boot if selected), re-install recommended patches, Force Cache Rebuild to complete. If performed as documented within the apps this works every single time. Run SilentKnight after the update is completed.

I really appreciate your Security Update Beta installs Because of you, I can have confidence the Security Update release is going to work without issue.CatalinaOTAswufix.app, DD1 Catalina Patcher, Open Canopy booter strikes, again. Latest Security Beta runs as intended. Also, two other Apple updates, then MRT took two strokes to update, followed by Validation Patch Update, rebuild kext cache, restart into Build 19H1511. No issues, so far.

Thank you. Finding bugs is a great diversion. See avatar ?I really appreciate your Security Update Beta installs Because of you, I can have confidence the Security Update release is going to work without issue.
Do this - Delete everything in the /Library/Updates ƒ, Open the Software Update C/P, then run CatalinaOTAswufix app by double-clicking on the folder icon READ THE BUILT-IN INSTRUCTIONS (the app runs best from inside the home ƒ e.g. Desktop or Downloads ƒ), The app will open to two(2) options - select the Software Update fix, OK - the D/L will start in the C/P - immediately apply the OTA update fix button, OK. The CatalinaOTAswufix app will confirm the success of each step. The update will complete and re-start to option boot into the DD1 Catalina Patcher. What Catalina build are you running, now and by what means Catalina installed??Newb here. I ran the main.scpt that runs catalinaswubetaotafix.command and it appears to have run successfully, but I still only see this.
