Catalina seems so buggy (at least for some folks) on a "supported" Mac, that I can't understand why anyone would want to try it on an UNsupported Mac... !

Why? On this '09 Mini3,1 there are ZERO bugs in Catalina for v.19E287 and all those previous. The Finder is more responsive than El Capitan (the last supported OS) and for the utilization more than adequate in performance with the SSD, 2.53 GHz. CPU and full RAM. Catalina issues are hardware dependent, it seems.

Further update that the dosdude1 1.4.3 patcher is not updating my 10.15.2 MacBookPro 5,1 in either bootable installer or in-place mode. Would love some guidance.

Update that I ran the 1.4.3 patcher and nothing seems to have happened. "About This Mac" still reads version 10.15.2 and I can't tell that any attempt at creating a recovery partition was made.

I'm running an iMac 27" 2011 with the GTX765 with Nicks ROM
install Catalina 10.15.4 with Catalina Patcher 1.4.3
boot screen is black.
if i hit alt i see boot menu and boot fine
with out alt i boot only in black screen

I don't know if it will work, but why would you want Catalina? It has enough issues on supported systems.

How does one get 16 GB to run on an '09 Mini?

 

[ScreenSavers]

Is it pretty safe for me to use the "install to this machine" function to update my 5,1 from 10.15.3 to 10.15.4?

Because once it gets working it works great on my unsupported imac with upgraded metal gpu Thanks to great people in here who made this happen on my 2011 imac which was dead and now back to life.

I guess this is exclusively for vega gpus. On my mac pro (5.1 with an rx580) were slightly worse.

Edit: See End

I've been attempting to install Windows in BootCamp on my 2011 MacBook Pro. Unfortunately, the SuperDrive is broken. I'm using WinClone to clone a drive, but it will not let me because it says SIP is enabled. Obviously it isn't, or Catalina wouldn't be running. I was on 10.15.1, so I downloaded the newest patcher (1.4.3) and the newest version of Catalina (10.15.4) hoping that would fix it.

No dice. csrutil status still reads:
System Integrity Protection status: unknown (Custom Configuration).

Configuration:
Apple Internal: disabled
Kext Signing: disabled
Filesystem Protections: disabled
Debugging Restrictions: disabled
DTrace Restrictions: disabled
NVRAM Protections: disabled
BaseSystem Verification: disabled

This is an unsupported configuration, likely to break in the future and leave your machine in an unknown state.

Obviously, SIP is disabled. But WinClone will not do anything as long as the status is anything other than disabled. Status: Unknown it's interpreting as enabled.

How can I disable SIP where it isn't a custom configuration, to where it's just disabled?

Also, as soon as I upgraded to 10.15.4, I suddenly started getting app crashes on StartUp. 1Password won't start, Word and Excel as well. I haven't tried all apps yet. I can log into another user and launch them. Then when I come back, they work, at least for a while. 1Password, however, I have to do that with every time I boot the machine. I'm going to make a new account and delete this one if I can't get it to stop, but I thought I'd let you know.

But no matter what I do, I cannot get csrutil to simply say "System Integrity Protection status: disabled" and unfortunately, I need it to before this app can clone the image to the BootCamp partition.

Is there anything I can do? Downgrade to Mojave? Does Mojave have the same issue?

Thanks!
Scott

Edit: Well, finally after 3 days, my SuperDrive decides to start working. I'm thinking everything is ok and I start installing. But for some reason Windows thinks the partition is using MBR instead of GUID, and refuses to install because it's on an EFI system and can't use MBR. Well, of course, you need GUID on an EFI system, Windows... and it is GUID... /smdh

I think I've seen everything now. I give up. I'm going to bed.

To disable SIP without a "custom configuration" you should try this attached and these steps, open Catalina terminal:

diskutil mount Preboot
open /Volumes/Preboot/

open your UUID (numbers letters) folder /System/Library/CoreServices/

and replace the boot.efi with this attached

then reboot to a Recovery environment or USB Catalina Patcher, open a recovery terminal and type:

csrutil disable
reboot

Using this and "csrutil disable" should allow this:
System Integrity Protection status: disabled.

the attached is stock from apple build 19E287 .

So with the Working-EFI everything runs "mDP-Working" 4K adapter and FHD adapter
Here automatic backup is selected, which I do not want but macOS-HDD

With the NotWorking-EFI I get a GUI but before login comes the iMac reboots

Without OpenCore I have no picture unless I boot with ALT then I have a picture but the 4K adapter does not work, the FHD adapter works

Under Mojave everything works without OpenCore, but I would like to use Catalina with a 4K mDP adapter and automatically select OpenCore macOS-HDD and not Backup (External)

@Minh_Ton

I think you are the only person who has come close to fixing the Japanese input source on patched Catalina. I have difficulty following what you did, but if you have any additional info on how to fix it – please don't hesitate to post

Did this method work to fix the Japanese input method for anyone? I'm thinking of including it in macOS Patcher.

I recently made a new version of USB OpenCoreAPFSloader2, this is an alternate version to install OpenCoreAPFSloader on an external USB as EFI Boot volume, to store OpenCore configuration directly on the external USB without copying anything on the internal disks.

It can be installed in two ways:

1) Near an USB macOS Installer or USB macOS installation (so you can have a dual booting from apple startup manager)

2) On an empty USB drive (you can use any usb drive in case you need to quickly fix csrutil, amfi, no_compat_check, telemetry plugin and legacy usb kext)


Download here: USBOpenCoreAPFSloader2.app.zip


Moreover this version includes also "telemetrap.kext", developed thanks to @Syncretic (the developer of MouSSE), using telemetrap.kext allows to boot any Penryn Core2Duo while keeping the stock "com.apple.telemetry.plugin" (that since Mojave caused the kernel panic on any Penryn Core2Duo).

@Syncretic made a great work developing a kext upon my request, that eventually can be installed on SLE or /Library/Extensions/ , having it in kextcache prevents (without deleting or replacing) the telemetry plugin loading from xnu kernel.

telemetrap.kext results useful in many situations:

- works both on Mojave and Catalina
- can include it in any custom bootloader
- after any Software Update apple copied again the stock telemetry plugin, don't need more to delete it from single user mode
- can continue an OTA update or an upgrade macOS installer booting directly to the desktop without any kernel panic or bootloop

I assume the telemtrap kext would work on a normal macOS installation? I've renamed it to AAAtelemtrap.kext to make sure it loads as quickly as possible and I'm thinking of including it in macOS Patcher.

Hi!

If somebody really wants to enhance the current (Mojave and Catalina) patcher (Hi @0403979 ) he could probably address the SandyBridge sleep issue which has been solved in this thread and post by @highvoltage12v

All mid iMac 2011 user suffer of this problem to (again and again) manually reinstall kext files from High Sierra to the @dosdude1 patcher installed Mojave or Catalina versions. It would be so nice to have them provided by the patcher, and automatically added to the preselected patches for the iMac12,x systems.

The reward will be eternal honour at least in the iMac (mid 2011) community

post script:
I found out last night the poking around withiin the latest @dosdude1 patcher that these kexts are already there included, it is just a configuration issue and probably some lines of code for the post install pather software to make it work, please.

It works on unpatched installation both Mojave and Catalina, doesn't need to renamed because @Syncretic already developed its exec to load early (as MouSSE.kext), and if notice telemetry.plugin is loaded later (just before loginUI), so you can put it on LE or SLE .

But if you apply a post-install patch to remove telemetry.plugin, after you can also remove telemetrap.kext , because it's more effective when keep the stock telemetry.plugin .

There're quite a lot of different kexts in that post. What new patches would I have to add, minimum, to get it working?

I agree, this is a little bit confusing. Before I make it more complicated I would like you to do this one thing:

Please get into touch with @highvoltage12v , I just made the first contact here. I will ask him to do the same.

He will be able to confirm, describe, and explain this list in more details than I can do:

for this three we found no real workaround

AppleMCCSControl.kext -> /S/L/E
IOSurface.kext -> /S/L/E
AppleGVA.framework -> /S/L/PF

for this following six files we can use OpenCore, but this is an over kill for most users having a stock iMac with AIT 4xxx GPU...

4 files AppleIntelHD3000* -> /S/L/E
2 files AppleIntelSNB* -> /S/L/E

I wrote this down just to come back to your offer, soon. We all waited for this a very long time and created a lot of workarounds, patching patchers, patching patched versions of MacOS, etc...

Thanks for answering!

If you could make a pull request with the needed changes, that'd be much simpler for me!

I wonder if is there a chance, somewhat, to make a patched iso just with the recovery partition, to be burned on a CD, booted from a CD and install it so. macOS Recovery downloads the OS installer and things can get going and patched that way. I am asking this because the USB function of my machine seems broken and I can only install from CD/DVD.

Just make the installer disk on an internal partition?

@Syncretic How'd you fix the telemetry plugin issue on C2D? I've wondered about it for a couple years but never figured out the problem. Do you have code anywhere for your kext?

Hey all, yesterday I updated to 10.15 on my Mac Pro 4,1. Haven't used my cMP in awhile after upgrading my MacBook Pro but I wanted to to take the time to clean up my desktop and get things in order.

The update itself took awhile and I had to convert my drive to APFS because I was coming from High Sierra. When I booted though, the GUI was extremely choppy and stuttery. My card is a Radeon 4870 and listed as compatible but I figured it was because I didn't run the Legacy patch as that card wasn't listed. But I decided to do that and now the system now runs buttery smooth...

BUT... still having some issues. ProRes videos can't play for some reason and have tons of artifacts when playing in QuickTime and the Finder. All other videos play fine.

Figured I try a file in Final Cut Pro. I start it up and edit but after a while the system crashes and logs me out. Very weird and never had this issue before.

Any ideas where to go? Not completely opposed to reinstalling everything from scratch on this drive and starting fresh.

I have a iMac mid 2011 21.5 inch that I upgraded the GPU to a NVIDIA K2100k. I have a i7 2600s 2.8 and 20Gb mem.

I used @dosdude1 patcher to install Catalina. Part of the way through the install (towards the end of the first phase) the screen went blank. The screen stayed blank through the rest of the install.

The voice-over aid began speaking so I know it fully installed, but the screen was still blank.

I ran the post install patches and restarted, still a blank screen.

What am I doing wrong - what should I do differently?
