Hey there, same exact machine as you and same problem after I installed DP2. I suspect it’s the OpenGL patches so I remedied it by disabling reportcrash in the terminal(copy and paste):


launchctl unload -w /System/Library/LaunchAgents/com.apple.ReportCrash.plist

sudo launchctl unload -w /System/Library/LaunchDaemons/com.apple.ReportCrash.Root.plist

Thanks for that. Having the same issue so just disabled ReportCrash.

So I've installed Catalina DP2 on my MacBook Air 4,2 and everything seems to be installed correctly. I'm getting acceleration, wifi, trackpad, the whole nine yards. However, when I look in Activity Monitor I notice that ReportCrash seems to be constantly shooting up to the top of the CPU list and then drops back down. If I open up Console, I see that universalaccessd, PerfPowerServices, and lockoutagent seem to be crashing multiple times per minute. I'm going to assume this has something to do with the patches for acceleration, but I was wondering if this is either a known bug or if I didn't apply something correctly.

I created the installer dosdude1's beta 15 installer, and then used the patches included in the installer during a reboot. Thanks for the help and great work all!

Same issues here on my MBP8,1.

At last, the first preliminary release of the FULL macOS Catalina Patcher is now done! This is definitely one of the best macOS patcher implementations I've ever created, and it works amazingly well! I have not yet implemented all the features I intend to, but they will be coming very soon. As of now, the tool works perfectly with its new user interface, and will allow you to install a fully-patched copy of macOS Catalina on your unsupported system!

The tool is able to run under as old as Mac OS X version 10.6 (Snow Leopard), ensuring maximum compatibility (doesn't use any of that awful Swift rubbish).

As of now, the same prequisites apply as with macOS Catalina PartialPatcher:
  • The system must support booting from APFS volumes natively, or have had native APFS support added to its BootROM via my APFS ROM Patcher tool
  • -no_compat_check must be set in NVRAM to install, as detailed on the webpage.

Let me know how you all like it, and of course, please report any bugs!

This is amazing!

However, I'm still waiting for the APFS patch as I can't ROM patch my Late 2008 Unibody MacBook 5,1 as my System Report - SATA/SATA Express says NVidia MCP79 AHCI

@dosdude1 Respect! The patcher looks great, like Apple itself. Works flawlessly.


Installed on my iMac 24 "Early 2009. Installation without problems, but does not find any hard drive to boot.

I think the problem is that the Mac can not APFS ???

Another success. Installed on my iMac8,1 without problems. No WiFi yet, but I'm sure it's coming.

One suggestion for an enhancement:
When the installation completes, it re-boots immediately. Depending on the hardware, this generates a KP, pending running the post-installation patches. Would it be possible to pause the installation when it has completed and wait for a user confirmation? I was not sure whether the KP was caused by a re-boot or an error on the installer. Otherwise the patcher has the appearance and usability of one of Apple's own products.

Be patient, this patch is pre-release, just like the macOS Catalina, when you get the final version, we will have the patch released like everyone else, and this is something already implemented previously.

I have noticed that starting from Catalina the AirDrop function requires a BT 4.0 (internal or usb dongle) to unlock/discover and be discovered from other Mac or iOS devices in the same wifi network.

However in my 2010 machines internally I have a BT 2.1 , so using only a generic BT 4.0 usb dongle, without patching or installing any IOBluetooth driver, it does work.

I only tested with Broadcom AirPort Wifi 0x14E4, 0x9* (or later).
In few words my original driver was 4331, then whitelisting my boardID I can use the 4360 driver.
Almost surely this method works for Broadcom AirPort from Late 2009 to pre-2012 machines.

Since some Broadcom AirPort Wifi 0x14E4, 0x8* (or earlier) required specific legacy patches (IO80211Family and corecapture.kext by @parrotgeek1 ), don't know I guess if maybe add in the 4360 Info.plist your "PCI match ID" example: <string>pci14e4,4331</string> , maybe could work too.

Instead seems the Atheros Wifi are excluded by apple for continuity or other similar features.

I replaced my BT/WiFi modules in my Macbook Pro 17 late 2011 and Mac Pro with modern modules years ago. Even Continuity works, with thew Continuity Activation Tool.

That's right, I have not been able to install here yet. I'm running out of time to do a backup, but I've got everything ready. I believe that the final version should arrive earlier than expected, as Apple has already released the public beta more than a week in advance.

Ok but on Catalina you don't have this: AirDrop fix "Search for an Older Mac" on Catalina

Instead I fixed that function for:

- patched AirPortBrcm4360 driver (for 2010-2011 machines) to use the stock Catalina IO80211Family*.kext
- machines with upgraded AirPort Broadcom taken from 2012 machines or later
- any Catalina supported Mac

"Continuity Activation Tool" developers, even if developed a great tool, are completely unaware of it.

Careful that Continuity Activation Tool on some Broadcom Wifi cards it patches also the IOBluetoothFamily that in some cases can cause a kernel panic (boot-loop) that on Catalina is not so easy to fix, since you can't "kextcache" from Catalina single user mode. Instead on Mojave was easier fixable.

Anyway upgraded Broadcom AirPort cards produced from 2012 (or later) should be safe to use that Tool.

Hello :)

My language is not English, but I will try my best.


This guy
claims und warns not to use Dosdude1s APFS Rom Patcher with NVIDIA Chipsets.

"Today I show you how to flash the ROM on your unsupported Intel Chipset Mac to allow native APFS booting using dosdude1’s APFS ROM Patcher. (WARNING: DO THIS AT YOUR OWN RISK AND DO NOT TRY NVIDIA CHIPSETS!)"


My Mac mini 3,1 core 2 duo 2.53 ghz has got an Nvidia MCP97 Chipset with a Geforce 9400 256mb graphic card.
So, what can I do about it ? Is he right?

Did somebody of you guys here patch a Mac mini 3,1 as mine? Will it work?
Dosdude1s Catalina patcher tool requieres native APFS boot. Will he change it and add a patch?

Thank you so much

DON'T DO IT!

I have tried @dosdude1 APFS patcher on my Mac mini 2009 and it bricked my maca mini, had to order an EFI chip, and had to go to a local eletronic shop for them to weld it on the board.

It's working fine again but I don't recomend you using it because these mac mini's were launched with several EFI chips and tho I took my mac mini apart to pick the correct one as he warned you that you should check it first, it still didn't work.

Im not complaining or anything, I knew what I was getting into, I'm a huge supporter of his work!

My advise for you is to wait it out, I know it's hard and you want to try it out, but just wait for @dosdude1 to release his patcher with APFS patcher for machines without native APFS, his has done this already in previous patcher's, so Im sure he will release this soon.

Just wait a little longer, that's what I advise

I used the ROM Patcher on both of my Nvidia Chipset Macs (Early 2008 MBP & late 2008 unibody MacBook). I had no problems and it worked perfectly, just make sure your computer is plugged in and charged. Of course YMMV, I’m just sharing my experience with @dosdude1 APFS ROM Patcher.

Yeah, actually, I think the main issue with doing it on MCP79 machines is that it takes SO LONG to flash for some reason. What I think causes bricks is people's systems turn off or go to sleep during the process (as it takes 30+ minutes sometimes). So, chances are, as long as you make 100% sure your system stays running and out of sleep mode during the entire process, it'll work just fine. I can't guarantee this, but that will be the case most likely.

although
sound is perfect
Wifi+bluetooth works perfect
Keyboard and all features work perfectly eg.(Keyboard brightness,Brightness Control and Sound control.

Thanks Everyone for Their Hard work on Succeeding this.

Do you know of a Broadcom AP card that I can purchase off Amazon or eBay that does support Airdrop for a Mac Pro 3,1?

Thanks in advance,

Since apple use proprietary connectors for many of their internal devices differently from Mac to Mac, I don't know exactly which one will fit on your board, but any Broadcom Airport produced after 2010 is good for that, and from what I noticed the SystemReport Wifi ID should be this 14E4, 0x9* or higher.

For example my PCI ID for both 2010 machines are the same (checked from supported HighSierra):
ioreg -r -n ARPT | grep IOName
"IOName" = "pci14e4,4353"
SystemReport: 14E4, 0x93

Anyway many here have upgraded their MP3,1 Broadcom Airport to recent ones, and they are compatible with stock Catalina IO80211Family*.kext.

I managed to install with your patcher Dosdude, so many, many thanks, alls well so far, I was going to install Catalina on a partition on my main HD that has Mojave on as well, it's a 1 TB SSD, but when I looked at it to partition it, only the first aid was enabled, all the others greyed out, and its formatted in Mac OS journaled, I'll leave it for now and maybe when the final Catalina is sent out I will overwrite completely, but for now I cannot thank you enough and if you ever come to Glasgow, would love to treat you to a meal.

Thanks. :)
