I had success APFS Patcher with my MacBookPro 2009 MBP5,3 ..
EDIT: I tried the APFS Patcher.
1. Step was backup / read out the ROM ... takes at least 7-8 minutes
2. step was writing patched ROM . takes even longer
- i think around 15 Minutes... litte fear comes up
Info: You see, with my SST eeprom "inside" i didnt get displayed some EEPROMs - like for MX.... to select for flashing.
Then success Message:
Reboot worked - but i cant test APFS because i am at HFS+ but i believe the success message.
APFS boot untested because i am on HFS+ SSD.
Could i test patched ROM APFS ready with a APFS (GPT) USB Stick?

macOS 10.16 will be named Big Sur and the UI will be differenti from Catalina... No good news for us.? https://it.m.wikipedia.org/wiki/Big_Sur
If they add SSE4.2 as darwin xnu kernel requirement (current 10.15.6 beta 2 xnu version 19.6.0 with SSE4.1 support) and contextually drop the "kext" (kernel extensions), then it's a trouble for penryn core2duo, but they shouldn't, otherwise there is the challenge for non-metal acceleration.
About the installer I doubt they change its BaseSystem.dmg structure, and should use as post-install still a dual APFS system and data, but maybe they could enforce the AMFI.
About the name, "Big Sur" is plausible, also because has a very similar landscape as Catalina.

how can I do it? I did copy it on a usb key but I couldn't log from it. I have to admit that I'm not very familiar with macOS
. create a usb patcher 16gb you can also download a copy of macOS Catalina then once it is complete reboot your Mac hold the option key and choose the Catalina Patcher is your hdd/ssd your installing Catalina formatted APFS
Also, the fact they apparently will be using a macOS 11 version numbering suggests the hard break with the legacy kernel extensions is here. Even if they leave the ability to run the legacy kernel extensions, I suspect that it will be very difficult to shoehorn back in those from Catalina to allow unsupported machines to run. Probably a bridge too far this time around.
Also another two years of hardware got dropped.

Continuity and Catalina on 2007 iMac 7,1
This project started when I found a 20 inch 2007 iMac in a dumpster. I added some RAM and installed El Capitan and gave it to my iPhone-loving cousin.
The 20 inch iMac was the top model with a 2.4 GHz CPU and a Radeon HD 2600 Pro. Unfortunately the dumpster had scratched the glass. Instead of searching for a replacement glass I bought a 24 inch iMac with a failing GPU for 30 euros. The plan was to swap the good GPU from the 20 inch iMac to the 24 inch iMac.
I first updated the firmware for APFS booting using Dosdude1's APFS ROM Patcher. I also prepared a clean install of El Capitan on an SSD on my Mac Pro. (Unfortunately I forgot to enable remote desktop.)
I had ordered a Core 2 Duo T9300 CPU to enable the Mac to run Catalina. I used some old Arctic Silver 3 on the CPU and the GPU. For the GPU ram I reused the white silicon paste. The GPU on the 24 inch IMac had been running much hotter than in the 20 inch iMac, deteriorating the black rubber foam and leaving sandy black dust inside the Mac.
I had considered just swapping the whole logic board, but once inside I noticed that the 24 inch logic board is larger. The only electronic difference seems to be that there are unused extra pins in the MXM connector in the 24 inch model.
I placed the 120 GB SSD in a plastic 3.5 inch adapter I had ordered from eBay for $15. I moved the thermal sensor to the new drive and used the original fasteners to attach the drive.
The most difficult part in reassembly was attaching the inverter cable to the power supply. I had to unscrew the PSU from the case to get the cable in place, then screw it back in place with one hand. Despite this I failed on the first attempt. When I restarted the iMac the display stayed black. I could hear the boot chime and all four status LEDs lit up. Unfortunately I had not enabled any form of sharing, so the Mac did not show up on my network. After some experimenting I did manage to put the Mac to sleep, so I knew the backlight was the issue. Also LEDs 3 and 4 indicated that the GPU was on and communicating with the LCD.
After removing and reattaching the LCD I got the iMac to boot into El Capitan. As the aluminum bezel was still missing, the WiFi and USB cards were exposed. I tried the BCM94331CD card and adapter I had ordered from AliExpress from my Mac Pro 3,1 for $13.99. Turns out the miniPCIe slot on the iMac has the needed USB connection. (For some reason the adapter in question failed to work on the Mac Pro, preventing the Mac from even booting or chiming. On the iMac it works fine.)
At first the Bluetooth function on BCM94331CD card did not show up on the System Profiler. After I removed the original BT card it showed up. I then ran Continuity Activation Tool on El Capitan to check that everything worked. I had trouble securing the BCM94331CD card as the only screw hole on the adapter was on the wrong side. I ended up securing a bag sealer to the single stud, hoping that the bezel would put additional pressure on the card.
I did a clean install of Catalina using Dosdude1's Catalina patcher. Some minor issues emerged. It was not possible to manually select the patches before the installation. The installer applied the APFS boot patch and the legacy WiFi patch which are unneeded in my system but are part of the default list for the iMac 7,1. Also I ended up without a recovery partition.
On Catalina I tried to run Continuity Activation tool again. The script failed to start. I then followed instructions I found on Reddit: I opened the package contents and ran the included script file directly from the terminal. System Preferences under "General" now shows that "Handoff" is available and activated.
The iMac already had 4 GB of ram. I found El Capitan on a HDD to be extremely sluggish with constant beachballing. Catalina on an SSD seems usable, but it still shows an occasional beachball. My 4-core Mac Pro 3,1 with technology from the same generation works noticeable better. The 4 GB of ram should not be the limiting factor as many modern Macbook Pros and Airs came with 4 GB of non-upgradable ram soldered on. The weakest link may be the GPU. It takes several seconds for all windows to show up after login. Evidently there is still room for upgrades and improvement!

Hi all,
I want to update my Mac Pro 3.1 from 10.15.3 to 10.15.5.
I have download the latest dosdude macOS Catalina Patcher 1.4.4 and created the SUB key as always.
When I reboot the Mac Pro it does not recognize the USB Key but if I try into my iMac 27 2011 the USB work perfectly.
My Mac Pro has the APFS Rom patched.
Any suggestion to solve the USB Key boot in my Mac Pro 3.1?
Thanks

Hi all,
I've installed Catalina on my Macbook4,1 with succes and am very grateful to all the contributors. Thanks!
I have noticed that my Macbook won't go in sleep mode, neither manually nor when closing the lid.
Does any of you have tips how to solve this?

I need help. I’m currently running High Sierra on the original spindle HDD. I want to upgrade the HDD to an SSD and install Catalina using dosdudes’ Patcher. I have two new Samsung SDD’s (256GB 830 Pro and 500GB 860 EVO).
I installed the 256GB SSD (formatted Mac OS Extended (Journaled), GUID Partition Map) and did an in-place installation (Internet Recovery Option while holding Command + R) of High Sierra. On the next reboot I get the "Flashing folder with Question mark". I immediately erased the SSD and tried my steps again but with the same results. So, I thought it must be something with the new 256GB SSD.
I installed the 500GB SSD (formatted Mac OS Extended (Journaled), GUID Partition Map) and did an in-place install of High Sierra and again, at the next reboot I get the "Flashing folder with Question mark".
So, I did an in-place installation (Internet Recovery Option while holding Shift, Command, Option + R) of the original macOS Mountain Lion. On the very next reboot I got the "Flashing folder with Question mark" again.
I put the original HDD back into the MBP and it rebooted with High Sierra without any problems.
I took the 256GB SSD and put it into an external enclosure and plugged it into the MBP. I erased the SDD and formatted it as stated above. I used “Disk Utility” to clone the HDD (High Sierra) onto the SDD. I used the “Startup Disk” preferences to select the SDD on the next reboot. Well, same results, I get the "Flashing folder with Question mark".
So now I’m getting frustrated. I rebooted into High Sierra using the original HDD and formatted the 256GB SSD with APFS file system. I downloaded “dosdudes’s macOS Catalina Patcher” and prepared the bootable USB (formatted Mac OS Extended (Journaled), GUID Partition Map). I followed the Catalina install instruction outlined throughout this thread using the bootable USB but on my first reboot of Catalina, again I get the "Flashing folder with Question mark".
Can anyone tell what else I can try? Apparently, I’m having issues with a complete installation using an SSD.
I checked Apples website: EFI and SMC Firmware Updates for Intel-based Mac Computers (https://support.apple.com/en-in/HT201518) and it has ROM Version: MBP81.0047.2AB (2015-001); SMC Version: 1.68f99. This is different from my specs below:
Model: MacbookPro 8,1 (Late 2011)
Processor: Intel Core I5 2.4 Ghz
Memory 16MB 1333 Mhz DDR3
Boot ROM Version: 87.0.0.0.0

Correct me if I’m wrong, but I don’t think MBP5,1 can use the ROM patcher. Instead, doesn’t it use the alternative APFS boot sequence?
