macOS 10.15 Catalina on Unsupported Macs

Could it be that the screen time needs Metal to overlay its UX? Anyone with a Macmini5,1 (or similar) and screen time blocking working?
You'd need to replace, from a working Catalina unsupported Mac installation (possibly taking it from a MBP8,1 or similar machine), the /Volumes/Catalina/System/Library/Prelinkedkernels/prelinkedkernel onto the /Volumes/USBInstaller/System/Library/Prelinkedkernels/
This should re-enable the Wifi driver in a Recovery Environment, if you boot it in verbose mode you can clearly notice that "ARPT and IO80211" are parsed from the recovery/installer kernel.
If after that you can't reach more the Recovery/Installer GUI, then simple double-copy the USBInstaller immutablekernel and rename it as prelinkedkernel, or take the prelinkedkernel from the /USBInstaller/"Install macOS Catalina.app"/Contents/SharedSupport/BaseSystem.dmg/System/Library/PrelinkedKernels/
edit:
This re-use of a system generated prelinkedkernel almost surely works with a stock Catalina BaseSystem.dmg (about 500 MB) , when instead a patched BaseSystem.dmg (higher than 500 MB) is used it might not work.

Quote to me for me.... lol
just a update: the problem is I made the USB installer in other Mac (MacBookPro6,1) and I use a MacBookPro8,1. I forgot to disable “Auto-apply Post Install Patches” 🤦🏻♂️
That’s it...
Hmm... since I managed to kill my Catalina Installation on my MBP5,3 by enabling FileVault (didn't boot anymore after encryption) I have decided to do a clean install and then restore my TimeMachine backup...
Which brings me to asking for help/input:
When I try a System Restore from the USB Key I have created with dosdude1's Patcher 1.2.0, after choosing a backup, I receive a message that my Mac doesn't support APFS booting natively and I can only do a clean install -> which I did because I assumed that using Migration Assistant would be also an option. Unfortunately the Assistant doesn't show any backups (even though System Restore sees them) although it finds the correct disk.

I noticed on MacBook Pro 7.1 the font is pixelated, bad quality, the text is not clear, what's wrong?
You could restart after the error and boot into Macintosh HD (or however you named your system partition) and see what happened. Installation may continue, sometimes it happens.
Ok Thank you....but if i use on mojave bluestacks for example i can add in preferences 4 core...in task manager i was see core in actions.....and now only two....
This is true, if you inject in an OSX Installer/Recovery the GPU drivers the environment is more reactive, once (earlier OSX) I was able also to load the Audio from a recovery, you could make your own attempts trying to generate a prelinkedkernel from a working Catalina setup and re-use it in the OSX Installer /System/Library/PrelinkedKernels/
But sometimes if you put too many kext inside the prelinkedkernel the Installer/Recovery becomes slower to boot (from 3 to 5 minutes or even more) and in some cases might not reach the GUI Mode because of a mismatch between the prelinkedkernel's kext and the ones inside the BaseSystem.dmg preloaded in RAMdisk.
Excellent! Everything works now... well I mean until I tried to use the bluesky patch for light mode and now my MacBook won’t boot into macOS. Any ideas what I did wrong? I just ran the script in terminal selected my main drive.Only installed the bluesky patch and my computer froze on restart.
Make a clean install of the new installer (supplemental 10.15.0), then in the initial settings you can choose to restore your Time Machine backup. If it is not possible, you will have to manually copy the folders, it has no secret, and sometimes the system gets even better after copying each application manually.
I spoke too soon.
The backlight on my A1261 still isn't working correctly. The issue I'm facing is as such (in reference to the F1/F2 brightness settings):
0 bars = backlight off
1 bar = very dim backlight
2 bars and above = dim backlight (no change in brightness between bars)
I've tried disabling "automatically adjust brightness", no avail.
Of course, the keyboard backlight doesn't work either, but I think that's a known issue.
Any help would be much appreciated. Thanks.
EDIT: Looks like this has something to do with the display being CCFL-based? Here's a post about it from @Larsvonhier, and here's a patch for it for Mojave by @dosdude1.

In your case using a BT 4.0 usb dongle might work on Mojave but on Catalina not sure, even if I guess to pair with that card "0x8D" could be requested in addition some whitelisting of this kext "IOBluetoothFamily" inside which I can notice some Mac-IDs , so maybe replacing with yours Mac-ID, but also a wrongly patched IOBluetooth kext can cause kp.

As @TimothyR734 often suggested, re-applying the "Video Patch" from Post-Install can fix that.
Now that I finally had some free time, I finally tested @jackluke's patch of HIToolbox from post #5,573, and it works perfectly. Thanks! I think I'm going to stay on this version of macOS until 15.1 is released and working perfectly on people's devices.

One quick question: What does the SkyLight patch do? I didn't install the SkyLight patch after reinstalling my OS, I just replaced the HIToolbox with the patched one, and yet the transparency issues are fixed. I would like to know if I should still try to install it, and knowing what it actually does would help.
Edit: I just noticed that while most of the transparency issues are gone, the Finder sidebar still has transparency issues. I guess that's what SkyLight does.

So I was able to install Catalina just fine on a MacBook Pro 5,1 but when I try to install the BlueSky patches the system breaks. Applications (and most cli commands) refuse to launch, and the system can't be rebooted. When doing a hard reset the system then won't boot back up and a reinstall in necessary. Not sure if I should try a third time...
Yes, run the backlight CCFL patch that dosdude1 put together for 10.14.2 back then. It still works on the non-LED-based MacBooks like MBP4,1 on latest Mojave and Catalina.
What version of macOS Catalina are you running as BlueSky1.4.4 only works with macOS Catalina 10.15.0+ and when using the terminal you have to have root permissions sudo su

Hi,
A stupid question : my MP 3,1 has no Wifi card but is connected by ethernet to a "box" which is connected to a Wifi router.
Is it possible, with such a configuration, to allow airdrop ?
Serviteur,

Serviteur,
As far as macOS is concerned that is a wired connection, so the answer would be 'no'.
It worked! Notably, I had to remount / as writable (`sudo mount -uw /; killall Finder`) before the script functioned properly.
Unfortunately, I'm now facing another issue: every time I turn "Automatically adjust brightness" off, it automatically turns itself back on a few moments later. This wouldn't be as much of a problem if my MacBook didn't constantly think it was in the dark, causing it to dim the display.
Don't know since these patches are available only for certain Broadcom Wifi cards, from my tests all those starting from 0x14E4, 0x9* or higher (0xA*, 0xB*, 0xC*, 0xD*, 0xE*, 0xF* and so on).
The Atheros wifi cards and Broadcom 0x14E4, 0x8* (or lower) cannot enable AirDrop in Catalina (or at least I don't know how).
@dosdude1 might consider (or improve) the @oliveira131 script (that honestly I haven't tested yet, a bit of perplexity about script when handling board-ID with "short strings" and replacing only one instance not covering other functions inside the driver):
macOS 10.15 Catalina on Unsupported Macs
Hello everyone, I made this shell script to patch AirDrop more easily. This script made the changes, detecting and inputing the board-id in respective kexts.
forums.macrumors.com
Surely AirDrop is based on the AirPort Extreme apple wifi cards, but there was an old script that claimed to enable it over ethernet (under the same router):
defaults write com.apple.NetworkBrowser BrowseAllInterfaces 1 && killall Finder
I guess it could work on Mojave, but I really doubt it will work on Catalina.
