Not sure if this makes a sense, but.. FYI (only) my laptop with Nvidia GeForce GT 520M is also unable to reach LoginUI when booting 10.15 Dev Beta 1; but stuck on those blackscreen with console logs. Previously on 10.14.x was able to; using CoreDisplay binary from early build but now isn't. This Fermi is non-Metal capable GFX though SLE has vanilla NVDAGF100Hal.kext. Replacing diff CoreDisplay would result in missing symbol as @pkouame has said. Can not touch my other laptop with Intel HD3000 for testing bcoz it' s currently not in my hand hmmb..
No actual progress, but here are some potentially useful debugging options:
nvram boot-args=kextlog=0xfff
This logs to dmesg each kext that is loaded, plus info about classes defined in them. It's also colorful!
sudo sysctl kern.msgbuf=1000000
Run this from the single-user mode prompt to increase the dmesg buffer by a couple orders of magnitude (larger sizes cause an error, though). This value doesn't seem to be saved across reboots.
export DYLD_PRINT_LIBRARIES=1
export DYLD_PRINT_TO_FILE=/path/to/log.txt
Logs every library that is loaded. Run from a single-user prompt and then exit.
fs_usage > /path/to/log.txt &
Logs every filesystem operation. Run from a single-user prompt and then exit.
I'm also investigating some other debug features I've seen when disassembling binaries, like the iosurface_debug boot-arg. Information is always good!

Please, this is not about character, or lack of. Julian certainly has skills and is quite capable on his own, and by that I mean if he didn't, he would not have received the gift of the 4,1 for further exploration, and resolution by two of the heavyweights on this thread, but ask yourself. Do you know any young generals or presidents, and why not? Only by the accumulation of knowledge, practical application and sheer years of being immersed in every aspect and approach. Countless hours of sheer interaction, bouncing ideas off with your peers, being teachable and pushed to consider other lines of thought by your mentors do you gain perspective, respect, creativity which is crucial to problem solving, and more. Only by these processes do you gain the most valuable of all character assets...wisdom. Julian is young lion, quite capable, talented, hungry and I admire his fearless attitude. He just hasn't lived long enough to accumulate these tools yet and that's not his fault. You have to admit he's not afraid of taking responsibility, and I have watched him be teachable. Those are the two character assets that will insure success in whatever he sets his mind to, and I have mad respect for that. The real point of all this is, obtaining our mutual goal of putting Catalina (10.15) on unsupported macs as effectively and quickly as possible, and learning, so we'll have the tools to do the next challenge. It's about improving the quality of life for those who cannot afford, or who have paid thousands or tens of thousands of dollars to Apple only to have them leave us behind. Please, let's be kind and encouraging, because the example of the team I mentioned previously is proof of that road to wisdom in action. Now all we need is the dude
. Please excuse me for temporally hindering this goal, but it needed to said now, and this is the last I will speak of it. Thank you.
As @jackluke and I both found, you can replace IO80211Family.kext from Mojave or High Sierra to get wifi working.
I highly doubt amd 5xxx and 6xxx series will get accelaration working.
But maybe it work this time...
2011 mbp you can however disable amd graphics and use intel hd3000 graphics, which could work..
Quite possible that an "underutilized" GT 330M is less performant than the Intel.
While you and @ASentientBot are solving World Peace
, my test machine is down and I can't really contribute expect for my habitual Hopper based reverse-engineering. So here's another finding from the new frameworks: the Catalina OpenGL actually looks pretty close to the .3 (aka "stable as a rock") OpenGL. And I am comparing the .3, .4 , .5 and Catalina code bases. The reason is as yet unknown, but this may bode well for future acceleration and compatibility...[doublepost=1559754834][/doublepost]
Very nice job!

Yes, I guess I have been misunderstood, of course Nvidia GT is more powerful, I meant only in that special circumstance when I manually switched among the two GPUs, lets say the IntelHD framebuffer video behaves better then GT 330M framebuffer, but of course only in that case, otherwise no contest.
As I wrote probably in my particular configuration it is semi-accelerated, since I remember when in the early Mojave betas, @Badruzeus showed us that IntelHD Graphics OpenGL kext from Sierra worked on a full Metal-declared-Mojave.
So lets say IntelHDs were the first GPUs that worked on Mojave without so much effort, where instead Nvidia Tesla and ATI/AMD required patching from @ASentientBot and @dosdude1 .
I think APFS is required after high sierra . I downloaded Catalina one from Dosdude's link . First error in log was APFS ... Disk management Software ran and said file system cannot instalAFPS on disk.. Problem it already has APFS .. I have one disk left that has HFS maybe it may work on there but all of my disks are grayed out and say not installable on this machine ....

further info ..The drive i tried to install on is on an Apricorn PCI card and a standard SSD .. Now there is a tought, a M.2 card I am using a Radeon RX570 .. Fun fact the GT 120 from Apple was not good for installs but worked after installs fine and said it was metal

I don't know what the context of this discussion was about but I do hope we can all get back to fruitful collaboration. I may not have been active in the Unsupported Mac Community since Sierra but having overseen a lot of work for OS X 10.8-10.11 patches, I know from experience that any sort of confrontation between developers is just not very helpful, slows down our progress, and most importantly pushes people away from the community. Everyone wants to be a leader, put work into a project, and to be credited for something but please remember to treat everyone with the upmost respect and equality. Because at the end of the day, we're all just trying to save money, right?
what files do you need to patch and how do you patch them. I am very new to installing unsupported builds of Mac OS
I still have my Macmini 2010 (Macmini 4.1) perfectly working with macOS 10.14.5 Mojave, thanks to the genial @dosdude1 patches and it seems that hardware requisites for macOS 10.15 Catalina are the same for my almost 10 years old mac. I'm ready to provide infos as betatester for this mac, and report bugs for every build during full Catalina life cycle starting from beta1, to support all patches developments :-D
Agreed and no misunderstanding, I got you. You mentioned semi-acceleration, I did not see any accelerated "effects" on the screenshots. Just curious.
I have a mid 2010 Macbook running Mojave that I'm willing to use for this project if anyone needs me to test anything for them
I have a mid 2010 17” available for testing purposes, as well as a 2009 13”.

[doublepost=1559766098][/doublepost]I've a 2009 cMP available for testing any portion of this project. Also 08 cMP, thanks @dosdude1....
why is that a problem? All my Macs have their OS installed on a different partition that’s not even listed on Finder and it works perfectly.
What
what difference will it make if the problem is insufficient memory and processor power? I’m not talking about boot up speed, but advanced excel dashboards and heavy math calculations.
why is everyone writing down their hardware? Lets keep this thread clean from beggars and focus on tech talk, how to get cathalina running.
BTW: if a dev needs someone for testing purpose, they choose someone in close proximity to themselves or someone with skills in debugging...
