macOS 10.15 Catalina on Unsupported Macs

[Mr. Anonymous]

hi nt some help about installing mac0S 10.15 macbookpro8.1? there a patch or sun truce for ative hard drive

There is no installer/patcher available at moment.
@dosdude1 is working on it will released soon I think.

You have to modify OS Catalina dmg yourself.
and replace framework and kext's.
Instructions are post in this forum

Why i can't install eventhough i put this command: sudo nvram boot-args="no_compat_check"....it doesn't let me choose where to install...

I followed this: https://www.insanelymac.com/forum/t...macos-installer-app-for-unsupported-machines/

or wait what @dosdude1 just said

 

[arqueox]

Installer patch is coming, please just wait.

i know. I was just experimenting. Someone said it was fully supported without a patched installer.... but i'll wait for yours. Thnx, by the way.

Installer patch is coming, please just wait.

thank you plz send my patche

No rush since you're still working on it, but at some point would you mind describing how you did this?

I sort of started investigating the patch-free method I suggested in a PM to you a few days ago, but haven't had much success. So I'm very happy to hear that you've figured this out!

Oh yeah, I'll explain everything I did once I'm done LOL. I've patched out like 7 checks at this point, and it's STILL not 100% working.

 

[jackluke]

Would you be able to expand a bit on that?
So I do have BaseSystem.dmg and InstallESD.dmg(6.5GB altogether).

- Mount the Catalina BaseSystem.dmg take the "Install macOS 10.15 Beta.app" and copy it on your desktop

- unmount the Catalina BaseSystem.dmg

- From your desktop select the beta.app/Contents/

- inside Contents create a folder "SharedSupport"

- inside this folder drag and drop your Catalina InstallESD.dmg, the Catalina BaseSystem.dmg and these files I attached.

In this way you should have manually rebuild a Catalina Installer for supported Mac without re-downloading the full Beta.app (6,5 Gb).

Questions:
1. Battery sux?
2. Apple doesn’t share anything with Android or any other systems
3. Expensive and worthless
4. They ****ing permanently disable your Apple ID without telling you why, even with a hundred bucks left in the account!

Answers:
1. I have an iPhone 7 for over 2 years. No battery issues. I also have an Apple branded battery case and together I get over 48 hours of battery life still today.
2. AppleTV I believe is being shared on other Systems. And with SwiftUI don't be surprised if Apple goes after a larger market. The base Swift language can run on Android and Windows 10 not just on Ubuntu Linux and Apple's products. What is missing is a common framework. SwiftUI could be just the beginning.
3. Anything good isn't cheap. Apple's products last a long time. Take a look at this thread, the oldest Machines are from 2008.
4. Who leaves unused cash on an Apple ID account? You must be a Rich Apple Customer also known as RAC!

We are almost there guys (installing on a MacBookPro8,3)!!! I know this won't complete successfully, but once I get all these checks patched out, we should be good to go!

I feel a Kenny Rogers song coming on... The Gambler!
[doublepost=1560645086][/doublepost]Btw, I think I found a good simple way to restoring bootable APFS volumes on different size drives. Doing some experiments. I'd be farther along, just this head cold is killing me and my dog, Cookie, has pink eye. She's sitting in my chair while I am still sitting in it. And this really isn't my chair, it's one she's torn apart so it ain't that comfy. lol
---
I'm also running some patches on MP3,1 on different fresh installs and see how they do with the timeout problem and see if they take the ASentientBot's patch or not.

 

[meowdude]

dude these simulators are cooking my laptop lol

also Xcode is mega stable with the patch, works just like its indented.... now SwiftUI is something i’m gonna let cook because it’s really buggy

thanks again @ASentientBot

*sizzle*

 

[TimothyR734]

seven checks patched 133 to go

 

[Starplayr]

I backed up a bootable Catalina installed drive to a disk image to an old SATA Hard Drive in just 2m 4.584s, 13.5GB total that is pretty fast considering it was writing to a hard drive not an SSD and it seems faster than dd too.

Will test a restore next.

Keep that in your lap, and you'll never have children.
[doublepost=1560648254][/doublepost]Backed up a clean install to a standard slow as dirt hard drive in 1m 49.498s. Compressed image down to 10.58GB Disk Savings: 97.9%.

Time to do a restore and see how that does.

haha when I do something that intense on my cpu id typically throw it into clamshell mode and let it sit there while it processes

 

[Starplayr]

With some work got restoring a Catalina install to a different size disk:

Mac-Pro ~ % sudo asr restore --source /Volumes/Space/Catalina/500GB.dmg --target /dev/disk13s2 --erase

    Validating target...done
    Validating source...done

    Erase contents of /dev/disk13s2 ()? [ny]: y
    Repartitioning target device...done
    Retrieving scan information...done
    Validating sizes...nx_kernel_mount:1387: : checkpoint search: largest xid 20577, best xid 20577 @ 273

done

Restoring  ....10....

I will be writing a GUI for it to make it easier backup and restore bootable disks that are in HFS+ or APFS format. There are a few other steps involved.

IOHIDFamily.kext is only needed to fix the delay on Catalina booting, I guess Mac 2011 (Sandy Bridge) are not affected by this, how much it takes to boot your Catalina ? If less than a minute then you don't need it.
[doublepost=1560621178][/doublepost]

These many "apfs_spec_read_wrapper" are related to 32bit coding still present on old frameworks, but they're not severe and don't comprise the Catalina working.

For which other kext/framework you may need check: here

I'm so confused, where did this children/wives/girlfriends discussion come from in the first place? lol

I mean people joke that my MacBook is my girlfriend, so it's sort of relevant for me. But still, what?

on the topic of burns ourselves and how keeping a hot laptop will possibly kill off kids

Do you mean the boost errors? Happens often - boost is a huge C++ library and errors ripple through fast. What are you trying to do?

@ASentientBot

I tested my Mac Pro 3,1 script on a clean install of Catalina.

This one has your stall fix, and I added telemetry from High Sierra, along with WiFi and Sound.

On a clean install there are no hiccups or stalls, and it locates the country you are from, it usually does not give this. But happy to report its clean.

I did notice, if I run some patches from Dosdude1's Mojave arrow updater, it seems to bring back the stalls and timeouts. I know this tool wasn't meant for Catalina, so users be warned.

But if I stick to my shell script only, and do all my updated patches through it, my system is golden.

For me: It still doesn't auto switch to the proper time zone, it knows what time zone you are in, but you have to unlock it, unselect the auto time zone check box, move Apple's selection to back to your time zone, even though the OS has already pinned it correctly.

I am adding the Webcam patch and to those who may be interested in a Mac Pro 3,1 patch, let mew know and I'll post an updated version.

Why the need for telemetry from High Sierra?
My 3,1's running well without it.

- unmount the Catalina BaseSystem.dmg

Absolute Champion! Installing on a supported machine, 7 min to go. I actually restored BaseSystem.dmg to a 16GB partition on a hard drive and then followed the rest of your instructions. Thanks for those extra missing files! I knew I am missing something.

P.S. The only reason I am doing this is because I am dealing with a limited data.

Not only, as for I did for HighSierra/Mojave I've done my usual non-clever test, and also in Catalina the only required UserEventPlugin to boot and work is com.apple.remoted.plugin

All the other 44 are (almost) unuseful, however I don't think that replacing com.apple.telemetry.plugin is so bad, it's just to keep a more complete structure and at the same time is funny that the HighSierra one doesn't send in kp the C2D (penryn) starting from Mojave.

Another note, inside a Catalina BaseSystem.dmg (as the others OSX BaseSystem) UserEventPlugins there is no telemetry, but there is the remoted plugin.

@jackluke,
• Is your Dashboard bringback on Catalina can install -as it should in previous OSes with animation- new widgets? (aside from those native ones)
• Sidecar any further news about working on our unsupported macs? -did you play with it?
• Catalina Notes, could resize manually columns and rows? (Fixed in previous Oses)
