macOS 10.15 Catalina on Unsupported Macs

[TimothyR734]

I don't remember the date it was released but someone should edit the first page dev beta 3 is 19A487m

In Mojave, there was a fix to recover the recovery OS. Is that doable in Catalina as well, yet?

I tried it no dice

That's a bummer.

 

[jackluke]

Can I apply this to Mojave?

Yes, or you can apply this: Mojave VolumeIcons for apple boot manager

The script just needed to integrate or to type before running in Catalina Terminal: sudo mount -uw /

However keep in mind that the "CMD+R" associated to your machine is only the latest macOS installed or re-installed or beta updated.

For example, if on internal disk I have two APFS containers with Mojave and Catalina, and I install/update Catalina, then "CMD+R" Recovery is Catalina, if instead I re-install or update Mojave to its next beta then APFS Recovery becomes the Mojave one.

I used your solution for the working APFS recovery from the page 415 of the Mojave thread. So right now I have Mojave/High Sierra installed. Pressing "CMD+R" will take me to the APFS recovery of the partition that I selected as a Startup Disk in a System Preferences. Do you think that something like that can work for Catalina partition as well?

Oh right, I didn't noticed that also selecting from Startup Disk the Recovery was adjusted to the macOS installation, but I guess you have HighSierra in HFS+ , since for APFS container to setting the default Recovery I used typically this: diskutil apfs updatePreboot diskXs1

Try re-downloading a new installer, and also try a different USB drive.

Thank you so much, @dosdude1 Re-downloaded and used a different stick. Worked like a charm. I must say Catalina Beta runs incredibly well in my macbook 8,3 , 17" GPU disabled.

Actually Mojave/High Sierra are both APFS and "CMD+R" will correspond with the APFS Recovery of the partition that is selected as a Startup Disk.

Just finished another update to Catalina Patcher, which now includes an all-new, fully-automated post-install tool! While it can still be applied manually just like older post-install tool versions, this new one will now be applied automatically for you once the Catalina installation completes, with all the optimal patches for your machine pre-determined.

Thank you again!!!! Now I can't wait to have APFS patch on installer to try it on my macmini 4,1 . I will report all issues to help for other users.

 

[Antonidas]

I’m Unable to create a usb installer with dosdudes Catalina patcher as it crashes every time, I’ve tried five different usb sticks all 16g and every time it crashes ?????
Any ideas

Me helped it to retry the process on an second Mac not running the catalina Beta. Maybe try that. If you don't have a second mac just install the latest supported version for your mac and create a partition from it an the try it on there.

Thanks @dosdude1 install on macbook pro 2011 work! I just can not turn off AMD.

is there , or will there be a patch to make pci m2 ssd drives to be recognised as internal.
as at the moment its external with the wrong icon ?

 

[MacPeet]

Is there a new beta out? Your build number ends in "m" whereas mine is the same, but ending in "l". Or is that just public vs. developer beta?

The macOS Catalina Patcher 1.0b4 downloads the 15.0.16 19A487m.
This is the public beta.
After installation in Library/Preferences/com.apple.seeding.plist

SeedProgram = 3 (3 is beta / 2 is seed)

and Library/Preferences/com.apple.SoftwareUpdate.plist

https://swscan.apple.com/content/catalogs/others/index-10.15beta-10.15-10.14-10.13-10.12-10.11-10.10-10.9-mountainlion-lion-snowleopard-leopard.merged-1.sucatalog.gz

So change after installation:

com.apple.seeding.plist to 2

and in the terminal:

sudo softwareupdate --set-catalog https://swscan.apple.com/content/catalogs/others/index-10.15seed-10.15-10.14-10.13-10.12-10.11-10.10-10.9-mountainlion-lion-snowleopard-leopard. merged-1.sucatalog.gz

Now everything's alright.

Are any windows transparent? It seems like you achieved a semi acceleration/some sort of CPU based transparency.

You can install Catalina over it and it should work fine. But make sure to have a backup just in case.

Unfortunately I'm on HFS+ and it support APFS only

Thanks @dosdude1 install on macbook pro 2011 work! I just can not turn off AMD.

As I said before, works very very well with that GPU disabled.

Is there any problem if I leave the public beta numbers?

Thanks

 

[MacPeet]

No
Settings with SeedProgram=3 shows in updates only the next puplic beta
Settings with SeedProgram=2 shows in updates the next DevBeta

OK @******* thanks, but how to disable AMD?

 

[Antonidas]

That's a bummer.

Just make an Recovery USB with the latest supported macOS Version for your mac and use this as your recovery-partition. Thats how i a least was able to recover snapshots or backups

 

[ASentientBot]

As of DP2/PB1, it seems that two processes are constantly crashing, causing poor system performance. To disable those processes, run the following commands in Terminal (ignore //AppleInternal... error), then reboot the system:

sudo mount -uw /
sudo rm /System/Library/LaunchAgents/com.apple.universalaccessd.plist
sudo rm /System/Library/LaunchDaemons/com.apple.PerfPowerServices.plist

Wait... what? On my machine, these used to crash with the earlier versions of my wrappers, but after making some modifications to my code, they no longer do. Are you sure your patcher includes the most recent versions?

I'll attach them here for convenience.

If you are still getting crashes, please send me the logs. My DiagnosticReports folder doesn't have any new .crash files (other than Photoshop) since over a week ago. I didn't realize you guys were still seeing this level of instability with my fixes and I'd like to fix that if possible.

You can do it by software, just to try, but if you reset the ram , it will appear the AMD again.

I have it disabled by hardware, with the first method of @dosdude1

But the best and present method by… of course, by @dosdude1 , is the Demux., The best one.

Oh, really? I thought I was using your latest ones... Maybe not. I'll have to check and make sure.

 

[DragenFi]

@DragenFi here is a script I wrote for easily applying the Mojave day/night Volume icon for apple startup manager, I also included the possibility to return to the default volume icon.

The script is totally safe and harmless for any machine.

While the apple stock "Mojave icns" didn't worked (previously uploaded), instead these icons that I manually modified/patched will work properly as VolumeIcons.

Thanks for doing this, very much appreciated!

I confirm, I have no crashes on those universalaccessd and PerfPowerServices since you already fixed a couple of weeks ago.

This got nothing to do with the patcher.
It’s been like this since I can remember and it’s the same on supported machines . If it does bother you for cosmetic reasons, simply change the icon of the drive.

1. Select the drive
2. Press cmd + i
3. Drag one of your internal drives (with the desired icon) onto the symbol in the upper left, next to the name of your m2 drive
3. The symbol should now be the same as your internal drives. To undo it, just select the symbol inside the info menu (cmd + i) and press backspace
