[USER = 1133911] [USER = 1133911] [USER = 1133911] @jackluke [/ USER] [/ USER] [/ USER] ... seit wir den 10.15.3 DP3 (19D75a) installiert haben, können wir die endgültige Version 19D76 überspringen? Dann können wir doch auf die nächsten 10.15.4 DP1 updaten oder?

wer kümmert sich oder wer braucht es:
10.15.3 Kombinationsaktualisierung

Not me. I keep getting the same error message, that the "Patcher" file needs to be updated.

So, I just went ahead and installed the OS 10.15.3 update, ie, not the full installer. Took some time, but it's done. I did just download the OS 10.15.3 Combo Updater file, and maybe that is what I should have done in the first place.

I'll apply the Combo Updater on my Mac Book Air.

1. Put the Catalina Automount in /Library/LaunchDaemons folder reboot
2. run the swupatch in the terminal enter your password when prompted then open up the software update in System preferences download 10.15.3 Final

3. run the catalinaswufix in there terminal before you restart to install 10.15.3 if you have a macOS Catalina patcher 1.3.0. that you used to install macOS Catalina 10.15.2 then run the post install patches with that it works

the correct way to update from 10.15.2 to 10.15.3, is to create a brand new patcher that will download v10.15.3? OR can I do an in place update, then simply apply the patches in the v1.3.0 patcher, that I have made previously?

What exact error message is it?
Click to expand...
Never mind! I figured it out: I needed to go to the Security & Privacy Pane, and let the machine launch your file anyway. Initially, the machine thought your file was damaged, and that it could not launch it. But as I said, I got around that.

I have since successfully done a clean, fresh installation of OS 10.15.3 on my late 2012 Mac Mini, and migrated/copied needed files, folders, apps, settings, etc. from my most recent SuperDuper! backup. So far, everything is good. I am now doing the same on my 2018 Mac Book Air.

I didn't meant that EFI is changed, I only meant at "EFI level" as the apple bootloader startup manager (and this change also reflects/overrides to Refind bootloader icons).

Infact, it32 icon (and some others) are new "Catalina" encoded icons
Click to expand...
Since my EFI has not changed in a long time, it means it32 is not new. What is new is that the Catalina icns includes this old icon type.

jackluke said:
that's why you need to use the stock Catalina icns that I attached in previous post, that is contained also in the stock "createinstallmedia" Catalina Installer.app , avoid any third-party app to edit apple icns files that won't work in this scope, just use the best Image Editor : Preview.app (Catalina or Mojave version)

You don't need to extract or dump the entire iconset, just edit the 6th icon graphically/visually from the Preview.app , save and then set it as root .VolumeIcons.icns . At reboot in the apple startup manager you'll notice your custom icon.
Click to expand...
I understand that pasting over the it32 in the Catalina icns using Preview.app is one way to create a new working icon for my old MacPro3,1's Startup Manager. I would prefer a method that does not require copy and paste though, since I have many icons to fix. I will look at the other utilities and see if they can work, or I can create a new utility or script to do it.

No go for me still. Stuck on 10.15.1 as Patcher 1.3 won't install 10.15.2 or 10.15.3. It just reboots. And the USB option gives me an error upon install.

Have you tried the method in my post #8064 that is one way if you have macOS Catalina patcher that you used to creat the usb patcher you could also try the install to this machine method is another option if you have a copy of 10.15.3 downloaded indoor downloads folder
 
just to be sure here, i'm still on 10.15.1 and want to give 10.15.3 a go, does the 1.3 patcher download 10.15.3 now in the patcher ?

p.s.
big thanks to all of you working so hard to make this happen ...

To disable it, try this opening a Catalina Terminal window copy/paste (in one line):
Code: 
sudo kextunload /System/Library/Extensions/AppleStorageDrivers.kext/Contents/Plugins/AppleUSBCardReader.kext
Click to expand...

i think it did the trick Jackluke thanks many times for the assistance
