• Installed Catalina using CatalinaPatcher on my 4,1 MacBook Pro without much issue and it ran perfectly for months. It sat unused for a month or so and when I turned it on the other day, it goes through it's verbose startup (normal), switches to the white Apple boot screen, progress bar gets to the same two thirds of the way and the MacBook reboots and goes through it all again, and again.
• At last I have solved myself 😆 I have discovered the origin of the prblem! The usb stick for installation created with catalina patcher and also a clone drive of the system with ccc5 aren't containe the EFI folder in EFI partition, I have simple mounted all efi partition and copied efi folder from system disk to usb stick, that's it!
• You mean DOSDude1 Catalina Patcher. Yes, lots of people here use it for old Macs. Just be aware you won't want to perform interim OS updates without checking for known problems or patch updates. Although security updates and other miscellaneous updates are generally safe. You just down't want to go willy-nilly and update the OS.
• Thinking I had read that it has to be disabled for Catalina Patcher to work I came to Reddit and found this string confirming this. My question is could there be a possible work around to enable iMovie to work. The data on this new version says it requires Catalina 10.15.6 which is what I am running from an external drive.

Read the full changelog

macOS Catalina Patcher (formerly macOS Mojave Patcher, macOS High Sierra Patcher and macOS Sierra Patcher) is a small yet powerful tool that can help you create a bootable USB drive that can be used to install macOS Catalina on Mac computers older than mid 2012, basically acting as a macOS Mojave patch for unsupported Macs.

The tool extends the list of compatible hardware to the Mac Pro, iMac and MacBook Pro computers released in early 2008, Aluminum Unibody MacBooks or MacBooks Air manufactured in late 2008, or white MacBooks and Mac Minis produced in early 2009.

Get the macOS Catalina Installer app and make sure you have access to a compatible USB drive

To be able to use the app you must make sure that you have a USB drive that has at least 8 GB available, and that you have the macOS 10.15 Catalina installer app on your Mac.

Note that you can download the macOS image from the Mac App Store application only on a machine that supports Catalina: otherwise, you must find an alternative solution.

For your convenience, macOS Catalina Patcher offers you the possibility to download the image through its interface: just navigate to the Tools menu.

At the same time, you must prepare the USB drive with the help of the built-in Disk Utility application: just format the disk using the Mac OS Extended (Journaled) standard.

Easy to configure patcher tool that can create bootable macOS Catalina USBs

Within the main window, you must simply load the macOS 10.15 image you want to use and select the target USB drive. The app will verify the image to make sure everything is OK, and all you have to do is press the Start Operation button.

You have the option to monitor the process in the macOS Catalina Patcher main window, and the utility lets you know when the task is complete.

Worth mentioning is that after you install the OS by using the macOS Catalina Patcher bootable drive, you must launch the macOS Post Install utility to get access to patches specifically designed for your Mac’s model.

Make a bootable drive that allows you to install Catalina on unsupported Macs

Bottom line, if your Mac has been manufactured before early 2008, chances are that you will not be able to install macOS Catalina on your computer.

All things considered, macOS Catalina Patcher is a small and user-friendly utility designed to help you bypass this limitation if your Mac is not in macOS Catalina's compatibility list, created to be used as an unsupported Mac Mojave patch.

Updates
Important Notes:

• Using APFS is REQUIRED in Mojave in order to receive system updates via the normal Software Update method. If you choose to continue using macOS Extended (Journaled) as your filesystem type, you will NOT receive System Updates via System Preferences. If you are not using APFS, you can follow the 10.14.1 installation steps below.


• After applying ANY system update via Software Update, re-applying post-install patches using your Mojave Patcher installer volume will most likely be necessary. If you install a software update and the system fails to boot afterwards, this is what needs to be done.

Using Catalina Patcher

10.14.6

10.14.6 can be updated normally via Software Update if using an APFS volume, and will need to be patched using an installer volume created with Mojave Patcher version 1.3.2 or later after installing.

10.14.5

10.14.5 can be updated normally via Software Update if using an APFS volume, and will need to be patched using an installer volume created with Mojave Patcher version 1.3.1 or later after installing.

Catalina Patcher Recovery Mode

10.14.4

10.14.4 adds new changes that ARE NOT patchable by the post-install tool of Mojave Patcher v1.2.3 and older! Before updating to 10.14.4, you you will need to use the latest Mojave Patcher version to create a new installer volume, using the 10.14.4 installer app. Then, update to 10.14.4, either by installing via Software Update, or by just using the installer volume you've created to install.

10.14.3

If you are currently running 10.14.1 or 10.14.2, you can simply use the Software Update pane of System Preferences (if using APFS) to apply the 10.14.3 update. Once the update is installed, you will most likely need to re-apply post-install patches to get the system to boot again. This process is detailed in steps 8 - 10 above. If you are currently running 10.14.0, you'll need to proceed with the 10.14.1 update method described below.

10.14.2

Patcher Catalina

If you are currently running 10.14.1, you can simply use the Software Update pane of System Preferences (if using APFS) to apply the 10.14.2 update. Once the update is installed, you will most likely need to re-apply post-install patches to get the system to boot again. This process is detailed in steps 8 - 10 above. If you are currently running 10.14.0, or are using a non-AFPS volume, you'll need to proceed with the 10.14.1 update method described below.

10.14.1/macOS Extended (Journaled) volumes

The Mojave 10.14.1 update does NOT install properly on unsupported machines, and could result in an unbootable OS. If you want to install the 10.14.1 update (and are not currently running 10.14.1), perform the following steps:
• Download the latest version of Mojave Patcher
• Download the installer using the Tools menu of Mojave Patcher
• Create a patched USB installer
• Boot from that, and install 10.14.1 onto the volume containing an older release.
• Once done, apply the post-install patches, and you should now be on 10.14.1.
