I also use the Catalina Patcher app, and noticed an update. Go to the Dosdude1 web site. The download page for the v.1.3.4 version tells you that there are real problems with 10.15.4 and the patches for unsupported Macs. MacOS Catalina Patcher is a third-party tool developed by dosdude1, who has developed trusted, similar tools since macOS Sierra. Head to dosdude1.com, and find the device that you want to install Catalina on. On the same site, there is also a video tutorial that will take you through the process of installing Catalina, but I'll describe this as well. First, download the macOS Catalina Patcher from dosdude1.com. Open the Catalina Patcher app.

Question :

I would like to get all Macs in my network on macOS 10.15 Catalina. I have some older models (like a MacBook Pro 13″ Late 2011, a white MacBook 13″ Late 2008 and a Mac mini Mid 2007) that are officially unsupported.

Is there any option to get macOS 10.15 Catalina running on unsupported Macs ?

Answer :

Yes, there is.

It is possible to install macOS 10.15 Catalina on various officially unsupported Macs using the Catalina Patcher by dosdude1.com :

But before you do so, make sure that you :

1. do not do this on your primary Mac !! as this is unsupported by Apple, do not do this on any Mac that is vital to you for your work or study !! using this software is not entirely hassle-free, only do this on Macs that are your secondary computer !!
2. have a 16GB USB-stick that you can reformat for this
3. have a stable internet connection (preferably an Ethernet-cable network connection to an internet modem with a high-speed internet connection)
4. read this post : fixed : installer error 16GB USB-stick not large enough for 10GB Catalina Patcher
5. and read this post : fixed : “Convert to APFS” option greyed out in Disk Utility (in Catalina Patcher)
6. read the additional info on dosdude1.com
7. follow the instruction video by dosdude1.com
8. see if your Mac is listed as a ‘Catalina Patcher supported’ Mac before you even consider doing this

Shortlist of ‘Catalina Patcher supported’ Macs (see sosdude1.com for in-depth specs) :

• any Mac released since 2009 ( iMac / Mac mini / Mac Pro / Xserve / MacBook / MacBook Air / MacBook Pro)
• all desktop-Macs released in 2008 ( iMac / Mac Pro / Xserve )
• most laptop-Macs released in 2008 :
  • all MacBook Pro models 2008 and newer
  • any aluminum-MacBook
  • nearly every MacBook Air ( any MacBook Air, except the ‘1st Generation’ / ‘Early 2008’ )
  • only the last generation white-MacBook ( Early 2009 )

…so, in your case :

• yes, this Catalina Patcher can be used on a Late 2011 MacBook Pro
• no, this Catalina Patcher cannot be used on a white-MacBook 13″ Late 2008, only on newer white-MacBook models
• no, this Catalina Patcher cannot be used on a Mid 2007 Mac mini, only on newer Mac mini models

That’s it !

• 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.

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 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.

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.

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.

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.

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.
