Download Osafo Catalina Installer (609.2mb)
Request Bootable OsafoCatalina 10.15.5 (9.64gb)

macOS Catalina 10.15.5 On Unsupported Macs (Especially MacBook 4,1)

Hurray !!!

Osafo has done it again. macOS Catalina 10.15.5 (Osafo Edition) running on MacBook 4,1 and all unsupported macs dating as far back as 2006 - 2008 (list below). The hallmark of my macOS research is finally here. 

My process for installing macOS Catalina 10.15.5 is of 2 folds. 

1. Osafo Catalina Installer - (a 690.2mb dmg to prepare the macOS Catalina installer on your own).

2. Osafo Catalina - (a 9.64gb already prepared bootable Catalina installer).

A link to downloading the Osafo Catalina Installer is provided below (this requires and assumes you have already downloaded "Install macOS Catalina.app file from mac app store or anywhere from the internet to use my installer to prepare it to make it work on unsupported macs).

On the otherhand, those interested in the already prepared 9.64gb bootable can request from me as I have not uploaded it yet due to the large size.

I have prepared everything for you. Just download the Osafo Catalina Installer file below and use to prepare your bootable catalina installer on a 16gb usb drive or partition. Alternatively, requrst from me the 9.64gb bootable installer, write unto a 16GB usb or external drive and install. The research continues unabated for unsupported macbooks.
