⭐⭐⭐NEW UPDATED GUIDE IS HERE; https://www.youtube.com/watch?v=qv1C3pHnUYs ⭐⭐⭐ I show you how it's possible to install Mac OSX 10.15 Catalina on to an unsupported Macbook, iMac, Mac Pro & Mac Mini. To be clear this guide shows you how to install Mac OS Catalina, it is up to you to backup your data first and use Catalina at your own risk, I am not responsible for any loss of data etc...For me as you can see I installed Catalina and it worked for me, however due to unforeseen circumstances I can't help with all install steps if it doesn't work out for you. I also can't support or guide you on the use of additional Apps you may install like for example Office (word, powerpoint, excel), Final Cut Pro, Photoshop etc... they may work - they may not. However do help others in the comments if you get Apps to work what other are struggling with. Using dosdude1 Patcher; I have successfully install OSX Catalina onto a 2009 Mac Pro.
