Problem installing Catalina 10.15.6

Recommended Posts

Posted (edited)

Hi.
I have a problem starting the installation of Olarila Catalina 10.15.6.
I downloaded the image and generated the pendrive using Balena Etcher portable.
When starting the pendrive and select Boot macOS Install, this appears:

Try all 4 USBs on the notebook and the problem is the same.
Any suggestion?
The notebook has:
CPU: i7 4710MQ
RAM 12GB
video: intel 4600

Hello MaLd0n.
It worked perfectly.
Now another problem.
When it is installing and there are 2 minutes left to finish it says:
An error occurred while preparing the installation. try running this application again olarila catalina.

Searching the forum I understand that I should apply
EmuVariableUefi or use one full dsdt patched
Is that so?
If so, is there a tutorial on how to apply the EmuVariableUefi?
Regards

Hi MaLd0n!

The dsdt you sent didn't fix the problem. :(
I'm going to try to build an OpenCore.
I will comment on how I finish.
Thank you for you time!!.
