MacBookPro8.3

[Srnka]

We've installed the Catalina patch, but we currently have a problem with csrutil enabled, because Recovery OC is not just the one over the Internet, but there is only some local csrutil. Is there any way to do this?
Also, we can't find a firmware update for MAcBookPro8.3 for the GPU, not all Apple updates are compatible.

My recommendation:

Turn off system integrity protection.

Boot to the recovery partition, open terminal and enter:
csrutil disable

Then reboot.

Now you may be able to install whatever "patches" you want.

I routinely DISABLE SIP on all my Macs. Never caused me a problem yet.
