you mean 2011 Macbook Pro ?
15" and 17" are supported, but their AMD graphic cards are not.
you must disable them, you can use several ways these days.
These machines only run on their on their integraded HD3000 graphics card, with acceleration when used patches.

the 13" 2011 Macbook Pro only has the Intel HD3000 graphics card, and should run fine with the patches..

Yea that is what I meant
 
Installed Catalina on a 2010 iMac that is upgraded with a GTX765 using Dosdude’s installer. Install goes fine, but no screen on reboot. I can access via VNC and confirm Catalina is installed and functioning. Ran post install patches, and made sure Legacy video was unchecked, but still no display. Repeated the entire install with the same results.

What am I missing? Installed over a Mojave partition if that matters.

I know, seen before, that the closer Catalina will be released, the more questions that have been answered before. Please, new members, take a time to read the whole thread.

So if i’m correct, the legacy video patcher is not selected by default this time for 2010-2011 imac’s ??

This would be great for all of us iMac users out there who have upgraded to a metal compatible graphics card..

If so, maybe this would also be a feature update to the Mojave patcher.
Wouldbe great to I think..

I hope someone can help me, I downloaded dosdude’s patcher and let it download Catalina. I then went and clicked install on this Mac, currently on the patched Mojave build by dossdude, and it installed.

Upon first reboot I get the circle with a line through it. I got this on Mojave too but O simply booted from the USB again to apply the needed patches. Well, I didn’t make a USB this time so now I have no idea what to do. I am using a 2010 MacBook Pro and trying to boot into cmd+R recovery leaves me at a grey screen. I could do internet recovery but I would lose all my files I stupidly did not back up. I have only access to a Windows PC and an old G5 PowerMac running OSX Leopard. Is there an easy way to get up and running?

I think it may be automatically installing the legacy video patch. I’ve tried installing several times today (2010 iMac with GTX765M) and the install goes great until the final reboot. i know Catalina loads, because I get prompted for voice over, but the screen is black. When I reboot and reload the installer and launch the post install patches, the Legacy Video patch is selected by default. Initially tried it over my Mojave install, but have since tried a clean install, and no go.

You'll need to upgrade your video card in order to get full graphics acceleration. As explained on the webpage:

Does this apply also to people like me that have an external eGpu (GDC Beast with Radeon RX 560 4GB) connected to a Mid 2011 iMac 12,1 (with AMD Radeon HD 6770M 512 MB)? Now I'm on High Sierra.
I'm not using the internal monitor (only a 4K display connected to the RX 560).

You could test this theory by replacing the replacement copies installed from the directories in "macOS Catalina Patcher/Contents/Resources/macOS Post Install/Contents/Resources/gfxshared".

frameworks/CoreDisplay
frameworks/OpenGL
IOSurface
kexts/AppleGraphicsControl.kext
kexts/AppleGraphicsPowerManagement.kext
kexts/AppleMCCSControl.kext
kexts/IOGraphicsFamily.kext
kexts/IONDRVSupport.kext
privateframeworks/GPUSupport.framework
privateframeworks/SkyLight.framework

with copies extracted with Pacificist from "Install macOS Catalina Beta/Contents/SharedSupport/InstallESD". Just reapply the 'legacy patches' with those Catalina copies and force rebuild the kernel cache.

You'll still have the Telsa patches installed but they shouldn't interfere with the Kepler card running properly. If you are worried, boot from the usb installer, delete the files below from
/System/Library/Extensions using the Terminal window and use the post install patcher (with no patches selected) to force rebuild the kernel cache.

GeForceTesla.kext
GeForceTeslaGLDriver.bundle
GeForceTeslaVADriver.bundle
NDRVShim.kext
NVDANV50HalTesla.kext
NVDAResmanTesla.kext

I had suggested awhile back that Dosdude1 add a 'Disable auto patching' option to the Catalina Patcher (primarily for the benefit of MacPro 5,1 users) which would create a usb installer with auto patching inhibited.

@dosdude1 @ASentientBot Macmini mid 2010 (Macmini4,1) 100% on both CPU due to mdworker_shared (multiple instances) i'm leaving it running for 2 hours (70° C with 5500 RPM fans) to see if process are automatically terminated after file indexing.

[SOLVED] After 2 hours processes has been terminated and CPU and temperature is OK!

it´s normal. tasks afyter a new installation consumes a lot of resources. Spotlight the more (mdworker).

Use another mac to make the bootable USB from the patcher tool and use that to boot and run the post install patches

Hi, Thank you all for your hard work.
IS there any way to activate continuity on MBP mid 2009 13-inch Catalina b5 with a bluetooth dongle 4.0 LE ??

I've tried the continuity activation tool app, but it asks for the main password to make changes >>> then nothing really happens !!!!!
