macOS 10.15 Catalina on Unsupported Macs

Is this somehow in relation to my post, or did you quote the wrong one?

Hi, can I ask an uninformed question of you? My machine is a 2011 MBP, 8,1. I assume I don't have a metal card and upgrading to 10.15.4 is not an option? I have Intel Integrated Graphics. Thanks.

The Metal supported cards for unsupported Macs are pretty much limited to MacPro models which have had graphic card upgrades on them.

OK after lots of test 'Cause I know I'm not crazy
I had to install the script well at the start because I did not believe that I could make Legacy Video Patch on 10.15.4 work without com.apple.security.libraryvalidation.plist = true
And I said to myself I will test without using it and well, I deleted the plist and it works, I just did a fresh installation and it works after deleted

NOTE: I always SIP full Disable

EDIT
Since Tuesday it is my 4th install to test the deletion of the file and it works

EDIT again

And I also test after having deleted I installed the script in false
sudo defaults write /Library/Preferences/com.apple.security.libraryvalidation.plist DisableLibraryValidation -bool false

and it also works

Out of curiosity, does playback of purchased content work reliably on your hardware configuration under the TV app? On my MacPro 3,1 with GTX680, the playback window almost immediately closes up when you try to resume a previously watched movie or tv show (that hasn't been explicitly downloaded). Weirdly, it seems that the first view of such content seems to play okay until the point where you pause and later try to resume.

Seem to have the same issue here, on same MacPro 3,1 / GTX680 / 10.15.3.

 

[jhowarth]

Music app is only broken by DisableLibraryValidation.kext, not by amfi_get_out_of_my_way or com.apple.security.libraryvalidation.plist methods. The boot-arg breaks Privacy permissions popups. The plist seems like the best solution, but it's unclear whether it works on a fresh install or if a user account needs to exist.

A secondary issue with 10.15.4 is (as discussed on Discord: join the server if you want more info!) that SIPManager.kext doesn't behave exactly as expected anymore. SIP is disabled, but AMFI acts as if it's enabled. This is why some people like myself, who disabled SIP in NVRAM with csrutil, were able to use 10.15.4 with no issues, but many using the patcher had problems. However, csrutil isn't an ideal solution since a PRAM reset will cause a non-functional system.

We're working on finding a fix -- my boot.efi patch is one alternative to SIPManager, but it's far from perfect. Modifying something that low-level and version-dependent is a bad idea. Hopefully a better alternative will be found (ideally, a fix for SIPManager). For now, 10.15.3 is the safest bet for people with non-Metal cards.

Hope that summary clears things up for some people. This has turned out to be weirdly complicated!

Edit: Added some more info.

I can confirm on a MacPro 3,1 with APFS ROM patch and a Mac ROM GTX680 that a clean install on a freshly APFS formatted external drive installs fine using a patched 10.15.4 installer created with Catalina Patcher 1.3.1. So the plist method has no requirement for a pre-existing user account.

Because you have a Metal capable GPU and you are using the stock "video frameworks", for non-metal GPUs with legacy framework AMFI needs to be disabled, anyway I am still on 19E264b .

My understanding is that there was still a general uncertainty about whether the installation of 10.15.4 needed a pre-existing user account for the plist method to disable AMFI. I assume that my test answers the question for both Metal and non-Metal configurations (since the video patches would seem orthogonal to this issue).

Not quite so, with a little rom-flashing and dremeling effort you can get a metal-supported nVidia K1100M or K2100M into an iMac from 2009 thru to 2011. The "how to" thread is on MR at:

Running MacOS 10.15.1 on a 2011 Macbook Air installed using Dosdude1 patcher. As a result of the current ongoing crisis, I am trying not to push my luck by upgrading to 10.15.3. Also, trying to install and use Zoom.us app to help support a volunteer fire brigade during lockdown, and have an issue that appears to be related to the OS.

When I log into Zoom app and start a meeting, the expected page displays, the light is on for the built in camera, audio works, I can see the outline of a rectangle for video, but no video. Same with other participants video on my screen. I can see their name, but no picture.

If I join the meeting using a browser, everything appears correctly.

I also run a High Sierra boot on my MBA, and when I install Zoom there, it works fine.

Anybody else see such a problem, and have any suggestions?

If you are using a newer version of Zoom and you don't have a GPU that's supports Metal installed it won't work here is a link to a previous version but it might or might not work as I can't get it let me giver permissions in accessibility to allow Camera and Microphone but works in Mojave https://forums.macrumors.com/thread....2183772/page-359?post=28294757#post-28294757 I believe its post 8969

2011 21.5” and 27” do not require dremelling for a MXM3.0a swap. The only requirement is to swap the X-Clamp at the back. I can’t speak for the 2009 and 2010 though.

I can confirm that disabling SIP by using csrutil before upgrade works perfectly. Before upgrade, I got into recovery and disabled SIP. Then, I did in-place upgrade by using patcher v1.3.1, and it worked.

No working video with Zoom on non-metal patched Macs: this is what I did on my Catalina-patched MacMini 2011 and MacBook 2009.
Zoom up to version 4.4.53909.0617 installed a mini-webserver which was found to be vulnerable to hackers. As of version 4.4.53932.0709 this webserver was removed and a different approach implemented. Alas, this version does not show video on non-metal patched Macs with Mojave or Catalina. Sentientbot posted a link to this earlier version, but that is not very safe. There is a workaround:

* Uninstall Zoom with the built-in uninstaller
* Install Zoom 4.4.53909.0617 (see link in post from Sentientbot #8.969: https://d11yldzmag5yn.cloudfront.net/prod/4.4.53909.0617/Zoom.pkg )
* It will automatically start, after that close zoom.us
* Right-click on the app zoom.us, ‘Show package contents’, go to folder Frameworks: remove item ‘Zoomopener’
* Use terminal to remove ~/.zoomus or have Finder show hidden files (Command-Shift-Dot), go to your home-directory and remove folder .zoomus
* Restart Zoom and check your video, it should all work by now

One drawback (as expected) is that clicking a zoom meeting-link you receive will not open Zoom automatically. No big issue: you can use the meeting number+password for that. The other drawback is this version of Zoom not supporting a nice dark mode. All other functionality is there and working.

Update 28-03-2020: The weird thing is, Zoom seems to identify my patched Catalina 15.3 as a version prio to 13.0 ......

now first i have an Kepler GTX 860m card....

first: i installed with 1.3.2 the new Catalina update with the Install on computer ... after restart and install i have an black screen (have no EFI but after 10sec after boot i have an screen)... with my AMD card i have screen.... legacy patch is unchecked.... can any one help me? SIP is disabled

after that i installed 1.3.4 and i have a black screen too...with my GTX card

must i restore via time backup it ? or have anyone an trick for me

Hello, I'm running 10.15.1 on 2011 imac, with NVIDIA GeForce GTX 765M, i installed the patched Catalina with my old graphic card and than changed it for the current one. My question is, is there a way to upgrade to 10.15.3 without changing graphic cards again, since this graphic card does not work until fully booted into the system. Which meens i have a black screen throughout the installation proces so there is no way for me to boot from the usb installer.

Yes this method worked for my MacBook 6,1.

Used a patched 10.15.3 USB installer for recovery, disabled SIP in terminal, restarted and used 'install to this machine'.

I also can't give Camera and Microphone permissions in Catalina "Security and Privacy" for non-metal zoom app, and apparently there is no way to add that through terminal, already tried this:

"tccutil reset Camera" and "tccutil reset Microphone"

But don't worked.

can you run some AmorphousDiskMark, set it to 5x 1gb file test, trying to see if you're Raid0 running properly. Here's my 2012 MBP Raid0 with latest Catalina 10.15.3, I've used Samsung Evo 500gb to compared with 2x Samsung 256gb (Raid0) setup. It runs pretty quick and i have no issues here.
View attachment 900443

How did you manage to make raid0 on catalina .3?
I managed to do it on catalina .1 but not .3

On .1 I installed it on an external SSD and then cloned it to my internal SSD RAID0 setup.
When i tried the same on .3 it did't work..
Tried both CCC and superduper.

How did you do it?

FYI, I have a mbp late 2011 17" with 2 internal samsung PRO 256GB disks.

If you have a metal supported card, you want to be using the Catalina Patcher 1.3.1 release that used the plist method for disabling amfi.

has link download 1.3.1. Dosdude1 should have left a download link for that version on the Catalina Patcher web page with a note that it should only be used for machines with Metal compatible graphics cards.

Seem to have the same issue here, on same MacPro 3,1 / GTX680 / 10.15.3.

I'm actually trying to get someone with a MacPro 5,1 where there is less patching to test this issue.

What exactly do you need tested? I have 5.1 Mac Pro with an rx 580 pulse in. I installed 10.15.4, clean install, via usb installer but before, I booted from a mojave usb installer to disable sip (it will not disable if you start from a dosdude Catalina installer).

Al you have to do is boot into the Catalina Patcher usb which is basically a recovery environment open the terminal enter csrutil disable

Use the Apple TV player app to try to play some content. What I have seen is that the very first playback seems to work. However if you stop the play back and later try to click on the content to resume the playback, the playback window briefly opens with content and the immediately closes. Note that this doesn't apply to downloaded content which always plays fine.
