I was able to install Catalina on my late 2009 27" iMac. But I was trying to disable system integrity protection and am running into issues. I startup the iMac holding Command+R. Once in the recovery mode I open terminal and type:

csrutil disable

I get:

csrutil: failed to modify system integrity configuration. This tool needs to be executed from the Recovery OS.

And then I try:

csrutil status

And I get:

System Integrity Protection status: unknown (Custom Configuration).

Configuration:
Apple Internal: disabled
Kext Signing: disabled
Filesystem Protections: disabled
Dtrace Restrictions: disabled
NVRAM Protections: disabled
BaseSystem Verification: disabled

This is an unsupported confutation, likely to break in the future and leave your machine in an unknown state.

Any idea what I should do?

If you installed Catalina from DosDude1's patcher, then SIP is already disabled and the result is what you posted when entering csrutil status in terminal. Do NOT re-enable SIP on your patched OS, otherwise it will break the patches and you'll need to run the post install patcher again.

Nothing. This is necessary for an unsupported Mac to run. Keeping X-Protect and MRT up-to-date is more important. SilentKnight is handy for that task.

I've been trying to install Catalina on my Imac 11.2 3.06 GHz Intel Core i3 for a week, but without success. During the installation, 4 minutes before the end, the computer restarts and my computer starts up as nothing happened. Although I have taken every step shown in the video, failed. Where do you think I am going wrong?

You have to use it from Recovery Partition. Command+R when boots.

The identical iMac here would not complete the Catalina install from USB until a full SMC and NVRAM reset was performed. It needed three bongs to clear the NVRAM. Then, boot directly into the v.1.4.4 patcher and perform the install.

I'm posting this from a 2009 iMac and seriously, it's great. This is the 11,1 model but it has the ATI 4850 graphics, and I didn't realize at first I could install it on this machine because of the dire warnings for ATI 5x/6x owners. The 4850 being even older, I figured it wouldn't support acceleration either. So I've been pleasantly surprised. I've seen absolutely no performance hit vs High Sierra on the same hardware.

Anyways screenshot for bragging rights. If this remains a stable system in a couple of weeks I might patch my writing laptop too (it needs to not break, the iMac is more a convenient extra machine we have, it's allowed to break).

Kudos to dosdude1 and crew!

I know that camera issues have been dealt with a lot, but I couldn't find what happens to me every once in a while: Third party apps like Zoom (patched with Dosdude's non-metal script) or Jitsi Meet can’t start the camera on my 2011 MBP. The LED is on but the screen is black. Restarting the machine helps. Now I figured out that starting FaceTime triggers a restart of the camera: The LED goes off and on again. The camera delivers to both apps and I can quit FaceTime and continue with Zoom. You're free to interpret this as a workaround - or a question: Any suggestions to get rid of this issue entirely?

Do both apps have Camera permissions in the Security & Privacy CP?
 
Hi, thanks so much for the great job creating the install patch, the catalinaotasufix and the USBCoreOpenAPFSloader.

I just updated my macbook 5.1 to Catalina 10.15.7, I had a problem with an infinite reboot loop but it was solved by clicking on the rebuild cache option that appears after installing the post-install patches of dosdude1.

Everything works perfectly in this update so far except the trackpad, it is not recognized in the preferences panel. I saw that there was a trackpadmb52.prefpane.zip file by @TimothyR734 , I would like to know if that same file could work for my macbook 5.1 or if a modification is necessary.

Thanks for help.

Has a SMC reset been performed? The trackpad is on the USB bus.

Heck with it, did the laptop this morning. No regrets. So far, AirDrop crashes Finder when you select it, and iMovie 10.x won't run. Nothing show-stopping for a writing computer.

Hey all,

I tried searching for someone having a similar problem but couldn't find anything yet.

I'm getting errors saving/downloading files saying that my disk is full. It's not specific to any programs since thus far it has happened to me while using GIMP, downloading a file on Chrome, and another program (can't recall at the moment). It seems to be happening at some point after I take a screenshot.. but that may be a coincidence. It also seems to resolve itself after a reboot. I lost a bit of work because of this already and don't want to have to restart to regain file-saving capabilities.

Should also mention I'm using a 1 TB ssd from OWC on a MBP5,3 and have over 700GB free.

Any ideas?

Not until now, but I have now. Thanks a lot. I'll report if the problem should persist. Since my camera issue didn't occur very often, I can't tell right now.

Ok, that was quick: tccplus hasn't changed anything. But with FaceTime as a workaround, I can deal with it.

EDIT: Neither Photo Booth or iMovie (10.1.12) can start the camera, whereas Signal can... 🤔 But again: I'm fine.

Don't know how much fun video editing would be with your MacBook. But I found out, that 10.1.12 (which I found on a Mojave MacBook) works on my non-metal MBP8,1.

Damn!
I just solved the problem!(At least for this session.I wonder if it works after a restart)
First you do (optionally) xattr -lr <path_to_app_bundle> to get the list of the files that cause the error.
Then you do xattr -cr <path_to_app_bundle>.
And now you are finally ready to change the code signature using sudo codesign -f -s - <path_to_app_bundle>.

For my case with chrome browser I used the following <path_to_app_bundle> :
/Applications/Google\ Chrome.app

I tried doing what you mentioned but it didn't work for me. Any idea what I'm doing wrong? Not a terminal expert at all. Attached a text file. Thanks.

Update - I changed in System Preferences/General to allow app store only and then change back to third parties. Now it is working.

Attempted update on iMac11,2 scragged the APFS partition. Avoid this Beta 😷
