macOS 10.15 Catalina on Unsupported Macs

[1jak0]

Hello!

I was on Cat 15.3 and my fan started making a weird noise (since Cat 15.5 was available I didn't take it seriously)
now after two weeks problem reappears ... I put manual setting to 5000 RPM and only got half capacity and the weird noise continues

any idea how to solve it without a clean install?

Per my experience the Apple Watch generation has nothing to do with it. As mentioned earlier both of my Macs do have BT 4.0 and I'm using Unlock with my Apple Watch Series Zero (1st Gen) which is also BT 4.0 only.

I agree.

I would say your fan is faulty. It´s very easy and cheap to replace it.

I have a weird problem with Catalina 10.15.4 and my Radeon RX580. Every time the computer wakes from sleep, it automatically puts my monitor into HDR mode, even with it unchecked. I have to go through this long list of turning off the monitor, enable/disabling the HDR mode, and re-selecting color profiles in order to get it back. Is that a patch issue?

Try using a refresh rate that only allows 8 bpc output? (HDR requires 10 bpc output). For example, an HBR3 display can do 4K up to 95 Hz at 10 bpc using CVT-RB timing, so use 96 Hz.

Any more news on the Safari extensions problem?

I have recently acquired a mid-2011 MacBook Air, and after a fresh Catalina (-patcher) install, it is impossible to enable my 1Blocker Safari extensions. It's impossible to enable any extension in Safari for that matter. I have tried all the workarounds, except for installing 10.15.2 first to enable the extensions to keep them enabled up to 10.15.5.

I have reverted the MacBook Air to High Sierra for now, but I would like to be able to get back to Catalina. But these non-functioning extensions are a dealbreaker to me.

For those in the same boat: I have been able to get my Safari extensions enabled without having to go the complex and time-consuming route of first installing a pre 10.15.3 Catalina, enabling the extensions and then updating to 10.15.5.

I'v managed to get the Safari version from 10.5.0 running on 10.15.5, by replacing /Applications/Safari.app and the Safari*.framework directories in /System/Library/PrivateFrameworks. I have extracted these files from a 10.15.0 installer using Pacifist. Short manual:

Be careful, this requires some knowledge and insights in the working of .pkg packages. But all in all it can be done in a few minutes, when you have the necessary files ar your disposal.

- Extract /System/Library/PrivateFrameworks/Safari*.framework en /System/Applications/Safari.app from the 10.5.0 installer using Pacifist
- Make sure the system partition is mounted writable (sudo mount -UW /)
- Backup /Applications/Safari.app and /System/Library/PrivateFrameworks/Safari*.framework.
- Replace /Applications/Safari.app and /System/Library/PrivateFrameworks/Safari*.framework with the versions extracted from 10.15.0
- reboot
- again: Make sure the system partition is mounted writable (sudo mount -UW /)
- Open Safari and enable extensions. Note you're now running the Safari version from 10.15.0.
- Restore /Applications/Safari.app and /System/Library/PrivateFrameworks/Safari*.framework from the backup
- Reboot

When done correctly, you'll be back on the latest Safari version, but now with your extensions enabled.

You are using a free Mac Fan Control version which is only allows monitoring. Are you sure you don't have to pay for the full version?

Could be a dust bunny or long hair in fan assy. Try compressed air before replacing that fan?

 

[DWomack]

Yes. Create a new patched USB and install over.

Works! Thanks for the help.

I want my 144hz refresh rate, though.

What monitor do you have? 144Hz is high enough at some resolutions to require 10 bpc. Does the display's refresh rate also change when the computer wakes from sleep? If so then my idea won't work.

LG 27GN850-B

The refresh rate stays the same, it just turns on HDR without *checking* the box in Preferences > Displays

I have to check it to change it to *true* HDR, then uncheck it, then reset my monitor to take non HDR.

At HBR2 link rate, 2560x1440 144Hz should be enough to disallow 10 bpc. Your display probably supports HBR3 link rate so you would need 201 Hz to disallow 10 bpc. Or you could just take the 144Hz timing, increase the pixel clock to 864 MHz, increase the horizontal sync/porches so the horizontal refresh rate is within range, then increase the vertical lines until the vertical refresh rate is in range (this can only work if the display supports 864 MHz).

Or override the EDID to remove HDR option but maybe you want to use HDR sometimes?

The HDR is abysmal on this monitor. I don't see myself using it enough to suffer through the process of disabling it after wakeup. How do I override the EDID? Hackintool? What is the process of that? Just disabling HDR?

Hey, @jackluke I remember you posted a message include fixing unbootable recovery with com.apple.Boot.plist or in Preboot or something else. But I can't find this post. If you remember can you share with me thanks.

or I totally remember wrong

Hackintool might be one way to do it, but it doesn't have an option to remove HDR.

Try my script at https://gist.github.com/joevt/32e5efffe3459958759fb702579b9529

[[ -d ~/edidworkfolder ]] || mkdir ~/edidworkfolder # create a work folder
cd ~/edidworkfolder # change the directory to the work folder
source ~/Downloads/EDIDUtil.sh # load the commands from the script
loadagdc # read the EDID from AGDCDiagnose output
listedids # list the EDIDs that were loaded
useedidnum 1 # work with the first EDID (change the number to whatever EDID number contains the Dell U4919DW string)
dumpedid # show the current contents of the EDID (if you have edid-decode installed, then you can also use the decode command)
deletectablocktype 706 # delete any HDR static metadata
deletectablocktype 707 # delete any HDR dynamic metadata
dumpedid # show the results
makeoverride -m # in the work folder, make an override vendor folder containing the display override file; -m : use the display year and month of manufacture naming convention
installoverride -l -m # install the created override; -l : use /Library/.../ instead of /System/Library/Displays/Contents/Resources/Overrides/.
# disconnect display and reconnect to use new override

So after I install that repo and run this command, it'll have everything except HDR?

I think so. I didn't try it with mine. I have tested other EDID overrides that do remove HDR from my display. That means if my suggested changes don't work, then there is other stuff that needs to be changed and we can try again.

Hey guys! Downloaded and installed the Safari Technology Preview on my Macbook 8,1 with Catalina and to my surprise, this is the message that appears when I try to activate an extension. Tried in safe mode and the message appears there too. Any chance to find what causes it?

 

[BubbaMc]

Not surprised as that is an ATI card instead of a Nvidia one. The Kepler drivers have had broken DisplayPort on the GTX 680 since the beginning under Catalina.

is this still the case? Any workarounds?

My 5,1 won‘t output video via DisplayPort under Catalina, wondering if anything can be done.

Only solution I have found is to use two Atlona DP200 trought the two DVI. Connected to two Cinema Displays.

I'd like advice to boot Dosdude Patchers from an internal drive instead of a USB.

My setup today:

MacPro 3,1 2x3.2GHz QuadCore Xeon
1 week old Sapphire Pulse Radeon RX 580 8GB - but no boot screen.
Catalina Patched from Dosdude1 install USB before installing the New Rx580 GPU.
SSD startup on the SATA port not in one of the 4 drive bays.


It is a pain to pull/swap GPU cards to reboot from USB as there is no boootscreen, so I got to thinking.

Can I install the future bootable Dosdude patchers on an internal drive instead of USB? That would work solve my problem wouldn't it?

If so, with the Startup disc control panel pick it so I can more easily reboot from it to install new versions on 15.5.6 or whatever comes next.

Thanks.

That is not going to solve anything. Still you will have no boot screen.

I understand. Thanks for the start. If I am in the right forum, I will continue.

I can install the Dosdude Catalina patcher on an internal storage. I can choose to boot from it using the Startup Controil Panel. And the Patcher disk boots just like the recovery disk. Seems fine, but it isn't.

However, when I select reinstall MacOS I get a Dosdude error that "This version on MacOs is broken.." - suggesting the patcher and the download os are out of step according to Dosdude's FAQ page. (I've tried a fresh re-download of the patcher and the OS a couple times and the error persists.)

Further, when trying to select the SSD as the startup disk it does not appear.

Finally, when rebooting I need to then unplug the patcher internal disk. But then then only the recovery disk boots, but then I can select the functioning Catalina SSD and I am back to normal.

So I am thinking I have missed a step to "patch the patcher" to recognize APFS volumes. It all feels like I am so close to getting this to work.

Does all that make sense?

I strive to switch from an internal boot volume of Catalina 15.5.5 to a Catalina Patcher internal disk and use only the OS Startup Control Panel of either to switch betwixt the two volumes. - without pulling cables/disks and without using boot screen.
