macOS 10.15 Catalina on Unsupported Macs

[K two]

Hi @K two
here also on MP5,1 10.15.4 (19G266) 0% CPU usage for "deleted" like @serafin79

View attachment 902025
Have you tried using Onyx, because I often had abnormal CPU usage after some Mojave upgrades which I resolved after using Onyx -> Maintenance.

Maybe related to Legacy Video Patch which should not be present in a MP, this a Mini3,1. Used Maintenance previous also re-installed all of the patches, rebuilt Caches - have not yet killed a chicken.😎

Sadly neither an upgrade over a working 10.15.3 nor a clean install worked for me using the latest 1.3.5 patcher and 10.15.4 downloaded USB set with APFS patch off and post install off on a MPro 3,1 with patched bootrom and GTX680 card. Alrhough the install apparently completed the system enters an endless bootloop as the boot progress bar finishes loading. I tried booting into recovery mode from the patcher and switching off SIP but still no good. I do see the cursor for a second before the boot loop starts.

PS, I am aso seeing the kernel panic multingual screen for a few seconds when booting from the USB booter; it goes past this screen after a few seconds but it is a new phenomenon for me.
It seems like more work is still needed unfortunately.

Oh, applying the Post-Install patches and forcing a cache rebuild worked; it has gone past the bootloop to the setup screen

Just to say a huge thanks to Dosdude and other guys for the hard job done
👍😀

OK, I downloaded the full OS 10.15.4 installer via dosdude1's patcher, and am currently doing a clean, fresh, "virgin" installation of OS 10.15.4 on my MacBook Air, via the just completed SuperDuper! backup of my "just prior" clean OS 10.15.3 system. Assuming all is well (I suspect it will be), I'll then do it on my Mac Mini. Worse comes to worse, if at any time in the coming week issues arise, I still have the OS 10.15.3 prior system backed up (via SuperDuper!) and can restore from.

I'll provide updates as things progress.

 

[nekton1]

Yes, clean install seems to be OK after applying post-install and forced cache rebuild. Thanks dosdude1 and everyone else.

I've got a strange sleep issue with the GTX 680 running Catalina 10.15.4 (also happened with 10.15.3) on a MacPro 5,1. I used Catalina Patcher 1.3.5 to install 10.15.4 (previously used 1.3.4 to install 10.15.3). If I let the display go to sleep, then the video does not come back when trying to wake the screen again. Unplugging the DP cables and cycling the monitor has no effect. The weird thing is that this only affects the DisplayPort connection and not the HDMI connection from the GTX 680. If I never let the screen sleep, then the DP ports work correctly. Also, if I start the computer with the monitor attached to the HDMI port, then the DP port also doesn't work.

DisplayPort does not work properly on those nVidia cards under 10.15. Use either HDMI or DVI only.

I successfully installed 10.15.4 !!! I placed the Asentientbot's LibraryValidation script in /Library/LaunchDaemons folder. Then downloaded the update before restarting to install I ran jackluke's catainlinaamfixfix4 script in the terminal. Once the update was installed I rebooted in the Catalina Patcher entered in the terminal csrutil disable then applied the post install patches except the Libraryvalidation patch all went well but no Night shift but goofed I rep

laced the border fix HOToolbox as well as CoreBrightness no luck but I did a command-v for verbose no AMFI warnings so reinstalled 10.15.3 then went through the process again but this time I just replaced the CoreBrightness from March 13th even though no Night Shift in the display settings Shifty works for Night Shift for now

This is why I thin Night Shift is missing from the Display Settings, Notice the one from March 17th says 406 compressed and the one from March 13th does not. I noticed this with HIToolbox as well

That's odd because I recreated my 10.15.4 patched installer with Catalina Patcher 1.3.5 earlier this evening and did a clean install onto a freshly APFS repartitioned external drive attached to a MacPro 3,1 (APFS ROM patched) and GTX680 (Mac ROMs). No problems whatsoever.

Wouldn't Catalina Patcher 1.3.5 be easier?

No rational explanation for the issue but the difference may be because my boot SSD is an NVMe blade on an internal HighPoint 7101a PCIe card.

Nice work!

Filesystem compression is lossless and shouldn't affect anything -- like firmlinks/hardlinks, fragmentation, etc. it's totally invisible to anything high-level. The APFS drivers take care of it under the hood and provide the exact same file to anything that asks for it. I suppose compressed files may read slightly more slowly, but that's all. Some more info about it here.

I don't know anything about the Night Shift fix itself, though. I may look into it at a later time if nobody else does.

I thought a patched Catalina installer wasn't seeing SSDs on PCIe cards as an installable target. Did that get changed?

 

[honestone33]

Well, things are not looking good. The clean installation, migration, and setup went fine on my Mac Book Air. It then told me I needed to "enable" the extensions for my Logitech mice, which I did via System Preferences. It then told me a restart was needed, which I did. But for the second time, for the bootup process, the progress bar gets to the very end, but nothing happens. Again, this has happened twice, and just tried again. Almost at the end of the bar, but if it does not work, am going to restart the Air from the SuperDuper! backup, and go back to OS 10.15.3. I then might try the OS 10.15.4 Combo Updater.

Really frustrating Apple will not allow folks like myself to download the full installer directly.

Booting from the backup right now.

Dosdude has a new Catalina Patcher out that fixes the issues with installing 10.15.4 and you can use the patcher to download 10.15.4

Did you use the latest Catalina Patcher version (1.3.5) that I just released today? That takes care of all the 10.15.4 issues, and will download a 10.15.4 installer.

Yes I did, and it did download the OS 10.15.4 installer. As I stated, the clean installation, migration from my just completed SuperDuper! backup, restarting, and setup all went well. But after needing to take care of a Security & Privacy issue for my Logitech extension, I was told to restart. Well, that is exactly what I did, but as I said, the boot process got all the way to the end, ie, the progress bar reached the end, but then nothing happened. I of course was expecting to see the desktop appear. So, restarted again, and same thing happened. Restarted again, same thing happened. Repeat same thing, same thing happened.

So, I am now in the process of doing a clean, fresh installation of OS 10.15.3, downloaded with the prior version (I think 1.3) of your patcher. It's in the process of collecting all the information I want to migrate from the backup. Hopefully all that works as expected.

Assuming it does, I am going to apply the OS 10.15.4 Combo Updater that I just downloaded directly from Apple. Can you tell me why in earlier correspondence between you and I that you told me not to use the Combo Updater? Seems like folks, for the most part, are having success doing that.

Do you think it could be possible that maybe the Logitech extensions might not be supported in 10.15.4

 

[honestone33]

That would be a drag.

In any event, successfully back on 10.15.3. It also mentioned the same thing about the Logitech extension, but this time, I skipped it. I will probably be "bugged" by the OS later, but that's OK.

What was also bizarre is that after I initially was able to "get into" OS 10.15.4, it did not show my external SSD connected, even though I still had it plugged in. But OS 10.15.3 does. So it seems there are issues with the OS 10.15.4 full installer/resulting installation.

By the way, I could have chosen instead to do a SuperDuper! restore of ALL the files I backed up earlier, and that would have included everything associated with OS 10.15.3. But I wanted to see how it would go with a clean, fresh installation of OS 10.15.3, and then a migration. As I just said, it went well.

I'm going to try the OS 10.15.4 Combo Updater next.

 

[honestone33]

It sure is taking a LONG, LONG time to apply the Combo Updater! Still has 4 minutes to go, and I started it almost an hour ago! Doing a fresh, clean installation of OS 10.15.3, then a migration from my SuperDuper! backup was dfinitely faster.

Sure us frustrating the clean installation of OS 10.15.4 downloaded with the latest version of dosdude1's V1.3.5 of the patcher did not work!
[automerge]1585458442[/automerge]
OK, FINALLY done! I guess my earlier gripe about OS 10.15.4 not seeing my external SSD was premature, as after competing the update to OS 10.15.4 via the Combo Updater, my external SSD was again not "visible". But after shutting down and unplugging the SSD, then starting up again, and after getting to the desktop, plugging in the external SSD, it was recognized.

Also, "griped" about the Logitech extensions, but fixed that via System Preferences.

So, I guess everything is OK. Anything earth shattering I will see in OS 10.15.4?

 

[TimothyR734]

I am liking it it seems a bit slow getting into the desktop after logging in. I had to reinstall iTunes and iPhoto with retroactive to get them working again but other than that its runs smooth

 

[nekton1]

Anybody know whether the Innie/Lilu method still works to make external disks on PCIe expansion cards appear as internal disks with 10.15.4?

MBP6,2 no Night Shift Tab on SP despite all patches installed... Am I missing something...?

 

[pwm86]

Macbook Air 4.2 (2011): Installation of 10.15.4 over 10.16.3 via Patcher 1.3.5 worked: After starting yesterday night I found the installing screen today; after forcing a restart all looks okay.
I will do the iMac9.1 when I can enter my University office again.
Many thanks to the contributors to @dosdude1 and the other contributors.

Bonjour,

I re-installed 10.15.4 with @dosdude1 patcher 1.3.5 over 10.15.4 installed with 1.3.1 patcher (install to this machine for both of them)...

I'll let you know...

Serviteur,
