macOS 10.15 Catalina on Unsupported Macs

[telepati]

From the output you are using the "LibraryValidationDisablerPatch", to try fixing the Music app crash, you should delete this "DisableLibraryValidation.kext" from these paths:

/Library/Extensions/
/System/Library/Extensions/
/EFI/OC/Kexts/

In my opencore customised versions it is not included, so that's not the issue.

But isn't that weird? I didn't install this patch.

Any ideas/suggestions with this? It happens with Catalina and on Mojave too:

• Everything works great but I noticed this odd behaviour: when I open a Pages file, it crashes whenever a "smart annotations" that i did on my iPad appears on screen. It just freezes Pages. It's the only thing that bothers me since I do quite a lot of this handwriting. If I hide the smart annotations I can see all the pages on the document normally and work. Naturally, this is not the best since I cannot edit them. Also, if even one small annotation is on the first page, the file does not even open.

And a little doubt: I have just 1.40GB free of a total 8GB RAM. While on High Sierra I would normally have between 2 and 4 GB. Is Mojave/Catalina more intense on memory or is there something I can do to balance this? Could it be this the normal way macOS deals with RAM now? Otherwise everything is normal, the system is working great and snappy.

You could try running the Activity Monitor to find out what is using the memory then at the clog wheel at the top run system diagnostics that will smooth things out and you could find a free memory clean app in the App Store to

No, because it's required if you have a non-metal GPU.

Check from catalina terminal this: kextstat | grep -v com.apple

if you have DisableLibraryValidation.kext loaded then you should delete it.

If you tried to re-codesign Music.app then it won't work more, you should retrieve a stock apple codesigned Music.app or re-install Catalina.

Codesigning works only for third party app as: Chrome, Office and some other.

If you have a Metal GPU you can delete also this: com.apple.security.libraryvalidation.plist

From a Catalina terminal: date -r /System/Library/CoreServices/boot.efi

if the result is different from: 6 Apr 2020
(I assume that date because it's the stock apple boot.efi for 10.15.4 build 19E287)

then you can delete SIPManager.kext from Catalina LE or SLE .

BTW I delete DisableLibraryValidation.kext and everything works now. Even 1Password. Actually all apps worked when I start the machine and try 1Password and it gives a code sing error. But when I open Extension from Firefox and 1Password stopped giving a Code Sign error and starts work. Now no Codesign Error all apps working even Music.app just like you said and iCloud sync of 1Password.

Some apps just crash at first launch, on the second launch they work without issues until a restart or logout, if you codesign the crashing apps they work also at first launch.

But I don't advise to codesign apple stock apps, only third parties if anything.

This kextstat return is from 10.15.4 (19E287)

I removed an entry that was left over from an app installed long ago.

Is anything here unneeded on my cMP 5,1 that should/could be removed. Is SIPManager.kext still needed/used on current install?

Hello everybody, I have a macbook 5.1 with catalina 10.15.4 patched and works perfectly. At the moment the main issue I have is the fact that it didn't recognise any cd, both data and audio. Actually my superdrive is connected with a usb cable as I put a second hard disk instead of it. I tried the superdrive with a win 10 pc and it works perfectly so I don't understand what to do. It works with dvd but only using VLC while the internal dvd player crashes. Any suggestion? Thank you all in advance

I guess simply the "OTA swu fix" hasn't applied correctly, or a re-downloaded package has cleared the dist file patch or mismatched the "macOS Install Data" folder, so before retry, remove these folders:

/Volumes/Catalina Data/macOS Install Data
/Volumes/Catalina Data/Library/Updates/anysubfolder
(you have to mount "Catalina Data" volume from DiskUtility)

generic "Catalina" is intended your disk label

next time during OTA downloading, try instead this script: catalinaswufix5amfi.command
(essentially the same script is contained also in the CatalinaOTAswufix.app)

If also this won't work in showing the hidden "macOS Installer", then you should try the opencore version that install internally to the disk: OpenCoreAPFSloaderupdate.app.zip

10.15.5b4 running fine now on MBP5,2.
Thank you jackluke, and sorry for the noise. Stupid me, I must have forgotten to run CatalinaOTAswufix.app the 2nd time to do the OTA update fix.
So simply made up for that now, without redoing the download of the beta4. Then the other usual steps (start install, OpenCore boot into OTA phase 2, post-install patches 1.4.3, NightShift re-install with patch updater).

10.15.4 has been running fine since day one. Now suddenly it seems to have an extra instance of Dock loading, and it won't restart. One Dock will slide down, and the top menubar goes away, but a second copy of the dock is hiding behind the first one, and it stays static on the desktop. Restart and booting into another ver of macOS is blocked. I have to force power-off in order to shutdown at this point.

The it reboots right back to 10.15.4 on restart to the same issue. The os works well, but won't let me restart.

When I check the Activity Monitor, there are 3 entries for the Dock. When I do finally get into Mojave after an NVRAM reset, there are only 2 entries related to the Dock. I'm pretty sure this is the cause, and I only noticed it after using Onyx to run the launch services cleanup / Maintenance Scripts.

So, I'm about to boot to a patched USB stick, reinstall from scratch (which I hate), and see what happens.

Unless someone here has an alternate solution.

cMP 5,1 - Fully updated w/RX-580, Wi-Fi AC/BT4LE, 48GB mem, etc... etc... Firmware 144.0.0.0.0

 

[crjackson2134]

So, it seems I did something wrong here...

I erased my Catalina container (leaving the DATA) and reinstalled Catalina clean from the patcher.

This fixed my problem, now it doesn't have the extra instance of the dock and works correctly. However all the apps and data didn't get picked up from the DATA container. Everything is there still, just doesn't show up normally in the regular locations. Launchpad shows none of the apps, documents from finder shows none of the documents.

So I told it to migrate everything from the DATA container and it did, now everything is there, BUT ... Now I have all the stuff on the DATA container duplicated to the macOS container. I don't want duplicate copies. Can I safely just delete everything from the DATA container now? How does that work?

The same here, only when I shut down, it actually shuts down. Similar config to yours only difference is I have wifi ac and BT4 via usb dongles. However, it had the same dock behaviour before installing the dongles.

A clean install fixed it, now I have the problem of all the duplication of data. I guess if no one here chimes in soon with an answer, I'll have to erase the whole drive with both containers and start over again.

I'm hoping someone will jump in with an easier solution.

UPDATE:

Okay, so here's what happens...

When you delete the OS container but leave the DATA container, the new install creates a second DATA container for the Home Folder and enclosed files. It thinks the old DATA container is a different container unrelated to the OS install.

After migrating the old DATA container to the new DATA container, I opened up the DU and simply deleted the old DATA container.

This reclaimed the wasted space, and didn't have any effect on the newly made install. So I guess it's all good now aside from reorganizing my LauncPad folders.

After all this ... The extra Dock is back again. If someone would please sound-off on any clue how to fix this. I think it happened after migrating the old DATA drive again. I'll hate it if I have to wipe the thing clean and reinstall each app one at a time to fix this.

There must be an answer that doesn't require another clean install...

I am not an expert but I think that a "half pregnant" approach is not going to work very well with Catalina. You were meant to erase Catalina and Catalina-Data at the same time.

Hi as I have the MB 5.1, my system says that I have a generic ache controller, I'm not sure I can use this patch because the guy is stressing out the fact that it should be an Intel controller. How can i be sure I can do it? Thanks

Your MacBook has MCP79 NVIDIA chipset. So it is a game of Russian Roulette for your Mac. My MacBook5,1 was successful in this game. You can't be sure, that's the point. Nobody is going to give you guarantee. Greg in the video decided against it on his world's fastest MacBook5,1.

Don’t. I did this on my MacBook5,2. Don’t recommend doing it. Thankfully @Larsvonhier saved it with his micro-soldiering skills

With Catalina the MCP79 shows as GENERIC but in Mojave the MCP79 is displayed accurately. A few weeks back I bricked a MCP79 Mini. Upon consulting dosdude1, he advised NOT using his APFS ROM Patcher on MCP79 Macs. I quit the patcher after 43 minutes, had I waited a few more minutes, it may have successfully completed the patching process? An "SOS" Mac is the result.

Actually it did work exactly the same as any other data migration, I just had to remove the extra data container.

Sadly, it seems to have to migrated the extra dock issue back as well, so I’ll have to blow it all away again, and start fresh probably. It did seem to fix my rebooting issue from what I can tell so far. That was the primary problem.

I have now figured out how to get rid of the extra dock and external extra dock. So that's done too...
I'll probably do a totally clean install (without any migration, only coping data files) and config as soon as the next point release is finished. What I have now is working fine so I'll POSSIBLY just leave this alone until the next update.

can any moderators answer any of the questions i have posted? i'm trying to sort out an upgrade for my imac 2010 thanks!

Hopefully one day they will write a patch also for this chipset...

I would, but because I deleted a system file and don't really know it's purpose, I'd rather not post it until I'm very sure there aren't any adverse effects.
