macOS 10.15 Catalina on Unsupported Macs

[makra]

I've updated a MacBook 5,1 from Mojave to Catalina (19H15) with Dosdude1's Patcher. Worked as well as on my 8,1. But CatalinaOTAswufix simply doesn't work - I've tried lots of times. Does it have anything to do with the EFI Shell boot system on a pre-APFS machine? (Would USBOpenCoreAPFSloader3 be, what I ought to understand and use?)

If the BOOT ROM is unpatched in the cMB5,1, you will need USBOpenCoreAPFSloader3 on USB to run the second element of the updater to complete the update install before re-applying the patches from the @dosdude1 USB. 😳 How it works, assuming you now have both USBs. Run CatalinaOTAswufix correctly, start the D/L. It will display a progress bar to about 10% and then reboot, hold the option key and get the Apple boot selector, boot the farthest right USB. You will get a menu, select the # that corresponds to "macOS installer", select the # and the installation will complete into another restart, select the Catalina Patcher USB and re-install the appropriate patches - Force Cache Rebuild - restart, done. None of our MCP79 Macs have patched BOOT ROMs, so this is SOP for our Catalina updates. Works every time. 😎

Works every time. 😎

Right!

Right!

If it doesn't work for you. Delete everything in /Library/Updates ƒ and try, again. 🧐

Sorry, that wasn't clear: Worked very well.

I successfully updated to 19H1323 using the CatalinaOTAswufix.app and USBOpenCoreAPFSloader3.app .Had to run Dosdude1 Patcher, and Silent Knight a couple times to update.Running great so far. I like it.

I regularly clean logs etc. with a lightweight efficient one-trick-pony app called "Startup Disk Full Fixer". The app does an excellent job and never fails. However, I cannot delete one item from the Trash: some content from the folder "com.apple.safari", as Catalina claims "The item is in use". I fire up Activity Monitor, close all Safari-related actives, still am not able to empty the trash.

I tried to boot into Recovery mode, but there is no Recovery disk available.
I understand from the forum, this is supposed to be so on purpose.
I further understand, booting into Recovery mode via Cmd-R wouldn't work anyways, since "csrutil disable" would be in vain, as SIP is disabled via dosdude1's patcher anyways.

That being said: how can I empty the Trash in the above mentioned situation?

Thanks in advance. Maybe K Two knows how to solve this problem?

Use lsof to list all open files. It may tell you what app/process is using the file.
But shouldn't a restart make the app stop using the file? Unless there's an alias that points to the file or to the folder containing the file.
Check the file for permissions and extended attributes.
ls -l@ thefile

ls -l@ thefile

ls -l@ provides an actionable result: com.apple.quarantine
How do I proceed from here?

Thank you so far.

Try killall Finder >restart.

com.apple.quarantine

quarantine shouldn't stop the file from being deleted.
If lsof didn't show the file as open then it should be deletable.

Maybe the file is locked or you don't have permission to delete ? Use ls -l@eOG thefile to show extended attributes, access control lists, flags, and colors .
Use sudo chflags noschg thefile to remove the super user immutable flag.
Use sudo chmod -a "group:everyone deny delete" thefile to remove the "group:everyone deny delete" ACL.
Use sudo xattr -d "com.apple.quarantine" thefile to delete the "com.apple.quarantine" extended attribute.
Use sudo rm thefile to delete the file.

The command did not solve the problem. But Thank you for the tip.

Thank you for your help.
The commands did not enable me to delete the files.

the undeletable files aresubfolders of com.apple.safari/WebkitCache/Version16/..
a folder "Resource" containing 88 files named like this: "00CB66CD54A5634CD7FE9848D513DFE362F831AC"
a folder "Blobs" which is empty
a folder "355839D21ECE8AF844CEB0EF263A62EDAC6D3D6C" also empty
Here are the results delivered by the terminal commands ("the file" replaced by the individual folders and files)

sudo chflags noschg thefile ->no result
sudo chmod -a "group:everyone deny delete" thefile ->chmod: No ACL present 'the file'
sudo xattr -d "com.apple.quarantine" thefile ->xattr: thefile: No such xattr: com.apple.quarantine
sudo rm thefile ->rm: thefile: is a directory

How to proceed? Thanks for your help in advance.

man rm

help page about using the rm command. will give you an idea how to delete a directory

The commands were only examples. the xattr, flags, acls, permissions, etc. may be different for your files.
ls -l@eOG should get all the info.

Did you run First Aid on the partition to make sure the file structure is ok?

To delete a directory, sudo rm -fR thedirectory

Looks like Startup Disk Full Fixer app has become out-of-date. For that kind of app which is updated for each macOS and since Tiger has never messed anything up and actually fixes stuff is Maintenance by Titanium, here: https://www.titanium-software.fr/download/1015/Maintenance.dmg and if you have Onyx it's already in there.

I like both those programs. I also use Cleanmymac X as well. Haven't had any issues with using those if I have a problem.

I have to admit, this is the best Catalina has ever run on my MBP since I started it

 

[upipes]

mac pro 3.1 nvidia gtx 680 Catalina everything perfect

I own a 3.1 too. I'm still with Mojave, but after latest Security Update, I've got some troubles ...
Would you recommend Catalina on a MacPro 3.1 with GTX680 as yours? If you use Final Cut, could you tell me if all is working?
Thank you in advance.

Thank you in advance.

From what I have heard and read the best you can get with Final Cut on more recent macOS versions is using a different GPU (AMD RX 470/480/560/580 and later). These offer 4K HEVC and H.264 hardware acceleration used be more recent versions of Final Cut. From this perpespective it is likely more interesting to get a new GPU before moving on the more recent macOS versions.

Startup Disk Full Fixer has its perks. It never lets down, always works 100%. Onyx is a constant on my maintenance routine, of course.

Thank you for being so kind to look into my problem.

I ran First Aid and Onyx, everything appears to be Ok.

The ls -l@OG command also delivers no info, unfortunately.

Thanks also for the sudo rm -fR command, it wouldn't delete the files, either.

These files are so far impossible to delete, not by force empty trash, not by Onyx.

I thank you very much for your help, joevt

I did not know that those graphics cards are compatible with my MacPro 3,1

Maybe we need to see the results of those commands to suggest next steps. Have you tried booting from a different macOS?
