I was having a problem getting the correct download from Apple using the patcher, but then the download appeared in my downloads folder when it had not been there previously. I have seen this download behavior many times using Catalina beta. In this case, I made a video showing what I thought was a problem with the patcher's download process, when suddenly the Catalina installer appeared in my downloads folder.

This video does not prove what happened, because I cut the video off then started a new one, appended to the end of the first video, to make what you can see here.

Have you seen downloads in Catalina act this way? Video runs 3:55 at normal speed.


A problem appeared with a download using the Catalina version of macOS, then the problem cleared up. I have seen this download trickeriness many times. Downloads do not always appear immediately in the downloads folder in finder yourusername/downloads,

but rather, the downloads appear immediately in
/System/Volumes/Data/Users/yourusername/downloads (through command line)
/System/Volumes/bootablevolumename/Users/yourusername/downloads (through Finder)
It is weird, the path using the command line is not the same as the path using Finder. Regardless of which way you go to this directory, there are times when its contents does not match what Finder shows through yourusername/downloads

Those paths seem to be alternatives routes to the same location, but sometimes, there are differences between their contents. In this video, I thought I was getting the wrong download through an app, until after I made a video showing the problem, the correct download appeared.

Have you seen this happen on Catalina?

Any ideas what is going on here or how to find out?

The issue here is the detection method Catalina Patcher uses to see if a Catalina Installer already exists... It's taking into account beta installer applications as well. The "macOSDownload" folder that you see when performing the download is just the temporary location where Catalina Patcher stores the downloaded files. Once the download fully completes, it will compile all that into the proper installer app, and then get rid of that folder.

I am writing now the catalina operating system to an external usb drive following the instructions of dosdude1's video.
Can I install it over my existing apfs/mojave system without erasing everything (and so loosing all my apps and settings) using the reinstall macos option, after booting from the usb drive?(like I did with mojave over the previous version?)
Thank you!

Yes, you can. If you want to do an upgrade, just install onto that volume without erasing it.

I am a little confused. is Catalina just work with APFS drive? My Mojave drive is HFS+ and I create a new installer with @dosdude1 latest Catalina patcher and boot it. I don't want to make a clean install and I choose to install as a new copy but when I choose my Mojave drive it saying this drive is not formatted APFS? How can I install Catalina to my drive without formatting?

Edit: @dosdude1 tutorial video helped. Thank you.

I appreciate your help and am sorry for having to ask a follow up question. I got the auto patcher plist from your previous post and moved it to the correct location, but when downloading the bluesky.sh patch, it only downloads that patch and not the HIToolbox or the skylight patches. Where do I find those individual patches to move into the framework folder? I have tried searching and looking on GIT and didn't find them. Also, where do I then put the Bluesky.sh patch? does it go in the same folder as skylight? Thank you for your help.

@FilthyMuppetInnuendo I have a MacBookPro5,3 (2009), and iBook Author works fine on my computer running Catalina, so I don't see why it wouldn't work on the Mac 2009 as well.

Hey, thanks for the reply! It has been so long that I don’t remember some of the intricacies of what happened back then. I know the GT120 was just a rebranded card from an older line, but I don’t know which card. WAS it a rebranded 9400M? If so, you’re likely right. I’ll give it a go.

Just like I anticipated, MacBook5,1 is downloading Catalina final straight from the App Store.

You should be able to power up your computer while holding OPTION-COMMAND-R keys. This brings you into web-based recovery mode so you can unmount your master drive using diskutil from the displayed menu. Once it is unmounted, you can select the Convert to APFS. When I used that procedure, it converted without destroying the data on my drive.

I c a n n o t update from DP8 via „install to this machine“, there is no button to proceed after the patched installer has been created into \tmp.
only „Quit“ and „Back“.
Advice, anyone?

Successfully updated to the full release using dosdude 1.1.6 patcher.

However I notice the following:
1. Feedback assistance is still there and mentions beta??
2. SIP protection is in 'unknown' status and I cannot seem to change when I enable it via the Recovery partition.

Any word on why Auto Appearance is not functioning? Using a Mac mini 5,1. Thanks.

The non-Metal acceleration patches involve using SkyLight/CoreDisplay from Mojave. That feature didn't exist in Mojave, so it doesn't work when those frameworks are replaced.

I never worked on re-implementing it in the wrappers, since there are a couple third-party apps and scripts that achieve the same thing.

Yes, I specifically designed Catalina Patcher to work on both unsupported and supported systems. Installing on a natively supported machine will completely skip the post-install patching stage.

It's having an issue remounting the volume after restore. Try just doing a reboot of your machine, and try the process again.

Thank you for your reply. I have tried restarting and this did not resolve my problem. I also tried downloading Catalina Patcher and macOS Catalina again and it also did not resolve my problem. It still throws the same error message.

Do you have any other ideas?

Yep, still doesn’t work. Thanks for checking, but it was to no avail. I’ll have to do a clean reinstallation of High Sierra… goddamn, that’s going to be hard now that I can’t download it anymore… and manually restore all of my files to their proper locations. Again. Just like with Mojave. Apple doesn’t seem to give a **** about nVidia’s third party drivers, no one seems to have cracked them to shove into Catalina, and I can’t afford a new Mac.

Thanks anyway.

If you installed any of the post install patches SIP needs to be kept disabled

I am experiencing an issue with creating an install disk. I am using Patcher 1.1.6 and I used it to download macOS 10.15 this afternoon. My USB disk is formatted with Mac OS Extended (Journaled) and has sufficient space (32 GB). Attached is a screenshot and the log.

NO, it does not, at least on my MBP4,1. It creates the patched installer into a \tmp. Then only gives you buttons to ress': Quit and Back. So, what are we to do at this point? Thanks for clarification, how did you proceed from there?

It should launch the installer app for you. If for some reason it doesn't, you can launch it manually from the /tmp directory.
