macOS 10.15 Catalina on Unsupported Macs

[roysterdoyster]

MBP4,1 17" (Early 2008) successfully updated to 19H1208.
I can't state if advanced network features, screen sharing, etc. work/don't work, as I'm not using them.
Else, machine is running flawlessly on the latest Sec. Update 003 resulting in 19H1208.

Hello All,
Installed 19H1030 with Jackluke CatalinaOTAswufix and DosDude Patcher 1.44 on MBP 8,2. All works well. Showing now another beta update available slightly larger file size (1.42GB): "macOS Catalina Security Update Developer Beta 2021-003 10.15.7". Is this post-update? If so has any one installed? Thanks.

The two features you didn't check may not function. File Sharing via SMB and Screen Sharing. See Post #14033, 2nd paragraph for description.

so, I've never used screen sharing. I'm experimenting now for fun. the SMB file sharing seems to be working just fine for me. I've connected from Mac to PC and from PC to Mac, maybe I'm missing something??

Try to connect to another Mac With File Sharing? Does Screen Sharing ever connect? These features were definitely broken a few days ago with 19H1208.

Build 19H1208 aka macOS Catalina Security Update Developer Beta 2021-003 10.15.7 had definite issues a few days ago see #14033.

Hi to all!
Long long time ago I bought a mac pro 3.1 which I upgraded with AMD 7950 card some time later on. The card never had a booting screen but was running MacOS Sierra fine.
Last week I decided to upgrade to Mojave, then Catalina. I used the dosdude1 patches but unfortunately both operating systems failed to see 7950 (no kexts loaded). I've to say that Catalina patched boot installation sees perfectly the 7950, as well as Linux, Windows! I don't undestand what is the problem. Tried to re-patch the card by patching the original .rom found based on SN number, with no luck.
Could someone guide me what should I do?

Hey all, running the H1208 on my MacBook late 2008 unibody 13" without any issues. I think this old MacBook is almost as much a tank as my grand daughters' 2012 MacBook Pro 13"

Thanks to both posters with the same advice. So simple, duh. I have 19H2. Is that the latest version? Thanks.

The current full-installer is 19H15, get it directly from Apple with gibMacOS-master using the two shell scripts. <attached> Once the 19H15 macOS installer is built, a new v.1.4.4 USB patcher can be made. The current official release is 19H1030, avail. only on Software Update.

Sad to say, I need help with this. I have no idea what to do with the attached file. I have always used dosdude's patch to simply download the "latest" OS version and make the USB installer drive. Anything more is foreign at this point. But I am up for learning alternative methods.

I'll try to help. If you downloaded the file K two attached, you can open it( you'll probably get the security nag so you'll have to go to system properties, security, open anyway) once it's open, double click on gibMacOS.command ( i think you get the nag again) That will populate a list of installers you can download from apple. I believe the newest Catilina installer 19H15 was number 5. at the bottem enter the number you want to download. the installer will be saved in the Mac Download folder that's in the gibMacOS-master folder. I personally dragged the Catalina installer to my desktop, then opened dosdudes patcher program and let it do it's thing. once you get the 19H15 installed, you can start the update can of worms. i Hope i'm steering you right

Updated my MBP5,2 to 19H524.
OTA from H512. Like in post #13,564 but to internal SSD this time, so there was no need for the OC step.

Updated MBP5,2 to 19H1030, OTA from H524. Same procedure as in referenced posts.
All fine.

Catalina is still my production system.
I don't experiment with betas for it in future, but am using more and more BigSur (11.3 with patcher OCLP 0.1.1) which offers graphics acceleration (beta version, in very usable shape for Nvidia 9600M GT).
I've set up some rsyncs to keep the essential user data of Cat and BS in sync.

Big thanks to ASentientBot who made this possible for Cat, and now again for BS!

Welcome - From the unzipped gibMacOS-master ƒ in your Downloads ƒ, run the gibMacOS.command shell, go to the Security Pref Pane and OK it, enter the #5 in the prompt below. Then make certain the D/L has fully completed, progress is shown, it can take awhile. Inside the new Downloads ƒ is a ƒ with a Product I.D. #, drop that ƒ into the BuildmacOSInstallApp.command shell, after another visit to the Security Pane and OK, a brand new full macOS Catalina installer v.15.7.03 aka (19H15) will appear in the gibMacOS-master ƒ. It can be selected from there when building the new v.1.4.4 USB patcher. BTW - ƒ is for the word - folder - because I'm lazy. 😎

I think at this point I just want to blow this entire hack away and put Yosemite back on it to sell. How hard would that be?

You can use Internet macOS Recovery and wipe it back to the OS version it shipped with.

From Build 19H1024 another smooth update w/CatalinaOTAswufix.app, boot OPENCORE3b1 to see MacOS installer, re-install recommended v.1.4.4 patch set, Force Rebuild Caches, restart, temporarily opt-out of Beta updates to avoid the dreaded SU 2021-003 Beta, update X-Protect to 2145 and MRT to 1.78 w/SilentKnight, update Validation Patch via Patch Updater, restart. Build 19H1030 runs surprisingly nimble on this very early Mini3,1. 😎

 

[psu7276]

Thanks to both Resurrector66 and K Two for your guidance using Terminal to get the Install Disk I needed. Everything updated flawlessly.

Hi,
macbook pro 4,1: OTA fix enabled, Catalina 19H524; when searching for os updates I cannot see the stable 19H1030.
What I see it's:
- Beta version for developers security update 2021-002 for macOS Catalina (10.15.7) (1,39 GB)
- Safari 14.1 Seed 4 (93,5 MB)
- Safari 14.1 Seed 4 (93,5 MB)

Anyone experiencing the same issue?

...and why 2 same entries for safari?

Thanks

UPDATE: no issue, I tried with the beta, instantly my mac asked to reboot and failed with a message impossible to install updates, then the software update panel refreshed and the stable security update showed

Also another smooth update for my 27" iMac 2010 with CatalinaOTAswufix.app.

There is no need to re-apply DOSDude's Catalina Patcher after the update since I boot from OCLP 0.1.1 on an SD card.

All work with no issue, including sleep & DRM for Apple TV+ channel.

EDIT:
If you boot with OCLP your do not need any additional tool to update your system, just set use the moderate spoofing when generating the EFI.

Mojave, Catalina and Big Sur can be installed on your iMac natively using the original (unpatched) Apple macOS installer and updates are available as on a completely supported system.

(all this is true for Metal GPU modded iMacs Late 2009 to Mid 2011)

I can't seem to get it to go to Internet Recovery. And evidently there's not a regular recovery partition anymore either.

I am having an issue using my RX580 again. I put a new HDD in (cloned) and it wouldn't boot. Now, using the old non-metal GPU, I went through the screens and used the patch tool to post-install it again. However, I am just using my old non-metal GPU anymore, and when I remove it, it doesn't switch to the 580. How can I use the metal card? Can I set it up to use both? (As in boot screen support with the GT120 and the metal card for MacOS?

Does clamshell-closed mode work with this OS? Does it work at all with MacBookPro5,5?

I couldn't get it to work with my MacBookPro5,5 running Catalina.

Shut-down the Mac. Wait 30 seconds, hold down the ⌘-option/alt-R keys, start the Mac. Often it takes a while for Internet macOS Recovery to respond, be patient. macOS Recovery can be re-installed by the v.1.4.4 USB patcher, it's near the bottom of the list of selections.

19H15 can be installed over the dreaded 19H1208 and updated straight to 19H1030, just opt-out of the Beta updates, first. I just did it on the inflicted Mini3,1 and iMac11,2. 😒
