macOS 10.15 Catalina on Unsupported Macs

[Larsvonhier]

Where is it possible to allow this?

First, check if you have set the "amfi_get_out_of_my_way=1" param in your nvram boot-args.
If already set, you´d have to self-sign the apps that crash due to wrong certificates.
You can easily google that or find it here in the thread how to do that - first step is to create your personal certificate in keychain, then use terminal cmd to apply that to each app that crashes. Has to be redone for updates of the apps, though.

Sorry for asking a probably fairly stupid question...

I want to install the 10.15.6 update thru Dosdude's Catalina patcher. Do I need to do a fresh install? As far as I know, there is no possibility to install "just the updates".

Thanks.
Willem

The „install fresh“ option to a volume with an existing macOS will update it without deleting user settings or apps...
Just use the freshly prepared USB installer stick.

Hi. Anybody with macOS 10.15.5 and OpenCore 0.5.7 have tried to upgrade to 10.15.6?

 

[Dilli]

Yes the Catalina Patcher will download 10.15.6 create a new Catalina Patcher usb and install over 10.15.4 2. I never tried installing over a usbOpenCoreAPFSloader do unsure it would cause issue I just erase mine 3. Yes you can install on a ssd but depends on your Mac if you have a metal supported GPU you will have graphics acceleration if not none and possibly issues with legacy usb if you do have a metal supported gpu WiFi is not working and sound out of the box both are fixable 3 people have methods of installing Big Sur parrotgeek, Barry and iPixelGalaxy and he has a video giving instructions to installing and getting WiFi working and help to prevent the volume from being sealed so you can make changes as Big Sur boots from a snapshot

Yes my imac 2011 has upgraded metal card but my macbook air 2011 has legacy intel gpu. Do I need to tick, untick any thing while applying the dosdude patch. i will check on big sur issue of wifi and sound. Tks for the tips ?

I have a Mojave install on my 5,1 Mac Pro that is finally ready to move to Catalina. I downloaded the patcher and used it to download Catalina (looks to be 10.15.6). The USB stick I created will not work. It says the installer is damaged. Seeing the FAQ on dosdude’s site, I redownloaded everything and tried again with the same result. I even then tried downloading Catalina with a supported machine with no luck. Seeing how many of you that got 10.15.6 working, it makes me wonder if I am doing something wrong. I even tried installing on a fresh drive.

Urgent hint: Try using another USB stick or drive for the installer. We had that issue a (felt) quadrillion times here with Mojave and Catalina.

On 2nd thought: Does the 5,1 really need the patched installer? Imho all you need to set is the NVRAM boot arg "-no_compat_check" and then you should be fine with the Apple vanilla installer w/o any patches...

Why not just wait for Dosdude1's magic patcher ?

Without the update - Still a working system

Anything go wrong with the update - Could be an unusable system

Just my 2 cents

Agree with you.
As a normal user, without any knowledge of coding, what I always do is waiting for Dosdude patcher.
This is the case with Big Sur now
But I like to follow all postings here from these bunch of expert young guys, even if I don't understand the contents of 90% of the posts!
I really enjoy their efforts and deeply thank them all for the hard job

No I would not apply any patches and see if you you can get into the desktop the one you won't need to check is the legacy video patch

Having trouble updating Catalina .5 to .6 using my unmodified VM technique (Parallels). Background: my flashed 4,1 has been able to run Catalina unmodified from the start just by having a few hardware upgrades (Metal card, wifi-ac/bt4.2 card) with the only issue being initial install and upgrades. For those, I have used a VM on a secondary 10.13 drive to boot my normal drive on USB, where it's more than happy to install/update normally until now.

What works fine:
Updating VMs that boot from a virtual disk

What isn't working:
Updating a VM that boots from a real disk, connected via USB (hands off the native device to the VM)

Any time I try to update the VM booting from a real disk, it just boots back into Catalina .5 without running the update.

What I've tried:
Update via System Preferences, Update via installed Combo Update, Install over top via created media by booting to installer, Install via created media by running the installer on Cat

In each case, they all succeed at the first step (setting up the system update/install), but once they reboot, the progress bar just ends in a standard login prompt for .5. I've also kicked Parallels into an EFI boot menu, tried booting different devices, and even went to the EFI shell, tried booting boot.efi from "macOS Install Data/Locked Files/Boot Files/boot.efi", which in the past has been the last resort saving grace. In that instance, it tried to continue, but a text screen then shows some cryptic boot errors, CPU use for a couple minutes, and then total idle.

My guess is that .6 (and maybe Big Sur, I dunno, have to wait for PB) has changed some of its booting mode, and Parallels would need an update to support it. But figured I should ask here, in case anyone has any better experience or suggestions (other than using a modified installer, which I'm not ready to do)

Goal of course is to have this working before I try upgrading my main OS using the same method. I've been testing on a separate throw-away install before I try the real thing.

Cheers.

Edit: I tried it on my main boot disk, and it miraculously worked. My test drive must have some issue. All good.

After upgrading to 10.14.6 I am suddenly seeing BlueTooth disconnects and keyboard madness (switch to bad characters) on my MacPro 5,1 upgraded with a Broadcom BCM94352HMB. After a bunch of trouble some years ago this has been rock solid.

Tried resetting BLE and waiting for results. Noticed the Debug menu appears gone.

 

[Ramonsterrr1981]

Kinda sucks that the recommended BT dongle doesn’t work anymore.

I even managed to update to 10.15.6 without any issues and Airdrop working.

Even with the new Bluetooth file, no dice.

thanks for all your help, if you can help fix it, great, otherwise no continuity.

I have a MacBook Pro 8,1 with a Bluetooth ASUS BT 4.0 dongle (which has a Broadcom BCM20702A1 chip).

Here is what system report says:

View attachment 934341 View attachment 934344

AirDrop in Finder works 100% with both older Macs and new and my iPhone 11 Pro.

In older versions of macOS this ASUS BT-400 dongle was recommended for using Continuity Activation Tool. Obviously that doesn't work on Catalina anymore, which is when I found your great work.

Thanks for all your help!

Is it possible run this with only 4 gigs of ram on a macbook 5.2
I am already on Mojave if that helps.

If you have AirDrop on Catalina Finder, applied the catalinacontinuity fix and replaced the Bluetooth file, then try to plug with an USB cable your iOS device to the Catalina Mac, then from Catalina Finder select it and click Trust, after from the iOS device tap Authorize .

If still for example handoff is not working, then try from Catalina System Preferences to sign-out from your Apple ID , reboot and then sign-in again, your iOS device and Catalina Mac must use the same Apple ID (iCloud account), and I guess you need also the iCloud 2FA two factor authentication enabled.

Hi! Since i installed catalina with the holy patcher on my good old mac pro 3.1 i cannot install windows on another hard disk no more. I'm not talking about bootcamp, i know it's kinda broken, i cannot even boot an usb windows 10 installer. Did the patcher modified bootrom in some way to support APFS? is it possibile to revert? I need a windows dual boot and virtual machine isn't a viable option. Thanks.

It shouldn't. Take your Catalina disk out of the machine and try to install Windows without Catalina disk present, however it should be safe using bootcamp to install windows to another internal disk

This happened to me when I initially put 10.15.4 on. I found the following Terminal Command to run in this Thread and it fixed it for me

sudo nvram boot-args=amfi_get_out_of_my_way=0x1

Thanks a lot for very timely help! It really works after restart! ?

I think you need to reboot after each Edge update ?‍♂️

Also works! Thank you!

Bonjour,

Since 1 am hour, I no longer had internet at home (it came back 10 minutes ago), so I shared the connection in 4G+ to Wifi, my wife's Mac (a 2015 iMac) refused to this connect with his Redmi note 7, but also from my Samsung SM-G935F.

Until then you say to yourself but what is he talking about, this Mac is not one of the unsupported, well just to tell you that I installed the Dosdude Wifi patch and that it solved the problem. problem, it seemed to me an original adventure (and at the same time disappointing on the part of Apple) to tell you.

Have a good day. ?

I answer myself: yes, it works directly without any other trick.

Yet another success via Patcher 1.4.4 by USB over 10.15.5supp. Total install effort took less than 1 hour w/ no drama, dot 6 uses a tad less overhead than dot5supp. This is the 7th iteration of Catalina on this Mini3,1 via dosdude1 patchers which have become very reliable.

@dosdude1 has changed the default selection of patches with the 12,1 and 12,2 2011 iMacs. The legacy video patch will not be installed by default, in case you need it, you may boot into the patched installer later and do a manual selection of this or other patches.

You can even choose this new "install to this computer" mode without creating the bootable USB installer. Just download the patcher and new installer, fire up the patcher an follow the instructions on screen.

This does NOT work with the late 2009 and mid 2010 iMacs, here the legacy patch will be selected per default. You will not try to roll back the patches . Of course creating a snapshot is always a good idea before starting the patching.
