macOS 10.15 Catalina on Unsupported Macs

[BigSmileMan]

Does anybody know if there is a way for a 13inch 2011 MBP to connect to wifi via the iPhone personal hotspot on the Catalina patcher?

My jackLuke fixes for Bluetooth,airdrop,handoff etc. are working perfectly, but my dosdude1 patched Catalina Mac is unable to connect to the internet using the iPhone’s personal hotspot. I get the prompts, but am unable to seal the deal. Everything that should be turned on normally for this is.

Same on 13inch 2011 MBA. But you can connect if open modem sharing on iPhone and connect to it on your Mac like a wifi hotspot (not personal) dropdown list with password. It will work in this case. So searching for solution too for one-click easy method...

I also got it to work there the other day by connecting my iPhone to the Mac via USB, so apparently there are some work arounds. Thanks also for sharing yours.

Hi all,
after installing latest update on Catalina by dosdude1, my APFS volume is missing.
As I patched the ROM, I should not see the code (yellow and white) on startup.
I can see some APFS volumes on startup, when clicking ALT key, but not on control panel as you see on enclosed pic.

Any help?

I mean you can connect your Mac to iPhone over WIFI for internet usage. But not literally by Personal hotspot message as in your past message. Same error I have too. But if you open on iPhone Settings->Personal hotspot->Allow others to Join and stay on that page, and after go to wifi list on a MacBook you will see in a couple of seconds your phone become like regular (ad-hoc) wifi hotspot (NOT in modem mode section as it was before). Connect and use it.
Tested now. It works. I think problem related to bluetooth account authorization bug. But I'm not so skilled in troubleshooting that
Sorry my English not good enough

your English is great! I got this to work one time, but only once unfortunately. It doesn’t seem to work every time.

I don't know which WiFi module you've got installed. My 8,1 had WiFi issues after a couple of updates, until I started manually to check the Broadcom post-install patch, which wasn't suggested for the 8,1. Maybe that would be worth a try...

Hello Makra tried that a few times (reload patches w/Broadcomm43.xx) alone or with all patches and with 10.15.7.02 OS reinstall. No go :-(. A work-around, currently using my 5G iPhone or 4G portable modem via USB. (No current LAN access). Holding off for now on a reformat of SDD and clean install as MBP to perhaps solve issue needed daily for work.... otherwise everything else works flawlessly.

Hey guys, first of all sorry for any following mistakes as I am not really into macs at all.

I wanted to try my hand at upgrading relatives 2008 iMac 8.1 to MacOS Catalina using Catalina Patcher and everything was going just like it should until last stage where after choosing disk for installation and first stage of it, which all went as it should, mac rebooted, again as it should, but then after a bit of loading, instead of doing it all the way, screen goes grey and it goes back to MacOS Utilities at which point I have no idea what to do since drive is not bootable at that point.

Thanks in advance.

Trying to install this on my Mac Pro (Mid 2010) and I'm having issues. I downloaded the software from DosDude, downloaded the latest version of through the macOS Catalina Patcher onto a thumb drive. It boots from the thumb drive but when I try to install I keep getting the message "This copy of the Install MacOs Catalina application is damaged, and can't be used to install MacOS." Has anyone been through this before and are there any workarounds? Thank you in advance!

This error is so famous - even @dosdude1 himself made a comment in his own online documentation about it. Try to find it.

What GPU do you have installed? Have you ever checked this thread or this tool?
Using a metal GPU you would not need this patcher.

Yes, it happened to me as well recently when I tried to reinstall dosdude1-Catalina. Luckily I have another bootable installation app on another external disk partition which was created in earlier this year when I installed dd1-Catalina at the 1st time. My suggestion is to use another USB stick (16GB), or use an external disk and create a 16GB FAT32/DOS partition.

I have the The HD 7950 Mac Edition which according to the specs is metal compatible. I will look in the docs to see if I can find DosDude's comments.

I just tried this and got the same message. Though I formatted the 16GB partition in MAC OS Journaled. FAT32/DOS didn't seem to work in Disk Utility, unless I'm doing something wrong, which is possible!

You do not need this @dosdude1 patcher, you do not need any patcher when using OpenCore. There is a self made solution on the thread I already mentioned and there is a ready to fly tool called OCLP.

Take a look at my signature, I own some iMacs 2009-2011 modded with a metal GPU - this alone opens the gate to get around any weird patching.

It may not be important for the type of partition because it would be erased again during installation of the bootable installation app.
Have a look of https://github.com/dosdude1/macos-catalina-patcher/issues/20, which may be helpful.

And as @Ausdauersportler said just before: You may use OCLP instead. I am using OCLP for Catalina as well.

Boot to a recovery partition and run csrutil -disable. Even if it shows SIP is disabled, run the command anyways and reboot to try installing again. There’s something about Catalina and SIP.

Gotta quote this so it doesn't get burried.

did you create a USB installer for the installation? Was the imac 8,1 running El Capitan before you tried to install Catalina? Did you follow the dosdude1 tutorial on YouTube?

I created installation on external hard drive, I followed dosdude1's turorial step by step. But when it comes to previous macos it was snow leopard.

I Just prefer Mojave to Catalina, which booted and ran very good on the MBAir 2010.
lately i have been staring at a iMac 2013 just to run more Mojave.

Others here will probably be able to advise you better than me, but this is what I would do if I were you:

1) First upgrade this computer to El Capitan and do all the security updates you can on El Capitan. This is so your device can get all the firmware updates that it needs . Take the device as far as it can go on El Capitan. Even on a supported Mac, you cannot go straight from Snow Leopard or Lion to Catalina— you have to make some pitstops in between so your computer gets the necessary firmware updates. In your case, If you are starting on Snow Leopard, You might need to go to Lion or Mountain Lion first and then jump to El Capitan. You can find out information about the “OS jumps” that you can make on Apple‘s website. Firstly, You need to upgrade this device as far as it can go, before using DosDude1’s Catalina. The Dosdude1 demonstration video on YouTube is taking an unsupported Mac from El Capitan to Catalina….

2) make a Catalina install usb stick like dosdude1 advises.

3) if you want to install a dosdude1 Catalina on an external HDD, it may be possible, but it will probably be extremely slow And not so much fun to use. Catalina was designed with SSDs in mind. So if you’d like the computer to be comfortable to use, After you upgrade to El Capitan, and after you’ve made the dosdude1 USB stick, you can install Catalina on an external SSD or Swap the iMac’s internal HDD for an SSD. With an iMac 8,1, an internal SSD would probably yield the best results. You can find a 2.5 inch SATA SSD For that iMac for relatively cheap. while we’re on the topic of the internals, you should max out the ram for this iMac before taking it to Catalina also. Catalina requires at least 4 GB of RAM, your iMac can take up to 6 GB(unofficially), I believe. Maxed out ram and an SSD will give you the best results with dosdude1 Catalina.

RE: follow-up on WiFI keeps disconnecting on able to turn on (Post #14,791 )

Hello All,
Just briefly. Found the problem. A defective USB bluetooth 4.0 (that finally went dead) used for continuity and better BT connections with accessories. The USB BT was creating a "short" that would cause the BT/WiFI card WiFi mode to disconnect. Since discarded BT, WiFi works like a charm. Will buy another BT 4.0

Have patched with DosDude's Catalina Patcher 1.4.4 and applied all recommended patches for an iMac 11,1.

Activity Monitor reports that there has been and is no use of the GPU. This is despite running a lot of graphics intensive tasks. Does the Catalina Patcher prevent Activity Monitor seeing GPU activity ?

I tried to run LuxMark to check the GPU. LuxMark reported that my GPU had OpenCL v1.2. But found "Device OpenCL version: OpenCL 1.0". LuxMark then crashed. How can an HD4850 report OpenCL v1.0 AND v1.2 ?
