Well this is nice, Thanks @dosdude1 for the patcher, Catalina works surprisingly well on a machine that will be 10 years old in October. Not to mention only 4 gigs of RAM.

That's awesome. If I am not mistaken on the model and year, I have both an MBP5,5 (like yours) and MBP5,3 (the 15" version). I put on hold the updating of both of those to Catalina since I thought those needed the APFS Patch feature of @dosdude1's macOS Catalina Patcher. Which version (1.0b6 or 1.0b5) did you use to successfully boot to the latest Catalina beta?

Thanks.

EDIT: Sorry, I was mistaken. Yours was late 2009, while mine was mid 2009. I guess I will wait when @dosdude1 will implement his APFS Patch feature on the next version (1.0b7?).

That's a MacBook6,1, which supports High Sierra, and therefore APFS booting, natively. I'll be updating the tool soon with a software APFS-booting implementation for machines that don't support doing so natively, once I get it all worked out.

OK then. Looking forward to it. Thank You!

P.S. I replied to my post that I indeed was mistaken on the model.

MacBook 5,1 Unibody Late 2008 (8Gib+SSD), running Mojave 10.14.5 on HFS+, it does not support APFS boot natively. Is there a way to upgrade it to Catalina without losing data? Or fresh install. I think current available options are for device with native APFS boot, right?

Why doesn´t support boot APFS???

You should use an administrator account for both the scripts.

Maybe you have a Catlaina APFS empty Recovery, could you check from Terminal:

diskutil mount Recovery
open /Volumes/Recovery/

and check inside if there are basesystem files.

Maybe I wasn't clear, sorry about that I was in the administrator account for that. I followed the steps and got this.

Yes, or you can apply this: Mojave VolumeIcons for apple boot manager
[doublepost=1561962152][/doublepost]


The script just needed to integrate or to type before running in Catalina Terminal: sudo mount -uw /

However keep in mind that the "CMD+R" associated to your machine is only the latest macOS installed or re-installed or beta updated.

For example, if on internal disk I have two APFS containers with Mojave and Catalina, and I install/update Catalina, then "CMD+R" Recovery is Catalina, if instead I re-install or update Mojave to its next beta then APFS Recovery becomes the Mojave one.

How can you patch these icons?

macOS Patcher 3.0 beta 3 has now been released. This is the description from the macOS Patcher releases page:

"This is the third beta of macOS Patcher 3.0, the first version of macOS Patcher to support macOS 10.15 Catalina.

Release notes for macOS Patcher beta 3:
  • Add MacBook4,1 installer support
  • Remove NVRAM boot arguments requirement
  • Rework installer implementation

Important notes:
  • This is a beta release of macOS Patcher with support for a beta release of macOS. If you discover an issue, please make sure it’s an issue with macOS Patcher 3.0 and not with macOS 10.15 Catalina. If your issue is with the macOS Patcher 3.0, then contact us on Discord or MacRumors Forums, or create an issue on the macOS Patcher GitHub page.
  • You must use the -legacy-prelinkedkernel flag when creating a patched installer for the MacBoo4,1.

You can read about the removal of the integrated utilities, and the future of macOS Patcher, here."

macOS Patcher 3.0 beta 3 is available here.

Does beta 3 suppport machines that do not support native APFS or not? I see you added MacBook4,1 which do not support APFS so I'm confused.

The beep I don't think is standard on any box. You could try zapping the PRAM or resetting the SMC. I have yet to get a machine to reset the SMC, they are all different. Be careful if you reset the PRAM because if your install is relying on some boot flags, it will wipe them out. But I think Dosdude1 fixed that in his latest series of patchers. I would check first before proceeding.

I reset the PRAM and now it won’t boot!

I can boot from the USB and try a reinstall. Unsure whether or not it’ll be a fix though as I think resetting the PRAM has wiped out the boot flags?

In the Recovery path you have two folders, open them and check inside, then try to delete the empty one, and re-try the recovery script.

Done, still no go but I did get to enter my password this time.

Also, I get weird messages only when I boot into administrator mode, regarding Continuity activation tool. This worked in Mojave and I have never seen these messages before. I include this only because maybe it is related? Somehow?

Could you post a picture of the content of your Recovery (the non-deleted folder) ?

And the result of Catalina Terminal: diskutil apfs list


Instead about Continuity try to run before the script: sudo mount -uw /

Contents of the Recovery folder.

In the interests of adding info, I do have a firmware password set. I press and hold CMD+R to get into recovery mode, I get to the password entry screen, enter my password, then nothing happens and I need to do a hard reboot.

From your pictures the APFS Recovery has been correctly patched, probably the issue is the firmware password that detects a patched Recovery and can't proceed, but for additional fix you may try this from Catalina Terminal:
diskutil apfs updatePreboot disk2s5

What needs fixing that the above command will fix?

Anyway to get rid of the firmware password? Will booting to the install USB give me a way to do that?

Also, thank you for all your help, I really do appreciate it.

That command adjust the APFS preboot container to point each element correctly, for disable a firmware password from a USB Installer or recovery in Utility tab there is the Firmware Password Utility , but I don't think you can use it from the USB Catalina Installer, probably you need to use a older one.

Anyway an APFS Recovery can take up to 3-5 minutes to boot, so try to wait that time frame.

And instead to fix it now, maybe wait first for Catalina beta 3 release.
