Note:

Before anyone asks again, Catalina is not supported (actively blocked) on a MP5,1:

What file has the unsupportedMacs text and does your unsupported Mac need to be removed from the block?
[doublepost=1559752012][/doublepost]

Absolutely, Apple did this with Mac Pro 1,1/2,1 and Mountain Lion DP, IIRC.

UserPlugin Telemetry uses newer instructions that Core 2 Duo and Mac Pro 3,1 can't use. So far removing that works. There is something else in Catalina that I am having issues with on the MP3,1. I've got it to safe boot last night but lost Mouse. going to give it another go this evening.

Ahh, this reminds me of using LeopardAssist to install Leopard on my old souped up 1.4 Ghz PowerMac G4 AGP.
It's great to see the Mac hardware enthusiasts always find a way to extend the longevity of their machines.

What file has the unsupportedMacs text

InstallESD.dmg/OSInstall.mpkg/Distribution

and does your unsupported Mac need to be removed from the block?

If you install from a supported Mac to a MP5,1, you don't even need to mess with the distribution file.

InstallESD.dmg/OSInstall.mpkg/Distribution

Is this file / the installer not checksumed?

Not this one, it's a text file.

A lot of chatter considering it's only in it's first dev-only beta.

Thoughts on BCM94322MC (built-in wifi) support? What does copying the extension from Mojave get? API/ABI incompatibilities? Or simply signing that Apple would have to bless? Something else?

Still holding on to the hope 5,1 support will be in the final. I got the impression Mojave only got support because of holdouts (by opening up 3rd-party video cards, when the 2012 5,1 were otherwise ok..?) and that MDS bugs made them more headache than the holdouts. At the same time, with the above, 2010's might still be axed even allowing holdouts, from a purely momentum perspective. i.e. extend support for a planned single vintage generation one year longer. last year, 2012's were planned ok, but decided to include 2010's with effort. maybe this year 2012 is planned for the chopping block, but might get a last minute reprieve. that'd maybe lead to some easier community hackery to include 2010 and upgraded 4,1 if we're lucky.

on that point, do any 2012's have a BCM94322MC?

Thanks for all the hard work all

There is no driver for BCM94322MC on 10.15 DP1 and it's the standard AirPortExtreme for mid-2010/mid-2012.

Thanks, I will give it a go on my MP 3,1 tonight. I got it to save boot from a target disk in safe mode but want to try an install from itself.

Found this post #26, checked the file and then made the table, Macs that do not work with Catalina Sidecar:

iMac	MacBook	MacBook Air	MacBook Pro	Mac mini	Mac Pro
iMac13,1, iMac13,2, iMac13,3	MacBook8,1	MacBookAir5,1, MacBookAir5,2	MacBookPro9,1, MacBookPro9,2	Macmini6,1, Macmini6,2	MacPro5,1
iMac14,1, iMac14,2, iMac14,3, iMac14,4	.	MacBookAir6,1, MacBookAir6,2	MacBookPro10,1, MacBookPro10,2	Macmini7,1	MacPro6,1
iMac15,1	.	MacBookAir7,1, MacBookAir7,2	MacBookPro11,1, MacBookPro11,2, MacBookPro11,3, MacBookPro11,4, MacBookPro11,5	.	.
iMac16,1, iMac16,2	.	.	MacBookPro12,1	.	.

Seems the cutout is more related to Quicksync HEVC encoding from Skylake processors. If you check the table, 2016 MacBook that have Quicksync encoding support have Sidecar, while the 2015 model that is blocked have a Broadwell processor with just decoding support.

This is the interesting info:

Why MacPro5,1 is there on the blocked list if Catalina don't support it.

@tsialex : did the extact distribution Patch: Installer wrote all the files but the product was not bootable. Was not found in boot picker and not in startup disk control panel.

Install with a supported Mac for now, something on the installer is causing problems. AFAIK, no one found the exact problem yet.

tsiAlex, I would be very interested in a installer where you remove/edit the lines of code to include the 5,1. This would assume I had a supported metal card in my machine already and edited the boot args so I could just do a seamless install on my 5,1. I do not own or know anyone with a newer Mac to do the installation as you describe in your first post, but would love to try out Catalina.

Until the installer is patched, you only have two options:

1. Install Catalina with a supported Mac
2. Install Catalina manually (manually as you do everything, containers, partitions, folders, unpack files etc)

My goal is not Catalina initial DPs, but down the road.

He literally just said in the post above yours, that no one has figured out how to do that yet...

 

[Jegriva]

I imagine that at least 'some' ( more probably " a lot" ) of Apple's Catalina developers team own 4,1 & 5,1s and love them dearly.
I'm also supposing that they have already installed 10.15 on them.

The love is not in doubt, the security of Bloomfield chips is...

At quick glance, Thunderbolt 3 required.

Edit/ So I wonder if adding just a USB-C card would bring a MP5,1 up to spec? Probably not on PCIe2?

 

[tsialex]

No. Seems the cutout is more related to Quicksync HEVC (Skylake) and BT4.2 support, with both needed at the same time. It's not related to TB3, if you check the table, 2016 MacBook is supported and don't have TB3, but have BT4.2 while the 2015 model that is blocked have a Broadwell processor and only supports BT4.0.

 

[mazzeri]

No. Seems more related to Quicksync HEVC support and BT4.2. 2016 MacBook is supported and don't have TB3, but have BT4.2 while the practically identical 2015 model have only BT4.0.

Okay, thanks. So Sidecar is confirmed D.O.A. on the MP5,1. Bummer.

It's still early. I imagine he or someone else here will figure it out.

 

[tsialex]

If HEVC and BT support is really what are needed, you can upgrade your BT module for one with BT4.2 and activate RX-580 HEVC support (emulating iMac Pro with @h9826790 tutorial) down the road.

Probably with something similar as Continuity Activation today.

That's weird about the Sidecar support. I haven't seen anything on Apple's site that says only certain Macs support it. The preference pane won't open on my MBP 9,1.

Apple did not posted about it yet, not even on ADC, but it's clear what's blocked from the framework.

 

[tsialex]

There's a way to bypass the Sidecar block, some people reported working with some older MBPs with some artefacts and compression problems.

defaults write com.apple.sidecar.display allowAllDevices -bool YES

I have Catalina running on a Mac Pro 3,1.

Installed to a small hardware SSD RAID from my 2016 Mac Pro.

Removed Telemetry.

Rebooted with cmd x and x.

I did hack the installer disk to ignore CPU type and removed my model number from black list. Not sure if that helped any.

Came up with mouse and transparency. I have a flashed galaxy GTX 680 card 2GB brand new.

Did not install any patches yet.

No WiFi yet. Will look for my Broadcom one from mojave.

Screen is gorgeous on my 4k display.

Magic Trackpad is not working. Says connected. Ahbb it connects via the settings!

No need to mess with Distribution file, if you are using a supported Mac.

One thing that would be interesting, is to add boardID and model to the PlatformSupport.plist on Preboot volume and on /System/Library/CoreServices so you could clear NVRAM when needed.
