macOS 10.15 Catalina on Unsupported Macs

[nekton1]

Could you elaborate? Was it the Catalina beta 5 notice or something else?
It looks like wishful thinking on your part—there is no beta 5 release that I can see on either developers' or seed sites.

Beta is out, I think. Just received a mail from Apple.

I installed Catalina to the same container that Mojave APFS is on, and I lost the option to boot Mojave now without running post installer again. Is the proper way to do this is create a seperate partition/container for each OS since I don't have native APFS support?

Yes you need to have a native APFS support in order to install a macOS on a volume under the existing container. Separate partition/container works great, you just need to decide what size you want as there is no space sharing between partitions.

Installed Catalina on a MacMini 3,1 everything works except WiFi and Mouse and keyboard on boot is a problem. Any ideas would be helpful.

When you say Everything works on a Mac mini 3,1
does that INCLUDE Maps and Photo's too, please?

Thank you

Sorry. I received a mail from apple, "Try the new iOS, iPadOS, macOS, and tvOS public betas" so I thought it was that.

I tried with seperate partition, both APFS. I still only have one EFI boot in my options.

I think I will just go back to HFS for Mojave

You need to apply APFS ROM patch if you want multiple APFS partitions.

oh ok, I have the nvidia chipset so I will hold off on this for now since I was reading it may brick

Curious could this be why I couldn’t make Boot Camp work?

Personally I had no issues with Bootcamp(Windows 7) when I only had an APFS patch. I was even able to upgrade High Sierra to Mojave(clean install) and still kept my Bootcamp partition intact. It has been awhile and I don't have a Bootcamp on my SSD anymore(I keep it on my original 160GB HDD with Snow Leopard).

I DON’T have the patch (I don’t think) and when I try to set up Bootcamp it hangs trying to create the partition.

actually no... brightness, auto-brightness, night shift... all these things works perfectly

I confirm native brightness control doesn´t work in Macbook Pro 17" late 2011

I can see the intel HD 3000 is not exactly the same.

APFS ROM patch and APFS patch are two different things.

APFS ROM patch and APFS patch are two different things.

I understand that, I was just wondering if not having the patch was why Boot Camp did’t work. I guess it unrelated.

Sorry. I received a mail from apple, "Try the new iOS, iPadOS, macOS, and tvOS public betas" so I thought it was that.

I also received a mail from them "as a member of... test-driving pre-release versions" where clearly specified in subject "macOS beta", who knows what they are cooking for this Catalina beta 5 , probably today they should release it, or they may slide on next August month early days.

i would start fresh and do a clean install of el captian...Then install os mojave on a unsupported mac..10.14.6 came out a week ago and format it in AFPS...Once you get that far..Partion your hardrive and do a clean install of 10.15 in AFPS format on the #2 partition..And if it still does work you can reboot into 10.14.6 until the final release of 10.15 in ready..hope that helped..that should work...

How would I go back to el captain if I am already on Mojave on my unsupported IMac 12,2 it is the only Mac? All other computers are Windows 10 PCs

Simply, install High Sierra. If you mean go back with your settings and users, it´not posible. Unless you have a backup.

I don't use Maps and photos on this machine, it is just a machine for home automation. But I did test it I could get directions but Map background was black no streets. Then it just crashed. Photos crash on load.

 

[joelw135]

I found that my MacMini 3,1 is constantly looking for updates to the OS and never says I am up to date. That is not good. OK I rebooted twice and update is working. This is very buggy. My MacBook Pro 7,1 so far Maps and Photos not working they crash.

Your choice of words is a bit confusing, as "not having the patch" implies that you either using HFS+ or your machine has native APFS support from Apple.

macOS Catalina Dev Beta 5 is out finally the Catalina Patcher downloaded macOS Mojave

Wait a second. Am I reading right or did you just say the patcher downloaded Mojave?

 

[jackluke]

Catalina beta build 19A526h , all the main system binaries have the apple compiled date of "Yesterday", I don't remember a so very close compiled date versus release date.

At least 3 days before for their internal testing, instead just one day.

 

[TimothyR734]

This is the correct version but look at the date created etc
