    All research, testing, and releases of tools and patches relating to macOS 10.15 Catalina on Unsupported Macs should be posted here.

    Machine Support
    As it currently seems, all machines with at least SSE4.1 support (C2D penryn and upwards) seem to be able to at least boot Catalina. This covers all of the machines that were able to run Mojave, even the officially unsupported systems.

    Some systems appear to be fully compatible. However Apple blocks them from installing Catalina, due to existing configurations of those systems, which are not compatible.
    Those systems include the Mac Pro 4,1 & 5,1 as well as 2010 & 2011 iMacs, if they feature upgraded, metal-compatible GPUs and compatible WiFi/Bluetooth-cards. Mac Pros also require to be running non dual x55xx CPUs (like X56xx) to omit audio stuttering. An installer to enable these systems is available here.

    Early-2008 or newer Mac Pro, iMac, or MacBook Pro
    MacPro3,1
    MacPro4,1
    iMac8,1
    iMac9,1
    iMac10,x
    iMac11,x (systems with AMD Radeon HD 5xxx and 6xxx series GPUs will be almost unusable due to the lack of acceleration)
    iMac12,x (systems with AMD Radeon HD 5xxx and 6xxx series GPUs will be almost unusable due to the lack of acceleration)
    MacBookPro4,1
    MacBookPro5,x
    MacBookPro6,x
    MacBookPro7,1
    MacBookPro8,x

    Late-2008 or newer MacBook Air or Aluminum Unibody MacBook
    MacBookAir2,1
    MacBookAir3,x
    MacBookAir4,x
    MacBook5,1

    Early-2009 or newer Mac Mini or white MacBook
    Macmini3,1
    Macmini4,1
    Macmini5,x
    MacBook5,2
    MacBook6,1
    MacBook7,1

    Early-2008 or newer Xserve
    Xserve2,1
    Xserve3,1


    Video Card Support

    As with the machine support, all video cards that were supported on Mojave, supported or unsupported systems, can still run Catalina.

    Pre-Metal AMD video cards (Radeon HD 6xxx series and older without acceleration, Radeon HD 4xxx series and older with acceleration.)
    Pre-Metal Nvidia video cards (GeForce 5xx series and older, i.e. 8600M(GT)/8800M(GT), 9400M/9600M(GT), 320M/330M)
    Pre-Metal Intel video cards (Intel HD Graphics 3000 and Intel HD Graphics Arrandale)

    Full acceleration for older Nvidia and Intel cards has been achieved on macOS Catalina beta 1 and on macOS Catalina beta 2.


    Installation

    macOS Catalina can be installed on an unsupported system using @dosdude1's macOS Catalina Partial Patcher tool or @julianfairfax's macOS Patcher 3.0 beta tool.


    Catalina Builds and Installer Versions

    2019/06/04 10.15.0 beta 1, build 19A471t, installer 15.0.11
    2019/06/17 10.15.0 beta 2, build 19A487l, installer 15.0.15


    Credits

    I guess not this time. My goal is to get it running as soon as I can and I could certainly use the help of people more or even less experienced than me. And thanks to @dosdude1 and @Larsvonhier, I now have my own MacBook4,1 to use for testing unsupported macOS on. As I'm currently the only developer who is developing a patcher tool that supports the MacBook4,1, this is very useful for me. Thanks a lot to both of them.

    I hope we'll be able to overcome any issues that arise. Personally, I won't be of much use today (Cupertino time) since I live in a different time zone. School is also going to get in the way. But I'll still have time to work on what will most likely be an amazing ongoing project.

    I had intended to make this thread once the OS name was officially announced. Now that it's been done earlier than I intended, please change the title accordingly.

    Was just going to say that. I'm changing the name. We're going to run Catalina on our older devices then.

    Sorry if I went a bit too fast. I changed the name a minute ago.

    Please make this thread a Wiki thread like the Mojave one. Thanks.

    I'll do that now. There's a category for it now.

    Edit: I still don't seem to have the option for that.

    Are the system requirements the same as Mojave? Hopefully it can be patched to run on the 2010 / 2011 Macs. My 2011 17" MacBook Pro can assist with the beta testing.

    No info yet. I'm refreshing the Newsroom right now.

    I hope I can run it on my late 2008 uni MB.

    And you hit this early!

    Ugh, just like last year, Apple didn't announce system compatibility. I'll have to wait until I'm able to download a copy in the Developer Portal to find out.

    They did actually, it was flashed on a quick slide during last year's keynote. Very strange, I would've at least expected them to mention the requirements for iOS 13 this year.

    Those are in the Newsroom post for iOS 13. "New software features will be available this fall as a free software update for iPhone 6s and later, and will be available with iPadOS for iPad Air 2 and later, all iPad Pro models, iPad 5th generation and later, and iPad mini 4 and later."

    I think it's iPad Air 2, Mini 4, and all Pros, iPhone 6S and SE or newer, and iPod touch 7.

    Hopefully no devices are dropped with OS 10.15 because almost nothing in the downlevel has changed.

    Exactly as I expected for iOS 13. Good to know my iPad Air 2 is safe.

    I'll try it on my laptop with non-Metal NVDA GFX once Dev Beta Installer is ready.

    I wasn't expecting any change in the requirements for MacOS. Let's hope I'm right about that as well.

    Oh dear. We might have a big problem here. "macOS Catalina runs in its own read-only volume, so it’s separate from all other data on your Mac, and nothing can accidentally overwrite your system files." https://www.apple.com/macos/catalina-preview/
