Why on earth you want to disable binary signature checking?
It's required by mySIMBL and colorfulSidebar which I'm using in Mojave and previous macOS versions.

I'm aware of the risk, have been using this since Mavericks w/o probs. ;) The author @w0lf is a member here.
The app itself is not the problem, the problem is disabling binary signature checking system wide. Anything will be executed.

I had to do the exact same thing not only for MySIMBL but something else I can't quite recall. This was... uh, many years ago, all still running strong. You just have to be careful about what you do.

I just upgraded to the DP3 with the dosdude's installer over DP2. I only attended it in the beginning when I pointed where to install it. After I came back to the computer it was already upgraded and the wifi was working. So I guess it automatically patched it based on the hardware.

Damn... anyone else notice Catalina uses a helluva lot of RAM?

In Mojave, my usage was around 9-10GB... in Catalina it's 15GB or more. Good thing I upgraded to 24GB recently!

Yes, but Catalina has every debug and logging option enabled by default, so memory and CPU usage will be greater. For now it's useless to compare Catalina with Mojave, revisit this after the GM when both will be comparable.

Some users are reporting higher Geekbench scores in Catalina... I, however, am not noticing this. Things have stayed the same between versions so far. Hopefully things will be different in the Beta vs GM... assuming in the next 3 months Apple still allows the -no_compat_check input and doesn't change anything.

Apple uses -no_compat_check boot arg for debug purpuoses since Yosemite, it will be probably easier to start compiling things for AVX support than removing it from the kernel.

It's weird that they even allow it. Something as simple as that bypasses their "impassable" walls...
They need it, that's why it exists.

Apple don't care with tinkering Mac owners trying to squeeze more years from old Macs or even hackintoshers. The day that this two categories start to bite the bottom line it will change, but for now…

I installed Catalina on a Mac Pro 5,1 disk using a supported mac, then used Catalina Loader. I have a Broadcom
BCM43xx and Nvidia GTX 680. Everything worked fine. The only obstacle is Apple! It seems their decision to exclude MBP 5,1 is arbitrary. Instead of blocking a mac that can be upgraded, like the MBP, they should check for hardware requirements as they did with Mojave and Metal capable GPUs, then allow or disallow the install.
I am hoping that they will reconsider the block and let us use these great machines.

Free ram is wasted ram...

I agree, but assume that high memory usage is not due to memory leak, or unnecessary system monitoring / log (for beta OS).

i am running Catalina Beta 3 on a MacPro 5.1 with a Metal GPU. I used dosdudes catalina patcher.
Everything seems to run fine except Mail.
During opening mail, i see my content. But as soon as i click on an e-mail, Mail crashes.
I use gmail account with imap. As soon as i disable the mail account in gmail everything works fine.
Any tips?
Thanks

This is an earlier beta OS, this kind of bug is quite normal indeed. You better report to Apple.

BCM94322MC, the original one from mid-2010/mid-2012 is the one that don't work with Catalina - this info is on the first post, re-read it.

BCM94360CD and BCM943602CD works.

I have a BCM943602CDP card which I installed last year in my 5,1 supporting BT4.2 and 802.11 a/b/g/n/ac. However I have no wifi recognised and BT Handoff and Instant Hotspot = No. I used the dosdude installation, have tried toggling WiFi fixes in the post install. Any ideas?

You should report/ask directly on the thread macOS 10.15 Catalina on Unsupported Macs. Using a supported Mac or VM to install, it's recognised perfectly, Wi-Fi at least since BT Handoff and Instant Hotspot more effort, so I suppose it's a collateral effect of the dosdude patching process.

Anyone having issues with this running on a Mac 3,1?
[doublepost=1562815776][/doublepost]Sorry, should have stated, getting this on a 3,1 Mac Pro. I can’t seem to get it pushed through.

MP3,1 needs a lot more effort than a MP5,1:
  • You need to patch the BootROM for APFS support. This is risky, be warned, but doable.
  • The Telemetry plugin,
    /System/Library/UserEventPlugins/com.apple.telemetry.plugin, don't work with any C2D based processor, your MP3,1 Xeon is a C2D Penryn based processor and can't be upgraded to one that the plugin works, so you need to remove it or your boot process will hang.
  • Only NVIDIA GPUs work with MP3,1, Netkas patch for AMD cards works for 10.14.5 at the moment.
  • Probably more tweaks are needed, like the install of BCM94321MC/94322MC drivers and etc.
You probably should ask on the macOS 10.15 Catalina on Unsupported Macs thread, there are more people with MP3,1 there.

I also asked in there. Thanks for the response. I understood all but the Xeon part of that. Are you saying I have to upgrade the chipset to get it to run? Or something else. Thanks

All MP3,1 supported Xeons are incompatible and you can't upgrade to a compatible one, so the
/System/Library/UserEventPlugins/com.apple.telemetry.plugin has to be removed or the boot will hang.
