Indeed Little Snitch v5.7.6 is running flawlessly here for me, but I did not install it, I upgraded from Sonoma with it already installed. Maybe there is a bug happening with the installer? Did you try to install v5 just to check?
No, I didn't. I clean installed mac OS 15 on a dedicated partition of my M1 MBP just for the sake of curiosity and I tried to install Little Snitch v6 right away: I believe there is a miscommunication problem between the LS installer and the new Security and Privacy pane because there is no prompt to authorise the new system extension
App Cleaner and Uninstaller DOES NOT work. Site says wait for update coming by Sep. They did the same with past MacOS updates.
Adguard is only partly working
-you can use it if set as automatic proxy
-Sequoia doesn't let you install network extension so it does not work with it
ps. it is probably due to a change in macOS and how it let you accept installing an extension from unidentified dev

Seems to be another case of "If the app was already installed and you upgraded to MacOS 15, it will work, but if you try to install on a fresh system, it will fail".
I can report that AppCleaner is working for me after updating to Sequoia, but seems like, just with many other apps, trying to install on a fresh system is failing.
I tried: LittleSnitch 5.7.6 installs and runs fine in macOS 15, then you can update to 6.0.1 and it will run fine too...
I can confirm that Final Cut Pro works as well as the motion VFX plug-ins and film convert.
It seems that the things that don’t work well are related to VPN and networking which never surprises me

I think we have a problem with the list in post #1. This is showing as working a number of apps (e.g. Little Snitch) which use System or Network Extensions. For these (from comments in this thread), it seems likely that there are two cases:
1) If macOS 14.5 is upgraded to macOS 15, the apps may continue to work. But,
2) Installs of the apps may fail on macOS 15, because of changes in how the extensions are permitted.
So, it would be good if those who have entered such apps as working would make it clear that "working" includes installation on a clean macOS 15 and not just continuing to work from pre-upgrade install. I am thinking of apps like:
Little Snitch (and other firewall apps),
AdGuard for Mac,
Any anti-virus with real time protection,
VPNs.
Possibly, virtual machine apps have the same issue with installation.

I'm seeing the same thing but for all having this problem, I find that I can share my ENTIRE desktop - just not various apps or windows.
Lightroom Classic is working for me, not tried PS or Lightroom, but I guess it should be a go.
I actually managed to install v5.7.6 (after a couple of attempts admittedly) an then update to 6.0.1
Adguard on a fresh macOS install is only partly working. You can use it as a automatic proxy but it will not work as network extension bc when trying to install extension there is no response from macOS (no way to click allow)
/just to clarify things, I assume it should work when upgraded and the extension is already installed.
