FYI - This also happens in Mojave and I tried both Homebrew and the app download on Github.
I tested this more for you and the version that works with Mojave and probably Catalina is version 1.9.2
Related recent brew changes:
https://github.com/Homebrew/homebrew-cask/pull/95155 (Updates to 1.10.0)
https://github.com/Homebrew/homebrew-cask/pull/95232 (Prevents installation on macOS < BigSur)
Awesome thanks for the speedy response.
also, previous releases were properly signed by 'Developer ID Application: Code and That Ltd (B3T8QSC4HG)' while the newest release only has an adhoc signature. what is going on here?
My install of bitbar was updated by homebrew to 1.10.0 which gives me the same error message as OP got when they tried to run it.
I uninstalled the new version:
brew uninstall bitbar
But trying to install the old version through homebrew is not readily possible as far as I can tell.
There are a bunch of idea on how to install older versions of stuff through homebrew at https://stackoverflow.com/questions/3987683/homebrew-install-specific-version-of-formula but those methods are both convoluted and many of those ways don't seem to work any longer anyways.
Is support for older versions of macOS coming back in a future version of bitbar?
I am running macOS Catalina.
I believe it is a good time to take a look at the promising successor SwiftBar
I somehow rolledback to v1.9.2 patching the formula.
I'm not sure but I'll share it if that's hopefully useful for anyone else here for the time being.
You can find the path to the formula by brew formula bitbar and apply this patch.
Alternatively, you can directly edit the formula by brew edit bitbar.

@matryer was the breaking change intentional?
@piotrd No I think this is a build target error... let me build with a lower build target and see if that works.
Try v1.10.1 - although it seems like the vertical alignment issue persists :(
@matryer: Just want to say thanks for the fix and this awesome project. <3 bitbar
On Catalina 1.10.1 runs now, but nothing in the menu is clickable, for example the howbrew script plugin "Upgrade All" does nothing. In 1.9.2 it would launch a terminal and run $ brew upgrade
Hmm, weird. I will have a look at this tomorrow @AddictArts and see if I can figure out what's going on.
For the record: v1.10.1 also complains that it cannot be opened because Apple cannot check it for malicious software.

thats what i mentioned above:

This one was built with the correct code signing. But I think there are still issues on some operating systems. Could somebody give that a run and see if you still get that rude "this could be malicious" message :)

Thanks for trying it—will investigate.
