FreeRapid doesn't seem to work under macOS Sierra

I was used to work with FreeRapid under the earlier OS systems, but after installing Sierra? Problems?
Under the preferences now, no more possibility to check 'other sources'
For me FreeRapid seems to be out, because I keep receiving the message 'dammaged'

Could you try the "All platforms" version of FRD from the download page and see if it works?

I can also confirm that the Mac version doesn't work in Sierra, I get the error '“FreeRapid” is damaged and can’t be opened. You should move it to the Trash.'

The all platforms version doesn't work for me as of late either, it just launches and immediately closes. Though it did work in Sierra for a while, so probably something wrong with my Mac...

Na OS El Capitan se děje to samé co popisuje výše DowloadMan.
Můžete poradit?

I was able to fix the all platforms version by restarting, but the Mac version still doesn't work. I'm going to guess support for that one ended around Yosemite or El Capitan?
