Hello, try one of the following solutions:
(Usually method 4 works for most people)
1. If you unzip the file on a Windows machine and transfer the file to your Mac with a USB stick it might work.
I have also heard that it works if you download the zip using Chrome on MacOS and extract with Keka or Unarchive app.
2. MacOS is picky about which programs can be run (the first time) by double-clicking. To run a program that says "this can't be opened", right-click the icon and choose "Open". You'll be given an option to open the program, and from then on it won't bug you.
3. For Mac's having trouble installing FPV Freerider try going to the Mac's System Preferences>Security and Privacy> General Tab and check the box "Anywhere" to see if this allows your Mac to install FPV Freerider.
4. Open up terminal and type sudo chmode +x (fpvfreerider.app) and that should do it.
It should look something like:
chmod +x /Applications/FPVFreerider.app/Contents/MacOS/FPVFreerider
or
chmod +x /Applications/FPVFreerider_Recharged/Contents/MacOS/FPVFreerider_Recharged
(adding sudo at the start if needed).
Make sure you enter the correct folder path and app name (where the app is located on your computer).
After that you might need to go to your Mac menu System Preferences>Security & Privacy
If it says something like "Freerider was blocked from use because it is not from an identified developer" you need to select "Open Anyway".
