Install on Mac
Download the disk image, drag Raptor Downloader into Applications, and open it the first time with right-click > Open.
Which download?
Apple menu > About This Mac. If Chip says Apple M1 (or M2, M3, M4…), use the Apple silicon version. If it says Intel, use the Intel version.
Open the download
Double-click the .dmg file. A window opens with Raptor Downloader and the Applications folder.
Drag it into Applications
Drag Raptor Downloader onto Applications. Then eject the disk image.
Open it the first time
In Applications, right-click (or Control-click) Raptor Downloader and choose Open, then Open again. If your Mac still refuses: System Settings > Privacy & Security, scroll down and click Open Anyway. This is needed once, because the app is not yet notarised by Apple.
Remove it
Drag Raptor Downloader from Applications to the Bin. Its settings are in
~/Library/Application Support/Raptor Downloader if you want to remove those too.
