Lul wot? No. You should prepare your mac to get futurerestore to work. Download ios 10.2 ipsw and buildmanifest.plist file sep firmware file and baseband firmware file from ios 10.3.3 firmware file.
Instead of downloading the whole 10.3.3 firmware you can use http://wobzip.org/ to unzip the ipsw file and only download individual files that you need. This'll save time and bandwidth
Go to this website website http://wobzip.org/ . Paste iOS 10.3.2 firmware's direct download link and hit Uncompress. It takes a while or so to do it. After that download only the sep firmware, baseband firmware& build manifest file for your device.
This way you don't have to download the whole 2.5gb firmware file.
Download 10.2 ipsw file from https://ipsw.me
Get your 10.2 shsh2 blobs of your device if you have saved it anywhere. Now Copy all of them into a single folder.

Extract futerestore. Open terminal and navigate to futurerestore folder(cd command). Give futurerestoremacos file execute permission(chmod +x)
Then type these commands in terminal while still being in the futurerestore folder.
./futurerestore –t blobs.shsh2 –b baseband.bbfw –p BuildManifest.plist –s SEP.imp4 –m BuildManifest.plist –w -d target.ipsw
