Recording audio from a vintage 3" reel to reel player

Thanks for your quick response. No, I'm not using the Apple Pro App to capture the recording? I don't have that software and that's my question: What software do I use? I just have the standard apps that came with the computer, Microsoft Office, iMovie and some drawing apps. I don't think I need anything fancy as this will most likely be a 1 shot deal to digitize about seven 3" reels. I just want to digitize them and be able to adjust the speed (slow it down) somewhere in the process. I have no experience yet in running iMovie; however, I searched iMovie's help file and it seems there is a way to adjust the audio speed but don't know if that will work for what I want to do.

Thanks, I think I'll try Anytune. It looks like the simplest. Now how do I get the 3" reel digitized? Do I use QuickTime Player? If so how do I get the bluetooth signal from my bluetooth transmitter into QuickTime Player and then is the QuickTime Player file format compatible with the Anytune required input format? Sorry for all the questions. I've not done any of this before.
