CapCut export time

Hi guys, my CapCut exports take soo long. It's around 3-4 hours for a 15 min video, even on 720p quality honestly. I use a 2015 MacBook Air (I know it's pretty old lol), but is there any way I could fix that and reduce the export time somehow? I'd also appreciate suggestions for laptops that'd be more suitable for video editing (both on the economical and pricey sides).
