nope you just need to move the .tax2024 file over and use that to transfer on Mac. Some folks have reported issues with doing the transfer after starting a new return on Mac it hangs at "Continue", if you get stuck instead do Open Tax Return in TT2025 and open the .tax2024 file directly and it will kick off the transfer into a new return.
if you're retiring an old PC remember to save the PDFs with all forms and worksheets for your records and do this every year when you file, don't rely on later accessing old .tax files or s/w as Turbotax does not support reinstallation/reactivation of software after 4 years (current year + 3 prior)
