"Path of Exile" is available for both PC and console, and Mac is also being released. The Mac version was originally released on PC in 2013 and moved to Xbox One and PS4 in 2017 and 2019, respectively, and released with the Heist extension.
The Path of Exile platform does not currently support cross-play or cross-save, and all the information about the saved file is related to the platform you log in, including between PS4, Xbox One and PC. Nothing will be lost! If you happen to use POE Currency at the same time, PC and Mac can cross-play and cross-save between the two.
According to chief designer Chris Wilson, this is a natural decision, because most of the avid "Path of Exile" players are staff and they may use PC and Mac at different times of the day (I know I would), play Path of Exile without restrictions.
So, for PC and Mac, you can transfer everything and save it to the cloud-basically just like playing on other PCs. Just make sure you log in to the same account and all your characters, weapons, skills and loot will be inherited. Since PCs and game consoles may bring unfair advantages in one or more ways, it is difficult to implement cross-competition, so it is worthwhile to stick to only one way at present.
Of course, in addition to these, if you want to quickly upgrade through your own skills in the path of exile, there are certain restrictions. You can use other methods, such as POE Exalted Orb, which can quickly upgrade in the shortest time, and players can more Enjoy the game calmly.
