i have the latest versions of Garageband on both my Macbook pro and my brand new iPad pro. My aim was to create rhythm tracks on the ipad and transfer them aross to the Macbook as the Macbook Garageband app doesn't have the facility to manually play digital drums (Why? Apple why? If you can do it on the ipad, surely it’s also possible on the Macbook) but no matter what i try, how many forums’ advice I follow, Garageband does not share. I have transferred macbook files to the iPad only to get an error message explaining that the files won’t open because the Mac version and ios version of Garage band aren’t compatible. Transferring the other way, from the ipad to MacBook,i get an error message on the Macbook saying the files can’t be opened on the Macbook because the ipad is using “a newer version’ of Garageband and they aren’t compatible. I repeat, I have downloaded the latest versions of both, and the Apple site tells me there is no later version for either device. Simply stated, I bought a new ipad pro to enhance my recording only to find it is useless for the task because Apple’s claims for Garageband - namely that you can share files between two Apple devices both running Garageband - are simply false. Doesn’t anybody in Apple check that the software actually does what they promise before unleashing it on the poor trusting public.
