Trying to sync my iPad Pro to my Mac Studio

Hello redhouseportugal,

My suggestion would be to update your iPad Pro to the latest version of iPadOS (this is probably why your Mac Studio is giving you the message, "Mac Studio not supported."):

Update your iPhone or iPad - Apple Support

• First, Back up your device using iCloud or your computer.
• Then, connect your device to its power source and connect to the internet with Wi-Fi.
• On your iPad go to "Settings" > "General," and select Software Update.
• If you there is more than one software update available for your iPad, select the ones you want to install. (You should probably select all of the software updates you see, but you can install them one-at-a-time if you want to.)
• Select "Install Now." In some cases you might see "Download and Install;" if so, select this and the update/s will begin to download onto your iPad. When prompted, enter your iPad's passcode and select "Install Now."
• The updates should begin installing. This will probably take several hours.
• Your iPad is now up-to-date!

Hello I'm also having this issue and I can't seem to connect. I seem to have followed all the correct procedure. any thoughts? I think all iPad Pros (I have the larger model) work is that correct?
