My wife has a MacBook Pro (13-inch, 2017) with 256GB SSD. She recently purchased a iPad Air 4 256 GB.
She (unsurprisingly) can't backup her iPad to the MacBook as it requires 60GB.
Is it possible to backup to a USB HDD?
If so how?
I finally got around to trying (realistically I was allowed to access my wife's laptop) the suggestion below. Unfortunately I can't seem to access the MobileSync directory.
I had previously checked on my iMac but I have disabled SIP.
sudo won't let me access the directory and results in "operation not permitted" although most of the other directories are accessible.
Any other suggestions?
