Boot Camp: Windows support software could not be saved
I have recently attempted to use Boot Camp to partition my 2015 Macbook Pro and install Windows 10. However, I keep coming across this error whereby the "Windows support software could not be saved to the selected drive" due to having "not enough space on the disk" I have searched for solutions and attempted some of them including turning off automatic backup on Time Machine and disabling "Optimise Mac Storage" on iCloud Drive.
I have set aside 80GB for the Windows partition (more than the required 60GB). I hope someone might be able to help me with this problem.
MacBook Pro 13", macOS 10.14
