Hello, I have a MacBook Pro late 2012 with a built-in SSD (512GB). The SSD has two partitions, one for the OS itself and one for other data (profiles from two users). I want´to resize the first partition (+20GB) now with some free space from the second partition (-20GB). I don´t have bootcamp on the Mac. I boot from a usb-device created with "Paragon Hard Disk Manager for Mac". After booting I try to size the volumes but after applying changes I get the following error: Operation failed File system has allocation errors due to cross-linked files. Run OS built-in tools for checking and correcting this kind of errors Ok, so I start the Mac OS Disk Utility to "first aid" my disks. After finishing I try again to resize my partitions but I still get the cross-linked message. How can I solve the problem to be able to resize my partitions?
