I just upgrade from PD10 to PD11, I found an issue when copying files from Win7 guest to El Captian host. (1) copy from Win7 Explorer to /psf/x/folder not succeed, the copying not started sometimes, but if it started, the transfer rate is normal. (2) copy from Win7 filesystem to host filesystem using mv or cp command from host is extremely slow, some kilobytes per second. Is there anyone has the same problem? Or is there anything needs to be configured?
Did you try to reinstall Parallels tools? Also please try to repair disk permissions from the Disk Utility.
