Security update disconnected network devices
For the second time in recent months I have been frustrated with Apple updates. I updated to Yosemite and found that the network devices that were not of an Apple origin could no longer connect to my imac. I reverted back to Maverick and everything was fine. Mathis morning I agreed to update a recommended security update, gues what? My non Apple network devices cannot connect anymore! I wasn't too worried as I had been using TimeMachine to protect my data so I thought I would just roll back to yesterday. Nope, the NAS that had been happily accepting my Time Machine backups was no longer accessible to restore from! Mis there any other way to roll back this security update without me having to start all over again? The NAS I have been using is a WD Mycloud and if I connect it directly to the imac via a cable, the restore asks for a name and password to get into the WdMycloud time machine, I tried wd_backup, backup which used to work for my old MyWorldBook, but this didn't work either. Any advice gratefully accepted.m
