Uninstall Security Software from your Mac. What is happening is most likely Firewall Settings are getting in the way. So, permit this connection, and then uninstall the Security Uoftware. You'll likely find the uninstaller on the Developer's website, somewhere.
B. Start with a Restart:
Restart your Mac, and see if it then is fixed.
C. Refresh Finder:
- Go To: Apple menu
- Select: Force Quit...
- Select: Finder
- Click: Refresh button
D. Unmount, then Mount the Drive:
Boot into Recovery Mode. (Silicon Chip or Intel Clip): Then, using Disk Utility, see if the Hard Drive is seen. If it is, then see if you need to click the “Mount’ button for it. Try rebooting once more. If of no success, then click unmount button, and then the mount button. Try rebooting once more.
