Sometimes after imaging, the computer name is wrong being “iMac-abunchofrandomcharacters” or just “iMac (#)”. This causes helpdesk to not be able to pull the IP address and makes remoting in difficult.
Open Terminal and run the following command lines (replacing * with the correct computer name from Helpdesk):
sudo scutil --set HostName *sudo scutil --set LocalHostName *sudo scutil --set ComputerName *dscacheutil -flushcache
sudo jamf -setComputerName -name * |
Restart the iMac and the name should be fixed. Check the device page on Helpdesk to make sure it’s pulling the IP address.
