How do I remote into my mac, or get someone to access my machine and help me out.
This question has been around for a number of years. There are lots of remote programs out there here are the top few I find work very nice with your mac.
Top one I would always use if you don’t have access to the network you need to connect to (i.e VPN) would be Teamviewer. Free to the end user, paid service for commercial user.
