Can’t find my previous thread on this - if there was one, or many.
In around 2013 I set up my dad with a 2008 iMac, whilst at the same time getting a 2009 iMac for myself. Both were running Mavericks, and I made great use of the “Back to my Mac” feature of being able to remotely access dad’s iMac when he (frequently) needed help. The app doing the actual connection was called “Screen Sharing”, and is still a standard Mac app from Apple - however they hide it away, instead of simply having it reside in the Apps folder for people to make full use of.
Whenever dad needed help, he just had to confirm his current IP address (as he is on a dynamic address that changes regularly), and then I would be able to remotely access his computer from 400km away, and see what the hell he was talking about! Then I could also take control of his computer if needed to quickly fix his problem/s.
Then in around 2018 it stopped working. Bugger!!! Back to the dark ages of cryptic confusing phone calls without any visual to decipher what my father was trying to describe. Numerous visits and changing settings etc etc did nothing to get it to work again, and most of the “other” options for screen sharing tended to require lots of $$$.
I’ve just set up my dad’s new M1 iMac sigh of relief One of the biggest factors when setting it up - for me - was to get the screen sharing working again. Unfortunately - I still could not get it to work. I believe that Apple has “plugged” the option to remote in using your IP address. But, someone here (@jaysee ?) or on Mac Rumors suggested using the Messages app to share screens. It didn’t work on Mavericks… but… from the Big Sur (M1 iMac), to Catalina (my MacBookAir) -
And, it’s easier than before! I can just open Messages on my computer, go to a message I’ve sent to dad, then go to the “Buddies” menu, and “Request to share screen”. A message pops up on his computer asking if he wants to let me in - he says yes - and I’ve got access. Either to view, or control.
I just did a test run from 1km away (motel room; making absolute sure I wasn’t still on his WiFi when I made the connection from his house), and it works fine.
I did notice - it still uses the same Screen Sharing app…! But this looks like it should be easier than having to get his IP address each time.
Glad to have this feature working again. Hope anyone else who needs it can use it for their own tech support assistance.
