I accidentally hit trust this computer on someone's macbook
I was just trying to charge my phone from someone's Mac and just hit 'trust this computer' without thinking. I am scared that it would've synced immediately so they have access to my photos, notes, etc. I didn't open the MacBook just trying to charge my phone nothing else. Does it sync right away as soon as I hit trust this computer so they have access to all my data? If so, how do I delete or untrust it?
