I think my Mac was hacked, and I'm really worried about it. A freelance cybersecurity expert helped me regain access to my iCloud account and factory reset my computer. However, I feel uneasy because I lost all my activity and console logs that could have shown what happened. He advised me not to worry too much, but I'm not convinced. I believe this was a targeted attack by someone I know. Is there any way to recover the lost data? I reset my computer about ten days ago and haven't made any changes since then.

I know this situation feels overwhelming, but try to focus on securing your system moving forward! If you feel uncertain about your device's safety, consulting a different cybersecurity professional for a second opinion might also help put your mind at ease.
If you’ve factory reset your Mac and don’t have a backup, unfortunately, your data is likely unrecoverable. Once the reset is done, the information typically can’t be retrieved. It’s always a good idea to regularly back up important files to avoid losing them in the future!
It sounds like your computer might have been infected with a remote access Trojan (RAT). I suggest asking your cybersecurity guy about security apps that can help protect you from future attacks. Keeping your system secure is really important!
