Hello, My early 2015 13" MBA has suddenly starting freezing randomly. It was occurring when on facebook in Firefox. So I uninstalled firefox and noticed it was also occurring in safari. Then it started happening when trying to open apps. So I updated to High Sierra and still had the problem. I did first aid in disk utility and then ran diagnostics. No issues were reported. The freezes were still occurring so I went to the Apple store. The genius ran his tests and said all hardware looked good on his report. He suggested a full clean reinstall which they did. Got home and still having the freezes which seem to be more frequent. The MBA is out of warranty and no applecare. Could it be the SSD going bad? Any ideas? Appreciate any help/advice. Thank you!
