Boot problems, slow and lagging MacBook
My macbook suddenly lagged, like it takes a full minute to open an app or a file, I tried to restore it to factory settings and reinstall Mojave (since I did not have a time machine backup) but it still had the same problem. Also when powering up,when clicking the power button the screen just flashes and shuts down, I need to hold down the power button for it to properly boot ( this happened before and after the restore) but when it does boot up it still is very slow and the colour wheel just spins for a while before opening anything . I did the first aid and diagnostics and it said there wasn’t any problems found. Is there any way to fix this on my own or would I need to bring it to an Apple store?
