2015 MacBook Pro - random slowdown

2015 MacBook Pro - random slowdown

Hello! i upgraded my 2015 Macbook Pro to Sequoia last december and it’s been working perfectly fine until recently.

Last week, my Mac apparently died with only 54% battery and after I had plugged it in, it’s been extremely laggy. Trying to minimalise or maximise a finder window takes at least 15 seconds with it lagging HORRENDOUSLY. It’s become pretty much unusable.

I have it dualbooted with windows 10 via BootCamp assistant and it works flawlessly on there, no lag whatsoever.

Initially, I thought it had been infected with a virus, but after doing a full system scan with Malwarebytes, it came back empty.

Does anyone know what might be the cause of this? it’s driving me absolutely insane 🫠

Specs: Intel Core i7 3.1GHz 8GB RAM Intel Iris 6100 Graphics
