MacBook is slow after upgrading to SSD
My Macbook is much slower after upgrading to an SSD and performing a clean install.
Troubleshooting tips I have conducted:
- Swapped back the original hard drive which confirmed that the cable is alright
- Updated firmware to the latest available version
- From recovery mode set the SSD as default startup disk
- Reset NVRAM
To compound matters, the SSD seems to perform as expected when connected externally using USB.
I am well and truly stumped at this point.
Edit: For the sake of clarification, when I swap in the stock HDD it’s faster than the SSD. When I plug the SSD to a USB port and boot, the difference in performance is significantly noticeable.
Is this a good question?
