MacWiesel Posted September 24, 2019 Share Posted September 24, 2019 I did a fresh install of MacOS 10.14.6 because I had a lot of trouble after upgrading from 10.13 (random boot errors, preview problems and what not). The problem now is: My disk speed is terrible. I just compared to a brand new Macbook Pro 2018 and the result (see attached pics): Macbook Pro: 2667/2570 MB/s Hackintosh : 303/1673 MB/s After a bit of research I tried enabling TRIM again. No difference. Any idea how to fix this?

If the M.2 slot is set for 4 x lanes as it can be expected, you should be getting the same sort of performance I reported in the post linked above. Sorry für the late answer. In my bios is no setting regarding the m.2 slot and the speed is still terrible. Any more ideas?
