I have installed a 870 EVO SSD in my mid-2012 MBP (running 10.15.7), and it's fast as greased lightning now!
LPX works perfectly (it doesn't stop recording/playing back anymore, and alerting me that there is too much info to be processed), and all browsers work perfectly except Google Chrome.
I deleted Chrome from Applications, restarted the computer, downloaded the newest version of Chrome, but every time I try to launch it, it tries to open for about 30 seconds (I can go to History and try to open my last windows tabs, but it won't open them), but all it does is beachball spinning, and then just quits.
Any ideas as to what's going on?
