Hi all, rMB m5/512, Sierra 10.12.4. I'm using Chrome as my primary browser and all is good and well. Until I shut the lid and let the Macbook fall asleep a few times. And then it just gets slower and slower. Has anybody else encountered this? Quitting Chrome doesn't help. Quitting ALL apps doesn't help. Only restart does anything. I blame Sierra, because I don't really think it's gone past beta stage yet, but I'm not sure, hence me posting this here. I'd go back to El Cap but then I'd lose my backups, also I don't know if it's possible to install El Capitan and then restore all data and documents from a Sierra backup... Thanks for all/any replies!
