I've been a Windows user for many years until 2 years ago when I decided switching to a Mac. So my roommate had this Macbook Pro 2012, beautiful machine, was running Mavericks and we were both working in our living room as freelancers. I was constantly checking out his display, seeing how smooth he was operating everything. So after one year I go in and purchase a Retina 13 2014, it was running Mavericks, I update it to Yosemite and first thing I notice is lag, framerate drops, nothing compared to Mavericks. Years go by and now I was running Sierra and felt like my Macbook needed a fresh install, so I go ahead, install a fresh Sierra and there I am, happy that things are like brand new again. Well, I'm one month in and to be honest this thing feels sluggish. Not sure about smoothness, but it literally takes about one second or half a second to open almost everything. I don't know, I just installed Windows on Bootcamp a few weeks ago and I realised I forgot how it is to move fast between folder/files and opening/closing things. Checked activity monitor, all looks good, no malware, no viruses, nothing. In fact at first glance the OS seems like its doing fine, but once you start going through Finder especially, everything is slow. Am I the only one noticing this? I'm seriously considering ditching Apple because I'm also not a fan of my iPhone after I switched from Android. For the price you pay on these products, I might as well get something cheaper and expect such problems.
