I'm rocking a 13" 2018 MBP w/ Touch Bar. Got it in November. But lately something is up... it's just so slow. First, wifi. Takes 10 seconds to load a page. My other devices in the home are fine, iPad, iPhone. Internet speeds are okay, not great but okay. But then opening applications too, just slower than normal I fee like. It could just be in my head but I don't even want to use my computer nowadays cuz it's slow. And I'm not editing video or photo, or running super intensive programs, editing a podcast episode now and then in GarageBand. How can I find out what is causing this? Thanks in advance. Also I have a Satechi dongle plugged in with an external monitor acting as an extended display. I heard from somewhere, that maybe a dongle plugged in on the wrong side might interfere with wifi. Idk
