help! Ever since updating to El Capitan, when I first launch, if I right mouse click on a folder I get a spinning wheel (ugh) for up to 30-45 secs. Some times I get it when I launch an app, but no particular one. The frustrating part is this doesn't happen every single time, but 90% of the time. Also, it can appear periodically after running for a while, but usually it is related to the right mouse click. I read some of the postings and suggestions about putting DVD in but that didn't fix it. This never ever happened before El Capitan and I am at a loss of what else to check. I did look through activity monitor to see what was running and didn't see anything I thought could be the cause. Also, there are no login at launch apps set up so its not that either. I also noticed after the update before last to El Capitan a severe lag in file transfer to my NAS device. Before I would copy a large file in minutes, where now it can take up to an hour. I have plenty of bandwith, speed and again this only surfaced with El Capitan after the second update. Any suggestions??? Oh yeah and of note, prior to El Capitan, I never experienced any spinning wheels at all! I have a MacBook Pro (mid 2012) 13" 2.9ghz I7 16gb RAM with 240gb SSD and 75/75 FIOS internet.
