I’ve finally upgraded to Mac OS X 10.11 at home. There’s really not much to say so far. The only new/changed feature I really see and use is Mission Control. Ohter than that it’s pretty much business as usual.
The process went quite smoothly. I started the download and left it unattended. Then I returned later and started the install and left it running unattended. Note that I usually never leave an upgrade running but they did take a few minutes and I had other things to do including even being out of the house for a while.
When I came back and the new login screen was presented I logged in with no trouble and only had to enter the Apple id for iCloud.
There may be features I’m using that are new or changed and I haven’t used them enough in the past so I’m unaware of the differences.
I hear that Notes has become quite good but I’m sticking with Evernote and Drafts on my phone.
