Computer: 12" MacBook 1.3 GHz (512 GB SSD).OS: OSX 10.11.1Tick Tock:1825 Turned ok Macbook for first time.1830 Installed Pages, Numbers, Keynote, OSX El Capitan Update. Setup FileVault for Full Disk Encrpytion.1900 Went to meeting, used Notes.2000 Came back from meeting.2100 Installed Sublime Text 3, Homebrew (XCode Command Line Tools).2200 Installed dot files, but did not compleate (took forever, ironic).2300 Watched end of Mets game.0000 Battery at 30% plugged into wall charger to recharge.0006 Started Download of XCode 7.1 from App Store.0010 Download Complete0200 Started Writing this.0210 Still not installed.Now I understand that these CPUs are terminally limited, and that they will underclock under heavy sustained load. That effect seems to be compounded with charging the device while using it's CPU intensivly. But over 2 hours to extract and install XCode 7.1 is insane. Progress is being made on the install, the bar moves slowly, very slowly towards the right of the screen. But it's still pretty crazy that it's taking this long.

Updating to macOS Big Sur 11 beta from previous versions of macOS might take significantly longer than expected. Data loss could occur if the update is interrupted. (59101197) It did say that in the release notes, but I am pretty surpised how long it is taking to even move past the first 1%. It seems to be stuck on that level but there is no way to tell? Is there? Is there a console that we can log into so we can see the background progress of this update? Or a keyboard shortcut to show what files it's trying to copy / update / edit?
