OSX 10.11.5 update - Don’t install
Just a warning.
I had an OSX update available in the app store this morning, which i applied to my 11" MacBook Air.
It downloaded & re-started the machine. But my lappy has now been “stuck” for nearly an hour saying;
“Installing Software Update: About 13 minutes”.
A quick look at the apple forums, & there’s a few people having similar problems.
…I’d leave this one for a few days, if i were you!
EDIT!
All ok now. I went out to lunch & the installation was complete when i got back.
…so if this happens to you, just leave it for a while.
