Forgive me - but this thread has drifted from the original issue! i.e. that MANY people have had problems - some severe - with the update from 10.11 to 10.11.1
I repeat what was asked earlier - if it worked OK on 10.11 - why problems with the latest .1 update (which was supposed to improve stability? It took me four attempts to get the update to work from Yosemite to El Capitan - then I gave up after the further problems with the latest .1 release.
So, to sarcastic 'experts' with bragging points - please, do NOT try an put other people down here. Do NOT use this forum to brag. TRY to connote the good work - and just give SOLUTIONS.
You have said earlier that the problems are usually caused by 3rd party software which is not (yet?) compatible with El Capitan. I recall on earlier OS update that had a list of software that did NOT work with that update. Also, was there not a facility from Apple at that time to move such software to a separate file?)
I have given up on this update - for now. Fortunately I had backups on Time Machine and Super Duper
IF - I try again when my frustration has calmed down - I look forward to POSITIVE suggestions - which can realistically be 'filed'
Enough childish behaviour! Give us clear solutions - to MANY (statistically significant) problems! With apologies to statisticians!
