IMAC external monitor not working after new OSX EL CAPITAN

Hello guys, after I installed new OSX El Capitan, my external monitor gone blackout completely (Samsung 22 inches monitor + APPLE Mini Display to VGA cable, working fine all the while), I am not sure wheter this is "another trick of making money created by APPLE HQ in US" or is only my IMAC got infected by some kind of virus

Please help me, thanks

hi all. after i installed latest update for OSX el capitan. if im not mistaken security, my MBP failed to log in.

while loading after i insert my pasword, it will shutdown automatically.

but when i log in to guest user account, there is no problem at all accept it can only access safari.


when i open recovery mode and check my disk, its healthy and dont have any problem

So far mine ok. All apps and functions like normal.

I experience some apps having this issue, but after I download their latest update, it is fine.

So if you use some apps that does not having anymore update, it is time to look for alternative.

Ok this might sound silly. But can anyone help me make a Bootable USB OS X El Capitan installer on a 8GB stick and poslaju it to me?
I just replaced ssd hdisk. No other MBP or iMac lying around. Plus I'm nowhere near any Apple Authorized Service Provider cause of work. So I can't make my own bootable stick.
Will pay for it.
Anyone interested PM me.

Few of my machines have same problem after clean install El Capitan.
I did try chrome, no problem.

i can't download el capitan at all..error when i click download..anyone know how to solve it?

10.11.5 available now

frankly NOT MUCH DIFFERENCE at all.

Haha cause the new OS will be announced later this month

How is it ?

Wait for september la. Hehe

To be honest i don't see any difference

Same here. No problems encountered.

A second macOS Sierra beta is available for public beta testers today

Anyone on Mac OS Sierra beta? To be honest, after my experiences with Snow Leopard beta onwards to El Capitan beta, I wouldn't dare to go into the beta phase again with my Mac Pro, because it just stops working due to the OS not being identified by my essential applications. I'll just wait for the official release this time around, and will get my popcorns ready. Just too much hassle for a day to day use through my past experiences though. Do let me know how does the beta perform especially on the Mac Pro, and also how does Siri perform in a desktop environment?

Ill agree for us to wait.

If you do no have an extra Mac to use, its better to stick and wait for the official release.
Upgrading to a beta may make you lose all you stuff, so if you insist in upgrade , pls make sure you backup first

From the word "beta" itself, some hiccups and loopholes within the software are expected. I'm currently typing this post on a Retina MacBook Pro that is running on macOS X Sierra Beta 2. So far, it is more stable than the previous beta version. Perhaps stable enough to use as a daily driver.

That's mainly the reason why the standard user should not upgrade until the official version in my honest opinion. Unless those computer savvy types who are literate with coding and troubleshooting to help the developers should proceed. Best it to perform a Time Machine backup before anything. Losing years of work would definitely be a pain in the arse, for just being 'at the edge' for some people who wants to always be updated just because.
