iMac late 2009 will only start in 'safe' mode, why is this?
Hi there,
I'm new to the Mac platform. I've been using one for 1-2 months and now I have a problem with my iMac 27" late 2009, Procesor 28 GHz Core i7.
For few days I made an Update for OS and after that it start /boot not in normal mode. I can use it only in Safe Mode with key "Shift" at start up.
What happened and how to fix it?
Es esta una buena pregunta?

How much RAM is in your system and what is the OS you are trying to run Sierra or High Sierra?

I installed High Sierra on this identical machine last week but did a clean install with no issues. Did your installation complete or did it hang? How much free hard drive space do you have now?

I have 8GB RAM and 1TB disk space. First I installed Sierrea after that I try to install High Sierra but no success. And one more thing my screen show some blue lines or blue small squares.

I've been fighting this problem since March.. It started after the upgrade to Sierra. (Not clean install) Blog after Blog blames the 4850 graphics card.. I did find one interesting thing.. the Sierra upgrade does change the Graphics Driver to another model i think at2000. It Does hang around 55% in normal mode.. Apple "Genius" bar did a cursery diagnosis and found nothing wrong.(thy dont touch anything that old). A Mac authorized repair center couldnt figure it out.. for $75.00 . Im like most.. that my IMAC is like a pet ..and i dont like the thought of putting it down. but after banging my head against the wall..its time to give up the ghost.. I soon realize that it wont be long before the updated opperating systems wont be backward compatible.. I hate to use the title to a Frozen song... But..."Let It Go"
