iMac 5K problems.

Question

Hello.Im having several problems with my iMac 5K(late 2015), the pc will shutdown and restart just out of blu. Also when using iMovie it won&#x27;t upload videos( to YT) or share then inside the system. Other times iMovie just shutdown while attempting to share content, sometimes even the computer it self shuts down. I have the error monolog but I don&#x27;t know how to post them here. I tried format the computer and also I erase the hole system before reinstall the OS and still the problems continue. I have a total of 24 GB memory install, could these be the problem ? Do I have to upgrade the memory to a proper 32 GB ? Thank you for you&#x27;re help in advance.

Mac OS was designed from it&#x27;s very beginnings to be EXTREMELY secure and does not need any antivirus, cleaning or ANY other third party maintenance app. Locate the uninstall instructions for the Avast AV app and follow them. Then restart and retest.

MotorNippon · Answer

Hello thank you for the help. I have another diagnose but for some reason I can&#x27;t get to post here, was the anti-virus causing the problem ? I remember having a similar problem before I got the anti-virus .

rkaufmann87 · Answer

If you uninstalled the AV app then please follow the steps below:Please  post an EtreCheck report of your system and we can look for any obvious issues. Please click the link, download and run the app and then post the complete report it produces as your reply to this message.

MotorNippon · Answer

ok thank you for the help. I did uninstall AV I&#x27;ll send you other report as soon as I get one.
