Trouble working off network.

Your report turned up pretty much what I expected. I am reasonably confident the issue below is the cause of your problem!

I see some issues in your report. First is you have Trend Micro installed which is considered malware by most experienced users on these forums. Mac OS is catlike in that it cleans itself, Mac OS does not benefit from nor does it require any of the following types of apps:

·      Antivirus Apps

·      Cleaning Apps

·      Security Apps

·      VPN Apps

·      Maintenance Apps

What these types of apps do is the exact opposite of what users want. They make Mac OS slow, appear buggy, can damage Mac OS and sometimes create unwanted behaviors. In short, they are really bad news!

So the first order of business for your computer is that you need to locate the developers. uninstall instructions for Trend Micro and please uninstall it. Because Trend Micro is pretty nasty stuff it tends to leave parts behind after being uninstalled, a testimony to how poorly written the app is! To fully ensure you have uninstalled it please download the free version of FindAnyFile directly from the developer. Then have it search your system for the following:

·      Trend Micro

Have it Trash any files with those names in them and then ensure the Trash is empty.
