I've had some odd issues that happened with some of our Macs in my company. We have over 100 Macs that are being managed with about 80 of those being used by employees. Other Macs are either shared or test machines.
Last Friday, we received a couple calls about someone's Mac freezing or locking up. The issue is that you can't type or access any menu bar items. You can open and close apps, but that's the extent. Throughout this week, we had a few more Macs with the same issue and have a total around 8 Macs with the issue.
I opened Activity Monitor, but don't see anything that isn't responding or using up resources. I was able to use Casper Remote and remote in as myself rather than prompting to remote into their side. When I remoted in, I wasn't seeing the issue that the user was currently having. I was able to type and open and close anything without trouble. Digging through the console and logs didn't show any issues. I tried removing the computer from being managed and then re-enrolling the Mac. The issue was still persistent. So far doing a hard restart fixes the issue temporarily.
The Macs are MacBook Airs and MacBook Pros, with a mixture of OS X Yosemite, El Capitan and a couple macOS Sierras. I can't find anything in logs or see any issues with profiles or policies that are going out. Has anyone seen anything like this?
Let me know if anymore information is needed.
