Do Macs in a corporate setting behave more erratically?
No - Macs in enterprise are generally less erratic, more agile, less expensive, more productive and let people get work done with less unpleasantness like cryptic error messages, slow deployments, hard to diagnose issues, and things that require a large, IT support orgainzation.

In 2015 - IBM was 6 months in to a user choice program allowing their employees to choose a Mac or a PC and they had realized faster deployment, less support and cost savings of somewhere south of $300 per device.

In 2016 - IBM is now betwwo 90k and 100k Macs deployed and is realizing savings of $250 to $500 per device type in cost to buy, support, provision Mac hardware versus PC hardware.

The videos from above should be posted within a month. Also keep in mind that this is a customer / partnership success story, but the hard numbers and experiences of people I spoke with make me feel these numbers are both fair and real as well as transferrable to many other enterprise organizations immediately with low risk if the company decides to support their employees and let them choose their platform to get work done.

If you are getting slow performance, it's likely due to something that can be fixed without a lot of delay if someone looks into the root cause and decides to support your location.

If you have stability issues - consider getting a good backup and wiping. Just add back the apps you need. My feelings are that the only changes that organizations make tend to increase stability of the Mac OS except for one.


antivirus software other than Apple's GateKeeper and Xprotect are huge sources of delay, slowness, resource usage and breakage. Kernel extensions generally are buggy, slow to be ready for new releases, etc...
Setting up restrictions like disabling iCloud sync generally make a Mac run better, not worse.
Setting up a server to delay or restrict updates and patches generally makes a Mac more stable. 
Having IT to help you with backups and procedures to automate things like an erase instal and/or script setting things up like printers and such generally reduce the time you need to manage settings and don't cause any issues with stability.
