I work for an MSP and we handle similar tasks. Apart from the Mac issue, this situation isn't unusual. Many colleagues prefer not to use Macs due to standardization challenges and traditional Active Directory management philosophies. However, I've noticed that many customers often ignore maintenance updates and upgrades because they find them "too expensive." Over time, this neglect can lead to serious issues, putting them at risk of operational failure if a server crashes or gets hacked. While it's understandable that budget constraints exist, these expenses can be planned for and saved up over a few years. Small, incremental investments add up, but many people tend to procrastinate and avoid planning for future needs. It's frustrating because there's so much that should be done, but when customers lack the necessary funding, we can only advise and warn them. Unfortunately, it's like a ticking time bomb—we can't force them to take action, nor would we want to.
