DHCP and MacOS problem

Is anybody having problems with MacOS getting ip from DHCP Server on Mikrotik? Mac based systems seem to have trouble getting IP address from Mikrotik. 1/4 of our 1100 tenants complained about this issue then we immediately switched to Windows based DHCP server to fix this problem. I also have a standard linux box running DHCP server for testing and problem still exists. So far only Windows-based or home routers work fine with MacOS but not linux based. Please help.

P.S. I’m running v2.9.6 on our Mikrotik routers.

Does anyone ever have Machintosh users connect through Mikrotik???

yes, of course, lots of. no problems at all!

(if macos 9 is involved … this would be the problem;-)
