Upgrading to MAC 10.10 prevents the SentriLock Card Utility program from renewing your SentriCard.
SentriLock would like all MAC users to be aware that upgrading to the new MAC OSX 10.10 operating system will cause various errors with the Card Utility program and will fail to renew the SentriCard.
SentriLock’s IT department is working to resolve the issue. Once we have the resolution in place and have tested it, we will send out the update immediately with instructions.
We apologize for any inconvenience this has caused.
