If customers or partners are experiencing issues launching their MacOS client, the following can be done to temporarily resolve it:

Multi-user System
1. Log into MyStandard and download a client for your server OR
2. Download a client from Standardinstall.com and manually connect to your server with IP and Port (the version should be the same as your server)

Single-user System
1. Download a new client from Standardinstall.com and restore the latest backup


To resolve, the server needs to be updated to one of the following

8.5 2020-08-13 build 3239
8.5 2020-09-14 build 3833
8.5 2020-10-26 build 4257


Note: this will not fix already broken clients, but will prevent the same thing from happening in the future. Already broken clients need to be fixed using the above methods mentioned.
