Upgrade to Mountain Lion.
Over the past few weeks we’ve had customers inquire about upgrading their machines to OS X 10.8 Mountain Lion. There are a few known issues that we’d like to share along with some tips & tricks. Keep in mind this is just what we’ve come across so far and there very well may be other issues we haven’t seen yet. In general it’s a good idea to wait to a 10.x.1 or 10.x.2 release before upgrading, especially a remote machine.
- Download Mountain Lion from the App Store
- Upgrade can take over 45 minutes
- Do not power cycle machine during upgrade
- VNC window can be left open, it will come back after the upgrade is complete
- Patience is key
- Web sharing is gone – Click here to fix
- Bonjour advertising is re-enabled – Click here on how to disable it
- Download Server.app from App Store after upgrade
- Make note of share points before upgrade – Info
- DHCP & NAT are no longer included, if you currently use those for VPN you may not want to upgrade
- Work group manager can be found here
- Firewall is no longer in Server.app (ipfw deprecated) PF GUI Management can be found here
- New CLI command called ‘serverinfo’ for querying server details/versions
Fresh Install Notes:
- After a fresh install of Mountain Lion, sharing preferences show remote login and screen sharing enabled (remains of installer). After a reboot they are not.
- Installer won’t accept multiple DNS servers, can be added after installation in Network preferences.
- Overall there seems to be more stability in general with Screen Sharing/VNC.
