OS X Lion v10.7.4 Update Issues

Last week Apple pushed out a combined OS X Lion and security update. It’s still being pushed out through the Software Update service. While most third-party applications appear to be playing well with the update, a number of serious compatibility issues have been reported, including problems mounting external SATA drives and software RAID volumes.

OS X Lion v10.7.4 Update appears to have a number of attractive fixes for users in a Windows server environment, including improved reliability of binding and logging into Active Directory accounts, and when connecting to a WebDAV server. It appears to fix a longstanding bug for issues that may prevent files from being saved to an SMB server.

However, a number of storage vendors have reported problems with mounting external SATA storage following the update. In a Macintouch post, a Sonnet Technologies tech advised customers to wait on the update based on a number of support calls. However, the company hadn’t been able to replicate the issue.
