Adjust SMB browsing behavior in macOS

Apple has a great tip to speed up you SMB performance on your Mac. This is an Apple recommendation and not a Kodak one. Kodak does not provide support for the Mac operating system.

https://support.apple.com/en-ca/HT208209

In macOS High Sierra 10.13 and later, the default settings for browsing network folders such as Server Message Block (SMB) shares are ideal for most organizations and users. But you can make adjustments to optimize SMB browsing in enterprise environments.

Your Mac determines how each window and its contents should appear by collecting file information such as labels, tags, and other forms of metadata.

In macOS Sierra 10.12 and earlier, your Mac gathers all metadata for the files in a folder, compares it to the folder's .DS_Store file, and then displays the folder's contents. In macOS High Sierra 10.13 and later, this behavior is changed slightly: If a folder is sorted alphanumerically, the contents are displayed immediately, then the Finder collects and compares the rest of the folder's metadata.
Speed up browsing on network shares

To speed up SMB file browsing, you can prevent macOS from reading .DS_Store files on SMB shares. This makes the Finder use only basic information to immediately display each folder's contents in alphanumeric order. Use this Terminal command:

defaults write com.apple.desktopservices DSDontWriteNetworkStores -bool TRUE

Then log out of your macOS account and log back in.

To reenable sorting, use this command:

defaults write com.apple.desktopservices DSDontWriteNetworkStores -bool FALSE

Security Alert for all Windows users

Alert message for all Windows users:

PrintNightmare, Critical Windows Print Spooler Vulnerability
06/30/2021 05:32 PM EDT

The CERT Coordination Center (CERT/CC) has released a VulNote for a critical remote code execution vulnerability in the Windows Print spooler service, noting: “while Microsoft has released an update for CVE-2021-1675, it is important to realize that this update does not address the public exploits that also identify as CVE-2021-1675.” An attacker can exploit this vulnerability—nicknamed PrintNightmare—to take control of an affected system.

We encourage administrators to disable the Windows Print spooler service in Domain Controllers and systems that do not print. Additionally, administrators should employ the following best practice from Microsoft’s how-to guides, published January 11, 2021: “Due to the possibility for exposure, domain controllers and Active Directory admin systems need to have the Print spooler service disabled. The recommended way to do this is using a Group Policy Object.”
