Mac OS X 10.9 Mavericks



We are still observing Active Directory binding issues with Mavericks, but many of the issues below appear to be resolved. We will continue to test and keep folks posted. Issues below remain to assist folks accordingly, but will potentially be rewritten to reflect resolved issues. Notably, most issues are due to vendors software - Mountain Lion offers the least amount of university/vendor issues at this time.


At this time, the University of Houston Information Technology recommends that you do not upgrade to Mavericks, since many applications do not function properly. New Apple desktops and portables come equipped with Mavericks, we will continue to test the OS X with each departments IT staff to provide efficient support.  



Historically, software downgrades are not possible, because the firmware is modified during OS X installation i.e., once you update you cannot revert back.


Please know that we are working with IT Managers from multiple departments, allowing us to test Mavericks in multiple environments. We will continue to share our findings with IT Managers.


For questions or problems, email,, call 713-743-1411, or contact your IT Manager.



Understand that the site data can and will change overtime. Feel free to check the software companies website to check the integrity of 10.9 releases and potential unresolved issues. If an update is verified, please email with the findings and the source URL. 

UIT continues to test Mavericks and that any applicable incompatibility findings and/or updated information should be mailed to Also note, that OSX updates, such as 10.9.1, have the potential to “reset” certain parameters of our testing, depending on what modifications are made to the OSX content.


Mavericks - Useful information

Hardware requirements: (same as OS X 10.8)

Application Compatibility:

RoaringApps is a good resource to access collaborative knowledge about both OSX and iOS software compatibility. It is important to mention that this site is a resource, accuracy is not guaranteed, findings may differ in the UH environment, and each OSX software update can result in software incompatibility. Keep this in mind before updating your personal machines.


Time Machine and Backup Information

If you update to Mavericks, do not backup your device with the same Time Machine disk until you are certain that you ensure complete integrity for all application files. Doing so may result in an inability to retrieve certain files. 

Once you backup the device, in some cases, you cannot convert the data, as well as an inability to revert back due to firmware changes. (Very significant for OSX 10.6.8, because rosetta is not included with 10.7 + OSX releases.)

Virtual management software i.e., Parallels, should be backed up independently using Winclone, and should be excluded from Time Machine in most cases.


Mavericks - Known Issues


Issue: While using Mavericks newly coded SMB2 stack, connecting to NAS/Windows shares results in timely login issues, as well as an occasional inability to modify File/Folder permissions for all associated users.

Workaround: Force your connection to use SMB1 by typing cifs://servername/sharename, instead of smb://server/sharename when connecting to a Windows or NAS share.

*UH Enterprise System Administrators have have been informed of this issue.


Mac Mail - Exchange mail downloads slowly or does not download in 10.9

Workaround: Escalated case to Apple Senior Engineers - pending solution.

-Addressed issue that may have caused unread counts to be inaccurate. 


Saving to a Windows share: “Safe Save” -

Issue: Saving to a Windows share from some applications may not be possible without a workaround, because of “safe save,” a feature that modifies the file to automate real-time saving.

Workaround: Save the data locally and then copy & paste the data to the share.


Network shares - after updating, the automount feature may not work.

Current Resolution/workaround: 

Follow these steps to prevent prompts to unlock the Local Items keychain.
